what is the magnitude of the force exerted by the biceps fbiceps ? what is the magnitude of the force exerted by the elbow felbow ? express your answers in newtons separated by a comma.
Answers
The force exerted by the biceps and the elbow is 239.9 N and 215.89 N respectively.
When we use only your forearms to lift an object, assume that your biceps are the main muscle that lifts your arm. Suppose the weight of the forearm he is 1.50 kg. If the biceps is attached to the forearm 2.50cm from the elbow, with the forearm parallel to the floor, flex the biceps to hold a 950g ball on the end of the elbow at a distance of 36.0cm from the elbow.
Against this background,
forearm mass = 1.50 kg
forearm length = 2.50 cm
The weight of the ball is 950 g.
36.0 cm ball spacing
Forearm strength needs to be calculated. Balance Elbow Using
Torque,
Fb x Db = Wf x Df/2 + Wball x Dball
Putting Value,
Fb x .025 = 1.5 x 9.8 x .36/2 + 0
95 x 9.8 x 0.36
Fb = 239.9 N
Now elbow force,
Fb = Fl + Wf + Wb
Fl = Fb - Wf - Wb
Putting value,
Fl = 239 .9 - (1.5 x 9.8 ) - (0.95×9.8)
Fl = 215.89 N.
Therefore the force on the elbow is 215.89 N.

what is conserved for each of the following wind dynamics laws?a) momentum equationb) first law of thermodynamicsc) continuity equation
Answers
a) In the momentum equation, the quantity that is conserved is momentum. Momentum is the product of mass and velocity and represents the quantity of motion. According to the momentum equation, the total momentum of a system remains constant unless acted upon by external forces. This principle is known as the law of conservation of momentum.
b) The first law of thermodynamics, also known as the law of energy conservation, states that energy cannot be created or destroyed but can only be transferred or converted from one form to another. In the context of the first law of thermodynamics, the conserved quantity is energy. The total energy of a closed system remains constant, and any energy transfer or transformation within the system is balanced by an equal and opposite energy transfer or transformation.
c) The continuity equation deals with the conservation of mass or fluid flow. It states that the mass flow rate remains constant within a closed system or a steady flow process. In other words, the rate at which mass enters a system is equal to the rate at which mass exits the system. This principle ensures the conservation of mass and is applicable to various fluid dynamics phenomena, such as fluid flow through pipes or channels.
In summary, the conserved quantities in the wind dynamics laws are momentum in the momentum equation, energy in the first law of thermodynamics, and mass in the continuity equation.

Approximately how long does it take the uterus lining to build up again after menstruation
Answers
The uterus lining is rebuilt by the end of the menstrual period. The rebuilding of the uterus lining starts after menstruation and the lining is typically completely rebuilt by day 14 of the menstrual cycle, which is when ovulation occurs and the uterus is preparing to potentially receive a fertilized egg.
The endometrium is the inner lining of the uterus, and it thickens every month to prepare for pregnancy. After menstruation, the endometrium grows and thickens to prepare for the implantation of a fertilized egg. The cells in the lining multiply and enlarge, and the glands in the lining begin to secrete mucus and other substances that help support the fertilized egg and promote its growth.
The rebuilding of the endometrium usually takes about two weeks after menstruation. This process is closely regulated by hormones such as estrogen and progesterone, which are produced by the ovaries and other parts of the body. These hormones help control the growth and development of the endometrium and other reproductive tissues.

Q9. Two points P and Q on a progressive wave are separated by distance d. The phase difference between P and Q is rad. What is the wavelength?
Answers
Two points P and Q on a progressive wave are separated by distance d. The phase difference between P and Q is rad. The wavelength of the wave would be 8 times the distance between points P and Q.
In a progressive wave, the phase difference between two points is related to the wavelength of the wave. To find the wavelength (λ) given the phase difference (ϕ) and the distance (d) between two points, we can use the formula:
ϕ = 2π(d/λ)
Rearranging the equation to solve for λ, we have:
λ = (2πd) / ϕ
In this case, the phase difference between points P and Q is given as ϕ radians. The distance between these points is denoted by d. By substituting these values into the equation, we can determine the wavelength of the wave.
It's important to note that the phase difference is typically measured in radians, and one complete wave cycle corresponds to 2π radians.
For example, let's say the phase difference between points P and Q is π/4 radians, and the distance between them is d. Using the formula above, the wavelength would be:
λ = (2πd) / (π/4)
λ = (8πd) / π
λ = 8d
This calculation demonstrates how the phase difference and distance between points on a wave are related to the wavelength. By knowing the phase difference and distance, we can determine the wavelength of the wave using the formula derived from the wave's periodic nature.

You make a 50:50 mixture of benzoic acid and salicylic acid. what is most likely to happen to the melting point of the mixture?
Answers
When you make a 50:50 mixture of benzoic acid and salicylic acid, the most likely outcome is a decrease in the melting point of the mixture. This is due to the phenomenon known as eutectic behavior.
Eutectic behavior occurs when two substances with different melting points are combined in certain proportions. In this case, benzoic acid has a higher melting point than salicylic acid. When they are mixed together in equal amounts, a eutectic mixture is formed.
The eutectic mixture has a lower melting point than either of the pure substances. This is because the two substances interact at the molecular level, disrupting the crystal lattice structure and making it easier for the mixture to melt.
By creating a 50:50 mixture of benzoic acid and salicylic acid, you are essentially creating a eutectic mixture, which will result in a decrease in the melting point. It's important to note that the extent of the decrease will depend on the specific properties of the two substances involved.

Answers
The voltage expression for vy in the given RC op amp circuit with a stepped voltage can be obtained by considering the time constant. If the time constant is 4-8, and the expression for the voltage across the resistor R is 8 mF, where T is in ms, the expression for vy can be derived.
In the given RC op amp circuit, the voltage across the resistor R is given by the expression vy = vis * (1 - e^(-t/RC)), where vis is the input voltage, t is the time, R is the resistance, and C is the capacitance.
Given that the time constant is 4-8, we can assume that the product of R and C is equal to this time constant. Let's assume RC = τ, where τ lies between 4 and 8.
Substituting RC = τ and the given expression for vis as 8 mF (where T is in ms), we can write the voltage expression as vy = 8 * (1 - e^(-t/τ)).
This expression represents the voltage across the resistor R, labeled as vy in the op amp circuit, as a function of time and the time constant τ.

why is it more difficult to start moving a heavy carton from rest than it is to keep pushing it with constant velocity?
Answers
It is more difficult to start moving a heavy carton from rest than it is to keep pushing it with constant velocity because of static friction.
Static friction refers to the resistance encountered when attempting to initiate the movement of two objects that are in contact with each other but not currently in motion relative to each other. When an object is at rest, the force of static friction acts in the opposite direction to any force applied to it.
In this case, the force applied to the carton is the force needed to start moving it from rest. The force of static friction is greater than the force applied to the carton, making it difficult to start moving the carton from rest.
Once the carton is moving with constant velocity, the force of static friction is no longer acting on it. The only force acting on the carton is the force that is applied to keep it moving at a constant velocity. This force is equal to the force of kinetic friction which is less than the force of static friction.
To summarize, the initial effort required to overcome the static friction between a heavy carton and its resting position is greater compared to the continuous force needed to maintain its constant velocity. The force of static friction is greater than the force applied to the carton, making it difficult to start moving the carton from rest.
Once the carton is moving with constant velocity, the force of static friction is no longer acting on it, and the only force acting on the carton is the force that is applied to keep it moving at a constant velocity.

a 70.0-g arrow, fired at a speed of 115 m/s to the left, impacts a tree, which it penetrates to a depth of 12.2 cm before coming to a stop. assuming the force of friction exerted by the tree is constant, what are the magnitude and direction of the friction force acting on the arrow?
Answers
The magnitude of the friction force is 0.788 N and it is directed to the right.
The friction force acting on the arrow is equal to the force required to stop the arrow and is directed opposite the direction of motion.
The magnitude of the friction force is equal to the product of the mass of the arrow (70.0 g) and the deceleration of the arrow (11.2 cm/s^2).
When the arrow hits the tree, the friction force of the tree will slow down the arrow's motion. The magnitude of this friction force is equal to the product of the mass of the arrow (70.0 g) and the deceleration of the arrow (11.2 cm/s^2).
The direction of the friction force will be opposite to the direction of the arrow's motion.
Therefore, the magnitude of the friction force is 0.788 N and it is directed to the right. This is because the arrow was fired to the left and the friction force must be equal and opposite in order to bring the arrow to a stop.

Answers
the initial velocity of object B was 1.475 meters per second.
What is the law of conservation of momentum?A conservation law states that the total linear momentum of a closed system remains constant through time, regardless of other possible changes within the system.
Given, A is a sphere that is traveling with a velocity of (3.7) m/s and had a mass of 5 kg.
It collides with sphere B and both particles move together with a velocity of (1.4) m/s after the collision.
From the law of conservation:
Momentum will be the same in case of collision
p₁ = p₂
m₁ v₁ = m₂ v₂
Where P₁ = initial momentum of the system,
P₂ = final momentum of the system,
m₁ = mass of the first object,
v₁ = velocity of the first object,
m₂ = mass of the second object
v₂ = velocity of the second object.
In our case,
m₁ = 5 kg
v₁ = 3.7
Since the mass of B is given 4 kg
m₂ = 4 kg
The final mass will be M = m₁ + m₂
M = 4 + 5
M = 9 Kg
Final velocity V = 1.4 m/s
Applying conservation of momentum:
m₁ v₁ + m₂ v₂ = M V
5 * 3.7 + 4 v = 9 * 1.4
18.5 + 4v = 12.6
4v = 18.5 - 12.6
4v = 5.9
v = 1.475
thus, the initial velocity of the object B was 1.475 meters per second.

Calculate, for this car:
i the power necessary to maintain the speed of 15ms-¹,
ii the total resistive force at a speed of 30 ms-¹,
iii the power required to maintain the speed of 30ms-¹.
Answers
Answer:
i) Power = Force * Velocity = 1100 * 15 = 16500 W = 16.5 kW(ii) Find the value of k first: F = 400 + k(15^2) k = 28/9 F = 400 +(28/9)(30^2) = 320
Explanation:
P = (400 + k * 15²) * 15
P = (400 + 11250) * 15
P = 11650 Watts
Therefore, the power necessary to maintain the speed of 15ms^-1 is approximately 11650 Watts.
b. The total resistive force at a speed of 30ms^-1 can be found by substituting 30 for v in the force equation:
F = 400 + k * 30^2
F = 12000 N
Therefore, the total resistive force at a speed of 30ms^-1 is approximately 12000 N.
c. The power required to maintain the speed of 30ms^-1 can be found using the same equation as in part a:
P = (400 + k * 30^2) * 30
P = (1500 + 600000) * 30
P = 625000000 Watts
Therefore, the power required to maintain the speed of 30ms^-1 is approximately 625000000 Watts. This is a very large amount of power and would require a significant amount of energy to maintain.
