The altitude of the satellite is 883.89 km

Generally, The Rayleigh criterion for resolution states that the minimum angle, θ, between two point sources that can be resolved is given by:

θ = 1.22 * λ / D

where

λ is the wavelength of light and

D is the diameter of the lens.

The minimum distance, d, between two point sources that can be resolved is given by:

d = θ * L

where

L is the distance from the lens to the image.

Given the green lights have a wavelength of 508 nm, we can convert it to meters:

λ = 508 * 10^-9 m

Given the diameter of the lens is 49.8 cm, we can convert it to meters:

D = 49.8 cm * (1 m / 100 cm)

= 0.498 m

Using the Rayleigh criterion, we can find the minimum resolvable angle:

θ = 1.22 * λ / D

= 1.22 * 508 * 10^-9 / 0.498

= 1.24449799*10^{-6} radians

We know the lights on the satellite are spaced 1.1 m apart, so:

d = 1.1 m

Solving for the distance from the lens to the image, L:

L = d / θ

= 1.1 m / 1.24449799*10^{-6} radians

=883890.53 m

Finally, converting the distance to kilometers:

L = 883890.53 m * (1 km / 1000 m)

= 883.89 km

Many non-spontaneous biochemical reactions couple with other reactions, which supply enough free energy to drive them all. This statement is True. A non-spontaneous reaction is a reaction that requires energy to proceed, also known as an endergonic reaction.

It has a positive ∆G, which means that it absorbs free energy rather than releasing it. On the other hand, a spontaneous reaction is a reaction that proceeds on its own, releasing free energy. It has a negative ∆G, which means that it releases free energy and requires no additional energy input to proceed. A coupled reaction is a chemical reaction in which the free energy released by one reaction drives another reaction that requires free energy. The two reactions must be coupled together in a way that enables them to share free energy, resulting in the spontaneous progression of the entire system.

As a result, many non-spontaneous biochemical reactions couple with other reactions that supply enough free energy to drive them all. The most common example of coupled reactions is the coupling of ATP hydrolysis with non-spontaneous reactions. This coupling can provide the energy required for cellular processes like muscle contraction, nerve impulse transmission, and protein synthesis. Furthermore, the coupled reactions serve as a means of energy conservation in living organisms.

To study vectors it is best to select a coordinate system and manipulate it in that coordinate system and the component of A in x is 0.9396 while in y it is 0.342.

An item with both magnitude and direction is referred to be a vector.

A vector can be visualized geometrically as a straight spline, with a pointing in the orientation and a length equal to the value of the vector.

A vector has magnitude and direction so we can form a vector coordinate system and manipulate each vector in that such that it will be clear to study all vectors.

Given the vector A,

Magnitude |A| = 1 units

The angle of inclination from the x-axis is 20°.

Component of A in the x-axis ⇒

|A|cos20° = 1(0.9396) = 0.9396

Component of A in the y-axis ⇒

|A|sin20° =1(0.342) = 0.342

Hence "The component of A in x is 0.9396 while in y it is 0.342".

Answer:

Mass = 58.98 kg

Explanation:

Given the following data;

Velocity = 40.3 km/h to meters per seconds (m/s) = 40.3*1000/3600 = 11.19 m/s

Momentum = 660kgm/s

To find the mass;

Momentum can be defined as the multiplication (product) of the mass possessed by an object and its velocity. Momentum is considered to be a vector quantity because it has both magnitude and direction.

Mathematically, momentum is given by the formula;

\( Momentum = mass * velocity \)

Substituting into the equation, we have

660 = mass * 11.19

Mass = 660/11.19

Mass = 58.98 kg

According to the question,

We know,

→ \(Momentum = Mass\times Velocity\)

or,

→ \(Mass = \frac{Momentum}{Velocity}\)

By substituting the values, we get

             \(= \frac{660}{11.19}\)

             \(= 58.98 \ kg\)

Speed, being a scalar quantity, is the rate at which an object covers distance. The average speed is the distance (a scalar quantity) per time ratio. ... Velocity is the rate at which the position changes. The average velocity is the displacement or position change (a vector quantity) per time ratio.

Answer:

It’s both I and II

Explanation:

Speed refers to how fast something goes by using the equation distance/time. So it only uses distance and time.

On the other hand velocity is basically speed, so it uses distance/time, but the only difference is velocity uses direction.

Answer:

Exposure occurs when a person comes into contact with hazard

Answer:

D

Explanation:

It says constant positive linear acceleration, which means that the velocity increases at a constant rate.

The value of m2 for both the blocks which move with the same speed but in opposite directions after the collision is m1 or 0.5 kg.

For the blocks to move with the same speed but opposite directions, the mass of the second block, m2, must be equal to m1, or 0.5 kg.

After the collision, the speed of either block is v1, or 2.0 m/s.

The fraction of the original kinetic energy (KE) transferred from m1 to m2 is equal to the ratio of the two masses, m2/m1. Therefore, the fraction of KE transferred is 1.

After the blocks hit the springs and bounce back, they will both have a velocity of 0 m/s, since they will be moving in opposite directions with the same speed.

Chewing is an example of mechanical digestion.Mechanical digestion refers to the process by which food is physically broken down into smaller pieces to improve digestion and absorption.

The process begins in the mouth and is carried out by a number of organs such as the tongue, teeth, and stomach. Chemical digestion occurs next, in which enzymes break down food molecules to their essential components, allowing them to be absorbed into the bloodstream and delivered to the cells that need them.

What is an example of mechanical digestion?As stated earlier, mechanical digestion involves the physical breakdown of food into smaller particles. Here are some examples of mechanical digestion:Chewing - Your teeth grind food into smaller pieces, making it easier to digest and absorb.

Your saliva, which contains enzymes that start the chemical digestion process, also softens the food and helps to break down starch into simpler sugars.Grinding - After you swallow, your food moves to the stomach, where it is further broken down by contractions of the stomach muscles.

Mixing - The stomach's muscular walls contract to create churning movements that mix food with gastric juices, resulting in a semi-solid substance known as chyme that can be transported to the small intestine for further digestion and absorption.In conclusion, chewing is an example of mechanical digestion.

Answer:

Option B. 2 A.

Explanation:

The following data were obtained from the question:

Resistance 1 (R1) = 1 Ω

Resistance 2 (R2) = 2 Ω

Resistance 3 (R3) = 3 Ω

Potential difference (V) = 12 V.

Current through the 3 Ω (I3) =?

Next, we shall determine the total resistance of the circuit.

This can be obtained as follow:

Resistance 1 (R1) = 1 Ω

Resistance 2 (R2) = 2 Ω

Resistance 3 (R3) = 3 Ω

Total resistance (R) =.?

R = R1 + R2 + R3

R = 1 + 2 + 3

R = 6 Ω

Next, we shall determine the current flowing in the circuit.

This can be obtained as follow:

From ohm's law,

Voltage (V) = current (I) x resistance (R)

V = IR

Potential difference (V) = 12 V.

Resistance (R) = 6 Ω

Current (I) =?

V = IR

12 = I x 6

Divide both side by 6

I = 12/6

I = 2 A.

Since the circuit is in series connection, therefore, the same current will flow through each resistor.

Therefore, the current through the the 3 Ω load is 2 A.

The acceleration of the particle after 1 minute is \(18 units/min^2.\)

To find the acceleration, we need to differentiate the position function twice with respect to time.

Given:

\(s(t) = 2t^3 + 3t^2 + t\)

To find the velocity, differentiate s(t) with respect to t:

\(v(t) = d/dt [2t^3 + 3t^2 + t]\)

\(v(t) = 6t^2 + 6t + 1\)

To find the acceleration, differentiate v(t) with respect to t:

\(a(t) = d/dt [6t^2 + 6t + 1]\)

\(a(t) = 12t + 6\)

Now, substitute t = 1 to find the acceleration after 1 minute:

\(a(1) = 12(1) + 6\)

\(= 12 + 6\)

\(= 18\)

Therefore, the acceleration after 1 minute is \(18 units/min^2\)

The binding energy is 49K MeV.

To calculate the binding energy of an atom of 49K, we first need to find the mass defect. The mass defect is the difference between the sum of the masses of individual protons and neutrons and the actual mass of the nucleus (the given mass of 49K).

49K has 19 protons and 30 neutrons (49 - 19). We'll use the given masses to find the mass defect:

mass_protons = 19 * 1.007825 amu
mass_neutrons = 30 * 1.008665 amu
mass_nucleons = mass_protons + mass_neutrons

mass_defect = mass_nucleons - 48.965514 amu

Now, we'll convert the mass defect to MeV using the given conversion factor:

binding_energy = mass_defect * 931.5 MeV/amu

This will give you the binding energy in MeV per atom for 49K.

About -420.97 MeV is the binding energy per atom for the element 49K. It should be noted that the negative sign signifies that energy is released as the nucleus forms, indicating a stable nucleus.

Explanation:

To find the partial derivative of the function with respect to x, ∂/∂x(x^3 * e^(4xy)),

Step 1: Identify the terms and variables involved in the function.
In this case, we have the terms x^3 and e^(4xy).

Step 2: Apply the product rule for derivatives.
The product rule states that for functions u(x) and v(x), the derivative of their product is given by:

(d(uv)/dx) = u(dv/dx) + v(du/dx)
Here, let u(x) = x^3 and v(x) = e^(4xy).

Step 3: Find the partial derivatives of u(x) and v(x) with respect to x.
For u(x) = x^3, we have du/dx = 3x^2.
For v(x) = e^(4xy), we have dv/dx = (4y)e^(4xy) (using the chain rule).

Step 4: Apply the product rule using the partial derivatives found in Step 3.
Using the product rule, we get:
(∂/∂x)(x^3 * e^(4xy)) = x^3 * (4y * e^(4xy)) + e^(4xy) * (3x^2)

Step 5: Simplify the expression.
The final simplified expression for the partial derivative with respect to x is:
(∂/∂x)(x^3 * e^(4xy)) = 4yx^3 * e^(4xy) + 3x^2 * e^(4xy)

So, the partial derivative of the function with respect to x is 4yx^3 * e^(4xy) + 3x^2 * e^(4xy).

Of the four thermodynamic quantities listed, enthalpy is the only one that is a state function. A state function is a thermodynamic quantity that depends only on the initial and final states of a system, and not on the path taken to reach those states.

Enthalpy is a state function because it is defined as the sum of the internal energy of a system and the product of its pressure and volume, both of which are state functions.

Energy, work, and heat, on the other hand, are not state functions because they depend on the specific process or path taken to change the state of the system. The amount of work done or heat transferred depends on the specific conditions of the process, such as the pressure, temperature, and volume of the system, as well as the rate at which the work or heat is transferred.
