Answer:

Explanation:

1) Normal force is the upward force applied by the ramp (incline) on the suitcase as the reaction to the downward force of the Weight (Fg) of the suitcase

2)  sorry, can't supply a FBD.  Brainly doesn't have drawing tools available.

3)  Fg = mg = (32 kg)(9.8 m/s²) = 313.6 N

N= y-component of Fg = cos30(313.6 N) = 271.6 N

Ff = (coeff. friction)(N)

3) Ff = x-component of Fg = sin30(313.6) = 156.8 N

4) coeff. friction = Ff/N = 156.8N/271.6N = 0.58

Question:

A roller-coaster vehicle has a mass of 500 kg when fully loaded with passengers.  If the vehicle has a speed of 20.0 m/s at point A, what is the force exerted by the track on the vehicle at this point?

See attachment

Answer:

33700 Newton

Explanation:

Given

\(m = 500kg\\v = 24.0m/s\\r=10m\)

First, we determine the forces acting on mass m.

They are: the force exerted by the track (Fn) and the weight of the vehicle (W)

So, the net force is:

\(F_{net} = F_n - W\)

\(W=mg\)

So:

\(F_{net} = F_n - mg\)

Make Fn the subject

\(F_n = F_{net} + mg\)

Fnet is calculated as:

\(F_{net} = F_c = \frac{mv^2}{r}\) --- i.e. the centripetal force

So:

\(F_n = F_{net} + mg\)

\(F_n = \frac{mv^2}{r} + mg\)

\(F_n = \frac{500 * 24^2}{10} + 500 * 9.8\)

\(F_n = 28800 + 4900\)

\(F_n = 33700N\)

A biophysics experiment uses a very sensitive magnetic-field probe to determine the current associated with a nerve impulse travelling along an axon. if the peak field strength 2 mm from an axon is 6 pt, the peak current carried by the axon is 0.03 A.

The relationship between magnetic field strength and current can be described by the following equation:

B = (μ0/4π) * (2I/r)

where B is the magnetic field strength, μ0 is the permeability of free space, I is the current, and r is the distance from the current.

Solving for I, we get:

I = (B * 4π * r) / (2 * μ0)

Substituting the given values, we have:

I = (6 pt * 4π * 2 mm) / (2 * μ0)

Using the value of μ0 (permeability of free space) as 4π * 10^-7 T·m/A, we get:

I = (6 pt * 4π * 2 mm) / (2 * 4π * 10^-7 T·m/A)

I = 0.03 A

Therefore, the peak current carried by the axon is 0.03 A.

Answer:

1.92 kg of nitrogen.

Explanation:

The following data were obtained from the question:

Heat absorbed (Q) = 384000 J

Note: Heat of vaporisation (ΔHv) of nitrogen = 5600 J/mol

Next, we shall determine the number of mole of nitrogen that absorbed 384000 J.

This is illustrated below:

Q = mol·ΔHv

384000 = mole of N2 x 5600

Divide both side by 5600

Mole of N2 = 384000/5600

Mole of N2 = 68.57 moles

Next, we shall convert 68.57 moles of nitrogen, N2 to grams.

This can be obtained as follow:

Molar mass of N2 = 2 x 14 = 28 g/mol.

Mole of N2 = 68.57 moles.

Mass of N2 =..?

Mole = mass /molar mass

68.57 = mass of N2 /28

Cross multiply

Mass of N2 = 68.57 x 28

Mass of N2 = 1919.96 g

Finally, we shall convert 1919.96 g to kilograms.

This can be achieved as shown below:

1000g = 1 kg

Therefore,

1919.96 g = 1919.96/1000 = 1.92 kg.

Therefore, 1.92 kg of nitrogen were burned off.

Explanation:

According to the data given in the question the net force on the box is of 5 N.

All of the forces that are applied to an object are added up to form the net force. As a consequence of the fact that it (force) is a vector and therefore that two forces with identical magnitudes and opposing directions cancel each other out, the resultant force is the total of the forces, or put another way, the net force is just the total of all the forces.

Given data :

Force on box to the left side (F1) = 15 N

Force on box to the right side (F2) = 20 N

Because both forces are in opposite direction

Hence,

Net force = F2 - F1

Net force = 20 - 15

potential at point A( -776 V)

the potential at point B;( -855 V)

the work done by the electric field on the charge is 198 nJ.

first, we can use Coulomb's law to find the electric field at points A and B due to the two charges:

Electric field at A:

\(E1 = kq1/r1^2\), where k is Coulomb's constant \((9*10^9 Nm^2/C^2),\) q1 is the charge of q1 (+2.4 nC), and r1 is the distance from q1 to A (0.050 m)

\(E2 = k*q2/r2^2\), where q2 is the charge of q2 (-6.5 nC), and r2 is the distance from q2 to A (0.050 m)

The net electric field at A is the vector sum of these two fields:

E_net = E1 + E2

Electric field at B:

\(E1 = kq1/r1^2\), where r1' is the distance from q1 to B (0.080 m)

\(E2 = k*q2/r2^2\), where r2' is the distance from q2 to B (0.060 m)

The net electric field at B is the vector sum of these two fields:

E_net' = E1' + E2'

(a) The potential at point A can be found using the formula:

V_A = kq1/r1 + kq2/r2

where r1 and r2 are the distances from q1 and q2 to A, respectively.

Substituting the given values:

V_A =\((9*10^{9} Nm^2/C^2) * (2.4*10^{-9} C) / (0.050 m) + (9*10^{9} Nm^2/C^2) * (-6.5*10^{-9} C) / (0.050 m)\)

V_A = -776 V

(b) The potential at point B can be found using the same formula as for point A, but with the distances r1' and r2':

V_B = kq1/r1' + kq2/r2'

Substituting the given values:

V_B =\((9*10^{9} Nm^2/C^2) * (2.4*10^{-9} C) / (0.080 m) + (9*10^{9} Nm^2/C^2) * (-6.5*10^{-9} C) / (0.060 m)\)

V_B = -855 V

(c) The work done by the electric field on a charge of 2.50 nC that travels from point B to point A is equal to the change in potential energy of the charge:

ΔU = q * (ΔV)

where q is the charge (2.50 nC), ΔV is the change in potential (V_A - V_B).

Substituting the given values:

\(ΔU = (2.50*10^{-9} C) * (-776 V - (-855 V))\)

ΔU = 198 nJ

Therefore, the work done by the electric field on the charge is 198 nJ.

Explanation:

If the proper voltage is supplied ,the possible causes could be a defective heater or an open limit switch. The correct options are C) the heater is defective or D) the limit switch is open.

When an electric heating element does not get hot despite the proper voltage being supplied, there are a few potential reasons for this issue. Firstly, the heater itself may be defective.

There could be a problem with the heating element, such as a broken or burnt-out filament, a faulty connection, or internal damage. If the heater is defective, it will not generate heat even when the correct voltage is applied.

Alternatively, the limit switch may be open. A limit switch is a safety device designed to shut off power to the heating element if certain conditions, such as excessive temperature or pressure, are detected. If the limit switch is open, it disrupts the circuit and prevents the heating element from receiving power, resulting in no heat production.

It is important to note that the circuit breaker being reset or the fusible link melting would not directly cause the heating element to not get hot. The circuit breaker is a protective device that trips to interrupt the flow of electricity when there is an overload or a short circuit.

Resetting the circuit breaker may be necessary if it has tripped, but it is not the primary cause of the heating element not heating. Similarly, a fusible link melting is typically associated with protecting the circuit from excessive current flow, but it does not directly impact the heating element's functionality.

In summary, if the proper voltage is supplied to an electric heating element and it does not get hot, the likely causes are a defective heater or an open limit switch.

The heater may have internal issues preventing it from generating heat, while the limit switch being open interrupts the power supply to the heating element. Therefore, the correct options are C) the heater is defective or D) the limit switch is open.

The velocity after 2 seconds is 26 m/s. It takes 11.50 seconds to reach a velocity of 40m/s.

Given the equation s(t) = 6t + 5t²

Let's find the velocity after 2 seconds.

(a) Velocity = (ds)/(dt)

Differentiating s(t) with respect to t, we get; ds(t) / dt = 6 + 10t

At t = 2,ds(t) / dt = 6 + 10t = 6 + 10(2) = 26m/s

Therefore, the velocity after 2 seconds is 26 m/s.

(b) We are to find how long it takes for the velocity to reach 40m/s. We know that the initial velocity of the ball, u = 6m/s. Acceleration = gsinθ = 9.81 x sin (angle of inclination) = 9.81 x 0.3 = 2.943 m/s²From the first equation of motion, v = u + at

We know v = 40m/s, u = 6m/s, a = 2.943m/s² and t is what we are to find, hence the equation becomes;40 = 6 + 2.943(t)t = (40 - 6) / 2.943t = 11.50s

Therefore, it takes 11.50 seconds to reach a velocity of 40m/s.

The equation is as follows: E = E° - (RT/nF)ln(Q), where E is the potential of the half-cell, E° is the standard electrode potential, R is the gas constant, T is the temperature in Kelvin, n is the number of electrons transferred in the half-reaction, F is Faraday's constant, and Q is the reaction quotient.

In this case, the half-cell reaction is

Cr₂O₇²⁻(aq) + 14H+(aq) + 6e- → 2Cr₃+(aq) + 7H₂O(l).

The reaction quotient Q can be written as

[Cr3+]^2[H2O]/[K2Cr2O7][H+]^14,

where [Cr3+] and [H+] are the molar concentrations of Cr3+ and H+ ions, respectively, and [K2Cr2O7] is the molar concentration of K₂Cr₂O₇. Plugging in the given values, we get Q = (0.20M)^2(1)/(0.10M)(1.0x10^-4M)^14.

Next, we can calculate the potential of the half-cell using the Nernst equation: E = 1.33V - (0.0257V/K)(ln Q/6) = 1.33V - (0.00428V)ln Q. Substituting the value of Q that we obtained, we get E = 1.33V - 0.00428V ln (4.72 x 10^18) = 0.41V.

Therefore, the Ford Shelby GT 500's horsepower of 760 hp can be converted to watts as follows:

760 hp × 746 watts/hp = 567760 watts

To convert horsepower to watts, you simply need to multiply the number of horsepower by the conversion factor of 746 watts/hp.So, the numeric answer for 760 hp in watts is 567760.

According to the work-energy principle, the work done on an object is equal to the change in kinetic energy. Mathematically, the work-energy principle can be represented as follows:

W = ΔKHere, W represents the work done on the object, and ΔK represents the change in kinetic energy of the object.

The change in kinetic energy can be calculated using the following formula:

ΔK = (1/2)mvf² - (1/2)mvi²

Here, m represents the mass of the object, vi represents the initial velocity of the object, and vf represents the final velocity of the object. In this case, the object is initially at rest (vi = 0), so the formula can be simplified to

:ΔK = (1/2)mvf²

Now, we can use the following kinematic equation to calculate the final velocity of the object:

vf² = vi² + 2ax

Here, a represents the acceleration of the object, x represents the displacement of the object, and vi represents the initial velocity of the object. Plugging in the given values, we get:

vf² = 0 + 2(10 m/s²)(30 m - 10 m)vf² = 400 m²/s²vf = 20 m/s

Now, we can plug in the values of m and vf to calculate the change in kinetic energy:
