A cartoon shows two friends watching an unoccupied car in free fall after it has rolled off a diff. One friend says to the other
olga55 [171]

Answer:

The statement is not correct.

Explanation:

To know if the statement is correct, we shall determine the velocity of the car after 3 s. This is illustrated below.

Data obtained from the question include:

Initial velocity (u) = 0 m/s

Acceleration due to gravity (g) = 9.8 m/s²

Time (t) = 3 s

Final velocity (v) =?

v = u + gt

v = 0 + (9.8 × 3)

v = 0 + 29.4

v = 29.4 m/s

Thus, the velocity of the car after 3 s is 29.4 m/s.

Hence, the statement made by the friend is not correct as the car has a falling velocity of 29.4 m/s after 3 s.

What is the difference between condensation and precipitation
Alexxandr [17]

Explanation:

The water cycle is based on three parts;

1. Evaporation

2. Condensation

3. Participation

Condensation:

It is the process in which water vapor changes into liquid water or in other words, it is the transition from the gaseous state to liquid state.

Precipitation:

It is the process in which any liquid or frozen water such as snow that forms in the atmosphere and falls back to the Earth

Condensation depends on temperature and pressure whereas precipitation depends on the temperature and the concentration of the solution.

In attempting to pull a 1500-kg car out of a ditch, Arnold exerts a force of 300 N for three seconds, Bob exerts a force of 500
SpyIntel [72]

Answer:

Bob provided the greatest impulse.

Explanation:

Given:

Arnold exerts force = 300 N for 3 seconds

Bob exerts force = 500 N for 2 seconds

Cecil exerts force = 200 N for 4 seconds.

Find:

Highest impulse

Computation:

Impulse = Force × TIme

Arnold provides impulse = 300 N × 3 seconds = 900 N/s

Bob provides impulse = 500 N × 2 seconds = 1,000 N/s

Cecil provides impulse = 200 N × 4 seconds = 800 N/s

Therefore, Bob provided the greatest impulse.

The bones of the forearm (radius and ulna) are hinged to the humerus at the elbow. The biceps muscle connects to the bones of th
sertanlavr [38]

Answer:

The force exerted by the biceps is 143.8 kgf.

Explanation:

To calculate the force exerted by the biceps, we calculate the momentum in the elbow.

This momentum has to be zero so that her forearm remains motionless.

Being:

W: mass weight (6.15 kg)

d_W= distance to the mass weight (0.425 m)

A: weight of the forearm (2.25 kg)

d_A: distance to the center of mass of the forearm (0.425/2=0.2125 m)

H: force exerted by the biceps

d_H: distance to the point of connection of the biceps (0.0215 m)

The momemtum is:

H*d_H-A*d_A-W*d_W=0\\\\H=(A*d_A+W*d_W)/d_H\\\\H=(2.25*0.2125+6.15*0.425)/0.0215\\\\H=(0.478125+2.61375)/0.0215\\\\H=3.091875/0.0215=143.8

The force exerted by the biceps is 143.8 kgf.
