Objects in free fall accelerate due to ______

Charra [1.4K]

Answer:

The correct answer is A.

Objects in free fall accelerate due to <u>gravity</u>.

Explanation:

Momentum can help an object to keep its state of motion at a constant velocity when no external force is applied. It can never accelerate the object.

According to the laws of motion, we know that acceleration is produced in a body only when a Force is applied in the direction of motion of body.

During a free fall, only the force of gravity is acting on an object and that too in the direction of its motion. Hence, the acceleration produced in a free falling object is due to gravity.

a 2.00 kg friction-less block is attached to an ideal spring with force constant 315 N/m.Initially, the spring is neither stretc

Setler [38]

Answer

given,

mass of block, m = 2 Kg

spring constant, k = 315 N/m

speed of the block, v = 12 m/s

a) Amplitude of the motion

$A = v \sqrt{\dfrac{k}{m}}$

$A =\dfrac{12}{\sqrt{\dfrac{315}{2}}}$

A = 0.956 m

b) maximum acceleration of the block

$a_{max}= A \dfrac{k}{m}$

$a_{max}= 0.956\times \dfrac{315}{2}$

$a_{max}= 150.57\ m/s^2$

c) maximum Force

$F_{max} = m a_{max}$

$F_{max} = 2\times 150.57$

$F_{max} = 301.14\ N$

A railroad car containing an angry bull is standing onthe

nata0808 [166]

Answer:

$v_{f}$ = - M / m v

Explanation:

We must define a system formed by the wagon and the torro, in this case the forces of the movement are internal, so the moment is preserved, write the moment in two moments

Initial. Before the bull's movement, in this case the two are still

p₀ = 0

Final. The bull is moving

$p_{f}$ = M v + m $v_{f}$

p₀ = $p_{f}$

0 = M v + m $v_{f}$

We cleared the train speed

$v_{f}$ = - M / m v

The negative sign indicates that the train moves in the opposite direction of the bull

The ideal gas law is represented by PV=nRT. As volume is held constant and the temperature increases, how would the pressure be

nydimaria [60]

The pressure would increase as per Charle's Law, therefore the correct answer is option 4.

<h3>What is an ideal gas?</h3>

It is an imaginary gas for which the volume occupies by it is negligible, this gas does not exist in a practical situation and the concept of an ideal gas is only the theoretical one,

PV = nRT

As given in the problem statement we have to find out if the volume is held constant then what would happen to the gas if the temperature is increased,

For constant volume, the pressure of a gas is directly proportional to the temperature of the gas,

Thus, the pressure would increase as per Charle's Law, therefore the correct answer is option 4.
