Which of these is not a conservative force and does not have a form of potential energy connected with it?

What is the force on a 1670kg elevator accelerating at 6m/s square?

marshall27 [118]

As per Newton's 2nd law

we know that

$F = ma$

it is product of mass and acceleration

here we know that

$m = 1670 kg$

also we know that

$a = 6 m/s^2$

so from above equation we have

$F = 1670 * 6$

$F = 10020 N$

so the force here will be 10020 N

A quantity of gas has a volume of 0.20 cubic meter and an absolute temperature of 333 degrees kelvin. When the temperature of th

Nesterboy [21]

Answer:

Option C is the correct answer.

Explanation:

By Charles's law we have

V ∝ T

That is

$\frac{V_1}{T_1}=\frac{V_2}{T_2}$

Here given that

V₁ = 0.20 cubic meter

T₁ = 333 K

T₂ = 533 K

Substituting

$\frac{V_1}{T_1}=\frac{V_2}{T_2}\\\\\frac{0.20}{333}=\frac{V_2}{533}\\\\V_2=\frac{0.20}{333}\times 533=0.3198m^3$

New volume of the gas = 0.3198 m³

Option C is the correct answer.

The man is standing on the plank. Then he is pulling the rope towards himself. He pushes the plank forward with the legs so that he can pull the rope backwards.

The man is standing on the plank. Then he is pulling the rope towards himself. He pushes the plank forward with the legs so that he can pull the rope backwards. So the friction f acts in the forward direction for the plank. Also f acts in the opposite direction on the man. The tension T in the rope is 100 N (given). Let the friction force = f Newtons.

The man is standing on the plank. Then he is pulling the rope towards himself. He pushes the plank forward with the legs so that he can pull the rope backwards. So the friction f acts in the forward direction for the plank. Also f acts in the opposite direction on the man. The tension T in the rope is 100 N (given). Let the friction force = f Newtons.Let the common acceleration = a m/s^2

Man: net force = T - f = m a = 50 a 

net force = T - f = m a = 50 a 

Plank: net force = T + f = m a = 100 a

net force = T - f = m a = 50 a 

Plank: net force = T + f = m a = 100 a

As T = 100 N, a = 4/3 m/s^2 and f = 100/3 Newtons.

The friend who has the greater displacement is the one who takes the longest path.

<h3>What is displacement?</h3>

The displacement is the shortest distance travelled by the particle. It is the vector quantity which re[presents both the magnitude and direction.

Given, two friends leave a movie theater and take different buses to the same ice cream shop. One bus takes a longer route driving on a high-speed highway, while the other takes a shorter route on lower-speed local roads.

According to the definition. the displacement is neither larger not shorter but it is the shortest distance traveled by the person or particle.

Thus, friend who has longer path has larger displacement.
