Newton's second law of motion states that

D. the force acting on a body equals the rate of change of momentum

Explanation:

Newton's second law of motion states that the force acting on a body is equal to the product between the mass of the body and its acceleration. Mathematically:

$F=ma$

where

F is the force

m is the mass

a is the acceleration

We can re-write the acceleration as the rate of change of the velocity:

$a=\frac{\Delta v}{\Delta t}$

So we can re-write the equation as

$F=\frac{m\Delta v}{\Delta t}$

However, the term $m\Delta v$ represents the change in momentum of the body, $\Delta p$ (assuming its mass to be constant). Therefore, we can further rewrite the equation as

$F=\frac{\Delta p}{\Delta t}$

which means that the force acting on a body equals the rate of change of momentum (option D).

If time is tripled and work remains the same the power will.

VMariaS [17]

Answer:

power will three times decrease (one-third)

Explanation:

P = W / t

thus when work is constant, power is inversely proportional to time

so, when time is tripled, power is decreased to one-third

A painter sits on a scaffold that is connected to a rope passing over a pulley. The other end of the rope rests in the hands of

Doss [256]

Solution :

a). From Newtons second law,

F = ma

The total tension force is 2T.

∴ 2T - (m + M)g = (m+ M)a

Then

$a=\frac{2T-(m+M)g}{m+M}$

$a=\frac{2\times 600-(52+63)9.8}{52+63}$

$=0.63 \ m/s^2$

b). From the person,

F = ma

T - Mg + N = Ma

or N = Ma + Mg - T

= (63 x 9.8) + (52 x 9.8) - 600

= 617.4 + 509.6 - 600

= 527 N

Why is newton's first law of motion sometimes called the lae of inertia?

Masja [62]

Newton's 1st law of motion states that <span>an object at rest stays at rest and an object in uniform motion along a straight line stays in motion unless acted upon by an unbalanced force.
This law talks about the tendency of an object to resist any change in its state of rest or uniform motion, this is called Inertia. Thus Newton's 1st law of motion is also called the Law of Inertia</span>
