Answer:

A.Acceleration equals change in velocity divided by time.

Explanation:

We have to determine that how to calculate acceleration

We know that acceleration  is the change in the velocity with time.

Mathematical formula,

If u=Initial velocity

v=Final velocity

t=Time taken in seconds

A=\frac{change\;in\;velocity}{time}=\frac{v-u}{t}

S.I units of acceleration =m/s^2

Hence, the acceleration equal change in velocity divided by time.

Therefore, option A is true.

Answer:A.Acceleration equals change in velocity divided by time.

A mass hanged on a spring scale. what is the force exerted by gravity on 700g ?
Ipatiy [6.2K]

Answer:

6.86 N

Explanation:

Applying,

F = mg............... Equation 1

Where F = Force exerted by gravity on the mass, m = mass, g = acceleration due to gravity

Note: The Force exerted by gravity on the mass is thesame as the weight of the body.

From the question,

Given: m = 700 g = (700/1000) = 0.7 kg

Constant: g = 9.8 m/s²

Substitute these values into equation 1

F = 9.8(0.7)

F = 6.86 N
