Answer:

Option A.

Explanation:

The correct answer is Option A.

The car uses energy to move.

A car is a machine that converts energy locked in fuel like petrol or diesel and turn it into mechanical energy.

The energy produced from the combustion of gasoline is then used to move the shaft, which sends the power to the rear axle and the wheel starts to move.

How can you verify the archimedes principle?

Ipatiy [6.2K]

Answer:

It is found that W1 - W2 loss in weight of solid when immersed in water is equal to the weight of the water displaced by the body. This verifies Archimedes' principle.

Ainat [17]

Answer:

A force is any interaction that causes a mass to change its velocity (accelerate).

Weight is a special case of force. Weight is when a mass is accelerated by gravity.

bezimeni [28]

Answer:

15.325 m/s

11.9702153415 m

9.81 m/s²

Explanation:

t = Time taken

u = Initial velocity

v = Final velocity

s = Displacement

a = Acceleration

g = Acceleration due to gravity = 9.81 m/s² = a

$s=ut+\frac{1}{2}at^2\\\Rightarrow u=\dfrac{s-\frac{1}{2}at^2}{t}\\\Rightarrow u=\dfrac{-46-\frac{1}{2}\times -9.81\times 5^2}{5}\\\Rightarrow u=15.325\ m/s$

The initial velocity of the egg is 15.325 m/s

$v^2-u^2=2as\\\Rightarrow s=\dfrac{v^2-u^2}{2a}\\\Rightarrow s=\dfrac{0^2-15.325^2}{2\times -9.81}\\\Rightarrow s=11.9702153415\ m$

The maximum height is 11.9702153415 m

At the highest point velocity is zero.

Magnitude of acceleration on a freely falling body is always g = 9.81 m/s²
