Answer:
Explanation:
Our lunar companion rotates while it orbits Earth. It's just that the amount of time it takes the moon to complete a revolution on its axis is the same it takes to circle our planet — about 27 days. As a result, the same lunar hemisphere always faces Earth.
Answer:
observe o gráfico abaixo que mostra o número de internação em um hospital no município no período de 1960
As per Newton's II law we know that
here F = force applied
m = mass of object = 2 kg
a = acceleration = 2 m/s^2
now as per above formula we will have
so here applied force on the ball will be 4 N
Answer:
most common energy transformations is the transformation between potential energy and kinetic energy. In waterfalls such as Niagara Falls, potential energy is transformed to kinetic energy. The water at the top of the falls has gravitational potential energy. As the water plunges, its velocity increases.
Explanation:
Hope this helps you
( I got this from transformation and conservation article)
Answer:
Balanced forces.
Explanation:
Forces that are opposite in direction, and, equal in size do not cause a change in motion or position are known as balanced forces. When it is applied to an object at rest, the object will not show any movement.
A good example of a balanced force is when we are trying to push a wall, the wall will push back with an opposite but equal force, so, this time neither the wall nor you will move.
