Answer:
Explanation:
As a skydiver falls, he accelerates downwards, gaining speed with each second. The increase in speed is accompanied by an increase in air resistance. This force of air resistance counters the force of gravity.
Answer:
most commonly occurs because of the frequent pumping of water from the ground.
Explanation:
Answer:
<h2>2 m/s²</h2>
Explanation:
The acceleration of an object given it's velocity and time taken can be found by using the formula

v is the velocity
t is the time taken
From the question we have

We have the final answer as
<h3>2 m/s²</h3>

Answer:
Onda electromagnética
Explanation:
Las ondas mecánicas requieren un medio material para la propagación, mientras que las ondas electromagnéticas no requieren un medio material para la propagación.
Generalmente, las ondas electromagnéticas se mueven con una velocidad muy alta.
Todas las ondas electromagnéticas se denominan colectivamente luz y tienen una velocidad común de 3 × 10 ^ 8 m / s en el aire.
Ninguna onda mecánica tiene una velocidad tan alta en el aire.
