Wood because it is natural and we use it for furniture but we also burn it for energy.
Answer:
4.5m
Explanation:
Distance is the total length of path traveled or covered by a body.
So distance is a scalar quantity, it only has magnitude but no direction.
Therefore:
Total distance = 3 m + 
(3)
So;
3 + 1.5 = 4.5m
Total distance covered 4.5m by the body.
All electromagnetic radiation ... all wavelengths, all frequencies ... has the
same speed, as long as you're measuring all through the same medium.
The speed is fastest in vacuum ... 299,792,458 meters per second. It's
slower than that in any material, and different in every material.
Answer:
In classical mechanics, kinetic energy (KE) is equal to half of an object's mass (1/2*m) multiplied by the velocity squared. For example, if a an object with a mass of 10 kg (m = 10 kg) is moving at a velocity of 5 meters per second (v = 5 m/s), the kinetic energy is equal to 125 Joules, or (1/2 * 10 kg) * 5 m/s2.
