Answer:
We define a vector as an object with a length and a direction.With no length, the zero vector is not pointing in any particular direction, so it has an undefined direction.

Answer:
The kinetic energy is 303178 Joule
Explanation:
We must change the speed units to m / s =
1km ---- 1000meters
1h ----- 3600 seconds
v = (95km 1000m / km) / (1h x 3600s / h) = 26, 4 m / s
We use the Kinetic Energy formula: Ec = 1/2 m x v ^ 2
Ec = 1/2 x 870 kg x (26, 4) ^ 2 = 303177, 6 Joule
Answer:
(1.) gamma rays. (2.) X-rays. (3.) ultraviolet. (4.) visible light. (5.) infrared.
(6.) radio waves
Explanation:
Notice that these wavelengths span an enormous range. The wavelengths of gamma rays can be smaller than the size of an atomic nucleus, while the wavelengths of radio waves can be many meters (or even milometers) long. Visible light spans only a very narrow range of wavelengths, from about 400 nano meters at the blue (violet) end to about 700 nano meters at the red end.
