Explanation: Water is a renewable resource there is so much of it and it just keeps circulating through the system it doesn't run out.
A
Excitation to a higher energy state requires energy which is absorbed from the electromagnetic waves applied.
9.3 x 10⁻⁶N
Explanation:
Given parameters:
Mass 1 = 70kg
Mass 2 = 2000kg
distance = 1m
Unknown:
force between them =
Solution:
The force between the two masses will be a gravitational force of attraction.
F = 
G is universal gravitation constant = 6.67430×10−¹¹ N⋅m²/kg²
r is the distance between the two masses
Substituting the parameters:
F = 
= 9.3 x 10⁻⁶N

Answer: A. It gives off a range of wavelengths of electromagnetic radiation that depends on its temperature.
Explanation: Quizzed
Sound though open space (and other compressible media) is composed of compression waves. Lack of any such media, such as the vacuum of space means the sound waves have nothing to propagate through. So there would be no sound. <span>it's also virtually impossible since there's no electricity</span>
