Hello There!
Kilo means thousand.
For example:
Kilometer means a thousand meters.
Hope This Helps You!
Good Luck :)
P = m/v
6000 kg/m3 = m/4x10^-4
m = 2.4 kg
P = m/v
5000 kg/m3 = 2.4kg/v
V = 4.8 x 10^-4
0.7N x 10 = 7kg
P = m/v
P = 7/4.8 x 10^-4
P answer = 1458.3
It is right?
The elastic potential energy of the spring is 0.31 J
Explanation:
The elastic potential energy of a spring is given by
where
k is the spring constant
x is the compression/stretching of the spring
For the spring in this problem, we have:
k = 500 N/m (spring constant)
x = 0.035 m (compression)
Substituting, we find the elastic potential energy:

Answer:
If a ray of light hits the surface of a sheet of glass, some light will be reflected by the surface of the glass. However, much of the light will pass through the glass, because glass is transparent. ... This 'bending of a ray of light' when it passes from one substance into another substance is called refraction.
