wavelength x frequency = the speed of light
The force of gravity is much weaker than the strong nuclear force. But the strong nuclear force only acts over short distances, such as within the nuclues. The gravitational force can act over infinite distance.
Answer:
coal as a fuel source led to the invention of the printing press i think
Answer:
it is accelerating 14 m/s
Explanation:
Static friction is a force that keeps an object at rest. Static friction definition can be written as: The friction experienced when individuals try to move a stationary object on a surface, without actually triggering any relative motion between the body and the surface on which it is on
<h3>How can calculate the Fs by finding your normal force and multiplying it by your static friction force?</h3>
N = mg = (9.8)×(58) = 568.4N
Fs = NKs = (568.4)×(0.42) =238.7N
b) So this is an interesting question, she's going at a speed of 0.6 m/s. Kinetic friction is pushing her back so theres a negative force which is the force of kinetic friction right. So its NKf = (238.7)×(0.35) = 83.5N
