Answer: D
Explanation:
First, we know that the acceleration is defined as the ratio of change of the velocity.
This means that, if we have a change in the velocity, then we also have acceleration.
And by Newton's second law we know that:
F = m*a
Force equals mass times acceleration.
So if we have acceleration different than zero, then we should also have force different than zero.
So we must have a nonzero net force acting on it.
The correct option is D
The answer is referred pain.
Referred pain is the slow pain that is origination from an internal organ is often perceived as coming from an area of the body totally unrelated to the source.
Pain is distressing feeling. When any stimuli damages, we feel a pain such as when finger burns or toe is stabbed etc.
Answer:
diffracted into semicircular waves. constructive interference occurs where the waves are crest to crest or trough to trough, destructive interference occurs where they are crest to trough. The light that falls on the screen produces bands of light and dark fringes on the screen as a result of these constructive and destructive interferences. This is called the young's slit experiment.
Answer:
Subcategories: Ice field
Explanation:
Glacier ice is blue because the red (long wavelengths) part of white light is absorbed by ice and the blue (short wavelengths) light is transmitted and scattered. The longer the path light travels in ice, the more blue it appears.
To convert from newtons to kg in earth gravity, simply divide by 10 (or 9.8 if being specific). 645N = ~64.5kg
