Answer:
the difference between a charged body is an body that has either a surplus or deficiency of electrons, and is negatively and positively charged respectively. And the difference between an uncharged body is that it’s a 'neutral' body that has an equal number of protons and electrons.
Explanation:
Answer;
-A wave with the longest wavelength.
Explanation;
-Diffraction is the apparent of wave through,around small obstacles and the spreading out of wave past small openings. When thinking of diffraction of a wave think of shining a flashlight around a corner. The light bends around the corner but there is a place where it is dark and the light does not hit. Diffraction of a wave is basically the wave bending around an object then dispersing out.
-The amount of diffraction (the sharpness of the bending) increases with increasing wavelength and decreases with decreasing wavelength. When the wavelength of the waves is smaller than the obstacle, no noticeable diffraction occurs.
Momentum before collision = momentum after collision
McVc=(Mc+Mb)V
1200*15.6=(1200+1500)*V
18720=2700*V
V=18720/2700
V=6.9m/s
