The answer is 20 meters would be the water depth started to feel bottom. This is half of the wavelength. The reason behind this is the wave travels half or the partial of the wavelength underneath the surface. For that reason that is where the wave would be starting to feel the ground.
It is A I have done this in my science.Try Quizlet for more info.<span />
Work done = fore × distance
wd= 47N ×o.25m
wd= 12.22Nm
A! Good luck on your test!
Answer:
The chemical reactions are depends up on the temperature. Temperature is a measure of motion of the particles, which increases by supplying thermal heat energy. According to the Kinetic molecular theory, if the reaction happens between two compounds, they collide with enough energy to overcome the activation of energy barrier.
The kinetic energy of the particles increases with increase in temperature. This results in collision being more energetic and therefore more likely to be able to overcome the activation barrier. The rate of chemical reactions increases with more collision of molecules.
<em>So, the temperature is the important parameter to increase the rate of reactions. </em>
