KE= o.5 m times V squared
Answer:
sound intensity is explained by the following formula I= P/A where I= sound intensity(W/m²),P=power(W),A= area(m²) I hope this helps good luck!
Answer:
The coefficient of kinetic friction μ = 0.278
Explanation:
The frictional force on the crate is given by F = μN where μ = the coefficient of kinetic friction and N = normal force. The normal force equals the weight of the crate W = 180 N.
Since the kinetic friction F = 50 N, and the normal force which is the weight of the crate equals N = W = 180 N, the coefficient of kinetic friction μ is given by μ = F/N
= 50 N/180 N
= 0.278
So, the coefficient of kinetic friction μ = 0.278
Answer:
is the liberation of electrons from an electrode by virtue of its temperature
Explanation:
Given our understanding of the situation, for this vehicle with four wheels is traveling in a <u>linear path</u> through soft dirt, we would expect for<em><u> </u></em><em><u>only two wheels</u></em> to leave tire track impressions.
The vehicle has four wheels, and one might think initially that it makes sense for <u>all four wheels to create tire track impressions</u> on the dirt. This assessment is correct, all <u>four </u><u>tires </u><u>will create impressions</u>, However, <u><em>not all four </em></u><u><em>tires</em></u><u><em> will leave a said </em></u><u><em>impression</em></u>.
This is due to the fact that as the vehicle advances, the tires in the back <em>will erase the </em><em>impressions </em><em>left by the </em><em>front tires</em>. Therefore, <u>only </u><u>two </u><u>tire </u><u>track impressions </u><u>will be left.</u>
