Answer:
we have to make another question we maxed it out again lol
Explanation:
Answer:
a. yes
Explanation:
The initial speed of the circular saw is:


Deceleration rate needed to stop the circular saw is:


The number of turns associated with such deceleration rate is:



Since the measured number of revolutions is lesser than calculated number of revolution, the circular saw meets specifications.
Answer:
The wave function for a material particle is often called a matter wave. The relationship between momentum and wavelength for matter waves is given by p = h/λ, and the relationship energy and frequency is E = hf.
Explanation:
Answer: 4.27 *10^6 N/C
Explanation: In order to calculate the electric field along the axis of charged ring we have to use the following expression:
E=k*x/(a^2+x^2)^3/2 where a is the ring radius and x the distance to the point measured from the center of the ring.
Replacing the data we have:
E= (9* 10^9* 0.3* 50 * 10^-6)/(0.1^2+0.3^2)^3/2
then
E=4.27 * 10^6 N/C
