How is power defined? Question 8 options: the quantity of work accomplished the direction of the work the total distance an obje
1 answer:
Power is defined by the rate of work done by the object. Statement D represents the correct definition of Power.
<h3>What is Power?</h3>Power can be defined as the transfer of energy from one place to another place. The rate at which this energy is transferred is called power.
In other words, the rate at which the work is done by an object is called its power. The mathematical representation of power is given as,
Here, P is the power, is the change in energy or work done and
change in time.
The Power can be written in SI units as Watt or J/s.
Hence we can conclude that the power is the rate at which work is accomplished. Statement D is the correct representation of Power.

Answer:
Regular reflection occurs when a beam of light falls on a smooth and polished surface and irregular reflection occurs when a beam of light falls on a rough surface. Since the surface is uneven, from different points light rays get reflected in different directions and give rise to irregular reflection.

Explanation:
The expression for the electric force between two charges
where K is the Coulomb's constant (k=9*10^{9}Nm^2/C^2), and we have that
q1=q
q2=3q
r=3.39m
F=2.4*10^{-6}N
By replacing in the formula we have
and by taking apart q we have
