Answer:
See below
Explanation:
The work done equals the increase in Potential Energy
PE = mgh
= 150 * 9.81 * 1 = <u>1471.5 j</u>
3 sets of 10 is 30 times this = <u>44145 j</u>
Answer:
3 micro coulombs = 3 * 10E-6 coulombs charge of aluminum
13 * 10E15 * 1.6 * 10E-19 = 2.08 E-3 Coulombs - charge of atoms in Al
3 * 10E-6 / 2.08 * E-3 = 1.44 * E-3 = .00144 = .144 %
.00144 of the original electrons would have to be lost
The Joule is a unit of energy, not Force
Answer:
.
Explanation:
Intensity 
of the electromagnetic radiation is given by
where 
is the distance from the EM source (the center of the sun, in our case), and 
is the power output of the sun and it has the value
Since the radius of the sun in meters is 
, the intensity of the electromagnetic radiation at the surface of the sun is
The intensity of the electromagnetic radiation at the surface of the sun is .
