Answer:
A . Are the masses repelling or attracting
answer:
<em><u>So, positive energy densities ("masses") attract each other by gravitational interaction. This is the general idea.</u></em>
<em><u>B</u></em>. What is the magnitude of the electrical force between the objects<em><u>?</u></em>
<em><u>answer</u></em><em><u>:</u></em>
<em><u> </u></em><em><u>The magnitude of the electrostatic force F between two point charges q1 and q2 is directly proportional to the product of the magnitudes of charges and inversely proportional to the square of the distance between them.</u></em>
C. What would the magnitude of the force be if one of the charges was 1/3 the amount?
answer:
<em><u>0.45</u></em>
D. ) What would the force be if the distance between the charges was only 1 meter (with the original charges)?
answer;
<em><u>Fmin=2.3×10^−28</u></em><em><u>N</u></em>
<em><u>E</u></em><em><u>:</u></em><em><u> </u></em>What would the force be if one of the charges was 1/3 the amount AND the distance was 1 meter?
answer;
<em><u>Electrostatic force is directly related to the charge of each object. So if the charge of one object is doubled, then the force will become two times greater.</u></em>

Answer:
The answer is below
Explanation:
a) Given that the modulus of elasticity (E) = 317 GPa, to find the modulus of elasticity (in GPa) for the nonporous material (
), we use the formula:
b) If the porosity P = 11.1%, then the modulus of elasticity is:
Answer:
D. gravitational potential energy
Explanation:
Well, we don't know if it's the CLOSEST one, but it's closer than the other ones on this print-out.
There are actually three clues to this in the seismograms:
1). The waves from the tremor reach the Wink station first ... the P wave gets there 50 seconds before Chicago and 3 whole minutes before Tampa.
2). They are stronger (greater amplitude) at Wink than at Chicago or Tampa.
3). The delay between the P wave and the S wave is the smallest at Wink. This delay between the two waves grows as the detector is farther from the quake.
m = mass of granite boulder = 20 g
c = specific heat of granite boulder = 0.79 J/gC
T₀ = initial temperature of granite boulder = 10 °C
T = final temperature of granite boulder = 29 °C
Q = heat gained by granite boulder as energy from the sun
heat gained by granite boulder is given as
Q = m c (T - T₀)
inserting the values
Q = (20) (0.79) (29 - 10)
Q = 300.2 J
