Answer:
Distance between two point charges, r = 0.336 meters
Explanation:
Given that,
Charge 1, 
Charge 2, 
Electric potential energy, U = -0.5 J
The electric potential energy at a point r is given by :
r = 0.336 meters
So, the distance between two point charges is 0.336 meters. Hence, this is the required solution.
P=F/A
Force= P * A = (2000 x 3) N = 6000N
I think the airplan flies in same speed 400
Answer:
"we both attract each other with the same force but we know that attraction between two bodies depends upon their mass, greater the mass of two bodies is the force of attraction between them"(got this off the internet).
1) Inversely
2) increases
3) Boyle's
4) mass
5) Kelvin
6) Charles's
7) Gay-Lussac's
8) directly
9) combined
10) the amount
<span>The pressure and volume of a fixed mass of gas are inversely related. If one decreases, the other increases. This relationship is known as Boyle's law. The volume of a fixed mass of a gas is directly proportional to its kelvin temperature. This relationship is known as Charles's law. Gay-Lussac's law states that the pressure of a gas is directly proportional to the kelvin temperature if the volume remains constant. These three separate gas laws can be written as a single expression called the combined gas law. It can be used in situations in which only the amount of gas is constant. </span>
