Answer: The electrostatic force will be the same
Explanation:
According to Coulomb's Law, when two electrically charged bodies come closer, appears a force that attracts or repels them, depending on the sign of the charges of this two bodies or particles.
In this sense, this law states the following:
"The electrostatic force between two point charges and is proportional to the product of the charges and inversely proportional to the square of the distance that separates them, and has the direction of the line that joins them"
(1)
Being is a proportionality constant.
Now, if each and are increased by 6, and the distance between them as well, we will have the following:
(2)
(3)
Simplifying:
(4)
Comparing (1) with (4) we can see the electrostatic force is the same.
Answer: .0380575J
Explanation:
The coffee filter originally only had potential energy, which can be found by:
PE = m * g * h → PE = .0013 * 9.8 * 3 = .03822 J
*Note the mass must be in kg!!!
All of this energy should be converted to kinetic energy, but the air molecules take some of the energy; the energy they gain can be found by finding how much energy the filter has at the bottom of its fall, and subtracting this from the original energy to see how much was lost;
All of the energy at the bottom equals kinetic energy, which can be found by:
KE = 1/2 * m * v^2 → KE = 1/2 * .0013 * .5^2 = .0001625 J
Thus, the air gained .03822 - .0001625 = .0380575J :)
<span>Gravity is defined as the attraction between objects. All objects with mass<span> are affected by gravity. (Mass is what the matter is made of.) Gravity
acts like a magnet pulling objects together. The Earth has gravity.
Gravity holds everything close to this planet. Trees, water, animals,
buildings, and the air we breathe are all held here by gravity.</span></span>
<span>We need gravity for us to stick on the ground and not to float into the
air. It stops objects from falling off our planet earth.</span>
Answer:
mechanical thermal chemical
Explanation: because you use mechanical energy to turn it on
Answer:
<em>Height = 5.65 km</em>
Explanation:
is the circumference or we can say measures the boundary of hemisphere of friction-less ice that he is sitting on.
So, the height will be = 2 x 3.14 x (30)^2 = 5654.7 m = 5.65 km
