The capacitance is defined as the maximum charge stored in a capacitor, Q, divided by the voltage applied, V:
The capacitor is initially charged with the battery of 108 V, so the the initial charge on the capacitor can be found by re-arranging the previous formula:
Answer:
During its trajectory the cannon ball will have kinetic and potential energy
E = KE + PE
The maximum value of PE will occur when the cannon ball was fired straight up - for other trajectories PE will be less because of translational KE
So E = M g h = 1/2 M v^2 for maximum height
h = v^2 / (2 * g) = 400 / (2 * 9.8) = 20.4 m
There actually three assertions here: one in A and two more in B.
All three assertions, as well as the reasoning described in this mess, are all False.
The correct choice from the list is e), but that doesn't even describe the complete Falseness of this disaster.
Answer:
E)The gravitational force increases by a factor of 4.
Explanation:
Isaac Newton presented the law of Universal Gravitation in his book published in 1687, "Philosophiae Naturalis Principia Mathematica". According to this Newton's law, the more mass the objects possess, the greater the force of attraction, and the closer they are to each other, the greater that force will be.
All material particles and all bodies attract each other simply by having mass, in direct proportion to their masses.<u> Gravity has an infinite theoretical scope; but, the force is greater if the objects are close, and while they are moving away that force loses intensity in proportion to the square of the distance that separates the bodies</u>. For example, if one object moves away from another three times the distance, then the force of gravity is reduced to the ninth part or vice versa if the distance between objects decreases with a factor of 2, the gravitational force increases a factor of 4.
Newton's law of universal gravitation is expressed as follows
:
Fg = G * M1 * M2 / (r12)^2
Where:
Fg: gravitational force
G: it is the universal gravitation constant and is worth approximately 6,674 * 10 -11
M1 and M2: mass of objects
r12: distance between objects
