If , then
If , then
so,
No, Joe's value does not agree with the accepted value of 25.9 seconds. This shows a lots of errors.
The energy stored in the capacitor decreases to one-half (½) of its initial value when the distance between the plates is then reduced to d/2.
<h3>The energy stored in a capacitor.</h3>
Mathematically, the energy stored in a capacitor can be calculated by using this formula:
U = ½CV² or U = q²/2C
<u>Where:</u>
- V is the potential difference.
Thus, we can logically deduce that the energy stored in the capacitor decreases to one-half (½) of its initial value when the distance between the parallel plate capacitors is reduced to d/2.

Answer:
The magnitude of the gravitational force acting on the lander on the surface of Mars is 512.46 N.
Explanation:
The Universal law of gravity is define as:
(1)
Where F is the gravitational force, G is gravitational constant, M is the mass of Mars, m is the mass of the lander and R is the radius of Mars.
Before replacing the values in equation 1 it is necessary to express the radius of mars in terms of meters:
R = ⇒ R =
Finally, equation 1 can be used:
Hence, the magnitude of the gravitational force acting on the lander on the surface of Mars is 512.46 N.
1 meter = 1e9 nm
To get meters, divide nanometers by 1e9:
9.95nm / 1x10^9 = 9.95x10^-9 meters
Answer: 9.95e-9 meters
