Answer:

Explanation:
Given:
Final force between them=17(initial force between them)
initial separation between them 
Final separation between them 
Let Q and q be the charges on them then

Answer:

Explanation:
To answer the question, we just need to consider the motion along the horizontal direction.
The component of the initial velocity of the ice skater along the x-direction is:

where u = 2.25 m/s is the initial velocity and
is the angle.
The component of the final velocity of the ice skater along the x-direction is

where u = 4.65 m/s is the final velocity and
is the angle.
The acceleration along the x-direction is given by

where
t = 120 s is the time
Substituting,

Answer: Boyle’s law
Explanation:
Boyle's Law: This law states that pressure is inversely proportional to the volume of the gas at constant temperature and number of moles.
(At constant temperature and number of moles)
As pressure is decreased to half, the volume is increased to doubled.
Charles' Law: This law states that volume is directly proportional to the temperature of the gas at constant pressure and number of moles.
(At constant pressure and number of moles)
Gay-Lussac's Law: This law states that pressure is directly proportional to the temperature of the gas at constant volume and number of moles.
(At constant volume and number of moles)
Combined gas Law: combining the three laws:
Answer:
106417026.88435 m
Explanation:
T = Time period of the satellite = 4 days
m = Mass of the Earth = 5.972 × 10²⁴ kg
G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²
Time period is given by

The radius of the satellite's orbit is 106417026.88435 m
The naturally occurring radioisotope which is used as the fuel for a nuclear reactor is the Uranium-235. It has been said that one kilogram of Uranium-235 can theoretically male about 20 terajoules of energy when used as a fuel for power plants.
