This is called the restoring force.
Venus is closer, relatively the same size as the earth and has an atmosphere
No, you wouldn't do any more work by going up the stairs twice as fast.
work done is equal to : F x D
time is not included, which mean you only done the work faster, but not doing any more work compared to the slower one
hope this helps
A.) We use the famous equation proposed by Albert Einstein written below:
E = Δmc²
where
E is the energy of the photon
Δm is the mass defect, or the difference of the mass before and after the reaction
c is the speed of light equal to 3×10⁸ m/s
Substituting the value:
E = (1.01m - m)*(3×10⁸ m/s) = 0.01mc² = 3×10⁶ Joules
b) The actual energy may be even greater than 3×10⁶ Joules because some of the energy may have been dissipated. Not all of the energy will be absorbed by the photon. Some energy would be dissipated to the surroundings.
Answer:
18.4 m/s
Explanation:
The gravitational force between the Death Star and the Millenium Falcon is equal to the centripetal force that keeps the Millenium Falcon in circular orbit:
where
is the gravitational constant
is the mass of the planet
is the mass of the Millennium Falcon
is the orbital velocity of the Millennium Falcon
is the radius of the Death Star
is the altitude of the Millennium Falcon above the planet's surface
Solving the equation for v, we find the orbital velocity:
