Answer:
A fossil fuel power station is a thermal power station which burns a fossil fuel, such as coal or natural gas, to produce electricity. Fossil fuel power stations have machinery to convert the heat energy of combustion into mechanical energy, which then operates an electrical generator.

Answer:
8.87 m/s^2
Is the same for both planets
Explanation:
Hello!
The surface gravity can be calculated from Newton's Law of Gravitation and Newton's Second Law :
ma = F =G Mm/r^2
Solving for a:
a = G M/r^2
And the surface graity g = a(R), that is, the surface gravity is equal to the acceleration evaluated at the radius of the planet:
g = G M/R^2
Since G is a constant, we need to evaluate M/R^2 for both to know in which planet the surface gravity is the geratest:
M_u/R_u^2 = 1.323 x 10^11 kg/m^2
M_v/R_v^2 = 1.323 x 10^11 kg/m^2
It turns out that the surface gravity in both planets is the same! which is:
g = G M_u/R_u^2
= ( 6.67408 × 10-11 m^3 / (kg s^2) ) *( 1.323 x 10^11 kg/m^2)
= 8.87 m/s^2
*as you can check on google*
You would feel the same weigth in both planets, however you wil feel lighter in these planets than in earth.
B because there is no energy emitted
(5 mi/hr) x (1hr/60min) x (10min) = 5 x 10 / 60 = <em>5/6 mile</em>
(5/6 mile) x (1,760 yd/mile) = <em>1,466 and 2/3 yards</em>
