Answer:
37.5%
Explanation:
We define first our values, that are,
We can now calculate the net power output, that is
Thermal efficiency is given by
He should choose the room that’s 15 F.
-5 C = 23 F
Meaning that 15 F is below -5 C and 25 F is not.
Answer:
449.824 kg
Explanation:
F = Gm₁m₂/r²
Above equation can be used to find the gravitational force between two objects.
Here F is the Gravitational force. m₁ , m₂ are the masses of the objects and r is the distance between the objects. Let's take m₁ as the mass of the moon. Then m₂ is the mass of the satellite.
We are given that F = 324 N , m₁ = 7.3 * 10²²kg and r = 2.6 * 10 ⁶m.
324 = 6.67×10⁻¹¹ × m₁ × 7.3×10²² / (2.6 × 10⁶)²
m₁ = 449.824 kg
Answer:Same
Explanation:
Gravitational Potential energy is the function of height i.e. it is proportional to the height gained by an object or in other words work done against gravity is also gravitational Potential energy
For the same mass, if both attained the same height then gravitational Potential energy of both the friends is equal as it does not depend upon the path taken by the person.
I think most likely the answer is the first one. meeting other students. if not then maybe the second one, highly motivated.
