Answer:
even if it all could be used, it wouldn't be enough
Explanation:
The land area of the US is about 5.45% of the world's area, so the amount of released heat over the area of the US is on the order of 2.4 Tw. Current technology for converting geothermal energy to electricity is about 12% efficient, so the available energy might amount to 0.29 Tw if it could all be captured.
Energy consumption in the US in 2019 was on the order of 0.46 Tw. This suggests that even if <em>all</em> of the thermal energy radiated by the Earth from the US could be turned to useful forms of energy, it would meet only about 60% of the US need for energy.
Answer:
beat frequency = 13.87 Hz
Explanation:
given data
lengths l = 2.00 m
linear mass density μ = 0.0065 kg/m
String A is under a tension T1 = 120.00 N
String B is under a tension T2 = 130.00 N
n = 10 mode
to find out
beat frequency
solution
we know here that length L is
L = n × 
........1
so λ = 
and velocity is express as
V = 
.................2
so
frequency for string A = f1 = 
f1 = 
f1 = 
and
f2 = 
so
beat frequency is = f2 - f1
put here value
beat frequency = 
- 
beat frequency = 13.87 Hz
A hammer pounding a nail into a board is an example of Newton’s Third law.
Newton’s third law states that for every action there is an equal and opposite reaction. Meaning, when you hit the hammer on the board the same amount of energy that is going into the board, is going into the hammer. Causing the hammer to bounce off the board.
Hope this helps!
Answer: Earth exerts a gravitational force on the sun and the sun exerts a gravitational force on Earth
Its not very strong but strong enough to create tides. Compare the gravitational force the sun exerts on earth to the gravitational force earth exerts on the sun. ... Both because they both exert a force on each other the difference is the object with the greater mass being earth will exert a greater force.
Explanation:
Answer: The answer is obviously True!!!!
Explanation: The force of gravity depends directly upon the masses of the two objects, and inversely on the square of the distance between them. This means that the force of gravity increases with mass, but decreases with increasing distance between objects. ... However, the exponent on the mass terms is one.
