Answer: Geothermal energy is produced by the heat of Earth's molten interior. This energy is harnessed to generate electricity when water is injected deep underground and returns as steam (or hot water, which is later converted to steam) to drive a turbine on an electric power generator.
Explanation: Hope this helps!
Answer:
False
Explanation:
Potential energy is stored energy, so it is not in motion. Kinetic energy is the energy in motion.
<u>Answer</u>
224 Km
4 Km
<u>Explanation</u>
<u>Part 1</u>
The plane flies 100 Km north and then 200 Km east. This makes a 90° turn. To get the distance taken by the plane we get the hypotenuse.
c² = a² + b²
c² = 100² + 200²
= 50,000
c = √50,000
= 223.606 Km
The answer to the nearest whole number is 224 Km
<u>Part 2</u>
If the runner run 15 Km north then 11 Km south, the resultant distance would be,
15 - 11 = 4 Km
Answer:
0.25m
Explanation:
Using the expression that relates the angular velocity(w) and the linear velocity (v).
v= wr where;
w is the angular speed= 128rad/s
v is the linear speed = 32m/s
r is the radius
r = v/w
r = 32/128
r = 0.25m
The radius of the blade is 0.25m
Answer:
A time that is less than half an hour
Explanation:
it says velocity is positive so it would yield to a negative acceleration
