A brick is sitting motionless on top of a wall. What type of energy does it have?
A. kinetic energy
B. potential energy
C. electromagnetic energy
D. geothermal energy
there’s 5 different questions in total this is just the first question.
b. potential energy
d. after it goes downhill and begins to climb again
c. he can use a thermometer to measure the waters temperature
b. gas a has a greater kinetic energy
b. The molecules of water have gained kinetic energy and increased in volume
whats the answer....? lol
Alexiazator_ is correct
m g h = potential energy of mass m at height h above chosen 0 under gravitational acceleration g, about 9.81 m/s^2 on earth.
Well, we know that it isn't electromagnetic energy because a brick doesn't have anything to do with electric. So, we know C isn't the answer. It's not geothermal energy. An example of geothermal would be like lava or boiled water. So, we know its not D. So our choices are between A and B.
What do you think the answer is?
1. potential energy
2. after it goes downhill and begins to climb again
3. He can use a thermometer to measure the water's temperature.
4. Gas A has greater kinetic energy.
5. The molecules of water have gained kinetic energy and increased in volume.
To determine the type of energy a brick has when it is sitting motionless on top of a wall, we need to understand the different types of energy. Here are the choices given:
A. Kinetic energy: This type of energy is associated with the motion of an object. Since the brick is not moving, it does not have kinetic energy.
B. Potential energy: This type of energy is associated with the position or height of an object. When the brick is sitting on top of the wall, it has potential energy because it has the potential to fall due to gravity. Therefore, potential energy is the correct answer.
C. Electromagnetic energy: This type of energy is associated with light and electromagnetic waves. Since the question does not mention any interaction with light or electromagnetic waves, this is not the correct answer.
D. Geothermal energy: This type of energy is related to heat energy stored beneath the Earth's surface. Since the brick being motionless on top of a wall does not involve geothermal energy, this is not the correct answer.
In conclusion, the correct answer is B. potential energy
