Answer:
C is the right answer.
Body massager uses electrical energy to move back and forth. In this sense, a motor is being used for the operation
Answer:
Explanation:
The rotated angle is given by:
Since this is a quadratic equation it can be solved using:
Rewriting our equation:
Since 
we discard the negative solution.
Answer:
i think it would be which angle converts the most potential energy to into kinetic energy of the turbine
Explanation: because the windmill makes kinetic energy and converts it into mechanical power. then a generator takes the mechanical power and makes it into electricity
<u>Answer:</u>
<em>The moon doesn’t change shape on its own.</em>
<u>Explanation:</u>
Shapes of moon that we observe is based on the different perspectives of view from the earth and position of moon with respect to the sun. The changes arise due to the rotation of earth on its own axis as well as the revolution of moon on its orbit. The moon doesn’t have any light of its own.
It just reflects off the light from the sun. Due to tidal locking phenomenon one face of the moon permanently faces the sun. Because of the changes in position of moon with respect to the sun the moon is lighted up variably giving rise to various phases like new moon, full moon, crescent etc.
Answer:
Place some smooth tiles under the dresser
Smooth surfaces, like smooth tile, are easy to slide over. They create very little friction. Rough surfaces like carpet create much more friction.
remove the drawers from the dresser
Weight affects friction in that friction is directly proportional to the weight of the load one is moving. So reduce the weight, reduce the friction.
Explanation:
Speed does not impact friction, so moving the dresser slower won't help. Wind has nothing to do with the scenario, so that's not a correct option.
