To solve this problem it is necessary to apply to the concepts related to energy conservation. For this purpose we will consider potential energy and kinetic energy as the energies linked to the body. The final kinetic energy is null since everything is converted into potential energy, therefore
Potential Energy can be defined as,
Kinetic Energy can be defined as,
Now for Conservation of Energy,
Therefore the highets position the car reaches above the bottom of the hill is 40.02m
It depends on if it is a sound wave or light wave
Answer:
"When neutral objects are brought near the sphere, they are attracted to the sphere before they touch each other."
Explanation:
Charging by induction is said to occur when an uncharged object is brought near a charged body and it gets attracted towards it without even the two bodies touching.
The charged body polarizes the uncharged body. The charges shift to either sides and that causes the force of attraction between the two.
Suppose a negatively charged body is brought close to an uncharged body. The electrons of the body repel from the side near to the charged body and shift to the other end leaving behind positive ions.
The last line of the given paragraph indicates that charges can be moved by induction.
Firstly let us get the time down to minutes from hours. Then the calculation will become easy.
1 hour and 45 minutes = (60 + 45) minutes
= 105 minutes
So
The distance traveled by the car in 105 minutes = 98 miles
Then
The distance traveled by the car in 60 minutes = (98/105) * 60 miles
= 5880/105 miles
= 56 miles
So the average speed of the car as can be seen from the above deduction is 56 miles per hour.
