Answer:
The kinetic energy will have an increase as it falls.
Explanation:
The energy of a particle falling freely will be the sum of its kinetic energy and its potential energy.
When the pig is just dropped, the total enrgy will be only its potential energy. As it falls down its stored potetial energy will be converted into kineitic energy. Just before it touches the trampoline its total energy will be solely kinteic energy.
Thus, the kinetic energy will have an increase as it falls.
Answer:
When two magnets are brought together, the opposite poles will attract one another, but the like poles will repel one another. This is similar to electric charges. Like charges repel, and unlike charges attract.
Answer: A.). Be equal to the time the ball hits the group
Explanation:
Answer:
0.16Hz
Explanation:
wavelength (λ) = 125 meters
speed (V) = 20 m/s
frequency (F) = ?
Recall that frequency is the number of cycles the wave complete in one
second. And its value depends on the wavelength and speed of the wave.
So, apply the formula V = F λ
Make F the subject formula
F = V / λ
F = 20 m/s / 125 meters
F = 0.16 Hz
Answer:
x = 102.33 m
Explanation:
Given that,
Position where a forest ranger stands is 35 m above the ground. The angle of depression to the base of the fire is 20. We need to find how far from the tower is the fire.
Let the distance is x. We can find x using trigonometry as follows :
Hence, the fire is at a distance of 102.33 m from the fire.
