Sound and thermal/ heat energy.
Explanation:
Electric drill use electrical energy to convert it into kinetic, but there are some energy waste during the conversion in the form of sound and thermal caused by electric motor.
Answer:
If the kinetic energy increases, the potential energy decreases, and vice-versa.
Explanation:
The amount of change in kinetic energy is equal to the amount of change in potential energy.
In a transverse wave the particle displacement is perpendicular to the direction of wave propagation. The animation below shows a one-dimensional transverse plane wave propagating from left to right. The particles do not move along with the wave; they simply oscillate up and down about their individual equilibrium positions as the wave passes by. Pick a single particle and watch its motion.
The S waves (Secondary waves) in an earthquake are examples of Transverse waves. S waves propagate with a velocity slower than P waves, arriving several seconds later.

Answer:
Part a)
Part b)
Explanation:
Part a)
In order to have same range for same initial speed we can say
so after comparing above we will have
so we have
Part b)
Time of flight for the first ball is given as
Now for other angle of projection time is given as
So here the time lag between two is given as
Answer:
There you have it. The y-component of air resistance for the fired bullet still depends on the fired speed of the bullet (since it is proportional to v2). A fired bullet (with air resistance) does not hit the ground at the same time as a dropped bullet.
