Answer: gravitational potential energy is converted into kinetic energy
Explanation:
When the diver stands on the platform, at 20 m above the surface of the water, he has some gravitational potential energy, which is given by
where m is the man's mass, g is the gravitational acceleration and h is the height above the water. As he jumps, the gravitational potential energy starts decreasing, because its height h above the water decreases, and he acquires kinetic energy, which is given by
where v is the speed of the diver, which is increasing. When he touches the water, all the initial gravitational potential energy has been converted into kinetic energy.
Answer:
Explanation:
v = Velocity of the elevator = 3.1 m/s
= Angle of the slope = 
Vertical component is given by
The vertical component of the velocity is .
Horizontal component is given by
The horizontal component of the velocity is .
Answer:
cross at many points
Explanation:
According to the diagram it does not shows the real electric field as the electric field does not intersect with each other but according to the given diagram many lines are intersected with each other
So the correct option is C as it would be crossed at many points
Hence, the same would be relevant
Your list that you call "the following properties" is awfully short. / / / The displayed value tells you the car's speed relative to the pavement. (NOT its velocity.)
This describes a physical change. The glass shattering changes its physical shape and appearance only, as it retains its chemical composition.
