8 wave units I guess I tried it should be the answer though
Number three
They contain protons (positive), neutrons (negative), electrons (neutral) and all are in a nucleus which is part of an atom
When the cannonball is shot upwards, kinetic energy converts to gravitational potential energy (GPE).
As the ball rises, speed decreases and height increases.
So when the cannonball has reached its maximum height, all of the Kinetic energy has transferred into gravitational potential energy.
(Because at the max height, the cannonball for a brief moment has no velocity, and thus no kinetic energy)
So the GPE is 48279 Joules at it's maximum height.
Answer:
Explanation:
As the current carrying wire carries current in south to north direction, the direction of magnetic field is given by the Right hand thumb rule which is in anticlockwise direction so the magnetic compass deflects towards west.
Explanation:
Because they change the direction of force and multiply the effort.
They increase the rate of doing work.
So, MA of first class lever can be one or greater than one or less than one
