The seven types of waves are radio waves, microwaves, infrared, visible, ultraviolet rays, x-rays and gamma rays.
The electromagnetic spectrum is a broad spectrum consisting of various waves. It contains very long radio waves to very short gamma rays. However, the human eye can detect only a small portion of this spectrum called as visible light.
The other waves that are invisible to the eye have their applications in various fields.
For example, radio waves have the longest waves on the spectrum and are said to have lowest energy. An MRI machine uses these waves to see tissues and bones up close.

Answer:
V = 27.46 m/s
Explanation:
given,
mass of the deer(m) = 135 Kg
speed of the deer (u) = 10.5 m/s
assuming,
mass of the car(M) = 900 Kg
initial velocity of car (v) = 30 m/s
using conservation of momentum
m u + M v = (M + m )V
V is the velocity of the car as deer is on the car
135 x 10.5 + 900 x 30 = (900 + 135 ) V
28417.5 = 1035 V
V = 27.46 m/s
so, the velocity of car is equal to V = 27.46 m/s
When a new path of lesser resistance is made for an existing circuit a(n) short circuit occurs.

What is short circuit?</h3>
An electrical circuit short circuit is when two nodes that are supposed to be connected at different voltages make an improper connection. This leads to an electric current that can damage circuits, cause overheating, fire, or explosions, and is only constrained by the network's remaining nodes' equivalent Thevenin resistance. While short circuits are typically the result of a failure, they can occasionally be brought on purpose, such as when voltage-sensing crowbar circuit protectors are being installed.
An electrical connection that requires two nodes to have the same voltage is known as a short circuit in circuit analysis. Since there is no resistance and hence no voltage drop across the link in a "perfect" short circuit, there is no short circuit.

His average speed is (35m/45s) = 7/9 meters per second.
His average velocity is (30m W + 5m E) / (45s) = 25 m/s West .
Rutherford's nuclear model stated that a cloud of negative electrons surround the nucleus however scientists realized that electrons in a cloud around the nucleus of an atom would be attracted to the nucleus, causing the atom to collapse. Thus Bohr's model proposed that electrons were contained in shells and they orbit the nucleus at fixed distances.
