Explanation: A contact force is any force that requires contact to occur. Muscular force is force that results due to the action of muscles. It is a contact force, since there is a contact between the surfaces.

Explanation: The total distance covered by the sound from the point of generation to the reflecting surface and back should be at least 344 m/s (speed of sound) × 0.1 s = 34.4 m. Thus, for hearing distinct echoes, the minimum distance of the obstacle from the source of sound must be half of this disRead more
Explanation:
The total distance covered by the sound from the point of generation to the reflecting surface and back should be at least 344 m/s (speed of sound) × 0.1 s = 34.4 m. Thus, for hearing distinct echoes, the minimum distance of the obstacle from the source of sound must be half of this distance. I.e., 34.4/2 = 17.2 m.

Explanation:
RADAR – RAdio Detection And Ranging.
A radar system consists of a transmitter producing electromagnetic waves in the radio or microwaves domain, a transmitting antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a receiver and processor to determine properties of the objects.
Radar is an object-detection system that uses radio waves to determine the range, angle, or velocity of objects. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain.
Radio waves from the transmitter reflect off the object and return to the receiver, giving information about the object’s location and speed.

Explanation: Any of the basic mechanical devices for applying a force are called simple machines. There are 6 basic simple machines; the lever, the wheel and axle, the inclined plane, the wedge, the pulley, and the screw. Several of these simple machines are related to each other.

Explanation:
Force = Mass × Acceleration = m × a
Force has magnitude as well as direction. It is a vector quantity.
20 = 10 × a
a = 2 m/sec²

Explanation:
Zeeman Effect:- It is the name of the phenomena in physics and astronomy which involves the splitting of a spectral line into two or more components of slightly different frequencies when the light source is placed in a magnetic field.
It is named after the Dutch physicist Pieter Zeeman.
The effect is caused due to the distortion of the electron orbitals because of the magnetic field.
This effect is very useful n investigating the charge/mass ratio and magnetic moment of an electron.
Raman Effect:- It is nothing but the change in the wavelength of light that occurs whenever a light beam is deflected by molecules.
Alpenglow Effect:- It is an atmospheric optical phenomenon. It makes mountains appear to glow in a light pink or red hue after the Sun sets or just before it rises.
