<h2>
Answer:It is not affected by the change in media.</h2>
Explanation:
Transverse waves are those waves where the medium particles vibrate perpendicular to the direction of propagation.
Transverse waves do not require any medium.
They travel with same speed in any medium.
Electromagnetic waves are transverse waves where the medium particles vibrate perpendicular to the direction of propagation.
So,their speed is same in any medium.
Answer:
The gravity of the Sun keeps the planets in their orbits. They stay in their orbits because there is no other force in the Solar System which can stop them.
Explanation:
Answer: The temperature of the air affects the speed of sound in the due to the fact that colder contains air molecules with low kinetic energy. For warm air the kinetic energy of the molecules is high causing them to move in rapid motion. Because of these vibrations and collisions sound waves moves in a faster rate.
Explanation:
Answer:
Diffraction: Wave Theory
Interference: Wave Theory
Reflection: both particles and wave theories
Refraction: both particles and wave theories
To solve this problem it is necessary to apply the trigonometric ratios of the given velocity components.
If we make a graph of the velocity vectors in their respective velocities according to the given description we will have something similar to the attached graph.
The angle could be obtained from the components of the opposite leg and the adjacent leg so that


The opposite leg value (y) is 40cm / s and the adjacent leg (x) is 30cm / s


Therefore the final direction that does the first ball is 36.87°
