Answer:
Explanation:
Since X-rays are high (energy) frequency photons and radio waves are composed of low (energy) frequency photons, X-rays are more energetic and can do more harm to organic materials (such as cells).
Answer:

Explanation:
Given,
mass of the object,m = 0.30 Kg
initial speed, v_i = 3 m/s
time of collision = 0.20 s
final speed, v_f = -4 m/s
Impulse = change in momentum



Hence, impulse of the object is equal to

Answer:
waves
Explanation:
There are three major ways in which heat or thermal energy is transferred namely: conduction, convection and radiation. Please find the description of each below;
- Conduction is the method of heat transfer which involves a physical contact between the substances involved.
- Convection, on the contrary, occurs via a liquid medium
- RADIATION is a method of heat transfer which involves neither physical contact or liquid medium (matter) but occurs through WAVES e.g electromagnetic waves. For example, the sun transfers heat to the Earth via RADIATION.
