The correct answer is
<span>B) UV waves are higher frequency and carry more energy.
In fact, UV waves have higher frequency than visible light. For comparison, visible light has frequency in the range 430-770 THz (</span>

)<span>, while ultraviolets (UV) have frequency higher than these values (at the order of 1 PHz, </span>

).
The energy of electromagnetic radiation is proportional to its frequency, according to the equation

where h is the Planck constant and f is the frequency. We see that the higher the frequency, the greater the energy, so UV waves carry more energy than visible light.
Answer:
Correct answer: p₂ : p₁ = 1 : 3
Explanation:
A process that occurs at a constant temperature is called an isothermal process and the formula that applies to this process is:
p · V = const where p is pressure and V is volume
Given : V₂ = 3 V₁
p₁ V₁ = p₂ V₂ ⇒ p₂ / p₁ = V₁ / V₂ ⇒ p₂ / p₁ = V₁ / 3 V₁ ⇒ p₂ / p₁ = 1 / 3
p₂ : p₁ = 1 : 3
which means that when the volume is increased three times the pressure is reduced three times

Answer:
radiation, then convection
Windmills run on the principle of mechanical energy and work. Moving air (wind) possesses some amount of energy in the form of kinetic energy (due to motion). This energy gives the air the ability to do work on the blades of the fan.
Answer:

Explanation:
Force on a current carrying rod due to magnetic field is given as

here we know that
current in the rod


now magnetic force is balanced by the weight of the rod
so we will have
