The formula for calculating velocity of wave is expressed as
v = fλ
where
v = velocity of the wave
λ = wavelength
f = frequency of the wave
From the information given,
v = 340
f = 502
Substituting these values into the formula, we have
340 = 502λ
Dividing both sides of the equation by 502,
340/502 = 502λ/502
λ = 0.68 m
The wavelength is 0.68 m
Thermal energy is heat energy. Thermal means heat, and I bet you're really smart!

Below is the solution:
Output work = 108 J.
<span>Input work = 120 J </span>
<span>Efficiency = 108/120 = 9/10 = 90% </span>
<span>(Energy can be converted to heat in friction at the fulcrum, or useless potential energy distorting the crowbar)</span>
Answer:
The earth is tilted away from the sun more, and the angular perspective someone has on it is lower, which contributes to the cooler temperatures.
