The frequency heard by the moth is the frequency emitted by the bat by virtue of its speed; 38.0kHz. B) If the speed of the bat is increased, the frequency heard by the moth is higher.
<h3>What is the frequency heard by the moth?</h3>
It follows from the task content that the frequency of the emitted by the bat is heard by the moth and hence, the frequency heard by the moth is; 38kHz.
B) Since, the speed and frequency of sound waves are directly proportional, speed = wavelength × frequency; it therefore follows that when the speed of the bat is increased, the frequency heard by the moth is higher.

Answer:
85 K
Explanation:
T₀ = initial temperature of the gas = 77 K
T = final temperature of the gas = ?
n = number of moles of monoatomic gas = 1.00 mol
R = universal gas constant = 8.314
c = heat capacity at constant volume = (1.5) R = (1.5) (8.314) = 12.5
Q = Amount of heat absorbed = 100 J
Amount of heat absorbed is given as
Q = n c (T - T₀)
100 = (1) (12.5) (T - 77)
T = 85 K
In general the temperature increases with depth below the earths surface
Explanation:
Hey there!
Given that 4kg ball struck by 12 N force.
So, we need acceleration.
Force = Mass × Acceleration
And, so
Acceleration = Force / Mass.
Acceleration = 12/4
<u>Acceleration</u><u> </u><u>is</u><u> </u><u>equal</u><u> </u><u>to</u><u> </u><u>3m</u><u>/</u><u>s</u><u>²</u><u> </u><u>in</u><u> </u><u>SI</u><u> </u><u>units</u><u>.</u>
Hope it helps :)
