Answer:
kinetic energy
The average kinetic energy of water particles. Explanation: As it mentioned Temperature 45°, this clearly specify we are talking about kinetic energy of water particles, as temperature is nothing but the average of kinetic energy of particles randomly moving in water.
Answer:
Part A 2.88 A, PART B 28.82 mA PART C 0.288 mA
Explanation:
We have given angular frequency
Voltage source has an amplitude of 24.5 V, So V= 24.5 volt
Part A
We have given inductance
So inductive reactance
So current
Part B
We have given inductance
So inductive reactance
So current
Part C
We have given inductance
So inductive reactance
So current
If the cliff is 850m away, the sound travelled there and back which is 850m * 2 = 1700m
The sound took 5 seconds to travel 1700m, so it's moving at 1700m/5s = 340 m/s
