In most cases the temperature must increase for thermal expansion to occur. Most substances expand as temperature increases because the atoms or molecules vibrate faster as temperature increases and experience greater separation.
Answer:

at t = 0.001 we have

at t = 0.01

at t = infinity

Explanation:
As we know that they are in series so the voltage across all three will be sum of all individual voltages
so it is given as

now we will have

now we have

So we will have

at t = 0 we have
q = 0

also we know that
at t = 0 i = 0




so we have

at t = 0.001 we have

at t = 0.01

at t = infinity

Answer:
The number of complete vibration or wave made in
one second is called frequency.
Answer: The only advantage cutting crops with a sickle is that its very effective for cutting lodged crops.
L=G·d
L=600N·3m=1800J
P=L/Δt=1800J/4s=450W
