Answer:
the heat always transfers from high temperature to low temperature body without aid of any external energy to this law the heat transfers from cup of coffee to the person body until both bodies reaches to the equilibrium state
Explanation:
the greater the <u>mass</u> of an object the more force is needed to cause acceleration
I literally looked everywhere for the answer, and I still found nothing. I hope you get it right. Sorry.
So the equation for angular velocity is
Omega = 2(3.14)/T
Where T is the total period in which the cylinder completes one revolution.
In order to find T, the tangential velocity is
V = 2(3.14)r/T
When calculated, I got V = 3.14
When you enter that into the angular velocity equation, you should get 2m/s
Answer:
0.655 m
13.468°C
Explanation:
v = Speed of sound at 20.0°C = 343 m/s (general value)
