He should confront her about it and if after that point she continues report it to the chess team
Heat required to raise the temperature of mercury is given as

here given that
m = 56 g
s = specific heat capacity of mercury = 0.140 J/g C

now here we have


so it required 2265.76 J of heat
Answer:
The angular velocity is
Explanation:
Generally the acceleration experienced by the propeller blade's is broken down into
The Radial acceleration which is mathematically represented as

And the Tangential acceleration which is mathematically represented as

The net acceleration is evaluated as

Now since angular speed varies directly with angular acceleration so when acceleration is maximum the angular velocity is maximum also and this point if the propeller blade's tip exceeds it the blade would fracture
So at maximum angular acceleration we a have
