Answer:
I₁ =1250 kg.m²
Explanation:
Given that
Angular speed of Merry ,ω₁= 0.2 rad/s
Angular speed of technician ,ω₂= 0.04 rad/s
Moment of the inertia of the technician ,I₂= 5000 kg.m²
Lets assume that
Moment of the inertia of merry with respected to the ground=I₁
There is no any external torque ,that is why angular momentum of the system will be conserve.
Now by conserving angular momentum
I₁ ω₁=(I₁+I₂)ω₂
I₁ x 0.2 = (I₁ +5000 ) x 0.04
I₁ (0.2-0.04) = 5000 x 0.04
I₁ =1250 kg.m²
Answer:
(a). The initial pressure is
(b). The final pressure is
Explanation:
Given that,
Number of moles = 7
Temperature = 475 K
Initial volume = 0.50 m³
Expanded volume = 1.50 m³
We need to calculate the initial pressure
Using formula of pressure
Put the value into the formula
We need to calculate the final pressure
Using formula of pressure
After expansion,
Put the value into the formula
For thermal process,
Hence, (a). The initial pressure is
(b). The final pressure is
