Answer:
50 kg
Explanation:
fnet=ma
600-200=m8
divide both side by 8 to make m the subject of the formula Thus m=50kg
Answer:
Explanation:
In the question given :
Pressure is constant
Therefore, Work done, 
Pressure, P=1.01 × 105 Pa.
Final volume, 
Initial volume, 
Therefore, W=8.58\times 10^{5}\ J.
Also, Heat Given, 
Also, according to First law of thermodynamics:
Hence, this is the required solution.
