Answer:
Power, P = 300 W
Explanation:
We have,
Force acting on the box to take it is 300 N
It is moved to a distance of 10 m in 10 seconds
It is required to find the power required to move the box. The rate at which work is done is called power required by an object. It can be given by the formula as follows :
![P=\dfrac{W}{t}\\\\P=\dfrac{Fd}{t}\\\\P=\dfrac{300\times 10}{10}\\\\P=300\ W](https://tex.z-dn.net/?f=P%3D%5Cdfrac%7BW%7D%7Bt%7D%5C%5C%5C%5CP%3D%5Cdfrac%7BFd%7D%7Bt%7D%5C%5C%5C%5CP%3D%5Cdfrac%7B300%5Ctimes%2010%7D%7B10%7D%5C%5C%5C%5CP%3D300%5C%20W)
So, the power required is 300 W.

ROASTING IS THE SKELETON EQUATION
Answer:
The pressure of the gas is 0.278 atm
Explanation:
Step 1: Data given
Number of moles of the ideal gas = 0.540 moles
Volume = 35.5 L
Temperature = 223 K
Step 2: Calculate the pressure of the gas
p*V = n*R*T
⇒with p = the pressure of the gas = TO BE DETERMINED
⇒with V= the volume of the gas = 35.5 L
⇒with n = the moles of the gas = 0.540 moles
⇒with R = the gas constant = 0.08206 L*atm/mol*K
⇒with T = the temperature of the gas = 223 K
p = n*R*T / V
p = 0.540 * 0.08206 * 223 / 35.5
p = 0.278 atm
The pressure of the gas is 0.278 atm
