3 0

Answer:

55.80s

Explanation:

Power is calculated using the expression

Power = Work done/Time

Workdone= Force ×distance

Workdone = 794×22

Work done = 17468Joules

From the power formula

Time = Workdone/Power

Time = 17468/313

Time = 55.80seconds

The elevator takes 55.80seconds to life the Taylor

gas stored in a tank at 273 k has a pressure of 50kpa. what happens to the volume when the pressure is decrease due to the added
AfilCa [17]

I can't think of any way that pressure can be decreased due to added pressure.

Be that as it may, and it certainly still is ...

No matter what you do to the pressure or the temperature of
the gas in that tank, the volume doesn't change.  Any sample
of gas always expands to fill the container in which it's confined. 
Its volume doesn't change until you either transfer it to another
container with different volume, or else change the volume of
the container it's in.

Why does a properly adjusted head restraint help prevent head and neck injuries to occupants in rear-end collisions? Explain you
hammer [34]
When a car hits you in a rear end collision, the car initially has a momentum going in one direction. This causes your car to move in the same direction that car was moving even if you were at rest. So, for conservation of momentum, you initially have momentum going in the east direction for example, after the collision, you will have a change in momentum which causes you to have a velocity in the west direction. This is because you are initially at rest and then there is a sudden change in velocity so when you speed up, that momentum causes you to move backwards. If you don't have a properly adjusted neckrest you could may experience whiplash.
