How can a simple machine make work easier Without changing the about if work that's being done

1 answer:

5 0

A simple machine can reduce the amount of FORCE required to accomplish
a mechanical result, and that's how we decide how easy something is.

Of course, when the simple machine decreases the required FORCE, it
INcreases the distance through which the force must act. But we don't
usually care about the distance, only the force.

A sample of nitrogen gas has a volume of 5.0 ml at a pressure of 1.50 atm. what is the pressure exerted by the gas if the volume

A sample of nitrogen gas has a volume of 5.0 ml at a pressure of 1.50 atm. what is the pressure exerted by the gas if the volume increases to 30.0 ml, at constant temperature is 0.25atm.

On constant temperature, the pressure and volume relation become constant before and after the change in quantitities have occurred.

According to Boyle's Law,

P₁V₁ = P₂V₂

where, P₁ is pressure exerted by the gas initially

V₁ is the volume of gas initially

P₂ is pressure exerted by the gas finally

V₂ is the volume of gas finally

Given,

P₁ = 1.5 atm

V₁ = 5 ml

V₂ = 30 ml

P₂ =?

On substituting the given values in the above equation:

P₁V₁ = P₂V₂

1.5 atm × 5 ml = P₂ × 30 ml

P₂ = 0.25 atm

Hence, pressure exerted by the gas is 0.25atm.

it takes 29.5 minutes to walk with an average velocity of 1.2 m/s to the north from the bus stop to the museum entrance what is

olasank [31]

Displacement is distance moved,so if you have your velocity in m/s you need your total time in seconds and multiply the two to get displacement so at 1.2m/s travelling (9.5*60(60seconds in a minute)=570 seconds is 570*1.2=684
