Answer:He lifts 2 meters
Explanation:We are trying to find the distance. The formula for distance is W/Force. 50 is our amount of work. 25N is how much force was used. Divide the work bye the force. 50/25=2M
Since the density of the substance is ρ (rho),
==> every cm³ of this substance has ρ grams of mass.
Then
==> V cm³ of it has ρV grams of mass. That's ' m '.
and
==> 3V cm³ of it has 3ρV grams of mass. That's ' <em>3m</em> '.
Use the formula dgh + p atm
d is density g is gravitational field strength h heigh or depth and p atm is atmospheric pressure
1000 x 10 x 20 + 100000 = 300000
almost 300,000 pascal
Answer:
Guessing you just need help with the definition but if it's the question I can still help you.
