A beaker is filled 60 cm high with this liquid. What is the total pressure at the bottom of the beaker? (1 atm =1.013 x 105 Pa)
Amiraneli [1.4K]

Answer:

Total pressure =1.01*10^5 Pa

Explanation:

given data:

atmospheric pressure = 1.013 *10^5 Pa\

height of water column = 60 cm

Total pressure will be sum of atmospheric pressure and pressure due to water column

P =  Atmospheric pressure + pressure due to water column

pressure due to water =\rho*g*h

\rho of water  = 1420 kg/m^{3}

height of water column = 60 cm =0.60 m

Total pressure =1.013*10^{5}Pa + 1420*9.81*.60

Total pressure  = 109649.6 Pa = 1.10*10^5 Pa

Total pressure =1.01*10^5 Pa

A car is raised on a lift at a service station (so it has some amount of gravitational potential energy relative to the ground).
kenny6666 [7]

Answer:Twice

Explanation:

It is given that car is raised on a lift with respect to ground.

Suppose car is raised by a height of h m from ground having mass m so gain in Potential Energy by car is

Gain in P.E._1=m\times g\times h

Now if it were raised twice as high,i.e. 2 h height from ground then gain in Gravitational Potential Energy

=m\times g\times 2h

P.E._2=2m\cdot g\cdot h

It is clear that P.E._2=2\cdot P.E._1

Thus in second case gain in Potential Energy is twice as compared to first case
