Abackpack has a mass of 8kg. it is lifted and given 54.9 j of gravitational potential energy. how high is it lifted? acceration due to gravity is g=9.8m/s2

The height of the bag pack is 0.7 m.

The gravitational potential energy is given by the formula

P=mgh

Now plugging the values in the above equation to calculate the height of the bag pack

54.9=8*9.81*h

h=0.7 m

Therefore the bag pack is lifted to the height of 0.7 m.

the answer for apex is the lowest

the earths atmosphere is made up of nitrogen and oxygen. solids can turn into gasses through a process called sublimation. sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.

hope this : d
