A full 10,000-gallon water tank will be emptied using two pumps. Pump A working by itself is used to drain 30 percent of the tank total capacity, at which point Pump B is added to the job. If the entire job of emptying the tank takes 50 hours, and Pump A works at a rate of 100 gallons per hour, what is Pump B's rate, in gallons per hour?

the moon affects the earth gravitation ally, causing certain motions of that body and also producing tides in its ocean and atmosphere. the tidal wave in our atmosphere is, however, far too minute to be an effective cause in any known meteorological phenomenon.

explanation:

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
