Pauline the pigeon is perched at the top of St Paul’s Cathedral, a height of 111 m. Pauline has a mass of 0.9 kg and the gravitational field strength is 9.8 m/s2. Complete the symbol equation below to give the equation you would use to calculate Pauline’s gravitational potential energy.Ep = ?

A bird flies from the ground to a height of 200 m. If the bird has a mass of 1.5 kg, how much gravitational potential energy does it gain?A.550 JB.1960 JC.300 JD.2940 J

A 4 kg vase sits on a shelf at a height of 1.2 m. How much gravitational potential energy is added to the vase when it is lifted to a shelf of height 1.4 m?A.7.84 JB.47.0 JC.54.9 JD.31.2 J

A weightlifter lifts a 8080kgkg barbell off the floor and raises it to a final height of 2.12.1mm. Calculate how much gravitational potential energy the barbell had at the top of the lift. Use g=9.8g=9.8Nkg−1Nkg −1 and include units in your final answer. Round to 00 decimal places. ΔEp=m×g×ΔhΔE p​ =m×g×Δh

An object of mass 12 kg is at a certain height above the ground. If the gravitational potential energy of the object is 480 J, find the height at which the object is with respect to the ground. (g = 10 ms–2)

An 1kg object is dropped from a height of 50 meters. What is its gravitational potential energy just before hitting the ground? (Take g = 9.8 m/s²)*1 pointa) 490 Jb) 245 Jc) 4900 Jd) 2450 J
