Gravitational potential energy (1) - masss (kg) x gravitational field strength (N/kg) x height (m) 1. Calculate the gravitational potential energy of the following masses on top of Trump tower which has a mass
of 202 m (g= 9.81 N/kg)
a) 100 kg
b) 90 kg
c) 45 kg
d) 58 kg
e) 1g
1) 1000 g
h) 1998
1) 1.5 kg
g) 100 g

Actually Welcome to the Concept of the Potential Energy.

Here lets calculate it one by one ;-

1.) P = mgh ==> 100*9.81*202===> 198162 Joules

2.) P = mgh ==> 90*9.81*202 ==> 178345.8 Joules

3.) P = mgh ===> 45*9.81*202 ===> 89172.9 Joules

4.) P = mgh ===> 58*9.81*202 ===> 114933.96 Joules

5.) P = mgh ===> 0.001*9.81*202 ===> 1.981 Joules

6.) P = mgh ===> 1.00*9.81*202 ===> 1981.62 Joules

7.) P = mgh ===> 1.998*9.81*202 ==> 3959.27 Joules

8.) P = mgh ===> 1.5*9.81*202 ===> 2971.43 Joules

9.) P = mgh ===> 0.1*9.81*202 ===> 198.162 Joules.

Above we calculated the potential energy for every mass given above.

the reason is because the moon has some form of gravity, and that gravity pulls the ocean tides.

im sorry i dont know
