The roof of an apartment building is 58 meters high. A water tank on the roof has a mass of 38,000 kilograms. What is the
potential energy of the water tank?
21,599,200
10,799,600
211,672,160
2,204,000
I think its A am I right?
Yes, you are correct. The potential energy of the water tank is 21,599,200 Joules.
Yes, you are correct. The potential energy of an object is given by the formula P.E. = mgh, where m is the mass of the object, g is the acceleration due to gravity (approximately 9.8 m/s^2), and h is the height of the object.
In this case, the mass of the water tank is given as 38,000 kilograms, the height of the apartment building is given as 58 meters, and the acceleration due to gravity is approximately 9.8 m/s^2.
Using the formula, we can calculate the potential energy:
P.E. = (38,000 kg) x (9.8 m/s^2) x (58 m)
= 21,599,200 joules
So, the potential energy of the water tank is 21,599,200 joules. Therefore, option A is correct.
To calculate the potential energy of an object, you can use the formula:
Potential Energy = Mass x Gravity x Height
In this case, the mass of the water tank is 38,000 kg, the height is 58 meters, and the acceleration due to gravity is approximately 9.8 meters per second squared.
So, to find the potential energy, you can calculate:
Potential Energy = 38,000 kg x 9.8 m/s^2 x 58 m
Solving this equation gives the potential energy as approximately 21,599,200 Joules.
Therefore, your answer is correct. Option A, 21,599,200, is the potential energy of the water tank.
Well, you're not exactly right, but you're really close! The correct answer is actually B. 10,799,600.
Why did the water tank go on a diet? It wanted to decrease its potential energy by shedding some weight!
