The bowling ball have more gravitational potential energy as it sit on top of the building
<u>Explanation:</u>
The energy that is possessed by an object due to the position of that object in the field of gravity is called Gravitational potential energy . The object that is present in the place that is very closer to the Earth's surface has a constant gravitational potential energy. When an object is at certain height there is a necessity of force for lifting that object form that height.
This is applies to the gravitational potential energy also.When two objects are placed at different heights, the object that is placed at the greater height will have more potential energy. This is because, the force necessary to take the object from greater height will be more.
Answer:
Number of neutrons: 44
Number of protons: 34
Number of electrons: 36
Explanation:
The atomic number of Se (Selenium) is 34
Mass number is 78
Number of neutrons = mass number - atomic number = 78 - 34 = 44
Number of protons is the same as the atomic number
Number of protons = 34
Selenium ion has a charge of -2. This means it accepts two more electrons
Number of electrons = atomic number + 2 = 34 + 2 = 36
Ultraviolet rays has the most energy

Answer: 1.14 M
Explanation:
500 mL is equal to 0.5 L.
So, the molarity is (0.570)/(0.5) = 1.14 M
