Potential energy that depends on height is called
kakasveta [241]

Answer:

gravitational potential energy

Explanation:

a. You can rule out kinetic energy because it is a different type (the energy of motion).

<u>b. this is correct, because it is the energy that depends on an objects place on the gravitational field. As you can imagine, an object resting at a high place could be moved by gravity if it has the chance to fall.</u>

c. I am assuming you meant elastic, and that can be ruled out because while that is potential energy, it is dependent upon being stretched (for example a rubber band holds elastic energy when stretched).

d. mechanical energy is the sum of both kinetic and potential energy, and the question specifically asks about potential energy.

Will a block of material having a volume of 1.97 x 105 cm3 and weighing 1.59 kg float or sink when placed in water? Show calcula
Olenka [21]

Answer:

float

Explanation:

density= mass/ volume (kg/m^3)

1.59 kg/0.197 m^3

=8.07 kg/m^3

density of H2O= 1000 kg/m3

since density(block)<density(H2O), the block will float

(can also be done in g/cm^3)

1590 g/ (1.97*10^5 cm3)= 0.00807 g/cm^3 < 1 g/cm^3 (h2O)
