Answer:

Its composition and structure

Explanation:

The potential energy possessed by a molecule depends on its composition and structure. Its composition determines the type of intramolecular bonds present in the molecule and its structure determines the strength of the intramolecular bonds. Let's look at the example of the water molecule. It consists of two hydrogen atoms and one oxygen atom. The intramolecular bonds present here is the covalent O-H bond and since it has two O-H bonds in a molecule, and is V-shaped. These two properties determine the magnitude of the potential energy of the molecule.

The percentage of incident light radiation reflected back to space is termed albedo. True or false?

liubo4ka [24]

Answer:True

Explanation:

Albedo is a unit-less, non-dimensional quantity that shows how well a surface reflects solar energy. The value of albedo can vary from 0 to 1, 0 being the black and 1 refers to a white surface. Zero means Surface is a perfect absorber i.e. it absorbs all the incoming rays incidents on it. Albedo 1 means the surface is a perfect reflector.

Albedo usually applies for visible light, even though it may involve some of the infrared regions of the electromagnetic spectrum. The average albedo associated with earth surface is 30%

What force is required to move an object 8 m using 24 j of work?

Anna35 [415]

Answer:

Explanation:

Workdone = F x d

F = force

d = distance 8m

Workdone = 24J

24 = F x 8

Divide both sides by 8

24/8 = F x 8/8

3 = F

F = 3N

[Assume g = 10m/s?] If a girl is running along a straight road with a uniform velocity 1.5 m/s, find her acceleration. (Ans: 0)

DerKrebs [107]

Answer:

Her acceleration is 0 m/s²

Explanation:

We note that the motion of the girl is on a straight road, therefore;

The vertical acceleration (e.g. due to gravity, <em>g)</em> on the horizontal motion = 0

The horizontal acceleration, a = (Change in velocity, Δv)/(Change in time, Δt)

For uniform velocity, the change in velocity, Δv = 0

Therefore, fore any change in time, Δt, we have;

a = Δv/Δt

Her acceleration, a = 0/Δt = 0

Her acceleration, a = 0 m/s²
