Gravitational potential energy is

                       (mass) x (gravity) x (height) .

When you see this formula, you should be asking yourself:
"Self !  'Height' above WHAT ?

The answer to that question is:  It doesn't matter.  It can be the height
above anything, as long as you make very clear what the reference
(zero) level is, so that it doesn't change during the course of working
with the problem.

There is no particular level relative to which the gravitational potential
energy must always be measured.

In a large number of cases ... like when the problem involves something
going up and down hills, or roller coasters making loops, or soccer balls
or golf balls being launched ... the reference level for gravitational energy
is the ground, because it's THERE and it's convenient.

But if the action in the problem takes place in an office on the 80th floor
of the Aon building in Chicago, or down in a coal-mine shaft in Kentucky
where da sun don't shan, then the floor of the room you're in would be a
much wiser and more convenient level to adopt as the the zero-reference
level.

There's no law.

Answer:

SO4

Explanation:

I'm not sure if you're asking for more than one answer but S04 is one of them, you can search it up if you don't believe me

ion with the subscript of the atoms in a polyatomic ion. There is only ONE Cu and ONE S04, so get the charge for the Cu based on the S04. The formula is S04 , and there is only ONE S04 2, so Cu's charge here must be +2 for the compound to have an overall charge of zero. = copper (Il) ion S04 = sulfate ion then CuS04 = copper (Il) sulfate

Which of the following has both kinetic and potential energy?
zysi [14]
It should be A.
A ball bouncing is moving so if it’s moving that means it has kinetic energy. It also has potential energy because when it hits the floor it kind of stops so it has potential.

-Hope this helps.

1. explain why mid-sized cars and SUVs have different rollover fatality rates.
iris [78.8K]

Answer:

1.  They generally have poorer fuel efficiency and require more resources to manufacture than smaller vehicles, thus contributing more to climate change and environmental degradation. Their higher center of gravity increases their risk of rollovers.

2. Mid-sized cars and SUVs both have a fixed object fatality rate of 2.6/BVM. This is most likely because they have a similar mass and inertia. The force of the crash is likely to have about the same deceleration in both vehicles.
