How do the mass and height of an object affect the gravitational potential energy?

Chemistry
1 answer:
marin [14]3 years ago
5 0

Answer:

B. mass and height have the same effect on gravitational potential energy.

Explanation:

Both mass and height have the same effect on the gravitational potential energy of body.

Gravitational potential energy is the energy of a body due to that of another body. It usually the energy at rest in a body.

It is mathematically expressed as;

 G.P.E  = m x g x h

m is the mass

g is the acceleration due to gravity

h is the height

We see that both the height and mass are directly proportional to the gravitational potential energy and as such, they have the same effect.

What element has 80 protons, 81 neutrons, 79 electrons?
Mariana [72]

Answer:

The element will be ^{161}_{80}X

Explanation:

Given that,

Number of proton = 80

Number of neutron = 81

Number of electron = 79

We know that,

The atomic number is equal to the number of proton.

So, the atomic number is 80.

According to atomic number,

The element will be mercury.

We need to calculate the atomic mass

Using formula of atomic mass

atomic\ mass=atomic\ number+number\ of\ neutron

Put the value into the formula

atomic\ mass=80+81

atomic\ mass=161

We need to find the element

Using atomic mass and atomic number

atomic\ mass\ number A=161

atomic\ number Z=80

So, the element will be

^{A}_{Z}X

Put the value of A and Z

Hence, The element will be ^{161}_{80}X

The sucrose molecule is a large and complex molecule built of carbon, hydrogen, and oxygen. How many sucrose
jek_recluse [69]

Answer:

There are 3.01x10²³ molecules of sucrose

Explanation:

In order to calculate the number of molecules of any atom or compound, we need to use the Avogadro number which is 6.02x10²³. This number could represent atoms or molecules of any mole of compound or atom.

In other words, 1 mole of a certain atom or compound has 6.02x10²³ molecules or atoms.

we have 0.5 moles of sucrose, all we just need to do is a simple rule of 3:

If 1 mole contains 6.02x10²³ molecules

then 0.5 moles will contain:

n° molecules = 0.5 * 6.02x10²³ / 1

<h2>n° molecules = 3.01x10²³ molecules of sucrose</h2>

Hope this helps
