GPE= height x mass x gravitational field strength
5 x 10 x 9,8=490J
Answer:
Fossil fuels store energy from the sun as
Conduction, since the iron is in direct contact with the clothes.
The number of protons in one atom of an element determines the atom’s identity and the number of electrons determines electrical charge of an element.
<u>Explanation:
</u>
Atoms are made up of protons, neutrons and electrons. The protons and neutrons are enclosed in a specific spherical region at the center of the atom termed as nucleus of the atom. This is because proton is positive charge and neutron is neutral charged high mass particles.
While the electrons are negative charged lighter mass particles. So the electrons will revolve around the nucleus. The protons number in element's one atom helps to identity its chemical properties of the element. While the electrons number in an element will determine the electrical charge and conducting nature of the element.
Answer:
Explanation:
Given that
Volume
As we know that
So
So we cab say that 
is equal to 
.
