A magnet keeps a cabinet door closed.
The Sun pulls on Earth as Earth moves around the Sun.
The protons in the nucleus of a carbon atom are held together.
An example of the strong force in action is the protons in the nucleus of a carbon atom which are held together.
An atom is defined as the smallest unit of matter which forms an element. Every form of matter whether solid,liquid , gas consists of atoms . Each atom has a nucleus which is composed of protons and neutrons and shells in which the electrons revolve.
The protons are positively charged and neutrons are neutral and hence the nucleus is positively charged. The electrons which revolve around the nucleus are negatively charged and hence the atom as a whole is neutral and stable due to presence of oppositely charged particles.
Atoms of the same element are similar as they have number of sub- atomic particles which on combination do not alter the chemical properties of the substances.

It would be D) The protons in the nucleus of a carbon atom are held together.
Explanation:
Strong forces only work in the nuclei
B.Lava Plateau
C.Dome Mountains
D.Shield Mountains
By Pleistocene ice age is meant the glacial periods that appeared in the Pleistocene. The Pleistocene is the first epoch of the Quaternary. It is an epoch when there was a so called ''ice age'' on the Earth, or rather a glacial period. During this ice age the planet had much lower temperatures on a global scale. The climate was also much drier. Lot of ocean water was frozen in the ice sheets that were stretching deep into the North American and Eurasian continents, which resulted in much lower sea levels that today as well. The places further north than 40 degrees of latitude were almost exclusively covered with ice, so life was almost impossible apart from some coastline places.
B. Yes, she is accelerating as she turns and changes direction.
C.No, she is not accelerating because there is not an incline to the track.
D.No, she is not accelerating because her speed is constant.
D.No, she is not accelerating because her speed is constant.
The rate of change of velocity with respect to time is known as acceleration.
acceleration =change in velocity/time
As she is running at constant speed and there is no change in velocity so she is not accelerating.
