Explanation:
Given
Density of Cork 
Considering V be the volume of Cork
Buoyant Force will be acting Upward and Weight is acting Downward along with T
Since density of water is more than cork therefore Cork will try to escape out of water but due to tension it will not
we can write as
where T=tension
Thus Tension T is
Taking 
common
The correct answer is A. Electromagnetic waves can transfer energy without a medium. Heat can be transferred through a vacuum only via radiation. Infrared waves are electromagnetic waves that does not require a medium to travel. Heat is transferred in a vacuum in the form of infrared waves.
FULL ANSWER
Neutrons and protons make up a nucleus and they are in the middle of an atom. Electrons surround the nucleus. Opposite charges attract each other. Because of this, protons do not attract other protons and electrons do not attract other electrons. Instead, protons attract electrons and electrons attract protons. When someone looks at the elements on the periodic table, they can see how many protons are present by looking at the atomic number. Since atoms have to have an equal amount of each, if an element contains 36 protons, it also has 36 electrons.
