Number 1 is the correct answer
Answer:
Physical properties are used to observe and describe matter. Physical properties can be observed or measured without changing the composition of matter. These are properties such as <em>mass, weight, volume, and density.</em>
Answer:
In an air compressor, a rotor spins, causing a piston to move up and down. When the piston goes down, freestanding air is pulled into a chamber. Then, the air is compressed and forced back outward as the piston rises back up.
Explanation:
The energy which is required to split a nucleus into its discrete neutrons and protons is said to be nuclear binding energy.
Using the formula for nuclear binding energy:
E = Δmc²
where,
E = nuclear binding energy
Δm = mass defect
c = speed of light
Substitute the given value of mass defect and speed of light in above formula:
E =
E =
= Joule.
E=
Thus, nuclear binding energy of an atom is .
