PtichkaEL [24]

Answer:

t = 5.19 s

Explanation:

We have,

Height of the cliff is 132 m

It is required to find the time taken by the ball to fall to the ground. Let t is the time taken. So, using equation of kinematics as :

y=ut+\dfrac{1}{2}gt^2\\\\\text{since}\ u=0\\\\y=\dfrac{1}{2}gt^2\\\\t=\sqrt{\dfrac{2y}{g}}\\\\t=\sqrt{\dfrac{2\times 132}{9.8}}\\\\t=5.19\ s

So, it will take 5.19 seconds to fall to the ground.

describe the charge, mass and the location of each subatomic particle and the role each plays in determining the properties of a
Harrizon [31]

Explanation :

An atom is a smallest particle of matter. An atom consists of protons, neutrons and electrons. These are three subatomic particles.

Protons are positively charged species while neutrons are negatively charged species. Electrons revolves around an atom.

Charge :

The charge of an electron is negative or -1.6\times 10^{-19} \ C

The charge of proton is +e or   1.6\times 10^{-19} \ C

Neutron has no charge.

Mass :

Atomic mass of electron is 9.1\times10^{-31}\ Kg

Atomic mass of proton is 1.67\times10^{-27}\ Kg

Atomic mass of neutron is 1.67\times10^{-27}\ Kg

Both protons and neutrons are located inside the nucleus at the center.

Charge, atomic mass and location determines the properties of an atom. Atomic mass tells about the number of protons and neutrons inside an atom.  Electric charge tells us the number of electrons gain or lost.
