<span>They allow us to see distant objects as they were long in the past.
-The further we look into space the further back we look in time.</span>
An object becomes negatively charged when It gains electrons. Option A is correct.
<h3>What is an atom?</h3>
The atom consists of matter that may be split without releasing electrical charges.
It's also the smallest unit of matter with chemical element features. As a result, the atom is the fundamental unit of science.
In the nucleus proton and the neutron is exists. The condition of the atom to be electrically neutral is that the number of the proton and electron should be the same.
An object becomes negatively charged when It gains electrons. Because the electron is a negative cahrge particle.
Hence, option A is correct.

200 ms² is the kinetic energy for an object that weighs 40g and moving at 10 m/s.
<h3>What are kinetic energy ?</h3>
Kinetic energy is the power that an object has had as a result of motion. To accelerate an object, a power must be supplied to it. To apply a force, we must exert effort. The power is transported to the object when work is accomplished, which causes it to move at a new, constant pace.
<h3>What makes kinetic energy so important?</h3>
The capacity to perform work is unquestionably the most important characteristic of kinetic energy. Force acting on to an object while it is traveling is referred to as work. Energy and work are interchangeable because of their close relationship.
<h3>Briefing:</h3>
Using Kinetic Energy Formula:
K.E = 1/2 mv²
K.E. = 1/2 * 40 * 10
K.E. = 200 ms²
