They do not react with or chemically bond to each other.
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.

<u>Given that</u>
time (t) = 10 s ,
(S) = ?
We know that S = ut+ 1/2 a.t² m
since free fall and no air friction,
a = g = 9.81 m/s² ; initial velocity u= 0
S = 0 + [1/2 × 9.81 ×10²]
<em> S = 490.5 m </em>
We are given with conditions on temperature, pressure and volume of gas. In this problem, we apply ideal gas law PV = nRT to solve what are asked.
1. PV = nRT ; n = m/MM
16.5 x10^6 Pa * 0.003785 m3= n * 8.314 Pa m^3/ mol K * (23+273) K
n = 25.38 mol; mass = 812.08 grams.
2. V at STP is 22.4 L/mol
3. PV = nRT = 1.5 atm * 0.003785 *1000 L = <span>25.38 mol * 0.0821 L atm/mol K * T ; T = 2.72 K
4. P * 55 m3/1000 = 25.38 mol * </span><span>8.314 Pa m^3/ mol K</span><span> * (24+273) K
P = 1139. 45 kPa</span>
If the frequency of an electromagnetic wave is too high or too low : C. It is no longer an electromagnetic wave
If the frequency is too high or too low, the skin depth pf the electromagnetic wave will not be comparable to the plasma length
hope this helps
