B south because north polarities line up with the opposite polarities
The common value for “Speed of light in vacuum” is
metre per second.
Answer: Option b
<u>Solution:
</u>
Speed of light can be defined as the speed with which light waves propagate in different medium. In vacuum, speed of light is 186,282 miles per second or 299,792 km/s which is rounded off as
.
“Speed of light in vacuum” is a universal constant and usually represented by ‘c’. Light waves travels at a speed of
metre per second in vacuum.
Well, you should TAKE COVER UNDER A STUDY DESK, TABLE OR AGAINST AN INSIDE WALL. Which is C. This is because, doing this protects you from the falling objects. If you do A or B, you will probably get crushed by falling objects because you are exposed. Hope I helped.
Answer:

Explanation:
Relevant Data provided
Area which indicates A = 2.3 cm^2 = 2.3 x 10^-4 m^2
Distance which indicates d = 1.50 x 10^-3 m
Voltage which indicates V = 12 V
According to the requirement, the computation of value of its capacitance is shown below:-


= 
Therefore for computing the capacitance we simply applied the above formula.
Chlorine needs to gain one electron and sodium needs to lose one electron
