A) Radio waves are a form of electromagnetic radiation.
TRUE
It is the type of electromagnetic wave with least energy range and longest wavelength range among all
B) Electromagnetic radiation does not require a medium to travel.
TRUE
This radiation can travel through vacuum also and its speed is maximum in vacuum
C) In a vacuum, electromagnetic radiation travels at the speed of light.
TRUE
speed of all electromagnetic radiation is same as speed of light in vacuum
D) Electromagnetic radiation travels in the form of longitudinal waves.
FALSE
All electromagnetic radiation is always in form of transverse waves
So correct options are
<u>A, B, C</u>
Rutherford's model of the atom (ESAAQ) Rutherford carried out some experiments which led to a change in ideas around the atom. His new model described the atom as a tiny, dense, positively charged core called a nucleus surrounded by lighter, negatively charged electrons.
To solve this problem we will apply the concepts related to load balancing. We will begin by defining what charges are acting inside and which charges are placed outside.
PART A)
The charge of the conducting shell is distributed only on its external surface. The point charge induces a negative charge on the inner surface of the conducting shell:
. This is the total charge on the inner surface of the conducting shell.
PART B)
The positive charge (of the same value) on the external surface of the conducting shell is:

The driver's net load is distributed through its outer surface. When inducing the new load, the total external load will be given by,



Because of the law of inertia and it’s effect on the skater
Acceleration = final velocity - inital / time
a = 75-10 / 7
a = 65 / 7
a = 9.29 m/s^2
