Answer:
A. Time Division multiple Access (TDMA)
Explanation:
Time-division multiple access (TDMA) is a channel access method for shared-medium networks
It allows several users to share the same frequency channel by dividing the signal into different time slots. The users transmit in rapid succession, one after the other, each using its own time slot.
Answer:
Explanation:
Given height of lamp from the ceiling = 2.6m
mass of the lamp = 3.8kg
acceleration due to gravity = 9.81m/s²
As the body falls to the ground, it falls under the influence of gravity.
Gravitational potential energy = mass*acc due to gravity * height
Gravitational potential energy = 3.8*2.6*9.81
Gravitational potential energy = 96.923 Joules
b) Kinetic energy = 1/2 mv²
m = mass of the body (in kg)
v = velocity of the body (in m/s²)
To get the velocity v, we will use the equation of motion 

Since mass = 3.8kg

c) To know how fast the lamp is moving when it hits the ground, we will use the formula. When the body hits the ground, the height covered will be 0m. this means that the body is not moving once it hits the ground. It stays in one position. The energy possessed by the body at this point is potential energy. The correct answer is therefore 0 m/s
Answer:
a)
b)
c)
d)
e)
Explanation:
Given that
d = 2 cm
V = 200 V

We know that
F = E q
F = m a
E = V/d
So
m a = q .V/d b
---------1
The mass of electron

The charge on electron

Now by putting the all values in equation 1


We know that
a)
s = 0.1 cm


b)
s = 0.5 cm


c)
s = 1 cm


d)
s = 1.5 cm


e)
s = 2 cm


The friction force is given by:

Where μ is the coefficient of friction (static or kinetic) and

is the normal force. So we say the friction force is directly proportional to the normal force with a constant of proportionality equal to the coefficient of friction.
