Answer:
Explanation:
Earliest standards were dependent on a single frequency/channel to both send and receive. This shared medium creates the same problem as half-duplex coax cable. Because receivers had to wait for the signal before sending a response, this reduced the overall bandwidth.
Other factors affect wireless signal propagation, too, including RF interference, antenna choice, and obstacles such as walls, trees, and even weather (precipitation, for example).
Answer with Explanation:
Mass of pendulum bob, m=0.453 kg
Speed,
2.58 m/s
a.r=75.1 cm=
=0.751 m

Tension in the pendulum cable is given by
Tension=Centripetal force+force due to gravity

Where 
Substitute the values


b.When the pendulum reaches its highest point,then
Final velocity, 
According to law of conservation of energy



Substitute the values



The angle mad by cable with the vertical=

c.When the pendulum reaches at highest point then
Acceleration, a=0
Therefore, the tension in the pendulum cable

Substitute the values


Answer:
Explanation:
Given that,
B(t) = B0 cos(ωt) • k
Radius r = a
Inner radius r' = a/2 and resistance R.
Current in the loop as a function of time I(t) =?
Magnetic flux is given as
Φ = BA
And the Area is given as
A = πr², where r = a/2
A = πa²/4
Then,
Φ = ¼ Bπa²
Φ(t) = ¼πa²Bo•Cos(ωt)
Then, the EMF is given as
ε(t) = -dΦ/dt
ε(t) = -¼πa²Bo • -ωSin(ωt)
ε(t) = ¼ωπa²Bo•Sin(ωt)
From ohms law,
ε = iR
Then, i = ε/R
I(t) = ¼ωπa²Bo•Sin(ωt) /R
This is the current induced in the loop.
