Answer:
The frequency of the signal is 2 GHz
Explanation:
Given;
period of the clock signal, T = 500 ps = 500 x 10⁻¹² s
the frequency of the signal is given by;

F = 2 GHz
Therefore, the frequency of the signal is 2 x 10⁹ Hz or 2 GHz
Answer:
24 J
Explanation:
given,
mass of the block 1, M = 3 Kg
initial speed in east direction, u = 5 m/s
mass of the block 2, m = 2 Kg
initial speed in west direction, u' = 2 m/s
final speed of block 1, after collision, V = 1 m/s
Kinetic energy loss during collision = ?
taking east direction positive
using conservation of momentum
M u + m u' = M V + m V'
3 x 5 + 2 x(-2) = 3 x 1 + 2 x V'
2 x V' = 8
V' = 4 m/s
loss in kinetic energy
=
=
=
= 24 J
loss in kinetic energy is equal to 24 J
Transformer. Its an electrical device that uses electromagnetic induction to pass an alternating current (AC) signal from one electric circuit to another, often changing the voltage and electrical current
