Coaxial cable are used to transmit signals:
Magnet
Electric
Mechanical
Both mechanical and magnet
the number of waves passing through a point in one second is called:
time period
cycle
frequency
amplitude
The displacement produced in the spring is directly proportional to force is called:
Hook’s law
Boyle’s law
Newton’s law
Joule’s law
The oscillations of a system in the presence of which force are called damp oscillations:
Resistive force
Attractive force
Coulomb force
Both a and b
1 GB =
1022MB
1023 MB
1024MB
1025MB
the time period of body attached to spring depend on:
mass
gravitational constant
length
If the displacement in spring is ‘x’ of mass “m” attached with a spring then restoring force is:
F=ma
F=kx
F=-kx
F= m/a
