Answer:
The frequency of oscillation of the simple pendulum is 0.49 Hz.
Explanation:
Given that,
Mass of the simple pendulum, m = 0.35 kg
Length of the string to which it is attached, l = 1 m
We need to find the frequency of oscillation. The frequency of oscillation of the simple pendulum is given by :

So, the frequency of oscillation of the simple pendulum is 0.49 Hz. Hence, this is the required solution.
PART A)
If we increase the voltage supply in an electromagnet then it will increase the current that is flowing in it
So here due to increase in current there will be increase in the magnetic field due to that electromagnet
PART B)
Here in electric generator the current is produced by rotating a coil between two strong magnets.
So here mechanical energy of rotation of coil is converted into electromagnetic energy.
PART C)
Step up transformer convert the lower voltage input into higher voltage output
here number of turns of coil in output side or secondary number of coils is more than the number of coils in primary side or input side
PART D)
Force on a moving charge is given by

here we know that
q = 0.000600 C

B = 4.21 T
now from above equation we have


direction of force is given by right hand thumb rule
using that rule we got force downwards
At the most distant point, the size of the speed is zero (0 m/s). This is a direct result of preservation of vitality. PE = KE. The most distant far from the harmony position is the maximum PE. Hence it can have no KE. No KE implies no speed since KE = .5mv2
Answer:
Diffraction
Explanation:
Diffraction is the bending of waves around obstacles and openings. The amount of diffraction increases with increasing wavelength.
Answer:
Magnetic compass
Explanation:
A magnetic field is a field that describes the magnetic effect of electric charges in a relative motion.
Magnetic field allows magnets to interact without contact. The principle involved in the function of the compass is that a magnetic field exerts a force on any moving charge and can be measured and detected by this effect.
