Answer:
magnetic field strength is 0.315852 T
Explanation:
Given data
thick = 0.103 mm = 0.103 × 10^-3 m
charge-carrier density = 1.11 × 10^25 m^–3
hall voltage = 3.47 mV = 4.99 × 10^-3 V
current = 2.89 A
to find out
magnetic field strength
solution
we will apply here magnetic field strength formula i.e
magnetic field strength = hall voltage × charge-carrier density × magnitude of charge electron × thick / current
here put all these value and magnitude of charge electron is 1.6×10^-19 C
magnetic field strength = hall voltage × charge-carrier density × magnitude of charge electron × thick / current
magnetic field strength = 4.99 × 10^-3 × 1.11 × 10^25 × 1.6×10^-19 × 0.103 × 10^-3 / 2.89
magnetic field strength = 0.912811 / 2.89
magnetic field strength is 0.315852 T
Answer:
a = 5 [m/s²]
Explanation:
We know from Newton's second law that the sum of forces on a body is equal to the product of mass by acceleration.
∑F = m*a
where:
F = total force = 50 [N]
m = mass = 10 [kg]
a = acceleration [m/s²]
Now replacing:
Explanation:
Potential Into Kinetic
Swings work by converting potential energy into kinetic energy, then kinetic energy back into potential energy, over and over again. The kinetic energy is the fast part of swinging; it's the speed you have as you rush back and forth. Potential energy is the high part of swinging.
