When an electric current is flowing through a wire, there is a magnetic <em>field</em> produced. The lines of magnetic force are circles around the wire.
Answer
given,
mass of the stick = 290 grams = 0.29 Kg
Force on the stick on one side = F = 9 N
force acting perpendicular to stick.
magnitude of acceleration
rate of change of angular momentum is equal to Force
rate of change of angular momentum = 9 N
F = m a


a = 31.034 m/s²
Direction of motion will in the direction of force application or in the direction of change of velocity
Answer:
62.5 miles per hour
Explanation:
Speed = Distance travelled / Time taken
Speed = 125/2 = 62.5
You derive the units of the speed...by using the speed formula....,
Speed = Distance/Time
Speed = miles/hour
Hence the units for the speed = miles/hour
Answer:
The electron’s velocity is 0.9999 c m/s.
Explanation:
Given that,
Rest mass energy of muon = 105.7 MeV
We know the rest mass of electron = 0.511 Mev
We need to calculate the value of γ
Using formula of energy


Put the value into the formula


We need to calculate the electron’s velocity
Using formula of velocity




Put the value into the formula



Hence, The electron’s velocity is 0.9999 c m/s.
Answer: 4.74 mm
Explanation:
We can solve this problem with the following equation:
(1)
Where:
is the Young modulus for femur
is the stress (force
applied per unit of transversal area
) on the femur
Being:
the compression the femur can withstand before breaking
is the length of the femur without compression
Writing the data in equation (1):
(2)
(3)
Isolating
:
(4)
(5) This is the compression in meters
Converting this result to millimeters:
