Answer:
The times is 0.688 ms.
Explanation:
Given that,
Inductance L= 0.048 H
Capacitor C= 4\mu F
The current is initially maximum
We know that,
Where,
We need to calculate the time
....(I)
On integrating equation (I)
If
Put the value of
Hence, The times is 0.688 ms.
Net force, i think could be a possible answer <span />
Answer:
A) 0.50 mV
Explanation:
In this problem, we can think the wings of the bird as a metal rod moving across a magnetic field. So, and emf will be induced into the wings of the bird, according to the formula:
where
is the strength of the magnetic field
v = 13 m/s is the speed of the bird
L = 1.2 m is the wingspan of the bird
is the angle between the direction of motion and the direction of the magnetic field
Substituting numbers into the formula, we find
Whenever an object is falling, its potential energy
is decreasing and its kinetic energy is increasing.
Olivia's potential energy is decreasing and her kinetic energy
is increasing as she moves toward the right side of the picture,
all the way from W, through X, to the bottom of the arc.
