To solve this problem we need to use the induced voltage ratio law with respect to the number of turns in a solenoid. So
For the given values we have to
Replacing we have that,
Therefore the RMS value for secondary is 30V.
The current can be calculated at the same way, but here are inversely proportional then,
Replacing we have
Therefore the rms value of current for secondary is 40mA
Answer:
9.6 rad/s
Explanation:
= length of the metal rod = 50 cm = 0.50 m
= Mass of the long metal rod = 780 g = 0.780 kg
Moment of inertia of the rod about one end is given as
= force applied by the hammer blow = 1000 N
Torque produced due to the hammer blow is given as
= time of blow = 2.5 ms = 0.0025 s
= Angular velocity after the blow
Using Impulse-change in angular momentum, we have
Answer:
h = 27.17 m
Explanation:
First, we will calculate the total mechanical energy of the system at the bottom point of the third loop:
Mechanical Energy = Kinetic Energy + Potential Energy
where,
E = Total Mechanical Energy = ?
m = mass of the roller coaster = 1200 kg
v = velocity of the roller coaster = 22 m/s
g = acceleration due to gravity = 9.81 m/s²
h = height of roller coaster = 2.5 m
Therefore,
Now, the total mechanical energy at the top position of the first hill must also be the same:
where,
v = 0 m/s
h = ?
Therefore,
<u>h = 27.17 m</u>
