Answer:
3 volts
Explanation:
Number of turns in primary coil = = 100
Number of turns in secondary coil = = 200
Voltage across primary coil = = 1.5 volts
Voltage across secondary coil = = ?
In a transformer, the ratio of number of turns of primary to secondary coil is equal to the ratio of the respective voltages i.e.
Using the given values, we get:
Thus, the voltage measure across secondary coil would be 3 volts
The maximum speed is 10.4 m/s
Explanation:
For a body in uniform circular motion, the centripetal acceleration is given by:
where
v is the linear speed
r is the radius of the circular path
In this problem, we have the following data:
- The maximum centripetal acceleration must be
where is the acceleration of gravity. Substituting,
- The radius of the turn is
r = 10 m
Therefore, we can re-arrange the equation to solve for v, to find the maximum speed the ride can go at:
