Suppose a NASCAR race car rounds one end of the Martinsville Speedway. This end of the track is a turn with a radius of approxim
1 answer:
Answer:
Centripetal acceleration of the car is 17.4 m/s²
Explanation:
It is given that,
Radius of the track, r = 57 m
Speed of car, v = 31.5 m/s
We need to find the centripetal acceleration of the race car. The formula for the centripetal acceleration is given by :
So, the centripetal acceleration of the race car is 17.4 m/s². Hence, this is the required solution.

Answer:
(a) 2.8 V
(b) 5.6 V
(c) 9.8 V
Explanation:
Given:
Frequency of the generator (f) = 1300 Hz)
Terminal voltage (V) =12.0 V
Resistance of resistor (R) = 14.0 Ω
Capacitance of capacitor (C) = 4.40 μF = 4.40 × 10⁻⁶ F
Inductance of the inductor (L) = 6.00 mH = 6.00 × 10⁻³ H
In order to find the voltages across each, we first need to find the reactance and impedance.
Reactance of the inductor is given as:
Reactance of the capacitor is given as:
Now, impedance is given as:
Current across the circuit is given as:
As resistor, capacitor and inductor are connected in series, the current across each of them is same and equal to total current in the circuit.
(a)
Voltage across the resistor is given as:
Therefore, the voltage across resistor is 2.8 V.
(b)
Voltage across the capacitor is given as:
Therefore, the voltage across the capacitor is 5.6 V.
(c)
Voltage across the inductor is given as:
Therefore, the voltage across the inductor is 9.8 V.
