B. Let me know if that was correct :)
Answer:
The period of oscillation is 1.33 sec.
Explanation:
Given that,
Mass = 275.0 g
Suppose value of spring constant is 6.2 N/m.
We need to calculate the angular frequency
Using formula of angular frequency
Where, m = mass
k = spring constant
Put the value into the formula
We need to calculate the period of oscillation,
Using formula of time period
Put the value into the formula
Hence, The period of oscillation is 1.33 sec.
Answer:
A capacitor with capacitance C is initially charged with charge q. At time t=0, a switch is thrown to close the circuit connecting the capacitor in series with a resistor of resistance R. (see image below)
What is the current I0 that flows through the resistor immediately after the switch is thrown? Express your answer in terms of any or all of the quantities q, R, and C.
Explanation:
charge on the capacitor,
q = CV
C is the capacitance of the capacitor
V is the voltage across the capacitor
Determine the current flowing through the resistor after the switch is thrown
According to Ohm’s law, current flowing through the resistor is ,
V is the voltage across the resistor
R is the resistance of the resistor
since
Current through the resistor immediately after the switch is thrown
The answer is B: it has made repetitive tasks easier
