can you have all of them as possibilities ???
Answer:
A = 5.6μs
B = 178.57kHz
C = 2.8μs
Explanation:
A. It takes ¼ of the period of the circuit before the total energy is converted from electrical energy in the capacitor to magnetic energy in the inductor.
t = T/4
T = 4*t
T = 4 * 1.4 = 5.6μs
B. f = 1/T
Frequency is the inverse of period
f = 1 / 5.6*10⁻⁶
f = 178571.4286Hz
f = 178.57kHz
C. time taken for maximum energy to occur is T/2
t = 5.6 / 2 = 2.8μs
Use the kinematics equation:
d = vt + 1/2at^2.
In this problem,
v = 15 m/s.
a = 3 m/s^2,
t = 10 s,
So:
d = 15(10) + 1/2*(3)*(10^2) = 300 meters

Answer: 180N/m(to 2 significant figures)
Explanation:
According to hooked law which states that the extension of a material is directly proportional to the applied force provided that the elastic limit is not exceeded. Mathematically, F = ke where;
F is the applied force in newtons
k is the elastic/spring constant in N/m
e is the extension in meters
Given applied force = 35N
extension = 20cm = 0.2m
Since F = ke,
k = F/e = 35/0.2
k = 175N/m
The spring constant is 175N/m
= 180N/m (to 2significant figures)
