Answer:
Explanation:
Impedence of the circuit = peak voltage / peak current
= 5.8 / 51 x 10⁻³
= 113.725 ohm.
1 / wC =113.725
w = 1 / (113.725 x 22 x 10⁻⁹ )
= 10⁹ / 2.5 x 10³
=10⁶ / 2.5
40 x 10⁴
frequency n = 40 x 10⁴ / 2 x 3.14
6.37 x 10⁴ Hz.
b ) charge on the capacitor = 1 C
V = Q / C
= Charge / capacitor
= 1 / 22 x 10⁻⁹
4.54 x 10⁷ V.
Answer: 13.2 seconds.
Explanation: using equation of motion; S= ut +1/2at² where u = initial velocity=0
S= distance travelled
a = acceleration due gravity
t= time.
1 foot = 0.305m so,
S= 2860 feet =872.3m
S= ut+1/2 at²
872.3 = 0×t + 1/2×10 × t²
872.3 =0 + 5t²
T²= 872.3/5
T²= 174.46
Take the square root of T we then have;
t = 13.2 seconds to one decimal place.
Answer: 3 seconds
Explanation:
Initial velocity(u) of projectile A in vertical direction = 0m/s
acceleration due to gravity a=g=9.81m/s^2
Time taken(t) of projectile A = 3s
Initial velocity of projectile B = 0m/s(vertical direction)
We can get height of cliff using parameters of projectile A since it's the same location.
Height(S) = u×t + 0.5×a×t^2
u =0
S= 0.5×9.81×3^2 = 44.145m
Time taken for projectile B to reach the ground:
S = u×t + 0.5×a×t^2
u =0, S=44.145m, a=9.81m/s^2
44.145 = 0.5×9.81×t^2
44.145 = 4.905×t^2
44.145 ÷ 4.905 = t^2
9 = t^2
t = sqrt(9)
t = 3seconds
