i would sat C then the impact is weaker
Answer:
The current in the circuit at a time interval of τ seconds after the switch has been closed is 0.123 A
Explanation:
The time constant for an R and C in series circuit is given by τ = RC.
R = 3000 ohms, C = 0.5 × 10⁻⁶ F = 5.0 × 10⁻⁷ F
τ = 3000 × 5 × 10⁻⁷ = 0.015 s
The voltage across a capacitor as it charges is given be
V(t) = Vs (1 - e⁻ᵏᵗ)
where k = 1/τ
At the point when t = τ, the expassion becomes
V(t = τ) = 1000 (1 - e⁻¹) = 0.632 × 1000 = 632 V
Current flows as a result of potential difference,.
Current in the circuit at this time t = τ is given by
I = (Vs - Vc)/R
Vs = source voltage = 1000 V
Vc = Voltage across the capacitor = 632 V
R = 3000 ohms
I = (1000 - 632)/3000 = 0.123 A
Started at 4.30 p.m ,15+45+30=1 hr 30 mins,6.00-1 hr 30 mins=4.30 p.m
Answer:
the correct answer will be 6.82 %that is 7%
p(1.27)-q(0.83) =x=0.44
0.02+0.01 =0.03 (maximum uncertainty)
percentage uncertainty =0.03/0.44×100 %
=6.82%
=7%

Answer:
708.3 Hz
Explanation:
For an open-air column, like the empty can, the fundamental frequency is given by

where
v = 340 m/s is the speed of sound
L is the length of the column
In this problem, the length of the bottle is
L = 24 cm = 0.24 m
Therefore, the fundamental frequency is
