Refer to the diagram shown below.
Let T = the tension in each wire.
For equilibrium,
2T cos(50°) = 150 N
1.2856T = 150
T = 116.677 N ≈ 117 N
Answer: 117 N
Answer:
Explanation:650
colour* wavelength (nm) energy (eV)
red 650 1.91
orange 600 2.06
yellow 580 2.14
green 550 2.25
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.
Atom is IONISED. charge is +1.6 x 10^-19 Coulombs
Answer:
1. Doppler Effect = The apparent change in frequency perceived when the source of sound is approaching or moving away from an observer
2. Beats = The vibration of an object at its natural frequency, caused by a force or wave of the same frequency
3. Resonance = a series of alternating reinforcements and cancellations produced by the interference of waves
4. Shockwave = The cone-shaped wave made by a particle moving faster than the speed of a wave in that medium
