Answer:
f = c / λ = wave speed c (m/s) / wavelength λ (m). The formula for time is: T (period) = 1 / f (frequency). λ = c / f = wave speed c (m/s) / frequency f (Hz). The unit hertz (Hz) was once called cps = cycles per second.

Answer:
Voltage across element X is 49.26 volts
Explanation:
The kirchhoff's voltage law states that the algebraic sum of voltages around a closed loop is equal to zero.
Applying the kirchhoff's voltage law in loop yields,
-160 + V₁ + V₂ + V₃ + Vₓ + 60 + V₄ = 0
-160 + 60 + V₁ + V₂ + V₃ + Vₓ + V₄ = 0
But we know that V = IR
-100 + IR₁ + IR₂ + IR₃ + IRₓ + IR₄ = 0
IR₁ + IR₂ + IR₃ + IRₓ + IR₄ = 100
I(R₁ + R₂ + R₃ + Rₓ + R₄) = 100
I = 100/(R₁ + R₂ + R₃ + Rₓ + R₄)
Substitute the given resistor values
I = 100/(18k + 20k + 45k + 100k + 20k)
I = 100/203k
I = 100/203×10³
I = 0.0004926 A
The voltage drop at element x is
Vₓ = IRₓ
Vₓ = 0.0004926*100×10³
Vₓ = 49.26 V

Answer:
(4.5125 * 10^-3 kg.m^2)ω_A^2
Explanation:
solution:
Moments of inertia:
I = mk^2
Gear A: I_A = (1)(0.030 m)^2 = 0.9*10^-3 kg.m^2
Gear B: I_B = (4)(0.075 m)^2 = 22.5*10^-3 kg.m^2
Gear C: I_C = (9)(0.100 m)^2 = 90*10^-3 kg.m^2
Let r_A be the radius of gear A, r_1 the outer radius of gear B, r_2 the inner radius of gear B, and r_C the radius of gear C.
r_A=50 mm
r_1 =100 mm
r_2 =50 mm
r_C=150 mm
At the contact point between gears A and B,
r_1*ω_b = r_A*ω_A
ω_b = r_A/r_1*ω_A
= 0.5ω_A
At the contact point between gear B and C.
At the contact point between gears A and B,
r_C*ω_C = r_2*ω_B
ω_C = r_2/r_C*ω_B
= 0.1667ω_A
kinetic energy T = 1/2*I_A*ω_A^2+1/2*I_B*ω_B^2+1/2*I_C*ω_C^2
=(4.5125 * 10^-3 kg.m^2)ω_A^2
