The relationship between velocity (v), wavelength (w) and
frequency (f) is expressed as:
v = w f
Plugging in the given values into the equation:
v = 0.643 m (3.25 e 10 Hz)
Where Hz = 1 / s , therefore:
v = 0.643 m (3.25 e 10 / s)
v = 2.09 <span>e 10 m / s</span>
Answer: 219,344.5 j
Explanation:
from the question we have the following parameters
mass of barge (m) = 5 x 10^4 kg
angle of ropes (θ) = 45 degrees
force by each mule (F1) = 1.10 kN = 1100 N
force by each mule (F2) = 1.10 kN = 1100 N
distance (s) = 141 m
work done by the mules = force x cos θ x distance
since we are calculating the force of both mules we have to both mules before we can use in the equation
force = 1100 + 1100 = 2200 N
work done = 2200 x cos (45) x 141
work done = 219,344.5 j
Answer:
(D) Car A is not accelerating, but car B is accelerating.
Explanation:
Answer:
0.0173 V
Explanation:
PARAMETERS GIVEN:
Inductance, L = 2 mH = 0.002 H
Time interval, dt = 0.15 s
Change in current, dI = 1.5 - 0.2 = 1.3 A
The magnitude of the induced EMF is given as:
EMF = | -L*dI/dt |
EMF = (0.002 * 1.3) / 0.15
EMF = 0.0173 V
Answer:
Refraction is an effect that occurs when a light wave, incident at an angle away from the normal, passes a boundary from one medium into another in which there is a change in velocity of the light. The wavelength decreases as the light enters the medium and the light wave changes direction.
