Answer:
2.00m
Explanation:
All we need to do to find the wavelength of the first intereference maximum is subtract both values we are given.
8.00 - 6.00 = 2.00m
Best of Luck!
Answer:
About 3.88 meters per second
Explanation:
14km= 14,000m
14,000m per hour
so 14,000 ÷ 60= 233.33 meters per minute
233.33÷60=3.88 meters per second
In simple words, smoothing can be defined as the circuit which is done to eliminate the ripple from the yield of a direct current power supply.
<u>Explanation:</u>
<u>Necessity of smoothing:</u>
- Smoothing can be also applied in the form of a capacitor that acts to decrease or level out variations in a signal. And these capacitors are mostly used after power supply in voltage.
- The yield DC voltage of a half-wave rectifier provided in the figure of a sinusoidal wave.
- In a method to provide a constant DC voltage from a corrected AC source, a filter or smoothing circuit is required.

Answer:
7.1 J
Explanation:
From the question,
Work done by the mover = work done in pushing the crate + work done against friction
W = W'+Wf................. Equation 1
W = mgd+mgμd............ Equation 2
W = mgd(1+μ)................ Equation 3
Where m = mass of the crate, g = acceleration due to gravity, d = distance, μ = coefficient of friction.
Given: m = 46 kg, d = 10.5 mm = 0.0105 m, μ = 0.5
constant: g = 9.8 m/s²
Substitute these values into equation 3
W = 46×9.8×0.0105(1+0.5)
W = 7.1 J
