How much work does the charge escalator do to move 2.30 μC of charge from the negative terminal to the positive terminal of a 3.
loris [4]

Answer:

6.9\times 10^{-6} J

Explanation:

We are given that

Charge=q=2.3\mu C=2.3\times 10^{-6} C

1\mu C=10^{-6} C

Potential difference=V=3 V

We know that

Work done=V\times q

Using the formula

Work done by charge to move from the negative terminal to the positive terminal of battery=2.3\times 10^{-6}\times 3 J

Work done by charge to move from the negative terminal to the positive terminal of battery=6.9\times 10^{-6} J

g When the movable mirror of the Michelson interferometer is moved a small distance X while making a measurement, 246 fringes ar
zhenek [66]

Answer:

X = 69.1 x 10⁻⁶ m = 69.1 μm

Explanation:

The relationship between the motion of the moveable mirror and the fringe count of the Michelson's Interferometer is given by the following formula:

d = mλ/2

where,

d = distance moved by the mirror = X = ?

m = No. of Fringes counted = 246

λ = wavelength of light entering interferometer = 562 nm = 5.62 x 10⁻⁷ m

Therefore,

X = (246)(5.62 x 10⁻⁷ m)/2

Therefore,

<u>X = 69.1 x 10⁻⁶ m = 69.1 μm</u>

What would happen if a bird was a vulture riding on a zebra's back? How would it affect the relationship?
OLEGan [10]
The zebra could be "hen pecked" if the vulture was a hen bird. On the other hand, the two might get along ok. In UK, it they 'd make a useful combination helping each other to cross increasingly dangerous roads (joke).

A skydiver jumps out of a hovering helicopter, so there is no forward velocity. Ignore wind resistance for this exercise. 1. Wha
nevsk [136]
1. What is the skydiver's acceleration?

Initially, like any falling object, a skydiver's downward acceleration is 9.8 meters/seconds^2, or about 28-35 feet per second squared. This acceleration reduces over a few seconds and approaches zero as the skydiver reaches terminal velocity.
