The number of charge drifts are 3.35 X 10⁻⁷C
<u>Explanation:</u>
Given:
Potential difference, V = 3 nV = 3 X 10⁻⁹m
Length of wire, L = 2 cm = 0.02 m
Radius of the wire, r = 2 mm = 2 X 10⁻³m
Cross section, 3 ms
charge drifts, q = ?
We know,
the charge drifts through the copper wire is given by
q = iΔt
where Δt = 3 X 10⁻³s
and i = 
where R is the resistance
R = 
ρ is the resistivity of the copper wire = 1.69 X 10⁻⁸Ωm
So, i = 
q = 
Substituting the values,
q = 3.14 X (0.02)² X 3 X 10⁻⁹ X 3 X 10⁻³ / 1.69 X 10⁻⁸ X 0.02
q = 3.35 X 10⁻⁷C
Therefore, the number of charge drifts are 3.35 X 10⁻⁷C
Explanation:
The moon is the only natural satellite of the Earth and is fifth largest natural satellite in our solar system. It formed about 4.51 billion years ago.The principal features of the moon that are observable with the unaided eye are the lighter highlands, the dark maria and few large craters such as Tycho.
Answer:
a. The pressure in the tubing is equal to the barometric pressure.
Explanation:
Since in the question it is mentioned that the if you take the stoppert part of the tube than the level of warer would be fall approx 4th floor and if it is continued than it wont be continue but remains constant.
Now here first we do that the tube i.e. connected to the bucket should be taken up. In the first instance, the bucket supplies the water to the tube but it would not increased far away to the level of the barometric pressure
Hence, the correct option is a.
ALL colors are in the visible spectrum.
"Color" is a word we use to describe light that our eyes can detect. If the light has a "color", that means we can see it, and somebody gave it a name. If we can't see it, then we don't have a "color" to describe it.
Every color that has ever been perceived by human eyes is present in the humanly-visible spectrum, except "black".
There are at least hundreds of them. Probably thousands. Maybe millions.
The concept that should be used here is that heat loss is equal to heat gain. In this item, the heat lost by the aluminum pan should be equal to the heat gained by water. Such that,
750 g(0.215 cal/g°C)(T - 24) = (10000 g)(1 cal/g°C)(4°C)
The value of T from the equation is equal to 272°C.
