Answer:
According to Lenz's law the magnet slows down.
Magnet drop without slowing down.
Explanation:
When the magnet is falling in the copper coil, then flux through the coil increases but according to Lenz's law in copper tube current will induce in that direction where the magnetic flux decreases. So, the magnet is repelled and slows down.
And when it is moving down after passing through a copper tube, then the flux decreases and the current will increases in reverse direction due to Lenz's law and will attract a magnet and again due to this it slows down.
If a long slit is cut along the copper then the induced current drops a lot and force also drop. So, the magnet passes through the coil in a shorter time or without slowing down.
Answer:
Please see below as the answer is self - explanatory
Explanation:
a) 10³ = kilo (kilogram = 10³ grams, kilometer= 10³ meters)
Symbol : k.
b) 10⁻² = centi (it is the 100th part of a unit, like centimeter, or centigram) Symbol: c.
c) .1 = deci (it is the tenth part (deci comes from the word that means "ten"in latin) of a unit: decimeter, decigram)
Symbol: d.
d) 10⁻3 = mili (it is a 1000th part of a unit: milimeter, miligram), the name comes from the word used in latin to mean "one thousand".
Symbol: m
e) 1,000,000 = 10⁶ = mega (megawatt)
Symbol: M
f= 0.000001 = 10⁻6 = micro (micrometer, microsecond),
Symbol: μ.
Answer:
This can be part of your paragraph.
Explanation:
From the cornea, the light passes through the pupil. The iris, or the colored part of your eye, controls the amount of light passing through. From there, it then hits the lens. This is the clear structure inside the eye that focuses light rays onto the retina.
Answer:
He could have many different hypothesis, but here is one.
Explanation:
If rubber bands are wider, then the rubber bands will stretch further, because the wider a rubber band is the stronger it is.
Answer:
|A| = 8.06
Explanation:
Given that
Vector A,
We need to find the magnitude of the vector. Let the vector is R = ai + bj. The magnitude of this vector is given by :
In this given question, a = 4 and b = 7
The magnitude of vector A is given by :
|A| = 8.06
So, the magnitude of given vector is 8.06. Hence, this is the required solution.
