In which type of Eclipse do u see the Sun in the form of a ring

Helga [31]

The type of eclipse in which one sees the sun in the form of a ring is ANNULAR SOLAR ECLIPSE.
Solar eclipse occurs when the moon casts a shadow on the earth.
There are three basic types of solar eclipse, these are total, partial and annular solar eclipse. The annular solar eclipse occurs when the moon covers the sun's center thereby leaving the sun visible outer edges to form a ring of fire around the moon.<span />

A proton is released from rest at the positive plate of a parallelplatecapacitor. It crosses the capacitor and reaches the negat

Triss [41]

Answer:

2.1406 × $10^6$ m/sec

Explanation:

we know that energy is always conserved

so from the law of energy conservation

$qV=\frac{1}{2}mv^2$

here V is the potential difference

we know that mass of proton = 1.67× $10^{-27}$ kg

we have given speed =50000m/sec

so potential difference $V=\frac{\frac{1}{2}\times 1.67\times 10^{-27}50000^2}{1.6\times 10^{-19}}=13.045$

now mass of electron =9.11× $10^{-31}$

so for electron

$\frac{1}{2}\times 9.11\times 10^{-31}v^2=1.6\times 10^{-19}\times 13.045=2.1406\times 10^6 m/sec$

so the velocity of electron will be 2.1406× $10^6$ m/sec

Is work done when falling towards earth while skydiving???

GuDViN [60]

You betcha !

-- Work is done whenever a force acts through a distance.

-- The skydiver has weight. That's the force acting on him.

-- As time goes on, I'm assuming that he falls from one height
to a lower height. That's the distance the force acts through.

-- The work done on him is (force) times (distance)

(his weight) x (distance he falls).

So where is the machine that does all this work ?

-- It's GRAVITY that does the work on him as he falls.

So how did he get all this energy in the first place ?
Where did it come from ?

-- From the airplane that lifted him up to height from which he jumped !
