Explanation:

When the balloon is kept near to the wall not touching the wall, there is a force of electrostatic attraction so that the balloon moves towards the wall and stick to it.

Answer:

$v = 20\pi sec^2\theta$

Explanation:

As we know that the angle made with the vertical is given so we have

$tan\theta = \frac{x}{10}$

so we have

$x = 10 tan\theta$

now differentiate both sides with time

$v = \frac{dx}{dt} = 10 sec^2\theta \frac{d\theta}{dt}$

$v = 10 \omega sec^2\theta$

now we know that

$\omega = 2\pi f$

$\omega = 2\pi (\frac{60}{60})$

$\omega = 2\pi$

now we have

$v = 10(2\pi) sec^2\theta$

$v = 20\pi sec^2\theta$

A ray diagram without the produced image is shown.

Mashutka [201]

The answer is real and smaller than the object. The image point of the top of the object is the point where the two refracted rays intersect. Tracing the entire image having the same distance from the mirror as the image of the top of the object and with the bottom on the principal axis. Hence, a real inverted image will be formed for an object outside the focal point.

How often do the earth's magnetic poles switch?
