A geyser is actually a devise that coverts electrical energy
into heat energy for heating up water. The heating element that is inside the
geyser actually gets heated up and then in turn it heats the water in contact
with it within the geyser. There is also a thermostat device within the geyser
that cuts off the heating when the water temperature reaches the desired level.
This helps in stopping of electrical energy loss. One inlet brings in cold
water while another outlet gets rid of the hot water. When the temperature of
the water falls below the desired level the heating is again started by the
thermostat.
Answer: Lightning is mostly light and electricity, this light that is hitting is going at a rate of 299,792.458 km per second (or 186,282 miles per second) this is so much compared to sound which only travels at about 761 mph (or approximately 332 meters per second). Fun fact: The lightening you are seeing is that coming back to the cloud because the process happens so fast.

Answer:
(a) convex mirror
(b) virtual and magnified
(c) 23.3 cm
Explanation:
The having mirror is convex mirror.
distance of object, u = - 20 cm
magnification, m = 1.4
(a) As the image is magnified and virtual , so the mirror is convex in nature.
(b) The image is virtual and magnified.
(c) Let the distance of image is v.
Use the formula of magnification.
Use the mirror equation, let the focal length is f.
Radius of curvature, R = 2 f = 2 x 11.67 = 23.3 cm
