Answer:
Part a)
First image
second image
Part b)
First image
Second image
Explanation:
When object is placed between mirror and convex mirror
then for the first image
now from the mirror formula
here we have
For second position of image we will take object for convex mirror to be the position of image formed in plane mirror
so the distance of that image from convex mirror is
now by mirror formula
Part b)
Height of image and height of object is related by the equation
for height of second image
Answer:
V{+7 + 1000
Explanation:
Because Y + 7 + (828 and Y X P + ()
<u>Any time the coin is on the table:</u>
-- gravity acting downwards
-- normal force of the table, acting upwards
<u>Any time the coin is moving:</u>
-- friction force, on the coin's underside
-- air resistance
Both of these act opposite to the direction of the coin's motion.
<u>During the flick, while your finger is still touching the coin:</u>
-- the flicking force, a push exerted by your finger
The force ends as soon as the coin leaves contact with your finger.
The net force on the object is zero, so it has no acceleration. It moves in a straight line and at a constant speed (which may be zero).
Explanation:
Track and Field is a sport, which is includes disciplines of running, jumping, and throwing events. The sport traces back to Ancient Greece. The first recorded examples of this sport were at the Ancient Greek Olympics. In Ancient Greece, only one event was contested, the stadion footrace.
