The location of image and the height of the image is mathematically given as
di = -40 cm
h=8 cm
<h3>The

upright and enlarged
Question Parameters:
Generally the equation for the is mathematically given as
using mirror equation
1/f = (1/do) + (1/di)
Therefore
1/40 = (1/20) + (1/di)
di = -40 cm
Therefore, Magnification
m = -di/do = hi/h\
m = 40/20 = hi/4
m = 2 = hi/4
image height is
hi = 4*2
h=8 cm

Answer:
The height of the cliff is 28.57 m.
Explanation:
Given;
initial velocity of the rock, u = 12.6 m/s
time of motion, t = 1.45 s
The height of the cliff is given by;
h = ut + ¹/₂gt²
h = (12.6 x 1.45) + ¹/₂(9.8)(1.45)²
h = 18.27 + 10.30
h = 28.57 m
Therefore, the height of the cliff is 28.57 m.
Since the plane is traveling at 100m/s horizontal to the surface of the earth, the crate will always have this horizontal velocity (neglecting air resistance) until it hits the ground. So the answer is 100m/s. Note the vertical speed continues to change as the crate accelerates downward toward earth (again neglecting air effects)
