Answer: 4m
Explanation:
Since the angle of incidence of a plane mirror can be anything from 0 to 90°
Assuming that the place is a perfectly square 4×4m room
The incident ray would be 45° for the choir(object) at a 4m distance, this is still within the range of values.
We do not forget also, that the focal length of a plane mirror is infinity, the organist would in fact see farther than 4m if need be. And wider
Answer:
The height of the bridge is 14.5
Explanation:
Given the following data
t = 2.9 seconds
g = +10m/s^2
Using the below formula
H = ut + 1/2gt^2
Since the initial velocity u = 0
Then, H = 1/2gt^2
H = 1/2 x 2.9 x 10
H = 2.9 x 10 / 2
H = 2.9 x 5
H = 14.5
