Answer:
1.63103 seconds
Explanation:
= Actual period of clock = 1 second
v = Speed at which the observer is moving = 0.79 c
c = Speed of light =
Time dilation is given by
The period is 1.63103 seconds
Explanation:
As we know that
time = distance/speed
The time used for firs half of the trip was
(1 mi)(12 mi/hour) = 1/12 hours = 5 minutes
The last half of the trip will took 10 minutes, 1/6 hour.
Speed = distance/ time
(1 mil) = (1/6h) = 6 mil/h
so the speed for last half of the trip was = 6mph
the average speed was
(2mil)(1/4 hour) = 8 mil/hour
So the ling's average speed was 8mph.

Answer:
The power of his ideally prescribed eyeglasses is 1.0 D.
Explanation:
Given that,
Image distance = 110 cm
We know that,
Object distance = ∞
We need to calculate the focal length
Using formula of lens
Put the value into the formula
We need to calculate the power of his ideally prescribed eyeglasses
Using formula of power
Hence, The power of his ideally prescribed eyeglasses is 1.0 D.
