Answer: 3.49 s
Explanation:
We can solve this problem with the following equation of motion:
(1)
Where:
is the final height of the ball
is the initial height of the ball
is the initial velocity (the ball was dropped)
is the acceleratio due gravity
is the time
Isolating :
(2)
(3)
Finally we find the time the ball is in the air:
(4)

Because in my opinion they do bending of a light wave as it passes at an angle from one medium to another.
Answer:
This question is incomplete
Explanation:
This question is incomplete because of the absence of the time taken to complete one full cycle.
Frequency (<em>f</em>) will be calculated first as
<em>f </em>= <em>N </em>÷<em> t</em>
where <em>N </em>is the number of cycles and <em>t </em>is the time taken to complete one full cycle. The unit for frequency is Hertz (Hz).
To calculate the period, <em>T, </em>the formula below will be used
<em>T </em>= 1 ÷ <em>f</em>
The unit for period is secs
Answer:
7908.92307 W
683330953.248 J
Explanation:
k = Heat conduction coefficient = 0.8 W/(m·°C)
A = Area = 
l = Thickness = 0.65 cm
= 24°C
= 0°C
Rate of heat transfer is given by
The rate of heat transfer is 7908.92307 W
Amount of energy is given by
The energy transferred through the window in one day is 683330953.248 J
