Answer:
76 minutes.
Explanation:
There are 60 minutes in an hour + 16 minutes= 76 minutes.
Since we are only looking at the vertical height, we can use the free fall equation to find the height:
h = 0.5*g*t^2, where h is height in m, g is acceleration due to gravity (9.81 m/s^2), and t is time in seconds
h = 0.5*(9.81 m/s^2)*(3.7 s)^2
h = 67.15 m
Therefore, the 7th floor window is 67.15 m above ground level.
Answer:
Energy is stored in the bonds between atoms
The human eye is one of the most valuable sense organ. The closest object that a typical young person with normal vision can focus closest to is 25 cm
The lens in the eye forms the image on the retina. The image formed is real and inverted. The retina is a very delicate membrane containing numerous light sensitive cells.
This light sensitive cells gets activated when light falls on it and generates electric signals. These electric signals are sent to the brain via the optic nerves present in the eye. The brain finally processes these signals and thus we see the object clearly.
The ability of the lens of the eye to adjust its focal length accordingly is called the power of accommodation,
The minimum distance, at which the object can be seen clearly without any strain is called the least distance of distinct vision.
To see an object clearly without any strain is when we place it at about 25 cm from the eye.
