If the echo is detected 2 seconds after the ping is transmitted,
then the sound has traveled
(2 sec) x (1533 meter/sec) = 3,066 meters.
But the sound had to travel down from the boat to the bottom, then
get reflected, then travel up from the bottom to the boat. So the
sound actually traveled a distance equal to double the depth.
The depth is (1/2) (3,066 meters) = 1,533 meters .
(about 5,030 feet)
<span>When still rolling your bike had kinetic energy, or energy in the form of motion. The forces resisting this motion--a mixture of many factors including air resistance, tire friction, friction in the hubs of the wheels, etc...--eventually decrease the kinetic energy of the bike to zero as it reaches a complete stop.</span>
D is not a scientific experiment.
Answer:
Yes it is related
Explanation:
Consider 2 points in a rectangular co-ordinate system
The distance between them can be found by
d =
This is clear from the figure attached below
