How can i calculate distances between objects by using the concepts of echo location

1 answer:

5 0

Send wave from your location to the object and wait until echo is back.
Measure the time taken.

If you know the speed of wave (say sound wave), than just multiply by half time taken wave to return

The tip of a nail exerts tremendous pressure when hit by a hammer because it exerts a large force over a small area. What force

yanalaym [24]

Answer:

Force, F = 2714.33 N

Explanation:

It is given that,

Diameter of the circular tip, d = 1.2 mm = 0.0012 m

Radius, r = 0.0006 m

Pressure acting on the hammer, $P=2.4\times 10^9\ N/m^2$

Let F is the force exerted on a nail. It can be calculated using the definition of pressure exerted. Its formula is given by :

$P=\dfrac{F}A}$

$F=P\times \pi r^2$

$F=2.4\times 10^9\ N/m^2 \times \pi (0.0006\ m)^2$

F = 2714.33 N

So, the force exerted on a nail 2714.33 N. Hence, this is the required solution.
