How long would it take for a sound impulse to travel through a copper rod 2.0 km long?_____ s
0.057
0.57
1.75
17.5

Answers

At standard temperature, shear force propagation occurs at 3570 meters per second. Thus for a copper rod (assumed at ST) measuring 2 km, an impulse would cross its length in 2/3.57 = .56022409 seconds— thus approximately .57 seconds.

it would take roughly half a second so base that off your answers and you could get the right answer

hope that helped

Starting from rest, Christina experiences 24.5 m/s2 of acceleration to take off from an aircraft carrier for 5 seconds. How long does the runway need to be? Round to the nearest meter.

Answers

Answer:

The length of the runway to the nearest meter is 306 m.

Explanation:

Given:

Initial velocity of Christina is, $u=0\ m/s(Rest)$

Time taken is, $t=5\ s$

Acceleration experienced by Christina is, $a=24.5\ m/s^2$

The length of the runway is, $d=?$

Now, we use Newton's equation of motion that relates the distance, initial velocity, time and acceleration.

So, we have the following equation of motion:

$d=ut+(1)/(2)at^2$

Plug in all the given values and solve for 'd'. This gives,

$d=0+(1)/(2)* 24.5* 5^2\n\nd=(1* 24.5* 25)/(2)\n\nd=(612.5)/(2)\n\nd=306.25\approx 306\ m(\textrm{Rounding to nearest meter})$

Therefore, the length of the runway to the nearest meter is 306 m.
