Answer:

0.6 seconds or 600 miliseconds

Explanation:

So if 1 meter requires 3 milliseconds, 200 meters would equal 600 milliseconds.

If you want to know how to get 600, you do 3*200

600 milliseconds = 0.6 seconds!

Hope it helps

Calculate the recoil velocity in the horizontal direction, in meters per second, of a 1.25-kg plunger that directly interacts wi

mart [117]

Answer:

$v_1=-8.19\ m/s$ '

Explanation:

It is given that,

Mass of the plunger, $m_1=1.25\ kg$

Mass of the bullet, $m_2=0.0175\ kg$

Initially both plunger and the bullet are at rest, $u_1=u_2=0$

Final speed of the bullet, $v_2=585\ m/s$

Let $v_1$ is the final speed of the plunger. Using the conservation of momentum to find it. The equation is as follows :

$m_1u_1+m_2u_2=m_1v_1+m_2v_2$

Since, $u_1=u_2=0$

$m_1v_1+m_2v_2=0$

$v_1=-\dfrac{m_2v_2}{m_1}$

$v_1=-\dfrac{0.0175\times 585}{1.25}$

$v_1=-8.19\ m/s$

So, the recoil velocity of the plunger is 8.19 m/s. Hence, this is the required solution.

The sound level at 1.0 m from a certain talking person talking is 60 dB. You are surrounded by five such people, all 1.0 m from

Hunter-Best [27]

Answer:

66.98 db

Explanation:

We know that

$L_T=L_S+10log(n)$

L_T= Total signal level in db

n= number of sources

L_S= signal level from signal source.

$L_T=60+10 log(5)$

= 66.98 db
