A. What is the S.l unit of acceleration?<br>m<br>m/s o<br>m/s2<br>N

kifflom [539]

Explanation:

The SI unit of acceleration is the metre per second squared (m s−2); or "metre per second per second", as the velocity in metres per second changes by the acceleration value, every second.

How many electrons make up a charge of - 30.0 μc?

Ymorist [56]

Each electron has a charge of

$q=-1.6 \cdot 10^{-19}C$

In this problem, the total charge is

$Q=-30.0 \mu C=-30.0 \cdot 10^{-6} C$

Therefore, the number of electrons contained in this total charge will be given by the total charge divided by the charge of a single electron:

$N=\frac{Q}{q}=\frac{-30.0 \cdot 10^{-6} C}{-1.6 \cdot 10^{-19} C}=1.88 \cdot 10^{14}$

You throw a 50.0g blob of clay directly at the wall with an initial velocity of -5.00 m/s i. The clay sticks to the wall, and th

Whitepunk [10]

Answer:0.25 kg-m/s

Explanation:

Given

mass of blob $m=50 gm$

initial velocity $u=-5 m/s\ \hat{i}$

time of collision $t=20 ms$

we know Impulse is equal to change in momentum

initial momentum $P_i=mu$

$P_i=50\times 10^{-3}\times (-5)=-0.25 kg-m/s$

Final momentum $P_f=50\times 10^{-3}v$

$P_f=0$ as final velocity is zero

Impulse $J=P_f-P_i$

$J=0-(-0.25)$

$J=0.25 kg-m/s$
