Answer:
<em>v=40 m/s south</em>
Explanation:
<u>Momentum
</u>
It's a physical magnitude that measures the product of the mass by the velocity of a particle. Its units in the International System is kg.m/s and the formula is

Where m is the mass and v the velocity of the particle. If we wanted to solve for v, we have

The baseball has a momentum of 6.0 kg.m/s south and mass of 0.15kg, thus

The velocity is directed to the south
Hello,
To solve we need to know the formula for speed
The formula is D/T=S (Distance of time=speed)
Now all we have to do is plug in the numbers.
20/40= 1/2 or 0.5
SO the speed is 0.5 m/s
Have a great day!
Answer:
at the melting point and boiling point
Explanation:
the heat abdorbed is used to break down the forces holding the particles together to allow it to change its state
It's number three on your worksheet. ;)
In my opinion, i think the first one is the best one since we're cutting down on paper wasted in mails when its better to do it online.
"paying bills online instead of sending paper through mail"
