Answer:
2) Their kinetic energy increases.
Explanation:
The particles have more kinetic energy because they move around more when they are a liquid.
the mass number of fluorine (F) is 19
C. 19
Answer:
Yes
Explanation:
As long as its a solid, you can count it. It will be hard, but possible.
The answer
the speed of <span>the train traveling in kilometers per minute can be found by using the following method:
v = </span><span>30 miles per hour
</span><span>1 mile = 1.6 kilometers
just do the calculus by changing miles to kilometers
</span>1 mile = 1.6 kilometers, so 30 miles= 1.6 km x 30 = 48 km
so the speed of the train is
v=30 miles / hour = 48km / h = 48km / 60 mn = 0.8 km/ mn
the answer is
<span>C- 0.8 km/min</span>
