The train cars moves in the same direction when the engine car begins

moving to the left.

<h3>What is Law of magnetism?</h3>

The law of magnetism states that like poles repel and unlike poles attract.

In substances which have magnetic field, they are known to attract each

other.

The engine and train car are highly magnetized which results in them

moving in the same direction when they are in close contact with one

another.

If a 250.0 mL sealed plastic bag starts out at a temperature of 19.0 °C and after sitting in the sun reaches a temperature of 60
Marizza181 [45]

Answer:

D

Explanation:

If the pressure remains constant then the temperature and Volume are all that you have to consider.

Givens

T1 = 19oC = 19 + 273 = 292o K

T2 = 60oC = 60 + 273 = 333oK

V1 = 250 mL

V2 = x

Formula

V1/T1 = V2/T2

250/292 = x/333                

Solution.

The solves rather neatly.  Multiplly both sides by 333

250*333 / 292 = 333 *x / 333

Do the multiplication

250 * 333 / 292 = x

83250 / 292 = x

Divide by 292

x = 285.1 mL

The answer is D
