Assuming motion is on a straight path, the result of two positive components of a vector would also be a positive value since both are having positive signs and directions. The direction would be the same with the motion as well. Hope this answers the question. Have a nice day.

Answer:

The acceleration of the car will be $a=9600m/sec^$

Explanation:

We have given that distance from stop sign s = 200 m

Time t = 0.2 sec

We have to find the constant acceleration

Now from second equation of motion $s=ut+\frac{1}{2}at^2$

$200=40\times 0.2+\frac{1}{2}\times a\times 0.2^2$

$a=9600m/sec^$

So the acceleration of the car will be $a=9600m/sec^$

Which two options describe physical properties of matter?

Artyom0805 [142]

Answer:

A and E.

Explanation:

Physical properties have to do with things that are not done chemically.

A has to do with light that you can see.

B has to do with Ph (If not A this is your next answer)

C mentions a Patina which is a chemical reaction known as oxidation

D has to do with chemical reactions

E is always correct. One of the fundamental laws about matter is that it must always have mass.

I am 99% confident in A and E as your answer, but if it is wrong go with B and E.

Hope this helps!

Luda [366]

The characteristics shared by both heating and cooling curves is that phases changes when the temperature stays the same.

<h3>What is heating and cooling?</h3>

Heating is the process by which the temperature of a place or substances or object is increased.

Cooling Is the process of lowering the temperature of a substance or object by using conditioners or by freezing .

Therefore, The characteristics shared by both heating and cooling curves is that phases changes when the temperature stays the same.
