The answer is C. Flammability because if you were to test flammability of an object, you would e making a chemical change to the object.

A chemical change is when you mix one or more substances to form a new one. A physical change is when you can apply something to a substance but it doesn't change the substance.

Changing the density, color, and mass of an object it doesn't change the type of substance that object is.

Changing the flammability of something changes the type of substance it is. Well, because its irreversable.

The correct answer is [C] Flammability

Best of Luck!

Hi i have homework can you help me
soldier1979 [14.2K]

Explanation:

The particle will be at rest when its velocity v(t) is equal to zero. Recall that the velocity is simply the derivative of the position x(t) with respect to time:

v(t) = \dfrac{dx}{dt}

Since x(t) = t^2 - 2t + 2

then

v(t) = \dfrac{d}{dt}(t^2 - 2t + 2) = 2t - 2 = 0

Solving for t, we find that the particle will be at rest at

t = 1\:\text{s}

a 5.00 × 105 kg rocket is accelerating straight up. Its engines produce 1.50 × 107 of thrust, and air resistance is 4.50 × 106 N
Angelina_Jolie [31]
This one is simple :)

use the equation F = ma and then re-arrange for a.

a = F / m

But there is a trick, so be careful. the question gives you wind resistance. Simply subtract the wind resistance from the thrust of the rocket to get the net force upward.

1.50 * 10^7N - 4.5 8 10^6N = 1.05 * 10^7N

So,

a =  \frac{F}{m} =  \frac{1.05*10^7N}{5.00*10^5kg}
