Why do you think Kool Aid comes in packets that has a very finely ground powder (finely ground means very small particles)?

Kool-Aid is usually sold in powder form, in either packets or small tubs. The actual beverage is prepared by mixing the powder with sugar (the packets of powder are usually, though not always, unsweetened) and water, typically by the pitcherful. The drink is usually either served with ice or refrigerated and served chilled. Additionally, there are some sugar-free varieties.

Dissolving pretty well anything which is not itself going to boil or evaporate will increase the boiling point. So sugar, salt, Kool-Aid, all will elevate the boiling point of water.

Elevation of boiling point of a solution is one of several “colligative properties”, as we were told to call them in O-level chemistry. These are properties of a solution that change according to how many particles of solute are dissolved.

What force does a trampoline have to apply to a gymnast to accelerate her straight up at ? Note that the answer is independent o
Andrew [12]

Answer: Force applied by trampoline = 778.5 N

<em>Note: The question is incomplete.</em>

<em>The complete question is : What force does a trampoline have to apply to a 45.0 kg gymnast to accelerate her straight up at 7.50 m/s^2? note that the answer is independent of the velocity of the gymnast. She can be moving either up or down or be stationary. </em>

Explanation:

The total required the trampoline by the trampoline = net force accelerating the gymnast upwards + force of gravity on her.

= (m * a) + (m * g)

= m ( a + g)

= 45 kg ( 7.50 *  9.80) m/s²

Force applied by trampoline = 778.5 N

A ball is dropped off the balcony of a hotel room and it takes 2.8s to fall to the ground . how high above the ground is the bal
RideAnS [48]

The height of the ball above the ground is 38.45 m

First we will calculate the velocity of the ball when it touch the ground by using first equation of motion

v=u+gt

v=0+9.81×2.8

v=27.468 m/s

now the height of the ground can be calculated by the formula

v=√2gh

27.468=√2×9.81×h

h=38.45 m
