What do you make when you dissolve sugar in water?

1 answer:

5 0

It also takes energy to break the hydrogen bonds in water that must be disrupted to insert one of these sucrose molecules into solution. Sugar dissolves in water because energy is given off when the slightly polar sucrose molecules form intermolecular bonds with the polar water molecules.

I hope this helped :)

Two identical food packets were dropped from a helicopter. The first food packet was dropped from a height of 1,681 feet and the

Kazeer [188]

Answer:

The y intercept of the H2 is greater than H1.

Explanation:

Given,

The height from which the first food packet dropped = 1681 feet

The height from which the second food packet dropped = 961 feet

To find :

Two height functions and to compare in graph?

solution:

$h1(t) = -16t^2 + 1681$ is a vertical translation of $h2(t) = -16t^2 + 961.$

The y-intercept of h2 is 720 ft less than that of h1.

$h1(t) = -4t^2 + 41$ is a vertical translation of $h2(t) = -4t^2 + 31$ .

The y-intercept of h2 is 10 ft greater than that of h1.

$h1(t) = -16t^2 + 1681$ is a vertical translation of $h2(t) = -16t^2 + 961.$

The y-intercept of h2 is 720 ft greater than that of h1.

$h1(t) = -4t^2 + 41$ is a vertical translation of $h2(t) = -16t^2 + 31$ .

The y-intercept of h2 is 10 ft less than that of h1.

What produces the wavy effect in air over a hot stove

AysviL [449]

<span>The reason that things look wavy in the heat over a hot grill or stove is that the air temperature is not stable. Hot air naturally rises, so as air comes off the hot surface, it rises for a bit before rapidly cooling and sinking to be heated again. This constant mixing of hot and cool air produces vibration. This vibration affects how we see the light moving through the air, making it look wavy.</span>
