Because heat increases energy of the particles, making them move faster, thus making them collide faster...which makes it mix quicker and more efficiently

Answer:

Explanation:

The increase in temperature associated with heat increases the rate at which the hot chocolate dissolves.

This heat breaks apart the molecules holding the powder at a rapid rate compared to that of a cold water which is much slower.

Why do you think the United States government was formed as a republic, rather than as a direct democracy?
Fynjy0 [20]

Answer:

The United States is not a direct democracy, in the sense of a country in which laws (and other government decisions) are made predominantly by majority vote.

Explanation:

Some lawmaking is done this way, on the state and local levels, but it’s only a tiny fraction of all lawmaking. But we are a representative democracy, which is a form of democracy.

The United States is also a constitutional democracy, in which courts restrain in some measure the democratic will. And the United States is therefore also a constitutional republic.

As the price of gummy bears rises from $2. 60 to $3 , what are the price elasticities of demand of sugar-free gummy bears and of
NISA [10]

The price elasticities of demand of sugar-free gummy bears and of ordinary gummy bears is -0.8 and -2.3 respectively.

<h3>How to calculate price elasticity</h3>

Change in price of gummy bears = $2. 60 to $3

Elasticity of demand of sugar-free gummy bears =

[(273-379 / (273+379)/2] ÷ [(3.00-2.60)/(3.00+2.60) / 2]

= [-18/166] / [0.4/2.8]

= -0.10843373493975 / 0.14285714285714

= - 0.75903614457826

Approximately, -0.8

Elasticity of demand of regular gummy bears:

Sugar free = [(273-379) / (273+379)/2] ÷ (3.00 +2.60) / 2]

= [-106/326] / [0.4/2.8]

= -0.32515337423312 / 0.14285714285714

= -2.2760736196318

Approximately, -2.3
