6 0

I believe the answer is POTENTIAL ENERGY. The water at the top of the waterfall has Potential Energy. Potential Energy is defined as the energy that is stored when an object is at rest. At the top of the waterfall, water will have maximum potential energy. When the water falls down, it is will already have kinetic energy which is energy that is produced through continuous motion. When it is finally in the bottom, water will have maximum kinetic energy. <span> </span>

Answer:

4.99 mg of vitamin C are in the beaker.

Explanation:

Given that,

Weight of vitamin = 0.0499 g

Molar mass = 176.124 g/mol

Weight of water = 100.0 ml

We need to calculate the mg of vitamin C in the beaker

We dissolve 0.0499 g vitamin C in water to from 100.0 ml solution.

100 ml solution contain 49.9 mg vitamin C

Now, we take 10 ml of this vitamin C solution in breaker

Since, 100 ml solution =49.9 mg vitamin C

Therefore,

$10\ ml\ solution =\dfrac{10\times49.9}{100}$

$10\ ml\ solution =4.99\ mg$

Hence, 4.99 mg of vitamin C are in the beaker.

F = G m1*m2 / r^2 => [G] = [F]*[r]^2 /([m1]*[m2]) = N * m^2 / kg^2

That is one answer.

Also, you can use the fact that N = kg*m/s^2

[G] = kg * m / s^2 * m^2 / kg^2 = m^3 /(s^2 * kg)

It took a bulldozer 62,000 J of work to move a rock 30 m. It took 5 minutes. How much force did the bulldozer have to apply?

NeX [460]

Answer:

A (2066,6 N)

Explanation:

Use the Work formula

62.000J = F . 30

62.000/30 = 2066,6 N

The amout of time it took to move the rock doesn´t matter at all.

It is called a distraction variable, We don´t need it to solve the problem it is there just to confuse.
