Answer:

a. Help accomplish a job

Explanation:

Energy is defined as the ability to do work. It is the ability to get a job done.

Where energy is deficient, no job or work can be done.

  • In a water behind a dam, potential energy is stored.
  • Potential energy is due to the position of a body.
  • A moving car has kinetic energy which the energy due the motion of a body.
  • Electrical energy is used to carry the currents in a circuit round about.

What is the frequency of light that has an energy of 1.8 x 10-15 J? 6.626 x 10-34 Js 2.7 x 1018 Hz 3.7 x 10-19 Hz 1.2 x 10-48 Hz
Ann [662]
In order to determine the frequency, we may use Planck's equation:

Energy = Planck's constant * frequency

Rearranging and substituting the values,

frequency = (1.8 x 10⁻¹⁵) / (6.63 x 10⁻³⁴)
f = 2.71 x 10¹⁸ Hz

The frequency of the light is 2.7 x 10¹⁸ Hz

Ima 5% glucose solution, how many grams of glucose would be present per 100mL
Sedaia [141]

Percentage Weight-in-volume is defined as the <em><u>number of grams of a solute in a 100 ml (milliliters) solution.</u></em>

<u />

<u>Percentage Weight-in-volume</u> can tell us about the <em>degree of concentration of a given solution.</em>

<em><u /></em>

The solute can be <em>crystalline or non-crystalline in nature.</em>

<em></em>

The <u>number of grams of glucose</u> present in a <u>5% glucose solution</u> is 5 grams.

  • This question is based on a Percentage Weight-in-volume. The formula states that:

a% of a glucose solution =<u> a grams of glucose in a 100 mL solution</u>

Hence, 5% glucose solution = 5 grams of glucose / 100 mL solution

Therefore, the <u>number of grams of glucose</u> present in a <u>5% glucose solution</u> is 5 grams.

This is not chemistry but

see it is a triangular prim on it's side
V=BH
are of base times height
the base is a triangle
height is 18.5

base=1/2bh
b=8.6
h=8.4
base=1/2(8.6)(8.4)
base=36.12

V=bh
V=36.12*18.5
V=668.22

round
V=668.2 ft^3
