Answer: Option (B) is the correct answer.

Explanation:

Reactants are the species which are present on the left hand side of a chemical equation.

On the other hand, products are the species which are present on the right hand side of a chemical equation.

For example, $NaCl + H_{2}O \rightarrow NaOH + HCl$

Here, NaCl and H_{2}O are the reactants whereas NaOH and HCl are the products.

This also means that products are the new substances which are formed.

Thus, we can conclude that new substances that are present at the end of a reaction accurately describes the products of a reaction.

Answer:

a) $f_{e}$ = 3,375 cm , b) f₀ = 77.625 cm

Explanation:

The magnification of a telescope is, to see at the far point of vision (infinity image)

m = - f₀ / $f_{e}$

The length of the tube is

L = f₀ + $f_{e}$

a) The focal length of the eyepiece

L = - m $f_{e}$ + $f_{e}$

L = $f_{e}$ (1-m)

$f_{e}$ = L / (1-m)

Let's calculate

$f_{e}$ = 81.0 / (1 - (-23.0)

$f_{e}$ = 3,375 cm

b) the focal length of the target

f₀ = -m $f_{e}$

f₀ = 23 (3.68)

f₀ = 77.625 cm

leva [86]

Answer:

Charge

Explanation:

Charge is a fundamental property of all matter. All matter has electrical and magnetic properties because the atoms that make up matter are held together by electromagnetic forces.

These charges are usually positive and negative charges. When these charges which make up an atom (positive and negative) are equal, the atom is said to be electrically neutral. When positive charge is greater than negative charge, the atom is said to positively charged. Also, if the number of negative charges are more in an atom, the atom is said to be negatively charged.
