ANSWER: Eardrum

EXPLANATION:

The vibrations from the eardrum set the ossicles into motion. The ossicles are actually tiny bones — the smallest in the human body. The three bones are named after their shapes: the malleus (hammer), incus (anvil) and stapes (stirrup). The ossicles further amplify the sound.

Aqueous hydrochloric acid HCl will react with solid sodium hydroxide NaOH to produce aqueous sodium chloride NaCl and liquid wat

Makovka662 [10]

Answer:

1.4 g H₂O

Explanation:

In a reaction, the reactants are usually not present in exact stoichiometric amounts, that is, in the proportions indicated by the balanced equation. Frequently a large excess of one reactant is supplied to ensure that the more expensive reactant is completely converted to the desired product. Consequently, some reactant will be left over at the end of the reaction. The reactant used up first in a reaction is called the limiting reagent, because the maximum amount of product formed depends on how much of this reactant was originally present. When this reactant is used up, no more product can be formed.

A pinball bangs against a bumper, giving the ball a speed of 4. 5 m/s. If the ball has a mass of 50.0 g, what is the ball’s kine

Daniel [21]

Answer:

K.E = 0.5 j

Explanation:

Given data:

Mass of ball = 50 g (50/1000 =0.05 kg)

Speed of ball = 4.5 m/s

K.E of ball = ?

Solution:

Formula:

K.E = 1/2 m.v²

Now we will put the values in formula

K.E = 1/2 (0.05 kg) (4.5 m/s)²

K.E = 1/2 (0.05 kg) 20.25 m²/s²

K.E = 1/2 (1.0 kg. m²/s²)

K.E = 0.5 kg. m²/s²

j = kg. m²/s²

K.E = 0.5 j
