Answer:

The answer to the question is

The wave speed is 53.57 cm/s

Explanation:

The speed of a wave is the distance covered by the wave per unit time.

Wave speed is given by

v = f×λ

where v = The velocity of the wave

f = The wave frequency

λ = The wavelength of the wave

the speed v of the wave can also be expressed interms of the period as

v = λ/T

The freuency of the given wave is f = 5/(0.112 s) = 44.64 Hz and the wavelength is λ = 1.20 cm

Therefore the speed of the wave = 44.64 Hz × 1.20 cm = 53.57 cm/s

<h3>What is the oxidation number of oxygen in H2O?</h3>

Oxygen almost always has an oxidation number of -2, except in peroxides (H 2 O 2) where it is -1 and in compounds with fluorine (OF 2) where it is +2. Hydrogen has an oxidation number of +1 when combined with non-metals, but it has an oxidation number of -1 when combined with metals.

A package contains 1.33 lb of ground round. If it contains 29% fat, how many grams of fat are in the ground round? The book is s
Effectus [21]

Answer:

To obtain the grams of fat that the ground round has, knowing that it weighs 1.33 pounds we must pass this value to grams. Since 1 pound equals 453.59 grams, 1.33 pounds equals 603.27 (453.59 x 1.33).

Now, to obtain 29 percent of 603.27, we must make the following calculation: 603.27 / 100 x 29, which gives a total of 174.94 grams.

In this way, your reasoning is correct and it is probably a mistake in the book.
