A wave is moving towards shore with a velocity of 5.0 MS if it’s frequency is 2.5 Herz what is the wave length
EastWind [94]

Answer:

<h2>2 m</h2>

Explanation:

The wavelength of a wave can be found by using the formula

\lambda =  \frac{c}{f}  \\

where

c is the speed of the wave

f is the frequency

From the question

c = 5 m/s

f = 2.5 Hz

We have

\lambda =  \frac{5}{2.5}  = 2 \\

We have the final answer as

<h3>2 m </h3>

Hope this helps you

Pepsi [2]

Answer:

Mass of HCl = 73 g

Explanation:

Given data:

Mass of hydrogen = 2 g

Mass of HCl = ?

Solution:

First of all we will write the balance chemical equation:

H₂ + Cl₂   →  2HCl

Number of moles of hydrogen = 2 g/ 2g/mol

Number of moles of hydrogen = 1 mol

Form balanced chemical equation compare the moles hydrogen with HCl.

                   H₂    :   HCl

                    1      :    2

Mass of HCl:

Mass of HCl = number of moles × molar mass

Mass of HCl = 2 mol × 36.5 g/mol

Mass of HCl = 73 g

Process manufacturing, a class of manufacturing which is associated with the formulas and the manufacturing of recipes. This type of manufacturing is different from discrete manufacturing as it deals with discrete units and assembly of the components.

<u> This type of manufacturing is common in food, chemical, beverage,  nutraceutical, pharmaceutical, cannabis, and mostly biotechnology industries. In this manufacturing, the relevant factors are the ingredients and the bulk materials rather than the individual units. </u>

<u>Thus, formation of ice is an example of process manufacturing in which different ingredients are added and using recipe of freezing.</u>
