We must __________ forces to calculate net force if the forces are going in OPPOSITE directions.
Virty [35]

Answer:

subtract

Explanation:

To find the net force of two bodies going in opposite directions, we must subtract the forces this is because they are not additive forces.

  • The net force is the resultant force acting on a body.
  • This resultant force is the single force that will produce the same effects as all given forces.
  • When forces are directed oppositely on a body, they are subtracted from each other to find the net force.

What component of amino acid structure varies among different amino acids?
givi [52]

Answer

The components of the r group of amino acid structure varies among different amino acids

Explanation  

As the functional group for amino acids is as:  

R-CH-COOH  

 I  

NH2  

only R differs so amino acids also differs. If R is “H” then amino acid is glycine and if R is “CH3” then amino acid is alanine. Hence, R is different for different amino acids. Other components as alpha carbon ( C ), carboxyl group ( COOH ) and amino group ( NH2 ) is fixed for every amino acid.

Calculate the mass of 3.4 moles of nitrous acid (HNO2). Explain the process or show your work by including all values used to de
Zina [86]

Answer:

Mass = 159.8 g

Explanation:

Given data:

Mass of HNO₂ = ?

Moles of nitrous acid = 3.4 mol

Solution:

Formula:

Number of moles = mass / molar mass

We will rearrange this formula.

Mass = number of moles × molar mass

Molar mass of nitrous acid =  47 g/ mol

Mass = 3.4 mol × 47 g/ mol

Mass = 159.8 g
