If iron (Fe) has an atomic mass of 56 amu, oxygen (O) has an atomic mass of 16 amu, and hydrogen (H) has a mass of 1 amu, the atomic mass of Fe(OH)3 would be 107amu (option B).
<h3>What is atomic mass?</h3>
Atomic mass is the average mass of atoms of an element. The mass number of a compound can be calculated by summing the atomic masses of each element in the compound.
According to this question, the periodic table reveals that iron (Fe) has an atomic mass of 56 amu, oxygen (O) has an atomic mass of 16 amu, and hydrogen (H) has a mass of 1 amu.
The atomic mass of Fe(OH)3 can be calculated as follows:
= 56 + (16 + 1)3
= 56 + 51
= 107amu
Therefore, if iron (Fe) has an atomic mass of 56 amu, oxygen (O) has an atomic mass of 16 amu, and hydrogen (H) has a mass of 1 amu, the atomic mass of Fe(OH)3 would be 107amu.

I = 4.50 amps
R = 6.20 ohms
V = ???
V = I * R
V = 4.5 * 6.2
V = 27.9 volts.
Answer:
Angular acceleration = -1.57 Rad/s^2
Number of revolutions = 800 revolutions
Explanation:
Mass = 1.15kg
diameter of the grinding wheel = 22.0cm
angular speed = 20 rev/s
1 Rev/s = 6.283 rad/s
20 Rev/s = 20 * 6.283 = 125.664 rad/s
Angular acceleration = Angular speed/ time taken for for the wheel rotation
Angular accleration = 125.664/80
Angular acceleration = -1.57 rad/s^2 (since the wheel is rotating counterclockwise)
number of revs = 0.5∝t²
number of revs = 0.5 * (1.57/2π) * 80²
number of revs = 800 revolutions
Answer:
True
Explanation:
It is possible to reduce/lessen the force that is acting on an object. For example, if you were pushing on a box and wanted to push less on the box, that would be possible.
