The number 4 represents four atoms of iodine per molecule. Thyroxine is a type of hormone produced by the thyroid gland and this hormone controls human's metabolism process. There are two hormones produced by the thyroid gland, the thyroxine and the triiodothyronine, which also control human's metabolism process. These hormones consisted of iodine atoms in each of the molecule, which human gets from eating salt.
Answer: 
Explanation:
The acceleration of an object can be calculated by using Newton's second law:

where
F is the net force applied on the object
m is the mass of the object
a is its acceleration
In this problem, we have F=125 N and m=25.0 kg, so we can rearrange the equation to calculate the acceleration:

Answer:
<em><u>0</u></em><em><u>.</u></em><em><u>9</u></em><em><u>1</u></em>
Explanation:
as equivalence resistance can be found out using the
1/Req = 1/r1 +1/r2 +1/r3......
now, 1/req= 1/2+1/3+1/4
=6/12+4/12+3/12
=13/12
i.e, req =12/13 =0.91

This is the information I can provide. I hope it helps
Explanation:
Frequency is measured in units of hertz (Hz) which is equal to one occurrence of a repeating event per second. The period is the duration of time of one cycle in a repeating event, so the period is the reciprocal of the frequency.
