Explanation:
The idea here is that you need to use the Periodic Table of elements to find the mass number of the most common isotope of phosphorus, P.
The answer is 4 Newton
force = mass x acceleration
F= 2 kg x 2.0 <span>m<span>s2</span></span>
= 4 Newton
Answer:
21.1cm or 10.1cm
Explanation:
Since the percent error is 35.5% and the experimental measurement was 15.6cm, the two possible values for the actual measurement are 15.6 plus 35.5% of 15.6 or 15.6 minus 35.5% of 15.6.
This is this:
15.6 + (0.355 x 15.6)
= 15.6 + 5.54
= 21.1cm
Or this:
15.6 - (0.355 x 15.6)
= 15.6 - 5.54
= 10.1cm
The scientist should make a new hypothesis and do a new experiment! That is what I say!
The nervous system sends signals to the muscles to shiver when our body temperature begins to drop to a lower than normal temperature. the slight movement of the muscles will work to bring temperature back to homeostasis
