Answer:
I don't know sorry hopefully I can help with something else tho
Resistance = (voltage) / (current)
Resistance = (100 V) / (20 A)
<em>Resistance = 5 Ω (D)</em>
Li2O
Lithium is a metal with an oxidation number of 1+ and oxygen is a nonmetal with an oxidation number of 2-. Which chemical formula represents the compound formed by these two elements? Li2O is the correct answer because lithium has one valence electron and oxygen has six.
Hope this helped.
<h3><u>Answer;</u></h3>
A. 4
<h3><u>Explanation;</u></h3>
- <em><u>The period of a wave or periodic time is the time taken for a complete oscillation to occur. </u></em>For example its is the time taken between two successive crests or troughs.
- <em><u>The beats or oscillation that occur in one second represents the frequency. Frequency is the number of complete oscillations or beats in one second in a wave.</u></em>
- Frequency, measured in Hertz is given by the reciprocal of the periodic time.
- Thus; <u><em>Frequency or beats per second = 1/(1/4) = 4</em></u>
- <u><em>Hence , 4 beats per second</em></u>
Answer:
10.6962 ml
Explanation:
the density of water is 1g/ml
if you devide the mass by density you get the volume the volume times density is equal to the mass so
84.5 grams devided by 7.9 is equal to 10.6962 ml.
if you do that times 1g/ml is equal to 10.6962 g/ml.
