Answer: A Nucleus is present in both the plant and animal cell
Explanation:
Answer:
4 hours
Explanation:
Here we are given the battery capacity 80 kWh which is simply the power in watts ( or kilo-watts) multiplied by the time, and to obtain P.Now, we need to remember that Power is given by the Voltage times the current I. We have all these values, so lets answer the question:
P = V I = 250 V x 70 A = 17,500 watts = 17500 watts x 1 kW/1000 watts = 17.5 kW
Assuming 89 % efficiency means we will need 17.5/0.89 kW :
17500/ 0.89 KW = 19.66 kW
Then
t in hours = 80 kW h / 19.66 KW = 4 hours (rounding to the nearest hour)
These are structural formulas of constitutional isomers of hexene, an alkene.
Both are acyclic, six-carbon chains, and they differ only in the position of the double bond. As constitutional isomers, both structures have the same molecular formula.
The first structure is of hex-1-ene (or 1-hexene).
The second structure is of (3E)-hex-3-ene [or (3E)-3-hexene].
Both structures have the molecular formula C₆H₁₂.
I hope I answered your question. Please feel free to let me know otherwise.
Answer:
C
Explanation:
Because together all of the electrons create a negative charge.That balances the positive charge of the protons in the atomic nucleus.
