Explanation:
It is given that two loads have 0.75 Ampere current each. And, they contain 2500 milli ampere per hour Ni-Cd battery.
As both the loads are connected in parallel. Hence, total current will be calculated as follows.
I =
= 0.75 A + 0.75 A
= 1.5 A
=
= 1500 mA
Relation between time and capacity of battery is as follows.
Capacity = Current × time (in hour)
therefore, time =
=
= 1.667 hr
Thus, we can conclude that the battery provide power to the load up to 1.667 hours.
2 and 3 are not possible because energy cannot be created nor destroyed. In order to break bonds, energy must be absorbed, so 1 is your answer!
Molar mass is 28+32 = 60
So take 3.4 x 10^-7/60 and get about 5.7 x 10^-9
Petroleum, complex mixture of hydrocarbons that occur in Earth in liquid, gaseous, or solid form. Petroleum is a naturally occurring complex mixture made up predominantly of carbon and hydrogen compounds, but also frequently containing significant amounts of nitrogen, sulfur, and oxygen together with smaller amounts of nickel, vanadium, and other elements.
Hope this helps!
Answer:
C. 1 atm
Explanation:
More specifically it's .986 atm, but it's rounded up for this question.
