Explanation:
1. Rt = 30/(1+3+6) = 30/10= 3 ohm
i = V/Rt = 15/3 = 5 A
2. Rt = 3+1+ (12×6)/(12+6)
= 4 + (72/18)
= 4+4 = 8 ohm
i = 12/(8+2)
= 12/10 = 1,2 A
Answer:
The one that holds it backward will experience a greater reaction force.
Explanation:
Newtons third law of motion states that in every action there is equal and opposite reaction. The action force of making the water leave the nozzle for the firefighter who holds the hose backwards is greater than that for the fire fighter holding it straight. The water requires a a greater momentum and force to make a u-turn before leaving the nozzle. Hence the reaction force for the hose held backwards is greater
That measure is known as "acceleration"
a = ΔV / t
Hope this helps!
Answer:
2.6 moles are present in the given number of atoms of zinc.
Explanation:
It is known that 1 mole of any element contains Avagadro's number of atoms. So
Then,
moles
As here it is given that there is 1.58 * atoms of Zinc, then the number of moles in these number of atoms will be
moles
Hence, there are 2.6 moles in 1.58 * 10^24 atoms of zinc
Answer: A
Reason: one of his contributions was the development of a hierarchical system of classification of nature. Linnaeus also provided us with a consistent way to name species called binomial nomenclature. (From Internet)
