With another person on student A’s side. I’m sorry if I wasn’t able to help. Im trying my best from the information given. :)
It should be gown, mask, gloves, and then goggles!
Answer:
Circuit one will have more current than circuit two
Explanation:
I am assuming that you have to see which circuit has the greater current in this case. Well, this is the perfect example of Ohm's Law, which states the following -
V = IR,
where V = voltage / potential difference, I = current, and R = resistance
If one circuit has twice the voltage and half the resistance of the second circuit, as voltage is directly proportional to the resistance -
2V = I( 1 / 2R ),
4V = IR,
I = 4V / R
Whereas in the second circuit -
V = IR,
I = V / R
As you can note, voltage is directly proportional to the current ( I ) as well as the resistance. The only difference between the two formulas I = 4V / R, and I = V / R is the difference in the voltage. With the voltage being 4 times greater in the first circuit, and current is 4 times greater in the first circuit as well.
<u><em>Hence, circuit one will have more current than circuit two</em></u>
Answer:
a) Volume = 2/3 
r³
Volume = 2/3 × 22/7 × 14 × 14 × 14 = 5749.3 cm³
b) Total surface area = 3r²
Area = 3 × 22/7 × 14 × 14 = 1848 cm²
