Answer:
44 Ohms
Explanation:
Use Ohm's law:
(Resistance) = (Voltage) / (Current)
(Resistance) = 88V / 2 A = 44 Ohms
Answer:
O has higher ionisation energy, Ca requires less energy, non metals have higher electronegativities, highly reactive metal will be best fit for group 1
Answer:

Explanation:
Use the Coulomb's law. According to it, the flux through entire sphere would be

where, q is the total charge enclosed in the sphere and
is the absolute permittivity.
Thus, the flux through the hemisphere would be half of it i.e.

Answer:
2292W
Explanation:
Use the formula for energy first:

Where E = Energy || D = Distance || M = Mass.
Solve that equation:
E = 5 * 5500 ==> 27500J
To find power, divide energy per time:
27500J / 12s =~ 2292W
