Its the first one: it supplies radiant energy
Control group in a scientific experiment is a group separated from the rest of the experiment, it is where the independent variable being tested cannot influence the results. It isolates the independent variable's effects on the experiment and can helps rule out alternative explanations of the experimental results.
Answer:
bounced back at oncoming waves
____________________________________________________
If the incoming wave strikes a barrier at a 90 degree angle, the wave energy is, in fact bouncing back at oncoming waves.

-- The parallel combination of 4Ω, 6Ω, and 10Ω is 1.935Ω .
-- The battery sees 1.935Ω in series with 2Ω. That's 3.935Ω .
-- The voltage across the 3 parallel resistors is (1.935/3.935)
of the total battery voltage. That's about 5.9 volts.
-- I = V/R .
The current in the 10Ω resistor is (5.9v/10Ω) = 0.59 Amp. (choice-a)
