Answer: D

Explanation: If you compare the star spectrum to the calcium element you can see that the lines match unlike the other elements.

Look at each of the bottom three strips, one at a time.
First look at the Hydrogen strip.
Then look at the Helium strip.
Then look at the calcium strip.

Each time you come to a black line, hold your finger on it, and
check to see whether there's a black line in the same place in the
"Star spectrum" strip at the top.

When I did it, I found that the Hydrogen and Helium lines are NOT
in the Star spectrum, but the calcium lines ARE. See if you agree.

The primary of a step-up transformer is connected across the terminals of a standard wall socket, and resistor 1 with a resistan

alexira [117]

The turns ratio is the factor that determines voltage andcurrent. In order to have the same current across the resistorin the primary as the resistor in the secondary, then:--N(p) = Primary turnsN(s) = Secondary turnsR(2) = Primary resistorR(1) = Secondary resistor--R(2)/R(1) = N(p)/N(s)R(2) = R(1)*(N(p)/N(s))--If arbitrary values are plugged in, you will see that this step up transformer will require 2x the resistance required in the secondary, R(1), to obtain the same current. Thus R(2) will be 1/2 the value of R(1). This is due to the stepped up voltage in the secondary.
