Answer: V r 2 = 3.6 V Explanation: There is a voltage divider equation for two resistors in series:
V r 2 = R 2 R 1 + R 2 V
Because you can, arbitrarily choose which resistor you designate as R 2 and the other as R 1 , you can use this to find the voltage across either resistor. In your case, you want to designate the 2 Ω resistor as R 2 :
V r 2 = 2 Ω 3 Ω + 2 Ω 9 V V r 2 = 3.6 V
Answer:
A scientific control is an experiment of observation's designed to minimize the effect of variables and the other's than the independent variable. This can increases the reliability of the results,and can often through a comparison between control measurements and the other measurements.
Explanation:
Answer: molecular size or weight of the agent.
Explanation: The smaller the size, the faster it can diffuse out and the greater the rate of diffusion.
