A 17.0 resistor and a 6.0 resistor are connected in series with a battery. The potential difference across the 6.0 resistor is m
tia_tia [17]

Answer:

V= 57.5 V

Explanation:

  • If the resistors are in the linear zone of operation, the potential difference across them, must obey Ohm's law:

        V = I*R

  • For the 6.0 Ω resistor, if the potential difference across it is 15 V, we can find the current flowing through it as follows:

       I = \frac{V}{R} = \frac{15 V}{6.0 \Omega} = 2.5 A

  • In a series circuit, the current is the same at any point of it, so the current through the battery is I = 2.5 A
  • The equivalent resistance of a series circuit is just the sum of the resistances, so, in this case, we can write the following equation:

      R_{eq} = R_{1} +R_{2} = 17.0 \Omega + 6.0 \Omega = 23.0 \Omega

  • Applying Ohm's Law to the equivalent resistance, we can find the potential difference through it, that must be equal to the potential difference across the battery, as follows:

        V = I* R_{eq}  = 2.5 A * 23.0 \Omega = 57.5 V

During meiosis maternal and paternal chromosomes that occur in a gamete line up and exchange segments in a process called crossi
sergiy2304 [10]

Explanation:

Crossing over is the swapping of genetic material that occurs in the germ line. During the formation of egg and sperm cells, also known as meiosis, paired chromosomes from each parent align so that similar DNA sequences from the paired chromosomes cross over one another.

How often do spring and neap tides occur
iragen [17]

Answer:

Without thought to the season, Spring tides happen [two times] every [lunar] month the whole year. When the Sun and the Moon are quadratic, Neap tides also happen two times during a month.

Here is a picture to help show you:

(With the Spring tide, the moon is toward the "left" or "right" of the Earth. With the Neap tide, the moon is "above" or "below/under" the Earth. It's kind of hard to explain).
