Calculating probabilities in pedigrees of X-linked conditions
I understand this chapter for the most part, but I really can't solve this one question. Sorry, I couldn't get the question all in one screenshot so I had to use two! Thanks in advance for the help!
A group of students found an old DC electric motor in a box. They were looking for a small generator they could use to power their computer while they were out camping. Explain how they might do this with the motor they found.
Three 12 Ω resistors are connected in parallel and then connected to a 6.0 V battery. Find the resulting current. Show your work (formula, substitution, answer rounded correctly and with the appropriate unit. This is a two part question.
A cell phone battery has 9.00×10–3 kWh of energy stored in it. If the battery runs at 3.20 V and draws an average of 0.375 A of current, how long will the battery last? Show your work, including formulae and substitutions and express your answer
Using an old DC electric motor, how could this be used to power the computer

A 100 MW power station generates energy at 26.0 kV. The power lines must carry only 200 A of current to be efficient enough. To what voltage must the potential be increased? Show your work (formula, substitution, answer rounded corre
Electric transmission is accomplished at very high voltages when long distances are being covered. This reduces the currents involved and makes the transmission line far more efficient. On the other hand, we don’t want extremely high voltages in our
A desk top computer plugs into the wall socket at 120V and draws an average current of 2.10 A. How much energy (in kWh) does the computer use each day assuming that it is never turned off? Show your work, including formulae and substitutions and
A small Styrofoam ball has a 2.26 nC charge (2.26×10-9 C). Find the electric field strength 5.00 cm (0.0500 m) from the ball. Show your work (formula, substitution, and answer (rounded correctly and with the appropriate unit)) .
Mercury has a mass of 3.30×1023 kg and a radius of 2.44×106 m. Find Mercury’s gravitational field strength. Show your work (formula, substitution, and answer (rounded correctly and with the appropriate unit)) .
The M and N factors are glycoproteins that are found on the surface of red blood cells. Unlike other types of red blood cell antigens, The M and N factors do not cause antibody reactions in human blood transfusions. People with type M blood are homoz
