For a constant voltage, how is the resistance related to the current?

a) resistance is inversely proportional to the current, so when the resistance doubles the current is cut in half
b) resistance is directly proportional to current, so when resistance doubles the current cuts in half
c) resistance is inversely proportional to the current so when resistance doubles the current doubles.
d) resistance is directly proportional to the current so when the resistance doubles, the current doubles.

Convection currents are caused by differences in what two things?

A1000-kg car is moving at 30 m/s around a horizontal unbanked curve whose diameter is 0.20 km. what is the magnitude of the friction force required to keep the car from sliding?

Which of the following statements comparing electron microscopy and light microscopy is false? which of the following statements comparing electron microscopy and light microscopy is false? both the electron microscope and the light microscope use the same wavelengths for illumination. images produced by light microscopes can be in color, whereas electron microscope images are black and white unless they are artificially colored. the electron microscope has greater resolution than the light microscope. electron microscopes can allow examination of viruses and internal cell structures, whereas light microscopes are limited to objects that are 0.5 micrometers and larger. request answer
