Why is it dangerous to not have the right grade motor oil for the climate you drive in?Select all that apply. When temperature increases the viscosity of the oil also increases and does not flow fast enough through the engine. When temperature increases the viscosity of the oil decreases and flows too freely through the engine. When temperature decreases the viscosity of the oil also decreases and flows too freely through the engine. When temperature decreases the viscosity of the oil increases and does not flow fast enough through the engine.

Certain bacteria (such as aquaspirillum magnetotacticum) tend to swim toward the earth’s geographic north pole because they contain tiny particles, called magnetosomes, that are sensitive to a magnetic field. if a transmission line carrying 100 a is laid underwater, at what range of distances would the magnetic field from this line be great enough to interfere with the migration of these bacteria? (assume that a field less than 5% of the earth’s field would have little effect on the bacteria. take the earth’s field to be 5.0 * 10-5 t, and ignore the effects of the seawater.)
