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.

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me

i really dont know but i will try okay.

so i think u would just add all them up and get your answer..

use photo math tells u all the answers thats what i use
