It was once recorded that a Corvette left skid marks that were 38 m in length. Assuming that the Corvette skidded to a stop with a constant acceleration of 19 m/s 2from the brakes due to friction, determine the starting speed of the Corvette before it began to skid.

The passing of heat through a material while the material itself stays in place. a. radiation b. conduction c. convection

Select all of the following that are equal to an impulse of 20 unitsa) force= 5, time= 5.5b) force= 25, time= 0.8c) force= 0.1, time= 200d) force= 10, time= 2(its b, c, and d)(also in order to find answer they have to add to get the unit)ex= 25x.8=20 or .1x200=20

Electromagnetic induction. a coil of wire contains n turns and has an electrical resistance r. the radius of each turn is a. initially, inside the coil there exists a uniform magnetic field of magnitude b0 parallel to the axis of the coil. the magnetic field is then reduced slowly. the current induced in the coil is i. how long does it take for the magnitude of the uniform field to drop to zero?
