Lyon pulls on a 50. kg a wagon with a constant force of 340 N. Neglecting friction, the wagons acceleration will be (2 points) a 8.6 m/s2
b 7.4 m/s2
c 6.8 m/s2
d 6.6 m/s2
e 3.4 m/s2

What is the weight of a feather (mass = 0.0001 kg) that floats through earth's and the moon's atmospheres?

Aloop of wire is in a magnetic field such that its axis is parallel with the field direction. which of the following would result in an induced emf in the loop? choose all that apply. a loop of wire is in a magnetic field such that its axis is parallel with the field direction. which of the following would result in an induced emf in the loop? choose all that apply. moving the loop outside of the magnetic field region. spin the loop such that its axis does not consistently line up with the magnetic field direction. change the magnitude of the magnetic field. change the diameter of the loop

You are driving to the grocery store at 20 m/s. you are 110m from an intersection when the traffic light turns red. assume that your reaction time is 0.50s and that your car brakes with constant acceleration. how far are you from the intersection when you begin to apply the brakes? what acceleration will bring you to rest right at the intersection? how long does it take you to stop after the light changes? the known values: vi=20m/s xi=110m t=.50s vf=0m/s xf=0m a=?
