Study this model of a gravitational slingshot. Then answer the questions. In this model, the velocity of the spacecraft at position 2 is the velocity of the craft at position 4. At position 1, the direction of the spacecraft changes because of . Position 3 represents the .

a small object of mass 3.66 g and charge -17.6 µc is suspended motionless above the ground when immersed in a uniform electric field perpendicular to the ground. what are the magnitude and direction of the electric field?

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.

f is prop to m1xm2 double m1 double force

the ima (higher than 1m) will be greater than the ima with the height of 1m.
