Sean, an astronaut stands on the edge of a lunar crater and throws a Frisbee™ horizontally with a velocity of 5.00 m/s. With no atmosphere on the moon the Frisbee ™ will not have any force of lift so it will “fly” like a stone. The floor of the crater is 77.0 m below the astronaut. What horizontal distance will the Frisbee™ travel before hitting the floor of the crater? (The acceleration of gravity on the moon is 1/6th that of the Earth).

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be

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.

hi there!

out of the two, (b) precision would be more reasonable.   however, both a and b could be pretty reasonable.

the answer is b, have negligible mass
