Aboy fires a table tennis launcher. briefly describe the forces and impulses on the launcher and the ball. explain which has momentum. explain which is moving faster. be sure to use at least 3 to 4 complete content related sentences.

As we know by Newton's III law that if an action force is applied on an object then the reaction force of same magnitude in opposite direction will act on the other.

So here when ball is shot using launcher then the force will be same on launcher as well as ball so we can say

now since force is of same magnitude for both both then we will have

so from above we can say that both ball and launcher will have same impulse but opposite in direction.

Now since ball will have less mass so here it will have more speed while launcher is heavy in mass so its speed is slow or very small as comapre to ball.

answer: the direction of the wind is expressed as the direction from which the wind is blowing. for example, easterly winds blow from east to west, while westerly winds blow from west to east.

explanation:

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.
