Answer:
the current is flowing to the left
the magnetic field is flowing out of the bottom of the screen
the screen and into the top of the screen.
Explanation:
6b: impulse is change in momentum. Change in momentum p=m[v(final)-v(initial). Final velocity is zero and initial velocity is the one you calculated before impact: -15.7 since it’s going down. Now plug in numbers and you get 78.5 in the upward direction.
6c: change in momentum p=Ft. we already calculated change in momentum. So plug it into equation and solve for t. 78.5/655= 0.119 s
Apply the same idea for question 7. Hope this helped
Answer:
A large elliptical
Explanation:
A S0 type galaxy is a large elliptical.
Answer:
Work = F * s where s is the distance F moves
Since F is stationary, in this case, "no work" is done by either person
Here ya go-!
Mass is both a property of a physical body and a measure of its resistance to acceleration (a change in its state of motion) when a net force is applied. An object's mass also determines the strength of its gravitational attraction to other bodies. The basic SI unit of mass is the kilogram (kg).
