answer all for 50 points ANSWERS SHOULD BE CORRECT!!!

Answer 1

remains constant 2500 aur third fourth and fifth ka c option hai

Answer 2

Answer:

Explanation:

torque=moment of inertia*angular acceleration

w1=0=at rest

angular velocity=5=w2

t=2 s

w2=w1+at

5=2 a

a=2.5 m/s

torque=1000*2.5=2500 Nm

17)CENTER OF MASS=m1(r1)+m2(r2)+m3(r3)/m1+m1+m3

                                   =i+j+4i+10j+8i-4j/7

                                  =13i+7j/7

18)increases
