Answer:
tan theta = -18 / 25 = -35.8 deg
This direction is south of east
Answer:
ω₂=1.20
Explanation:
Given that
mass of the turn table ,M= 15 kg
mass of the ice ,m= 9 kg
radius ,r= 25 cm
Initial angular speed ,ω₁ = 0.75 rad/s
Initial mass moment of inertia
Final mass moment of inertia
Lets take final speed of the turn table after ice evaporated =ω₂ rad/s
Now by conservation angular momentum
I₁ ω₁ =ω₂ I₂
ω₂=1.20
Answer: D. wealthy
Explanation: on the e2020 test its right
Answer:
∴ [T]=[WF−1V−1]
Hope this answer is right!!
