Troposphere is the answer
Room that wont bother other people... instruments a stereo, and a sound system
Answer:
20 watts
Explanation:
Big brain mode activated:
Power=1200J/60sec
Power=20 watts
0.4823 m/s
The initial velocity u1 of the ball=0
From the law of conservation of linear momentum.
m1u1+m2u2=m1v1+m2v2
(160×0)+(170×u1)=(160×0.3)+(170×0.2)
u1=0.4823m/s
Answer:
True
Explanation:
Let us consider a rigid body which contains tiny particles of mass dm each. and the angular velocity ω for each of the particle is same and teh radius of rotation is r.
the linear velocity, v = r ω
The total kinetic energy is given by



K = 1/2 Iω^2
where I is the moment of inertia.
