Since the angular acceleration α is constant,
0² - (30 rev/s)² = 2α (60 rev)
Solve for α :
α = -(30 rev/s)²/(120 rev) = -7.5 rev/s²
One revolution corresponds to an angular displacement of 2π radians, so
α = (-7.5 rev/s²) × (2π rad/rev) ≈ -47.12 rad/s²
2 they are easy to compress,
2 they expand to fill their containers,
3 they occupy far more space than the liquids or solids from which they form.
hope this helped!
Answer:
Due to polarization of charges on either side the dielectric, it produces an electric field of its own which acts in a firection opposite to that of the field due to the source.
Answer:the force applied to the object
