Angular acceleration is given by
integrating both sides we will have
now if final angular speed is again ZERO
So it will be at rest after 5.23 s
Answer:
The weight of a 100 kg person on Earth is 100 N. This is because mass and weight are the same and do not change. On the Sun the person would weight 28 times more so you would multiply 100 N x 28 = 2, 800 N. The weight of a 100 kg person on Earth is 10.2 N.
Explanation:
but on the sun it would be zero because they would be burned to a chrip also
Answer:
d.none
Explanation:
because shape size and physical actually do are dependant
Answer:
6.54 × 10⁻⁵ Pa-s
Explanation:
Since the shear force, F = μAu/y where μ = viscosity of fluid between plates, A = area of plates, u = velocity of fluid = 0.6 m/s and y = separation of plates = 0.02 mm = 2 × 10⁻⁵ m
Since F = μAu/y
F/A = μu/y where F/A = force per unit area
Since we are given force per unit area, F/A = 1.962 N per unit area = 1.962 N/m²
So, μ = F/A ÷ u/y
substituting the values of the variables into the equation, we have
μ = F/A ÷ u/y
μ = 1.962 N/m² ÷ 0.6 m/s/2 × 10⁻⁵ m
μ = 1.962 N/m² ÷ 0.3 × 10⁵ /s
μ = 6.54 × 10⁻⁵ Ns/m²
μ = 6.54 × 10⁻⁵ Pa-s
