\textsf{For an Isosceles prism of Angle A and} \textsf{Refractive index}\: \sf \mu ,\textsf{ it is found that }\textsf{the angle of minimum deviation }\sf{ \delta_m = A.}\textsf{Then which of the following is/are correct}

\textbf{[ Multiple choice ]}

\textsf{(a) At minimum deviation, the incident}\sf{ angle \: \:i_1 }\textsf{and the retracting angle} \sf{r_1}\textsf{ at the first retracting surface are} \textsf{related by }\sf{ r_1 = (i_1/2) }

\textsf{(b) For this prism, the retracting index}\sf{ \mu}\textsf{ and the angle of Prism A are related as}
\sf{ A = \dfrac{1}{2}cos^{-1}\bigg\{\dfrac{\mu}{2}\bigg\}}

\textsf{(c) For this prism, the emergent ray at the }\textsf{second surface will be tangential to the }\textsf{surface when the angle of incidence at the}\textsf{ first surface is}\: \sf{ i_1 = sin^{-1} \bigg[sinA \sqrt{4cos²\dfrac{A}{2}-1}-cosA\bigg]} [tex] \textsf{(d) For the angle of incidence}\sf{ i_1 = A,} \textsf{the ray}\textsf{ inside the prism is parallel to the base}\textsf{ of the prism}

A centrifuge in a medical research laboratory rotates at an angular speed of 3,650 rev/min. When switched off, it rotates 46.0 t
erma4kov [3.2K]

Answer:

The constant angular acceleration of the centrifuge = -252.84 rad/s²

Explanation:

We will be using the equations of motion for this calculation.

Although, the parameters of this equation of motion will be composed of the angular form of the normal parameters.

First of, we write the given parameters.

w₀ = initial angular velocity = 2πf₀

f₀ = 3650 rev/min = (3650/60) rev/s = 60.83 rev/s

w₀ = 2πf₀ = 2π × 60.83 = 382.38 rad/s

θ = 46 revs = 46 × 2π = 289.14 rad

w = final angular velocity = 0 rad/s (since the centrifuge come rest at the end)

α = ?

Just like v² = u² + 2ay

w² = w₀² + 2αθ

0 = 382.38² + [2α × (289.14)]

578.29α = -146,214.4644

α = (-146,214.4644/578.29)

α = - 252.84 rad/s²

Hope this Helps!!!

Ex 10: My dog runs at 6 m/s for 18 meters. How long did she run for?
Hunter-Best [27]
She ran for 3s

Put 18/6 because in order to find how long she ran for you need to divide the distance by the meters ran, once you do that you will get 3.
