Question 4

A uniform circular disc of radius 0.5 m and mass 3 kg is rotating about its central axis with an angular velocity of 10 rad/s. If the radius is increased to 0.75 m without changing the mass distribution, what will be the new angular velocity? (Assume conservation of angular momentum)

Accepted Answer

A. 4.44 rad/s — Angular momentum L = Iω is conserved. For a disc, I = ½mr², so ω₂ = (I₁/I₂) * ω₁ = (r₁²/r₂²) * ω₁ = (0.5²/0.75²) * 10 ≈ 4.44 rad/s. Option A (4.44 rad/s) is correct. Option B (6.67 rad/s) results from using diameter instead of radius. Option C (10.00 rad/s) assumes no change. Option D (15.00 rad/s) is a miscalculation of the ratio.

Answer

B. 6.67 rad/s

Answer

C. 10.00 rad/s

Answer

D. 15.00 rad/s

A teacher regularly uses quick quizzes, observation during group work, and informal feedback sessions during a unit to help students understand where they are struggling and to adjust her teaching methods. This approach primarily exemplifies which type of assessment?

Accepted Answer

C. Formative assessment — Formative assessment is designed to monitor student learning during instruction and provide ongoing feedback that can be used by instructors to improve their teaching and by students to improve their learning. Quick quizzes, observation, and informal feedback are all characteristic tools for formative assessment, aiming for continuous improvement rather than final judgment. Summative assessment is given at the end, diagnostic is before instruction, and norm-referenced compares to a group.

Accepted Answer

B. Brittle nails, hair loss, and muscle wasting — Brittle nails, hair loss, and muscle wasting are common objective signs of chronic malnutrition, indicating deficiencies in essential vitamins, minerals, and protein. Normal skin turgor, moist mucous membranes, clear urine, and absence of edema typically suggest adequate hydration and nutritional status. Elevated blood pressure can have various causes and is not a direct sign of malnutrition.
