Question 1

A wheel rotating about a fixed axis has an angular position given by θ = 3.0 − 2.0t3, where θ is measured in radians and t in seconds. What is the angular acceleration of the wheel at t = 2.0 s?

◦
−1.0 rad/s2

◦
−24 rad/s2

◦
−2.0 rad/s2

◦
−4.0 rad/s2

◦
−3.5 rad/s2


Question 2

A wheel rotating about a fixed axis with a constant angular acceleration of 2.0 rad/s2 turns through 2.4 revolutions during a 2.0-s time interval. What is the angular velocity at the end of this time interval?

◦
9.5 rad/s

◦
9.7 rad/s

◦
9.3 rad/s

◦
9.1 rad/s

◦
8.8 rad/s

Though Candida and Aspergillus species are the most common fungal pathogens causing invasive fungal disease in the immunocompromised, infections due to previously uncommon hyaline and dematiaceous filamentous fungi are occurring more often today. Rare fungal infections, once accurately diagnosed, may require surgical debridement, immunotherapy, and newer antifungals used singly or in combination with older antifungals, on a case-by-case basis.
