Explanation

Angular acceleration is produced by torque.

Torque is the rotational equivalent of force.

And just as force causes linear acceleration, torque causes angular acceleration. 

Explanation

A thinner convex lens has a longer focal length because it bends light rays less sharply than a thicker convex lens.

A thicker convex lens has a shorter focal length as it bends light rays more strongly, bringing them to focus sooner.

The boiling point of water decreases at higher altitudes due to Low atmospheric pressure

The boiling point of water increases with increased atmospheric pressure

The boiling point of water decreases with decreased atmospheric pressure
