Explanation:
At maximum height, vertical velocity = 0 momentarily, but acceleration = g downward throughout motion. Memory tip: 'Peak: v=0, a=g; gravity never switches off'. Kinematics concept frequently tested to correct misconception that acceleration vanishes at peak.
Explanation:
Microwaves (2.45 GHz) are absorbed by water, fat, sugar molecules, causing them to rotate and generate heat through dielectric heating. Not induction (metal). Not conventional convection.
