A 2.19 kg block initially at rest is pulled to the right along a horizontal surface by a constant,
horizontal force of 16.1 N. The coefficient of
kinetic friction is 0.145.
The acceleration of gravity is 9.8 m/s
2.
Find the speed of the block after it has
moved 3.35 m.
Answer in units of m/s.

Which accurately compares concave and convex lenses?

Imagine that you have two balloons (or, better yet, actually inflate two balloons, if possible). create static electricity around one of the balloons by rubbing it against your hair or your sweater and then bring that balloon close to the other balloon, which has not been charged. try this with at least one other object—and for variety in the discussion, avoid using an object already described by your classmates. then, for your initial post to the discussion, answer the following questions: what happened with the two balloons?

6–48 bananas are to be cooled from 24 to 138c at a rate of 215 kg/h by a refrigeration system. the power input to the refrigerator is 1.4 kw. determine the rate of cooling, in kj/ min, and the cop of the refrigerator. the specific heat of banana above freezing is 3.35 kj/kg·8c.
