Do you remember when there seem to be more stars in the sky? or maybe it's because I was younger. I remember when we could play into the night by the starlight. Has the atmosphere gotten this dirty? or what?

The electrons that produce the picture in a
TV set are accelerated by a very large electric
force as they pass through a small region in
the neck of the picture tube. This region is
1.7 cm in length, and the electrons enter with
a speed of 100000 m/s and leave with a speed
of 1.5 * 10^8 m/s.
What is their acceleration over this 1.7 cm
length? Answer in units of m/s2.

part 2
How long is the electron in the accelerating
region? Answer in units of s.

It is a beautiful shade tree but I'm at wits end in seeking a solution to my problem. A local tree nursery tells me that they don't have an answer. In winter, here in CA it drops blossoms,in spring fruit which contains tannic acid, and a brown stain. In summer we get seed pods all of which keep me very busy. Any proven ideas?

Consider a block on an incline plane. The co-
fficients of static and kinetic friction between
the block and the incline are us = 0.433 and
uk = 0.31. The block is 1 kg
Calculate the critical angle theta c, where the
block just begins to slide. Answer in units of
degrees.

part2
Determine the magnitude of the frictional
force f when theta < theta critical.
1. abs(f) = mg sin theta
2. jfj = uk mg cos theta
3. jfj = usmg sin theta
4. jfj = usmg cos theta
5. jfj = uk mg sin theta
6. jfj = mg cot theta
7. jfj = mg cos theta

part3
Determine the magnitude of the frictional
force f when theta > theta critical.
1. jfj = mg cos theta
2. jfj = uk mg sin theta
3. jfj = uk mg cos theta
4. jfj = usmg sin theta
5. jfj = mg cot theta
6. jfj = usmg cos theta
7.jfj = mgtan theta

my last question was can a girl bury a ten inch bone faster than a rottweiler can bury one,,,, how many girls accually got the joke and how many thought it meant they both make a hole in the ground and put a bone in the hole and how many hace accually burried a ten inch bone or there partner has a ten inch bone and they bury it in lots of places every night. i think this question has a lot to do with the answere to the meaning of life as we know it.
