What is the magnitude of the acceleration experienced by the tip of the 1.7cm long sweep second hand on your wrist watch?
You are supposed to use one of the formulae for acceleration in circular motion. Use one of the following:
a = v2/r, or:
a = omega2r
First you must convert everything to compatible units, for example meters, meters/second. Omega is the angular velocity and - if using SI units - should be converted to radians/second.

What is the second hand on a clock called?
Sometimes, it is called a sweep hand, but the hands on a clock usually are called hour, minute, and second.
How is the mass of an object related to the object acceleration?
As you make an object move (accelerate it) you are applying a force to it. Say that force was a sweep of your hand and there were two different sized bags of sugar. Taking the small bag first, as your hand hits it, it pushes the bag forwards a certain distance. The taking the second, larger bag and pushing that with the same force, the distance you will move it is less than for the smaller bag. The reason for the difference is that the larger bag contains more mass (more sugar) than the smaller bag. What doing this shows you is that it takes energy/force to move something and the more massive that something is, the more the force you need to apply. A famous British scientist called newton worked this all out and his equation to explain it is: Acceleration= Force/Mass
Is a broom an example of a second class lever?
Yes, a broom is an example of a second-class lever. In a second-class lever, the load is located between the fulcrum and the effort. When you push down on the handle of a broom to sweep, the load (dirt and debris) is located in between the fulcrum (floor) and the effort (your hand on the handle).
How fast does a spot of laser sweep across clouds of a turntable at the top of a mountain and turns 10 revolutions per second if it reaches clouds 10km away?
In km/ seconds: 10km=r= radius Circumference = 2(Pi)(r) = 20km(Pi) = 62.83185307 The laser is making 10 sweeps/ second so times the answer by ten. 200(Pi) km/sec or 628.3185307 km/sec *If you have to go by sig. figs. 600 km/sec. If you don;t know what sig. figs. are ignore this.
Where does the energy of a pulsar came from?
The energy of a pulsar comes from its rotation as it slows down, converting rotational energy into radiation and particle acceleration. Pulsars are rapidly rotating neutron stars, and as they slow down over time, they emit electromagnetic radiation in the form of beams that sweep across our line of sight.

What is difference in Alternate mode triggering and Chop mode triggering?
These are the 2 triggering modes available in a CRO. In alternate triggering mode, the first horizontal sweep is reserved for the first channel to output the waveform, the second sweep for the second channel and this keeps alternating. This is suitable when sweep time is small or else we may observe flickering of signals in the display [This is because, during a sweep, one of the channel is inactive and thus its output clears off in a certain time( remember phosphorescent coating)]. In chopped mode, during a sweep, parts of the output wave are drawn in both the channels in an alternating manner, the frequency of which is kept high to provide in-sensitiveness to human eye. This works well for higher sweep times.
