In the time that it takes a whiteboard marker of mass 12 grams to fall 1 meter down to the Earth of mass 6 × 10 kg, 24 (a) how far does the earth move up towards the whiteboard marker? Derive your answer from Newton’s laws, and state when you are using which law. (b) Given that the smallest scale we have measured to date is 0.00000000000000000001 meters = 10 -20 m, can we measure this distance from part (a) yet? (c) Therefore, is part (a) a scientific question? A “scientific question” has to be measurable or falsifiable “in principle” (not necessarily in practice according to current technology).

3. a) The amount of time it takes you to fall asleep is called
“sleep latency”. Sleep latency in adults is Normal with a standard
deviation of 3.5 minutes. Forty-nine healthy adults volunteered for
a sleep study, where their sleep was monitored for one night. The
volunteers had an average sleep latency of 17.1 minutes.

Question number 12
A manager wishes to see if the time (in minutes) it takes for
their workers to complete a certain task is faster if they are
wearing ear buds. A random sample of 20 workers' times
were collected before and after wearing ear buds. Test the claim
that the time to complete the task will be faster, i.e. meaning has
production increased, at a significance level of α = 0.01
For the context of this problem, μD =...

A pendulum has a length 1 m and a mass 1 kg. Assume Earth free
fall acceleration equal to 10 m/s^2. When the pendulum oscillates,
the maximal deflection angle is +/-1 degree.
1.Suppose the pendulum started losing energy at the rate 1% per
period. As a result, the energy of the pendulum drops according to
E(t)= E(t=0)*exp(-z*t). Let’s call z damping constant, it has units
1/sec.
a) Find Z
b) Sketch E(t) for the time span of a few hundred...

Block 1 of mass 0.200g grams slides to the right with a speed of
8.00m/s. The block undergoes an elastic collision with block 2,
which is stationary and attached to a spring with spring constant
1208.5 N/m. After the collision the block 2 oscillates with a
period of 0.140s and block 1 slides off the opposite end of the
surface. If h = 4.90 m what is the distance d that block 1 will
go?
