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).

If 1 grams of sodium bicarbonate are decomposed, determine the combined mass loss (in grams) of water and carbon dioxide that are produced. When a 1.08g mixture of sodium chloride and sodium bicarbonate were heated for several minutes in a crucible and the mass after the first 3 heating intervals remained 0.8 grams. What is the combined mass loss of water and carbon dioxide per gram on sodium bicarbonate?

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?
