For this part, imagine that the string is wound around the center axle of a yo-yo; the axle radius is raxle, but the yo-yo casing has a radius rcasing≫raxle and moment of inertia i≫mr2axle. in the limit the moment of inertia of the yo-yo i→[infinity] and the mass m of the yo-yo remains finite, what magnitudes would you expect for the tension t in the vertical section of string and the downward acceleration a of the center of mass?

5 w for 1hr = 5x60x60 joules=300x60=3000x6=18,000j as total energy conversion. efficiency of bulb needed for radiant to thermal within 18000

2b2t

explanation:

2b2t

can be answered using momentum.

momentum = p

p1= mass1 * velocity1

p1 = p2

therefore

p1 = 6kg * 4m/s

p1 = 24kgm/s

p2=m2 * v2

24 kgm/s = 7kg * v2

v2 = 24 kgm/s / 7kg

v2= 3.42 m/s

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
