To solve this question you need to find the time span of the ski jumper before he lands
thus
25 = 1/2*10*t^2
50/10 = t^2
t = 2.23 seconds
and the distance is given 135m
speed = distance/time
= 135/2.23
= 60.5 m/s
#1). First of all, the 220 volts has to be changed to something near 110 volts. The most convenient way to do that is with a 2:1 step-down transformer. Those are readily available, for exactly this purpose, in kits of "travelers' accessories".
#2). Since Steve's immediate concern is his alarm clock, there's another important detail that he needs to consider. The power from the electrical outlets in the US is supplied at 60Hz, whereas the power in most of the rest of the world comes out at 50Hz. Many clocks use the frequency of the power outlet to keep time. If his 110V alarm clock is one of those and is designed for 60Hz, then if it's run on 50Hz power, it'll lose 10minutes of time every hour !
Steve's easiest and most economical solution might simply be to buy an alarm clock when he lands in New Zealand.
When two people come in contact or when contact occurs with an item from the crime scene, the possibility exists that a fiber transfer will take place. This does not mean that a fiber transfer will always take place. Certain types of fabric do not shed well (donor garments), and some fabrics do not hold fibers well (recipient garments). The construction and fiber composition of the fabric, the duration and force of contact, and the condition of the garment with regard to damage are important considerations.
Hope this helps.
I haven't worked on Part-A, and I don't happen to know the magnitude of the gravitational force that the Sun exerts on the Earth.
But whatever it is, it's exactly, precisely, identical, the same, and equal to the magnitude of the gravitational force that the Earth exerts on the Sun.
I think that's the THIRD choice here, but I'm not sure of that either.
