The Force Exerted on the Moon In Figure 5-37 we show the Earth, Moon, and Sun (not to scale) in their relative positions at the time when the Moon is in its third-quarter phase. Though few people realize it, the force exerted on the Moon by the Sun is actually greater than the force exerted on the Moon by the Earth In fact, the force exerted on the Moon by the Sun has a magnitude of F SM = 4.34 × 10 20 N , whereas the force exerted by the Earth has a magnitude of only F EM = 1.98 × 10 20 N. These forces are indicated to scale in Figure 5-37 . Find (a) the direction and (b) the magnitude of the net force acting on the Moon. (c) Given that the mass of the Moon is M M = 7.35 × 10 22 kg , find the magnitude of its acceleration at the time of the third-quarter phase. Figure 5-37 Problems 35

Though few people realize it, the force exerted on the Moon by the Sun is actually greater than the force exerted on the Moon by the Earth In fact, the force exerted on the Moon by the Sun has a magnitude of FSM = 4.34 × 1020N , whereas the force exerted by the Earth has a magnitude of only FEM = 1.98 × 1020N.

How can you tell which vowel is being produced here ( “ee,” “ah,” or “oo”)? Also, how would you be able to tell for the other vowels?
You want to fabricate a soft microfluidic chip like the one below. How would you go about
fabricating this chip knowing that you are targeting a channel with a square cross-sectional
profile of 200 μm by 200 μm. What materials and steps would you use and why? Disregard the
process to form the inlet and outlet.

1. What are the key steps involved in the fabrication of a semiconductor device.
2. You are hired by a chip manufacturing company, and you are asked to prepare a silicon wafer
with the pattern below. Describe the process you would use.
High Aspect
Ratio
Trenches
Undoped Si Wafer
P-doped Si
3. You would like to deposit material within a high aspect ratio trench. What approach would you
use and why?
4. A person is setting up a small clean room space to carry out an outreach activity to educate high
school students about patterning using photolithography. They obtained a positive photoresist, a
used spin coater, a high energy light lamp for exposure and ordered a plastic transparency mask
with a pattern on it to reduce cost. Upon trying this set up multiple times they find that the full
resist gets developed, and they are unable to transfer the pattern onto the resist. Help them
troubleshoot and find out why pattern of transfer has not been successful.
5. You are given a composite…
