Two balloons have equal and opposite charges. Balloon one has N = 109 excess electrons. The balloons are separated by d = 2.7 m and each electron has a negative charge of e = 1.602 × 10-19 C. Part (a) What is the charge on balloon two, Q2, in C?
Kant realizes that most people do what is right based on their emotional states, such as, "it makes me feel good to help others" or "I would feel guilty if I didn't do the right thing." He also thinks that we should not base an ethical system on human feelings or emotions. According to Kant, what is the problem with basing ethics on human emotions? Check all that apply. Emotions are confusing, so we don't always know which is the right one we should act on. There are still righT and wrong things to do and people still have the ability to do what is right no matter how they feel. Some people have feelings for other human beings but lose them over time. Some people are born without feelings for other human beings.

A mechanical engineering student wishes to determine the internal pressure existing in a diet soda can. She proceeds by carefully mounting a single-element strain gage aligned in circumferential direction on the center of the soda can, as shown in Fig. 12.22 (below). After wiring the gage properly to a commercial strain indicator, she "pops" the flip-top lid, which relieves the internal pressure. She notes that the strain indicator reads -400E-6. If the can body is made of aluminum (E=$10^6$ psi) with a thickness of 0.010 in and a diameter of 2.25 in, what was the original pressure of the sealed can? Enter your answer in psi (e.g 120.1) QUESTION 6 Another student also performed the experiment described in the problem above. Unfortunately, he did not have access to the commercial strain indicator, and instead he had to construct his own Wheatstone Bridge circuit. His strain gage had an initial resistance of 120 Ohm and a gage factor of 2.05. He used the single gage as one leg of the bridge, which he powered with a 6-V battery. The bridge output was fed to an amplifier (gain = 1000), and the amp's output was read by a voltmeter. The student balanced the bridge circuit before he opened the can. After the can was opened, the voltmeter indicated a voltage of -1.57 V. What was the measured pressure for his can? Enter your answer in psi (e.g 120.1)

Ignore air friction for the following problem. If you throw a stone upwards with a speed greater than the escape speed, it will continue to move away from Earth forever and never return. The escape speed on Earth is 11.186 km/s. Now consider that you throw a stone directly in the direction of the Moon (it is ok to ignore the rotational motion of the Moon around the Earth). What is the minimum speed that you need to give the stone so that it makes it to the Moon? It is recommended to carefully think about this problem and then use energy conservation to find a solution. Even for the minimum speed the stone will have a large velocity when it reaches the Moon. You can use the following data: mass of Earth is $5.972 \times 10^{24}$ kg, mass of the Moon is $7.348 \times 10^{22}$ kg, distance Earth-to-Moon is $384.4 \times 10^6$ m, radius of Earth is $6.371 \times 10^6$ m. The solution requires at least 4 correct digits.
7. Consider the DNA segment ATGACGGTTTACTAAGCC a. Write the mRNA sequence that would be obtained from the segment's transcription.
I have just designed an Internet of Things system that will manage backyard gardens for GMU students who are at home during the pandemic. Here are some key features: • This is a custom, one processor, one core microcontroller running a simple embedded Operating System (OS) • Up to five programs will be executed simultaneously by the embedded OS. • These will let the device process sensor data, to update its own webpage, serve the webpage, adjust watering, and allow users to login to a shell to administer the other four programs. • This is a real-time system so watering will always happen on a set schedule, even if another process is running now, the OS will switch over to watering and resume the other process after it finishes. • This is a networked system that allows multiple users to connect and administer the device at the same time. Answer the following two questions in your statement below: 1. Is this a multiprogrammed system? Why or Why Not? 2. Is this a time-sharing system? Why or Why Not?
