Answer:
B. closed series circuit because the resistors are one after the other and there is no open switch.
Explanation:
1c. The goal of technology is to improve how people live. For example a toothbrush helps prevent cavities and buildup on our teeth.
2a. Science and technology both help improve our lives. Science gives us the knowledge we need to create technology.
2b. A human prosthetic is an example of technology.
2c. Prosthetics are created though scientific study and research. Technology is used to create the material prosthetics are made of and to help design the prosthetics.
3a. Benefits of pesticides: Keeps bugs away from crops, higher crop yields.
Negatives:
pollution, harmful to health
I got all of them except the last one
Answer:
speed
Explanation:
its the speed
because the formula for deriving speed is distance/time
the unit for distance is metre
the unit for time is seconds
so speed is metre/seconds
so speed us m/s.
Answer:
μN/ (kg ns) = 10³ N / (kg s)
Explanation:
In this exercise they ask us if the notation is correct. Let's write the different terms in the SI systems
force is N
time is in seconds
the unit given for the force is 1 N = 10⁶ μN
the unit of time is 1 s = 10⁹ ns
the correct way to give the answer should be: N / (kg s)
so the notation should be changed
μN /kg ns = μN / (kg ns) (1N / 10⁶ μN) (10⁹ ns / 1 s) =
μN/ (kg ns) = 10³ N / (kg s)
