Answer:
a) the power consumption of the LEDs is 0.25 watt
b) the LEDs drew 0.0555 Amp current
Explanation:
Given the data in the question;
Three AAA Batteries;
<---- 1000mAh [ + -] 1.5 v ------1000mAh [ + -] 1.5 v --------1000mAh [ + -] 1.5 v------
so V_total = 3 × 1.5 = 4.5V
a) the power consumption of the LEDs
I_battery = 1000 mAh / 18hrs { for 18 hrs}
I_battery = 1/18 Amp { delivery by battery}
so consumption by led = I × V_total
we substitute
⇒ 1/18 × 4.5
P = 0.25 watt
Therefore the power consumption of the LEDs is 0.25 watt
b) How much current do the LEDs draw
I_Draw = I_battery = 1/18 Amp = 0.0555 Amp
Therefore the LEDs drew 0.0555 Amp current
Answer: A, B, C & F (interacting w computers, making decisions & solving problems, evaluating information & getting information).
Explanation: Those are the correct & verified answers.
Answer:
B. Acid rain.
C. Photochemical smog.
Explanation:
Oxides of nitrogen contribute to the formation of photochemical smog and acid rain. Photochemical smog is a type of smog produced when ultraviolet light from the sun reacts with nitrogen oxides in the atmosphere while on the other hand, when nitrogen oxide react with the water vapor in the atmosphere forming nitric acid which falls on the earth surface with the help of precipitation.
1. mechanical engineer, aircraft/space craft designer. Data processing manager. Military aerospace engineer. Inspector and compliance officer. Drafter. Aerospace technician. Mission or payload specialist.
2. ability to develop and conduct appropriate experimentation analyze and interpret data and ability to acquire in a play new knowledge is needed using appropriate learning strategies
3. Graduates of the co-op program are also up and offered a higher starting salary the co-op program for aerospace engineering students provides one full year of work experience divided into three segments of fall semester spring semester and a summer session
4. 4 years. no according to bachelors portal to join aerospace as an engineer or scientist you will have to study the subject for 4 to 7 years after high school
I think the correct answer is B
