Which of the following is NOT a proposed method of interstellar travel?
A. Bussard Ramjet
B. Interstellar fluid travel
C. Solar Sail
D. Warp Drive
Answer: C. solar sail
Explanation: hope I'm right if I'm wrong I'm sorry
Answer: C (Educated Guess, read about wind below)
Explanation:
It’s a guess, more so a presumption. A solar sail would require what a sail on earth does to make its main part move..... wind flow. Yet wind flow, aka convection, is caused by the sun warming air on different parts of the earth, increasing its pressure, pushing away cold air, creating wind. There isn’t any surface in space that the heat can build upon... not knowing anything about the other choices, this about choice C is enough to convince me that it is the one that is not effective.
ahmed is 4 years old than sara, 5 years ago the sum of their age was 48, write a equation to represent the situation and find saras age
Answer:
Sara is 27 years old and Ahmed is 31 years old.
Explanation:
Sara was 22 years old before.
Ahmed was 26 years old before.
5 years before= 5+5=10
So, minus five from both to make 10.
Now add five plus five to make 10 to find their current age by subtracting 4 years from Ahmed's age.
Answer:
Explanation:
sara=s
ahmed = s+4 (4 years older than Sara)
s-5 + (s+4)-5 = 48
2s -6 = 48
2s = 54
s=27
SARA is 27 AHMED is 31
5 years ago:
SARA WAS 22 AHMED WAS 26
22+26 =48
