Well, right now and for the past few years, the space shuttles have been in museums, unable to fly.
When they did fly, no space shuttle ever went farther than about 0.15 PERCENT of the distance to the moon.
No space shuttle ever got anywhere near half way.

Answer:
C. has no effect on validity
Explanation:
Repeating your experiment has no effect on validity.
It doesn't matter how many times you repeat your experiment. You have to find the average outcome of each experiment you do.
Answer:
Heat transfer in the process is -19.6 kJ
Work done in the process is - 28 kJ
Explanation:
As we know that the process equation is given as
now we know that
now from above equation we have
now work done in this process is given as
here we know N = 1.1
so we have
Now we have
now we have
so we have
The wavelength of a wave of frequency 4 Hz and speed 2 m/s is 0.5 m.
Answer:
Explanation:
As we know that speed of a wave is directly proportional to the product of wavelength and frequency of the wave. If any two variables are known, then we can easily find the third parameter.
Like, in this case, the wavelength is not given, instead the frequency is given as 4 Hz and speed is given as 2 m/s, so the wavelength can be easily determined.
Speed = Wavelength × Frequency
Then Wavelength = speed/frequency
So, wavelength = 2/4=0.5 m
Thus, the wavelength of a wave of frequency 4 Hz and speed 2 m/s is 0.5 m.
