a). F= m a
500 N = (m) (5.00 m/s^2)
m = 100 kg
b). Accelerating body covers distance of
D = 1/2 a T^2
D = 1/2 (5.00 m/s^2) (100 s)^2
D = 25,000 meters
Note: I'm pretty sure the acceleration is typed wrong in the question. If so, then these answers won't be correct.
Answer:
I dunno for sure but i think its C " reduced wear and tear".
Explanation:
I dont really have an explanation for it, it just kinda feels right. Ill update this with the actual answer when i submit the test.
Answer:
Explanation:
It is given that,
Wavelength of hydrogen line,
Shift in wavelength,
According to Relativistic Doppler Effect, the shift in wavelength is given by :
v is the speed of star
c is the speed of light
or
v = 91.43 km/s
So, the star is moving with a speed of about 100 km/s. Hence, this is the required solution.
Hydrogen.
When they run out of hydrogen fuels in its cores, fusion stops. The collapse of the core causes the temperature to increase in it and around it. Eventually the heat of collapse is enough for the shell of hydrogen are the core to fuse and it turns into a red star.
