The answer for this problem is clarified through this, the
system is absorbing (+). And now see that it uses that the SURROUNDINGS are
doing 84 KJ of work. Any time a system is overshadowing work done on it by the
surroundings the sign will be +. So it's just 12.4 KJ + 4.2 = 16.6 KJ.
Let's say the Moon's complete cycle of phases is about 28 days (4 weeks) ... just so the arithmetic is easier. (Close enough. It's actually 29.53 days.)
If it's halfway through the waxing crescent, then it'll reach first quarter in 3 days or so.
From there, it'll take the next 7 days to become Full, and another 7 days to reach last quarter.
Total from half-waxing-crescent to last quarter . . . about 17 days.
Answer:

Explanation:
As we know that when astronaut is revolving in circular path then the acceleration of the astronaut is due to centripetal acceleration
so it is given as

here we know that

also we know that

now we have


Answer:
Acceleration will be 
So option (D) will be correct answer
Explanation:
We have given angular speed of the electrical motor 
We have to change this angular speed in rad/sec for further calculation
So 
Armature radius is given r = 7.165 cm = 0.07165 m
We have to find the acceleration of edge of motor
Acceleration is given by 
So acceleration will be 
So option (D) will be correct answer
