Answer:

Explanation:
We have,
The surface temperature of the star is 60,000 K
It is required to find the wavelength of a star that radiated greatest amount of energy. Wein's displacement law gives the relation between wavelength and temperature such that :

Here,
= wavelength

So, the wavelength of the star is
.
Pretty sure it’s false....................
1) 4min = 4*60 sec = 240 sec
2) Distance = speed times time = 3 * 240 = 720 m
Answer:A
Explanation:
Since the bucket of water is constantly in motion it implies a force must be acting on it which allows it to change its Position constantly.
A constant gravity Force must be acting on water . In addition to gravity force a centripetal force must be acting on the water inside the bucket.
Bucket must move with certain velocity in order to avoid spilling of water.
