Answer:
mass= 60kg
velocity= 10m/s
momentum = mass × velocity
p=m×v
p= 60×10
p= 600kgm/s
Answer: B
Explanation:
The other options have nothing to do with the water apart from transporting it.
Answer:
Slipher developed spectrographic methods that allowed researchers to see a Doppler effect in the distances of what were then called “spiral nebula,” what we today call galaxies. Simply put, by measuring the longer wavelength red shift (objects moving away) and shorter wavelength blue shift (objects moving closer), Slipher demonstrated that the universe was not static.
Explanation:
Explanation:
According to the law of conservation of energy,
......... (1)
As we know that, P.E = mgh
and, K.E = 
Therefore, putting these values of P.E and K.E into equation (1) as follows.
Now, initial case is that its starts with 50.3 m/s at bottom.
P.E = m and PE = 0
And, as it reaches the height h,
P.E = mgh
So, K.E will be m
Hence, speed = 6 m/s
Answer: Mercury is closest to the Sun and receives more of the Sun's concentrated light.
