According to navigation rules and regulations, you are expected to maintain a proper lookout by sight and hearing at all time. Concerning looking out, the law states that 'every vessel shall at all time maintain a proper look out by sight and hearing and as well as by all appropriate means available in order to avoid the risk of collision'.
To find the acceleration, we can use a kinematic equation (shown below).
vf = vi + a x t
80 = 30 + a(30)
50 = 30a
a = 5/3 = 1.67 m/s
Hope this helps! :)
Answer:
I think the answer is D
Explanation:
all things grow and develop
all things reproduce if they didnt then there'd no more life
not all things can move from place A to place B
The correct answer is (b) Jupiter has mass less than that of sun which cannot generate enough pressure which can start hydrogen fusion. Jupiter has similar composition as both are entirely made up of hydrogen and helium. They both differ in the core and mass. The mass of Jupiter is so small as compared that it would not be able to generate enough pressure to start hydrogen fusion. Jupiter's core is made of metallic hydrogen and the core of sun is so hot that the hydrogen splits into electrons and protons. This generates hydrogen fusion.
Thus, Sun a star and Jupiter is not a star.
