Answer:
W'=125.44 N
Explanation:
The weight of a person on the surface of Earth is 784 N
Weight is given by :
W = mg
m is mass of the person and g is acceleration due to gravity on the surface of Earth (10 m/s²)

The acceleration due to gravity on the surface of Moon, g' = 1.6 m/s²
Weight of the person on the moon is :
W'=mg'

Hence, the person would weigh 125.44 N on the Moon.
60 dekameters is equal to 0.6 kilometers (km).
(There is no measurement abbreviated 'dkm')
This matter spread out around theuniverse with no structure. But each little bit of matter exerted the force of gravity on each other little bit. Gravity is the only type of force connected with <span>the Big Bang as it is a basic force that was to create our world in th way we can see and discover it today.</span>
Answer:
the final velocity of the two blocks is
the distance that A slides relative to B is
Explanation:
From the diagram below;
acceleration of A relative to B is : 
where
v = u + at

Making t the subject of the formula; we have:


which implies the distance that A slides relative to B.
The final velocities of the two blocks can be determined as follows:
v = u + at

Thus, the final velocity of the two blocks is
i think the answer is D.
heating surface water causes it to evaporate and enter the air as a gas.
