A. 1/9
Explanation:
The gravitational force between two objects is given by
where
G is the gravitational constant
m1 and m2 are the two masses
r is the distance between the two masses
From the formula, we see that the magnitude of the force is inversely proportional to the square of the distance: therefore, if the distance is tripled (increased by a factor 3), the magnitude of the force changes by a factor
Asterism, a pattern of stars that is not a constellation. An asterism can be part of a constellation, such as the Big Dipper, which is in the constellation Ursa Major, and can even span across constellations, such as the Summer Triangle, which is formed by the three bright stars Deneb, Altair, and Vega.
<u>Answer:</u>
a) Height of cliff = 44.145 meter
b) 7.5 meter far from its base the diver hit the water.
<u>Explanation:</u>
We have equation of motion , 
, s is the displacement, u is the initial velocity, a is the acceleration and t is the time.
Diver's vertical motion:
Initial velocity = 0 m/s, acceleration = 9.8 
, we need to calculate displacement when time is 3 seconds.
So height of cliff = 44.145 meter.
b) Diver's horizontal motion:
Initial velocity = 2.5 m/s, acceleration = 0 , we need to calculate displacement when time is 3 seconds.
So 7.5 meter far from its base the diver hit the water.
Answer: 12 J
Explanation:
Work = force*displacement
Work= 3N*4m= 12 Joule
The answer in the first space provided is realistic whereas
the second space provided is fantastic. The correct answer would be letter B.
In realistic, it has many views in which the frame is the
window on the world whereas fantastic depicts imagination or remotes from
reality.
