Vertical distance h isΔg
<h3>What is vertical?</h3>
- The distance between two vertical places is known as the vertical separation or vertical distance. There are numerous ways to express vertical position using vertical coordinates, including depth, height, altitude, elevation, etc.
- The formula for vertical distance from the ground is y = - g * t2 / 2, where g is the acceleration of gravity and h is a height.
- The vertical distance between the measurement point and the point of observation on Earth's surface. Altitude is the vertical distance from the measurement place to mean sea level.
Assuming h is small in comparison to the radius of the Earth, show that the difference in free-fall acceleration between two points separated by vertical distance h isΔg = (2GMeH) / RE³:
Given:
Separated between two points=h
And, h∠∠
(= radius of the Earth)
Now, 
Δg
Therefore, Vertical distance h isΔg

The value is 
Explanation:
Generally the relative speed at which you are moving with respect to the person ahead of you is mathematically represented as
substituting 1.05 m/s for 
and 2.75 m/s for 
So
=> 
Generally the distance by which the person is ahead of you is mathematically represented as
substituting 18.5 s for 
=>
Answer:
Explanation:
First, we can find the mass of the object in air
Since W = mg
m = W/g = (8.9)/(9.8) = 0.908 kg
Then, by Archimedes principle, we can find its volume. The volume is found by the weight of the water displaced by the formula
W = Vρg
The Weight is the difference in scale readings. The density of water is 1000 kg/m3
(8.9- 7.8) = V(1000)(9.8)
Thus V = 1 X 10-4 m3
Then, since density is mass / volume
ρ = 0.908/1 X 10-4
ρ = 8254 kg/m3 which is 8 X 103 kg/m3
The density of gold is 19.3 X 103 kg/m3
Since those densities are not the same, the crown is either hollow or not pure gold
