Answer:
0J
Explanation:
The gravitational potential energy of the body is 0J because the height is at 0m.
Gravitational potential energy is a form of energy which is highly dependent on the position of a body. The relative position of a body in space accounts for the amount of gravitational potential energy they posses.
- A body at height 0m has no gravitational potential energy:
Gravitational potential energy = mgh
m is the mass of the body
g is the acceleration due to gravity
h is the height
So, if h = 0, Gravitational potential energy will become 0.
Answer:
A good conductor is copper because it conducts the energy flow of electrons easily.
Explanation:
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

Given:
Object in circular motion 25 m/s
1 second to go quarter circle
Required:
Centripetal acceleration:
Solution:
Acceleration = v2/r
Where v is the velocity and r is
the radian
Substituting the values into the
equation,
Acceleration = v2/r = (25
m/s)2/(4*pi/180) = 8952.47 m2/s2
Answer:
The reason for phonograph installation is to provide information about humans to interstellar aliens.
Explanation:
Phonographs are archaic forms of gramophone which are able to record and reproduce sound.Phonographs were used in early days in voyagers to help transmit information about humans to nearby alien species in space.
