Answer:
20 seconds
Explanation:
we know,
speed=distance by time
therefore time= distance by speed
so,
time=5000m by 25m|s
=20 seconds
Answer: The number of people that work in the white house are 200. If that is your question? If not just let me know and i will gladly help.
Answer:
Direction
Explanation:
A vector is a geometrical representation of physical quantity. It has a particular direction with a specific magnitude.
In the geometry of space whether it is two dimensional or three dimensional the vector quantity has a specific direction. Such as a stone is thrown with a velocity in a particular direction.
The path of the stone in three-dimension shows its direction and speed is its magnitude.
Hence, the velocity of stone has two property magnitude mentioned as speed and particular direction.
On writing the mathematical expressions for vectors, it is denoted by arrow mark on its top as shown below.

Line graphs tend to show a change in data over time.
To solve this problem we will apply the principles of energy conservation. The kinetic energy in the object must be maintained and transformed into the potential electrostatic energy. Therefore mathematically


Here,
m = mass (At this case of the proton)
v = Velocity
k = Coulomb's constant
= Charge of each object
r= Distance between them
Rearranging to find the second charge we have that

Replacing,


Therefore the charge on the sphere is 3.6531nC
