Phase is an expression related to vibration. Just like phase 1 phase 2, phase 3 etc, it's basically a stage a particle is in, in its travel. Same phase means all the particles are in same stage of traveling, therfore same speed and direction.
Answer:
Magnitude = 26 m
Direction = eastward
Explanation:
Given that a football coach walks 24 meters eastward, then 12 meters westward, then 36 meters eastward, and finally 22 meters westward. What is the magnitude and direction of the displacement?
Let eastward be positive and westward be negative.
Magnitude = 24 - 12 + 36 - 22
Magnitude = 60 - 34
Magnitude = 26
Since the answer is positive, the direction will be eastward.
Therefore,
Magnitude = 26 m
Direction = eastward
Answer:
2950 m
Explanation:
The radius to which the sun must be compressed to become a black hole is equal to its Schwarzschild radius, which is given by the formula:
where
G is the gravitational constant
M is the mass of the star
c is the speed of light
For the Sun, its mass is
Therefore, its Schwarzschild radius is
Answer:
Explanation:
According to Coulomb's law, the magnitude of the electric force between two equals charges (q) is given by:
Here k is the coulomb constant and d is the distance between the charges. For two electrons we have:
Thanks for points...
But can you type this question.. As it becomes hard to answer if it's in the picture..
