Answer:
Explanation:
In order to find the force between the two electrons, we need to use Coulomb's law. In its scalar form, the law is given by:
Where:
The electric charge of an electron is a known constant given by:
So:
Therefore, replacing the data provided in the Coulomb's law equation:
Answer:
13 blocks
Explanation:
The total distance the student travels is 13 blocks.
Distance is the length of path covered during the motion of a body.
To find distance:
Total distance = Number of blocks to the west + number of blocks to the north + number of blocks to the east
Total distance = 3blocks + 4blocks + 6blocks = 13blocks
Answer:e
Explanation:
As the Pendulum swings back and forth its kinetic energy is converted into potential and Potential into kinetic .
At highest point Pendulum is momentarily at rest and thus possess all the energy in the form of Potential Energy which is converted into kinetic energy as the pendulum moves downward.
The kinetic energy is maximum at mean position i.e. at lowest point.
Thus all of the given options are true
Answer:
A. Expanding personal knowledge by reading articles from scientific
journals
B. Analyzing the different parts of a physical phenomenon to see
how they fit together
C. Predicting the impact that answering an important scientific
question would have on people
D. Developing a question that can be answered through testing or
observation
E. Developing logical arguments for providing incentives for
scientific research
Answer:
a) 1/4 what it is now
Explanation:
As we know that force of gravitation between two planets at some distance "r" from each other is given as
now since we know that if the distance between Earth and Sun is changed
So the force of gravity will be given as
now we know that the distance between sun and earth is changed to twice the initial distance between them
so we have
so new gravitational force between sun and earth is given as
