Explanation:
formation of compounds because the electric forces compel the atoms to attract each other and formed bonds which leads to the formation of chemical compounds. The attractive or repulsive interaction between any two charged bodies is known as an electric force so the attraction between two opposite charged atoms causes the formation of compounds so we can conclude that electric forces are important for the formation of compounds.
Answer:
Explanation:
The definition of the intensity in terms of power is given by:
Where:
- P is the power
- A is the area
If the sound emits uniformly in all directions and that there are no reflections, we can assume the geometry of the wave sound is spherical.
Let's recall the area of a sphere is
To the first location we have:
and to the second location we have:
Now, we can divide each intensity to find the second intensity.
I hope it helps you!
Answer:
Explanation:
Let the initial speed of the ball is given as
then angle of inclination is given as 33 degree
now its two components of velocity is given as
now the two positions with time given as
now when it hit the wall so we will have
now from above two equations we will have
now from above equations again
Not 100% but i think it'll cause the earth to rotate slightly slower, its definitely not the last one though
