Answer:
I'm not taking physics right now but I would love too.
Explanation:
Look up what there both made out of and it will tell you but basically it’s b/c of what there made out of and the chemicals in the tea (drink)
First:
5 cm = 0,05 m
Now, the formula:
F = k * (qq') / r²
Replacing:
F = 9x10⁹ * (55x10⁸ * 1x10⁷) / 0,05²
F = 9x10⁹ * (5,5x10¹⁶ / 2,5x10⁻³)
F = 9x10⁹ * 2,2x10¹⁹
F = 1,98x10²⁹
The force between the charges is 1,98x10²⁹ Newtons.
Answer:
A. an increase in the height of the sound wave
Explanation:
Volume of the sound is measured by its intensity
So here we know that
intensity is directly depends on the square of the amplitude of the sound wave
so here as intensity depends on the loudness of the sound given as
so here as the loudness of sound will increase then the intensity will increase and hence the amplitude of the sound will also increase
So correct answer will be
A. an increase in the height of the sound wave
Answer:
a) horizontal range s=277671.77 m
b) time the shell is in motion 301.143 s
Explanation:
Is a parabolic movement so the velocity have two components:
