<h2>Answer: remain stationary</h2>
Stationary waves (so called because they seem to be immobile) occur when two waves interfere with the <u>same frequency, amplitude but with different direction</u>, along a line with a phase difference of half wavelength.
In this kind of waves there are two types of points:
The nodes, which are points that remain motionless or stationary and do not vibrate. They are due to the destructive interference of both waves when they meet.
The antinodes, which are points that vibrate with a maximum vibration amplitude. They are due to the non-destructive interference of both waves.
According to this explanation and comparing it with the description, when this two waves pass through each other, the point P will become a node, hence<u> it will remain stationary</u>.
Answer:
D
Explanation:
If the distance is reduced by factor of 2, lets say the distance was 10cm
reducing by a factor of 2 will leave the distance at 5cm
so the electric force increases by a factor of 2
Answer:
i dont exactly know the answer but i do know the formula
Explanation:
1/ 1/R1 + 1/ R2+
An atom's negative particles are surrounded by positive matter, so the positive particles are easier to remove. Thomson's atom model is formed by positive and negative particles The positive particles are bigger than the negative,but the atom is still in equilibrium,this is possible because they have the same“density if you wanna call it like that。So,the properties of negative particles allow them to move free。On the other hand,bigger particles,don't have free moving like negative particles。That's why electrons(negative particles)are the definition of electricity,because they can move easily,although this movement depend on the material,metal are better to move in than wood or plastic.
