Answer:
The distance of separation is decreased
Explanation:
From Cuolomb's law, we know that the strength of charge is inversely proportional to the distance of separation between the charges. To mean that increasing the distance let's say from 2m to 3 m would mean initial strength getting form 1/4 to 1/9 which is a decrease. The vice versa is true hence the force of repulsion can increase only when we decrease the distance of separation.
Answer:
The correct answer is
a) 1, 2, 3
Explanation:
In rolling down an inclined plane, the potential energy is Transferred to both linear and rotational kinetic energy thus
PE = KE or mgh = 1/2×m×v² + 1/2×I×ω²
The transformation equation fom potential to kinetic energy is =
m×g×h = ![\frac{1}{2} mv^{2} + \frac{1}{2} (\frac{2}{5} mr^{2} )(\frac{v}{r}) ^{2}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%20mv%5E%7B2%7D%20%2B%20%5Cfrac%7B1%7D%7B2%7D%20%28%5Cfrac%7B2%7D%7B5%7D%20mr%5E%7B2%7D%20%29%28%5Cfrac%7Bv%7D%7Br%7D%29%20%5E%7B2%7D)
= ![\sqrt{\frac{10}{7} gh}](https://tex.z-dn.net/?f=%5Csqrt%7B%5Cfrac%7B10%7D%7B7%7D%20gh%7D)
= ![\sqrt{gh}](https://tex.z-dn.net/?f=%5Csqrt%7Bgh%7D)
=![\sqrt{\frac{4}{3} gh}](https://tex.z-dn.net/?f=%5Csqrt%7B%5Cfrac%7B4%7D%7B3%7D%20gh%7D)
Therefore the order is with increasing rotational kinetic energy hence
the first is the sphere 1 followed by the disc 2 then the hoop 3
the correct order is a, 1, 2, 3
The constant is the temperature of the air that the plants get.
The independent variable is the thing that YOU control. That's the amount of sunlight each plant gets.
The <em>dependent variable</em> is anything that's caused by changes in the independent variable. That's the growth of the plants.
Answer:
The ladder is 3.014 m tall.
Explanation:
To solve this problem, we must use the following formula:
v = x/t
where v represents the woman’s velocity, x represents the distance she climbed (the height of the ladder), and t represents the time it took her to move this distance
If we plug in the values we are given for the problem, we get:
v = x/t
2.20 = x/1.37
To solve this equation for x (the height of the ladder), we must multiply both sides by 1.37. If we do this, we get:
x = (2.20 * 1.37)
x = 3.014 m
Therefore, the ladder is 3.014 m tall.
Hope this helps!
Answer:
cytoplasm and channel gates
Explanation:
The movement originates from the cytoplasm. This is the fluid medium through which ions are shuttle from one place to another. However, though simple as it might appear to be, the movement requires carrier proteins. The are proteins that facilitate in the movement of the ions. These proteins have specially controlled gates called channel proteins. These are regulated proteins that open and close based on hydrogen ion concentration. These proteins are able to facilitate the movement of ATP molecules.
