Why does carpet tend to produce differences in static electricity more that hardwood or tile floors

Physics

Answer:

This is because the rubbing releases negative charges, called electrons, which can build up on one object to produce a static charge. For example, when you shuffle your feet across a carpet, electrons can transfer onto you, building up a static charge on your skin.

Explanation:

This is because the rubbing releases negative charges

Given your choice for part 1, would it be possible, in principle under ideal circumstances, for a balloon to stick to a wall ind

podryga [215]

Answer:

Explanation:1)Rub a balloon on your head and stick it to the wall. And it sticks—very nice. We’ve

talked in lecture about why it sticks. This question is about why, after a while, it fall off.

Consider each of the following explanations.

i) It falls because it uses up the energy you put on it when you rubbed it.

ii) It falls because it uses up the charge you put on it when you rubbed it.

iii) It falls because the energy you put on it slowly leaks off into the wall or the air.

iv) It falls because the charge you put on it slowly leaks off into the wall or the air.

Answer: It falls because the charge you put on it slowly leaks off into the wall or the air.

2) Given your choice for part a, would it be possible, in principle under ideal

circumstances, for a balloon to stick to a wall indefinitely?

Answer: If you can keep the charge from leaving the balloon, And if the

wall is a very good insulator also this will prevent the ball from falling.

Acceleration occurs whenever an ___________________ force acts on an object.

leonid [27]

Acceleration occurs whenever the forces on an object are unbalanced.

It's the group of forces on the object that's either balanced or unbalanced.
There's no such thing as "an unbalanced force".

The loudness of a sound is determined by the __________, or height, of the sound wave.

NISA [10]

Answer: Aplitude

Explanation: Loudness depends on the amplitude,or height, of sound waves. The greater the amplitude, the louder the sound perceived. Amplitude is measured in decibels.

If you walk a distance of 8 blocks and then 3 blocks south from home, what is your position compared to home? What distance did

Harman [31]

The position compared to that of home is a reference to displacement, I believe.

Displacement = x total - x initial

So I believe the answer is 5 blocks due north (if you’re walking linearly from your home), unless the questions is referring to relative displacement, in which then you’d need to use the Pythagorean theorem to find the hypotenuse between both positions. And then you’d have to find theta for the degrees between the south direction and the other unmentioned direction. But I don’t think that’s the case.

Distance refers to x total and doesn’t care for direction, as this refers to a scalar quantity opposed to a vector. Thus the equation is just

d = x

So 8 blocks + 3 blocks = a distance of eleven blocks walked total

How does torque of rotating body relate to velocity

Fudgin [204]

Answer:

We know that the torque can be calculated as follows:

T = rpsinα

With r being the distance of the body from the center of the circumference he has as trajectory, p being the momentum of the body and sinα being the sine of the angle between the 2 vectors: r and p.

It's pretty obvious that T is directly proportional to the momentum, that can be written as p = m·v, with m being the mass of the object and v the velocity of the object.
