When you stroke the prongs with a wire, a static sound is being produced. <span>This kind of minimum-information </span>noise<span> is </span>called white noise, by analogy with white<span> light which is a uniform mixture of all the different possible colors. Hope this helps.</span>
Answer:
bring each tube close to the plastic ball and note any movement of the ball
Explanation:
study island
just took the test!!!!!
That statement is <em>false</em>.
"Condense" is what a gas does when it turns into liquid, and that's something that happens when the gas is cooled, not heated.
Explanation:
In physics, work is the energy transferred to or from an object via the application of force along a displacement. In its simplest form, it is often represented as the product of force and displacement. A force is said to do positive work if (when applied) it has a component in the direction of the displacement of the point of application. A force does negative work if it has a component opposite to the direction of the displacement at the point of application of the force.

Work
A baseball pitcher does positive work on the ball by applying a force to it over the distance it moves while in his grip.

For example, when a ball is held above the ground and then dropped, the work done by the gravitational force on the ball as it falls is equal to the weight of the ball (a force) multiplied by the distance to the ground (a displacement). When the force F is constant and the angle between the force and the displacement s is θ, then the work done is given by:
{\displaystyle W=Fs\cos {\theta }}{\displaystyle W=Fs\cos {\theta }}
Work is a scalar quantity, so it has only magnitude and no direction. Work transfers energy from one place to another, or one form to another. The SI unit of work is the joule (J), the same unit as for energy.
