Answer:
FALSE
Explanation:
The answer is false.
The speed of the sound in water is faster when compared to the speed of sound in air. This is because, the particles in air is loosely packed and are far from each other as compared to water or liquid.
The water particles are close to each other than air particles, so water particles are able to transmit the vibrations of the sound faster than the air particles.
Therefore sound waves travels faster in water than in air.
Answer:
Alignment of charges at the surface of an object producing an induced charge is known as POLARIZATION
Explanation:
Polarization is a characteristic of certain electromagnetic radiations in which the direction and magnitude of the vibrating electric field are related in a specific way.
There are four types of Polarization which include
Electronic Polarization
Ionic Polarization
Orientation Polarization
Space Charge Polarization
B. by taking measurements during an experiment
<span>To find the kind of transformation that describes this change from d(v) = 0.045v2 to d(v) = 0.039v2, find the relation between the two functions:
0.045/.039 = 45/39 = 15/13
The you have to multiply the first function times 13/15 to transform it to the second function.
When you multiply by a factor less than one you are compressiong the function vertically (if you multiply by a factor greater than 1 you are stretching vertically).
On the other hand, that the distance to stop the minimum braking distance will be smaller with the second function.
Then, the answer is that the transformation is a vertical compression by a factor of 13/15 and the braking distance will be less with optimum new tires than with tires having more wear.
