Answer:

Its form is affected

Explanation:

A physical change implies only a modification in the physical properties of a substance. Contrary to this in a chemical change not only its form but its composition changes.

Processes like melting, transition to a gas, change of strength, textural change, shape, size, color, volume, and density, are examples of physical changes.

How can a bulb be resistor?​
valkas [14]

Answer: The reason a light bulb glows is that electricity is forced through tungsten, which is a resistor. The energy is released as light and heat. A conductor is the opposite of a resistor. Electricity travels easily and efficiently through a conductor, with almost no other energy released as it passes.

"a musical tone sounded on a piano has a frequency of 261.6 hz and a wavelength of 1.31 m. what is the speed of the sound wave
Andreyy89
To solve this question, we use the wave equation which is:
C=f*λ
where:
C is the speed;
f is the frequency;
λ is the wavelength
So in this case, plugging in our values in the problem. This will give us:
C = 261.6Hz × 1.31m
= 342.696 m/s is the answer.
