Answer:
<h2>69.3 g</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
mass = Density × volume
From the question we have
volume = 55 mL
density = 1.26 g/mL
mass = 1.26 × 55 = 69.3 g
We have the final answer as
<h3>69.3 g</h3>

I believe your answer would be friction...
Water
It can be a solid or a liquid
From the relationship between wavelength and frequency, the frequency of the wave is reduced by half to 60 Hz as the wavelength is increased twice to 10 m at constant speed.
<h3>What is the relationship between wavelength, velocity and frequency of a wave?</h3>
The velocity, frequency and wavelength of a wave are related by the formula given below:
where
- v is velocity
- f is frequency
- λ is wavelength of the wave
From the above relationship:
If the wavelength of a wave is increased to 10m but the speed stays the same at 600 m/s, the frequency can be calculated as follows:
f = v/λ
f = 600/10
f = 60 Hz
Therefore, the frequency of the wave is reduced by half as the wavelength is increased twice at constant speed.

The most likely evidence of an energy transformation taking place when a <em>wire</em> is twisted and turned breaks is that the broken ends of the wire turn warm (even very hot if it was twisted and turned vigoroulsy).
The heat (thermal energy) evolves due to the internal friction developed by the relative motion of the internal particles of the wire, being kinetic energy transformed into heat energy.
It is the same phenomenon that is observed when a saw cuts a piece of metal and the reason why a cooling fluid is poured over the pieces of metal to avoid that the temperature raises too much.
