Assume you drink 250ml of soda out of a 1 liter soda bottle. how many liters are left?

charle [14.2K]

The correct answer is 0.75 liters.

<h3>Briefing:</h3>

One liter of soda produced 250 ml of beverage.

1 liter is equal to 1000 milliliters.

250 ml was consumed, or 250/1000 or 0.25 liter.

There was 1 - 0.25 liters of soda left

0.75 liter of soda was left and the correct answer is 0.75 liter.

<h3>What is a liter of water?</h3>

Four glasses of water make up one liter, to be precise.

Let us understand this using the following explanation. Despite the fact that there is no set standard size for glasses, their capacity varies. In contrast, we calculate that a liter holds 32 ounces and a glass holds 8 ounces of water.

<h3>How are liters measured?</h3>

Convert the object's dimensions into centimeters before performing the volume calculation in litres. Next, determine a shape's volume using the volume formula. For instance, you could use Volume = length times width times height to determine the volume of a cube, and the result would be in cubic centimetres.

When mass m is tied to the bottom of a long, thin wire suspended from the ceiling, the wire's second-harmonic frequency is 180 h

Katena32 [7]

The frequency of the nth-harmonic of a string is given by
$f_n = \frac{n}{2L} \sqrt{ \frac{T}{\mu} }$
where n is the number of the harmonic, L is the length of the string, T the tension and $\mu$ the linear density.

In our problem, since the mass m is tied to the string, the tension is equal to the weight of the object tied:
$T=mg$
Substituting into the first formula, we have
$f_n = \frac{n}{2L} \sqrt{ \frac{mg}{\mu} }$

In our problem we have n=2 (second harmonic). In the previous equation, the only factor which is not constant between the first and the second part of the problem is m, the mass. So, we can rewrite everything as
$f_2 = K \sqrt{m}$
where we called
$K= \frac{2}{2L} \sqrt{ \frac{g}{\mu} }$

In the first part of the problem, the mass of the object is m and $f_2 = 180 Hz$ . So we can write
$180 Hz = K \sqrt{m}$

When the mass is increased with an additional 1.2 kg, the relationship becomes
$270 Hz = K \sqrt{(m+1.2 Kg)}$

By writing K in terms of m in the first equation, and subsituting into the second one, we get
$180 Hz \sqrt{ \frac{m+1.2 Kg}{m} }=270 Hz$
and solving this, we find
$m=0.96 kg$
