Answer:

             Height  = 1.9493 cm

             Width =  1.9493 cm

             Depth  =  1.9493 cm

Solution:

Data Given:

                  Mass  =  20 g

                  Density  =  2.7 g/mL

Step 1: Calculate the Volume,

As,

                                        Density  =  Mass ÷ Volume

Or,

                                        Volume  =  Mass ÷ Density

Putting values,

                                        Volume  =  20 g ÷ 2.7 g/mL

                                        Volume  =  7.407 mL or 7.407 cm³

Step 2: Calculate Dimensions of the Cube:

As we know,

                                        Volume  =  length × width × depth

So, we will take the cube root of 7.407 cm³ which is 1.9493 cm.

Hence,

                                        Volume  =  1.9493 cm × 1.9493 cm × 1.9493 cm

                                        Volume  =  7.407 cm³

A wave is moving towards shore with a velocity of 5.0 MS if it’s frequency is 2.5 Herz what is the wave length
EastWind [94]

Answer:

<h2>2 m</h2>

Explanation:

The wavelength of a wave can be found by using the formula

\lambda =  \frac{c}{f}  \\

where

c is the speed of the wave

f is the frequency

From the question

c = 5 m/s

f = 2.5 Hz

We have

\lambda =  \frac{5}{2.5}  = 2 \\

We have the final answer as

<h3>2 m </h3>

Hope this helps you

NaOH (aq) + HCl(aq) => NaCl(aq)+ H2O(l)

Na+(aq)+ OH - (aq) + H +(aq) +Cl - (aq) + Cl- (aq)
=> Na+(aq) + Cl - (aq) + H2O(l)
H+(aq) + OH-(aq) => H2O(l)

Eva pumps up her bicycle tire until it has a gauge pressure of 413 kilopascals. If the surrounding air is at standard pressure,
KIM [24]

The tire pressure is the sum of gauge pressure and the standard pressure of atmospheric pressure

We know that the standard air pressure of surrounding = 101.325 kPa

The given gauge pressure = 413 kPascal

So the tire pressure =  101.325 kPa + 413 = 514.325 K Pa

We can also convert the given pascals to atmosphere or Torr or mmHg or bar

What is the (a) frequency and (b) wavelength (in nm) of a source of purple light at the edge of the visible light spectrum?
stiv31 [10]

Answer: a) Frequency=666\times10^{12}Hz-789\times10^{12}Hz

b) Wavelength=380nm-450nm

Explanation: Visible light is a form of electromagnetic wave.

Wavelength is defined as the distance between two successive crests of a wave. It is represented as symbol \lambda.

Frequency is defined as the number of complete cycles happening per second. It is represented by the symbol \nu.

Wavelength and Frequency follow inverse relation,

                                              \nu=\frac{c}{\lambda}

where, c = speed of light = 3\times10^8m/s

Wavelength and frequency of a wave is usually expressed in a range.

a)  \text{Frequency of visible light}=666\times10^{12}Hz-789\times10^{12}Hz

b) \text{Wavelength of visible light}=380nm-450nm
