Answer:

Unit Cell

Explanation:

A unit cell is the smallest fundamental particle of a crystal structure that represents the structure of a crystal.

Long-range, three-dimensional repetitiveness of this unit cell forms a crystal. A unit cell is composed of ions or atoms in a particular arrangement forming a well-defined structure.

Crystal have a sharp melting and boiling point and when cut using a tool, they give a sharp edge on the pieces.

Answer:

1. Frequency = speed / wavelength

here we know

speed = 343 m/s

wavelength = 0.77955 m

now frequency is given by

$f = \frac{343m/s}{ 0.77955m}$

f = 440 Hz

2. Frequency = speed / wavelength

here we know

speed = 343 m/s

wavelength = 0.52028 m

now frequency is given by

$f = \frac{343m/s}{ 0.52028m}$

f = 659.3 Hz

3. Frequency = speed / wavelength

here we know

speed = 343 m/s

wavelength = 0.65552 m

now frequency is given by

$f = \frac{343m/s}{ 0.65552m}$

f = 523.25 Hz

4. Wavelength = speed / Frequency

here we know

speed = 343 m/s

Frequency = 587.33 Hz

now wavelength is given by

$\lambda = \frac{343m/s}{587.33}$

$\lambda = 0.584 m$

5. Wavelength = speed / Frequency

here we know

speed = 343 m/s

Frequency = 493.88 Hz

now wavelength is given by

$\lambda = \frac{343m/s}{493.88}$

$\lambda = 0.6945 m$

6. Wavelength = speed / Frequency

here we know

speed = 343 m/s

Frequency = 698.46 Hz

now wavelength is given by

$\lambda = \frac{343m/s}{698.46}$

$\lambda = 0.491 m$

7. Frequency = speed / wavelength

here we know

speed = 343 m/s

wavelength = 0.5840 m

now frequency is given by

$f = \frac{343m/s}{0.5840m}$

f = 587.3 Hz

8. Frequency = speed / wavelength

here we know

speed = 343 m/s

wavelength = 0.4375 m

now frequency is given by

$f = \frac{343m/s}{0.4375m}$

f = 784 Hz

9. Wavelength = speed / Frequency

here we know

speed = 343 m/s

Frequency = 783.99 Hz

now wavelength is given by

$\lambda = \frac{343m/s}{783.99}$

$\lambda = 0.4375 m$

10. Wavelength = speed / Frequency

here we know

speed = 343 m/s

Frequency = 659.26 Hz

now wavelength is given by

$\lambda = \frac{343m/s}{659.26}$

$\lambda = 0.520 m$

Considered the statement "You can move parts of your body because of energy from the sun. "Described a series of energy conversi

Masja [62]

Answer:

Explanation:

The source of all forms of energy found on the earth except nuclear energy is the sun . So energy used by us to do daily activities also comes from the sun .

The plants trap the solar energy in the form of light to make food material for us like sugar , carbohydrates etc . This energy is stored here in the chemical bonds formed in them.

We take this food in the form of carbohydrate, fat etc. We digest it to mix this food carbohydrate in blood . It is further broken down on being absorbed by the cell in our body . They break them to produce a compound like ATP ( adenocine triphosphate ) which is energy rich compound . It is converted into ADP and difference of energy is released . This energy is used by us in moving body parts.

A 13kg box slides 4.0m down the frictionless ramp shown in the figure , then collides with a spring whose spring constant is 170

Svetradugi [14.3K]

The force on the box is:
F = mgsin∅
If we multiply by this with the distance it traveled, we will know the work done by the box.
W = dmgsin∅

This work will be converted to elastic potential energy in the spring which is:
1/2 kx². Equating these and substituting values:
1/2 * 170 * x² = 4 * 13 * 9.81 * sin(30)
x = 1.73 m

The box's maximum speed will at the point right before contact with the spring, when the compression is 0.
