What are 5 fun facts about cytoplasm?

1 answer:

5 0

You could google it... but here are some facts anyway:
1. cytoplasm is about 80% water but also contains dissolved carbs, proteins and fats.
2. the nucleus has its own type of cytoplasm that is slightly different than that of the rest of the cell. it is called nucleoplasm.
3. when cytoplasm is in a watery state, it is called cytosol and when it's more jelly-like, it is called cytogel
4. in an animal cell, cytoplasm gives the cell its shape.
5. cytoplasm is a good conductor of electricity.

A sound wave travels in a straight line at a constant speed of 660 mph. What is

Fed [463]

Answer:

a = 0

Explanation:

The velocity of a sound wave in a straight line is 660 mph. The wave is moving with a constant velocity. It means that the change in velocity is equal to 0.

We know that acceleration of an object is equal to the change in velocity divided by time taken. But here the change in velocity is 0. As a result the acceleration of the sound wave is 0.

Which wave characteristics is defined as the number of cycles of a periodic wave occurring per unit time?

Assoli18 [71]

<h3><u>Answer;</u></h3>

Frequency

<h3><u>Explanation;</u></h3>

<em><u>Waves are disturbances that travel through a material medium. There are several characteristics of waves, which includes; wavelength, frequency, period and amplitude. </u></em>
Amplitude is the maximum displacement of wave particles, or simply the height of the wave, measured in meters.
Wavelength is the distance between adjacent crests or troughs in a transverse wave or between two successive rarefaction or compressions in a longitudinal wave, measured in meters.
Period is the time it takes for one complete wave to pass a given point, measured in seconds.
<em><u>Frequency is the number of complete waves or cycles that pass a point in one second, measured is inverse seconds, or Hertz (Hz).</u></em>

Force → F = ( − 8.0 N ) ˆ i + ( 6.0 N ) ˆ j acts on a particle with position vector → r = ( 3.0 m ) ˆ i + ( 4.0 m ) ˆ j . What a

andrey2020 [161]

Explanation:

It is given that,

Force, $F=(-8\ N)i+(6\ N)j$

Position vector, $r=(3i+4j)\ m$

(a) The torque on the particle about the origin is given by :

$\tau=F\times r\\\\\tau=(-8i+6j)\times (3i+4j)\\\\\tau=(-50k)\ N-m$

(b) To find the angle between r and F use dot product formula as :

$F{\cdot} r=|F||r|\ \cos\theta\\\\\cos\theta=\dfrac{F{\cdot} r}{|F| |r|}\\\\\cos\theta=\dfrac{(-8i+6j){\cdot} (3i+4j)}{\sqrt{(-8)^2+6^2} \times \sqrt{3^2+4^2} }\\\\\cos\theta=\dfrac{-24+24}{\sqrt{(-8)^2+6^2} \times \sqrt{3^2+4^2} }\\\\\cos\theta=0\\\\\theta=90^{\circ}$

Hence, this is the required solution.
