Paragraph about cell wall

Physics

algol [13]3 years ago
7 0
Animal cells do not have cell walls, nor do protozoa. Cell walls protect the cells from damage. It is also there to make the cell strong, to keep its shape, and to control the growing of the cell and plant. The cell wall is the tough, usually flexible but sometimes fairly rigid layer that surrounds some types of cells

All you need to know about the cell wall is that it protects the cells inside of it.

Distance measurements based on the speed of light; used for objects in space
Vika [28.1K]

Answer : Yes, distance measurements based on the speed of light used for objects in space.

Explanation :  A light year is measurement  of distance  that light travel in a one year.

In a one year light travels 9460000000000 kilometer.

We know that, speed of light is 3\times10^{8}\ m/s

and  time is 31536000 seconds in 1 year

so, distance = speed of light X time

Now, the light year is 9.4608\times10^{15} meter

Example : The nearest star to earth is about 4.3 light year away.

Yuri [45]
Longitudinal waves have energy that vibrates parallel to the medium - a compression is the region of greatest density and the rarefaction the region of highest density .The rarefaction (much like the maximum amplitude in a transverse wave) has a region of lowest density, typically situated in the exact center of the region.

A meter stick balances horizontally on a knife-edge at the 51 cm mark. With two nickels stacked over the 6.0 cm mark, the stick
Oliga [24]

Answer:

65g

Explanation:

Two main conditions for equilibrium are:

I. The resultant force must be equal to zero. That is, sum of the forces acting in one direction about a point must be equal to the sum of the forces acting in the opposite direction about the same point.

II. The resultant moment must be equal to zero. That is, sum of the moments in one direction about a point must be equal to the sum of the moments in another direction about the same point.

For the above question,

the 51cm mark is the point where the resultant weight of the meter stick lies,

the pivot or point is the 45cm mark where the stick balanced when 2 nickels ( total mass (5.0g x 2) 10g were placed at the 6cm mark.

Using the conversion factor:

1000g(1kg) = 10N, we can convert mass to weight, calculate the weight of the meter stick then reconvert to mass.

That is,

mass of 2 nickels = 10g = 10/1000 = 0.01N.

Moment = Force x distance from line of force to pivot of rotation

Applying the principle of equilibrium,

Moment of left side = Moment of right side

0.01 x (45-6) = W x (51-45)

Where W = weight of the meter stick

W x 6 = 0.01 x 39

W x 6 = 0.39

W = 0.39/6

W= 0.065N

Therefore, mass of meter stick = 0.065 x 1000 = 65g.
