Is yeast a livingthings? And explain the answer (how do you know?)

1 answer:

6 0

Yeast is a living organism, and it respires or breathes, through its cells. During the respiration process, glucose and oxygen are combined and turned into C0₂, also known as carbon dioxide. It's also converted into alcohol which releases energy from the cell(s). The term "respiration" that was used, derives from any chemical process which releases energy from food. As a side note, yeast is a unicellular organism, meaning that they only have one cell, but deriving from multicellular ancestors.

I hope I helped :)

Can the magnitude of a vector ever (a) be equal to one of its components, or (b) be less than one of its components? 9. Can a pa

Ber [7]

Answer:

a) the other components are zero, in the direction of one of the coordinate axes

b) the magnitude is less than the value of one of its components, it must occur when the vector is in some arbitrary direction

9) constant velocity the acceleration must necessarily be zero,

constant speed can be accelerated since it may be changing the direction of the velocity vector

Explanation:

Vectors are quantities that have modulo (scalar) direction and sense.

a) If in a vector its magnitude is equal to one d its components implies that the other components are zero, therefore the vector must be in the direction of one of the coordinate axes

b) if the magnitude is less than the value of one of its components, it must occur when the vector is in some arbitrary direction, other than the direction of the axes, that is

R² = x² + y²

where R is the magnitude of the vector e x, and are the components

9) When a particle has a constant velocity, the acceleration must necessarily be zero,

v = vo + a t

The bold letters indicate vectors If a = 0 implies that v = vo

If a particle has constant speed it can be accelerated since it may be changing the direction of the velocity vector, this type of acceleration has the name of centripetal acceleration

A weight of 50.0 N is suspended from a spring that has a force constant of 210 N/m. The system is undamped and is subjected to a

Fittoniya [83]

Answer:

The maximum value of the driving force is 1044.01 N.

Explanation:

Given that,

Weight of the object, W = 50 N

Force constant of the spring, k = 210 N/m

The system is undamped and is subjected to a harmonic driving force of frequency 11.5 Hz.

Amplitude, A = 4 cm

We need to find the maximum value of the driving force. The force is given by the product of mass and maximum acceleration as :

$F=mA\omega^2$ .....(1)

A is amplitude

m is mass,

$m=\dfrac{W}{g}\\\\m=\dfrac{50}{10}\\\\m=5\ kg$

$\omega$ is angular frequency

Angular frequency is given by :

$\omega=2\pi f\\\\\omega=2\pi \times 11.5\\\\\omega=72.25\ rad/s$

Equation (1) becomes :

$F=5\times 0.04\times 72.25^2\\\\F=1044.01\ N$

So, the maximum value of the driving force is 1044.01 N.

A tissue box has regular dimensions

vova2212 [387]

Considering the volume of a rectangle, the volume of the tissue box is 3,239.1 cm³.

<h3>What is volume</h3>

Volume is a scalar-type metric quantity that is defined as the extension in three dimensions of a region of space. In other words, the volume corresponds to the space that the shape occupies.

<h3>Volume of a rectangle</h3>

To calculate the volume of a rectangle, it is necessary to multiply its 3 dimensions: length ×width×height. Volume is expressed in cubic units.

<h3>Volume of the tissue box</h3>

In this case, you know:

Length: 11.8 cm
Width: 12.2 cm
Height: 22.5 cm

Replacing in the definition of volume of a rectangle:

Volume of the tissue box= length ×width×height

Volume of the tissue box= 11.8 cm× 12.2 cm× 22.5 cm

Solving:

<u><em>Volume of the tissue box= 3,239.1 cm³</em></u>

Finally, the volume of the tissue box is 3,239.1 cm³.
