Answer:

Ribosomes: Produce proteins by following coded instructions that come from DNA.

Endoplasmic reticulum: Where lipids, including those needed for the cell membrane, are synthesized, along with proteins and other materials that are exported from the cell.

Vesicles: Store and move materials between cell organelles, as well as to and from the cell surface.

Golgi apparatus: Modifies, sorts, and packages proteins and other materials from the endoplasmic reticulum for storage in the cell or release from the cell.

A reaction taking place in a container with a piston-cylinder assembly absorbs 4850. J of heat and has a change in the internal

Maslowich

Answer:

$V_f = 16.3 Ltr$

Explanation:

As per first law of thermodynamics we know that

heat absorbed = change in internal energy + Work done

so we have

$Heat = 4850 J$

$\Delta U = 1618.5 J$

so work done is given as

$4850 = 1618.5 + W$

$W = 3231.5 J$

now we know that at constant pressure the work done is given as

$W = P\Delta V$

$3231.5 = P(V_f - V_i)$

$3231.5 = 5.5 \times 1.01 \times 10^5(V_f - 10.5 \times 10^{-3})$

$V_f = 16.3 \times 10^{-3} m^3$

or we have

$V_f = 16.3 Ltr$

Answer:

The right solution is "126 Psi".

Explanation:

The given values are:

P₁ = 130 psig

i.e.,

= $130\times 6.894$

= $896.22 \ Kpa$

or,

= $896.22\times 10^3 \ Pa$

Z₂ = 10ft

= 3.05 m

$\delta$ = 1000 kg/m³

According to the question,

Z₁ = 0

V₁ = V₂

As we know,

⇒ $\frac{P_1}{\delta_g} +\frac{V_1^2}{2g} +Z_1=\frac{P_2}{\delta_g} +\frac{V_2^2}{2g} +Z_2$

On substituting the values, we get

⇒ $\frac{P_1}{\delta_g} +0+0=\frac{P_2}{\delta_g} +0+Z_2$

⇒ $\frac{896.22\times 10^3}{1000\times 9.8} =\frac{P_2}{1000\times 9.8} +3.05$

⇒ $P_2=866330 \ P_a$

i.e.,

⇒ $=866330\times 0.000145$

⇒ $=126 \ Psi$

Well you never specified what you're asking... however, this might help you learn the concepts of displacements and magnitude.

: The official displacement formula is as follows: s = sf - si. s = displacement; si = initial position; sf = final position

magnitude is the quantitative value of seismic energy. It is a specific value having no relation with distance and direction of the epicentre.

the magnitude of a vector in any dimension. For a 2d vector the formula is [math]|z| = \sqrt{x^2+y^2}[/math], where x and y are the x and y components of the vector respectively.
