Where would old cell organelles be broken down to be recycled in the cell?

Lysosomes 'digest' them by secreting the lysozyme enzymes. I think that lysosomes ingest them, form vesicles containing the organelles, and then digest them with the aid of the enzyme. I hope this was helpful.

Korvikt [17]

By 272.7 degrees angle has planet Y rotated through during this time.

<h3 /><h3>What is Kepler's 3rd law?</h3>

The cubes of the semi-major axes of the planets' orbits are precisely proportional to the squares of the planets' orbital periods. According to Kepler's Third Law, as an orbiting planet's radius rises, so does the time of its orbit around the Sun.

Using Kepler's 3rd law, which says that the period of any planet's orbit squared is proportional to the radius of the orbit cubes, we can establish that

(period X / period Y)^2 = (radius X / radius Y)^3

(period X / period Y)^2 = 2^3 = 8

take sq root

period X / period Y = √8 = 2.82≅ 3

this means it takes planet X 2.82≅ 3 times longer to go through one orbit... so planet Y travels 2.82≅ 3 times as far (in its orbit...) as planet X!

This means...

planet Y travels 3 * 90.9 = 272.7 degrees

An electron and a proton each have a thermal kinetic energy of 3kBT/2. Calculate the de Broglie wavelength of each particle at a

IgorLugansk [536]

Answer:

The de Broglie wavelength of electron βe = 2.443422 × 10⁻⁹ m

The de Broglie wavelength of proton βp = 5.70 × 10⁻¹¹ m

Explanation:

Thermal kinetic energy of electron or proton = KE

∴ KE = 3kbT/2

given that; kb = 1.38 x 10⁻²³ J/K , T = 1950 K

so we substitute

KE = ( 3 × 1.38 x 10⁻²³ × 1950 ) / 2

kE = 4.0365 × 10⁻²⁰ ( is the kinetic energy for both electron and proton at temperature T )

Now we know that

mass of electron M'e = 9.109 × 10⁻³¹

mass of proton M'p = 1.6726 × 10⁻²⁷

We also know that

KE = p₂ / 2m

from the equation, p = √ (2mKE)

{ p is momentum, m is mass }

de Broglie wavelength = β

so β = h / p = h / √ (2mKE)

h = Planck's constant = 6.626 × 10⁻³⁴

∴ βe = h / √ (2m'e × KE)

βe = 6.626 × 10⁻³⁴ / √ (2 × 9.109 × 10⁻³¹ × 4.0365 × 10⁻²⁰ )

βe = 6.626 × 10⁻³⁴ / √ 7.3536957 × 10⁻⁵⁰

βe = 6.626 × 10⁻³⁴ / 2.71176984642871 × 10⁻²⁵

βe = 2.443422 × 10⁻⁹ m

βp = h / √ (2m'p ×KE)

βp = 6.626 × 10⁻³⁴ / √ (2 × 1.6726 × 10⁻²⁷ × 4.0365 × 10⁻²⁰ )

βp = 6.626 × 10⁻³⁴ / √ 1.35028998 × 10⁻⁴⁶

βp = 6.626 × 10⁻³⁴ / 1.16201978468527 × 10⁻²³

βp = 5.702140 × 10⁻¹¹ m

Two particles are traveling through space. At time t the first particle is at the point (−1 + t, 4 − t, −1 + 2t) and the second

Pie

Answer:

Yes, the paths of the two particles cross.

Location of path intersection = ( 1 , 2 , 3)

Explanation:

In order to find the point of intersection, we need to set both locations equal to one another. It should be noted however, that the time for each particle can vary as we are finding the point where the <u>paths</u> meet, not the point where the particles meet themselves.

So, we can name the time of the first particle $T_F$ , and the time of the second particle $T_S$ .

Setting the locations equal, we get the following equations to solve for $T_F$ and $T_S$ :

$(-1 + T_F) = (-7 + 2T_S)$ Equation 1

$(4 - T_F) = (-6 + 2T_S)$ Equation 2

$(-1 + 2T_F) = (-1 + T_S)$ Equation 3

Solving these three equations simultaneously we get:

$T_F =$ 2 seconds

$T_S =$ 4 seconds

Since, we have an answer for when the trajectories cross, we know for a fact that they indeed do cross.

The point of crossing can be found by using the value of $T_F$ or $T_S$ in the location matrices. Doing this for the first particle we get:

Location of path intersection = ( -1 + 2 , 4 - 2 , -1 + 2(2) )

Location of path intersection = ( 1 , 2 , 3)

Why is it not advisable to sterilize clinical thermometer with boiling water

It will break. A clinical the emoter is designed to measure relatively small changes in temperature. The substance inside a clinical thermoset will expand or evaporate at boiling temperatures and break.
