What's inside a nucleus and makes RNA to make proteins

Physics
1 answer:
WINSTONCH [101]3 years ago

RNA polymerase

(After the RNA is transcribed and processed, it leaves the nucleus, going to the ribosome where tRNA translates it into an amino acid chain, which then folds into a protein)

Your low-flow showerhead is delivering water at 1.2×10−4m3/s, about 2.0 gallons per minute.
Oksanka [162]

To solve this problem it is necessary to apply the fluid mechanics equations related to continuity, for which the proportion of the input flow is equal to the output flow, in other words:

Q_1 = Q_2

We know that the flow rate is equivalent to the velocity of the fluid in its area, that is,

Q = VA

Where

V = Velocity

A = Cross-sectional Area

Our values are given as

Q_2 = 1.2*10^{-4}m^3/s

d = 0.021m

r = \frac{0.021}{2} = 0.0105m

Since there is continuity we have now that,

V_1A_1 = Q_2

V_1A_1 = 1.2*10^{-4}

V_1 = \frac{1.2*10^{-4}}{A_2}

V_1 = \frac{1.2*10^{-4}}{\pi r^2}

V_1 = \frac{1.2*10^{-4}}{\pi (0.0105)^2}

V_1 =0.347m/s

Therefore the speed of the water's house supply line is 0.347m/s

Two stars, both of which behave like ideal blackbodies, radiate the same total energy per second. The cooler one has a surface t
Blizzard [7]

Answer:

Explanation:

Let hotter star has surface area of A . The cooler star would have surface area 9 times that of hotter star ie 9A , because its radius is 3 times hot star. Let temperature of hot star be T ₁.

Total radiant energy is same for both the star

Using Stefan's formula of black body radiation,

For cold star E = 9A x σ T⁴

For hot star E = A x σ T₁⁴

A x σ T₁⁴ = 9A x σ T⁴

T₁⁴ = (√3)⁴T⁴

T₁ = √3T .

b )

Let the peak intensity wavelength be λ₁ and λ₂ for cold and hot star .

As per wein's law

for cold star , λ₁ T = b ( constant )

for hot star  λ₂ √3T = b

dividing

λ₁ T / λ₂ √3T = 1

λ₂  / λ₁ =  1 / √3

Which of the following actions in a car cause it to accelerate? Select all that apply.
Oksi-84 [34.3K]

Answer:

Option (b) will be correct answer for accelerating the car

Explanation:

For accelerating the car we have to speed up the car

In option (b) it is given that stepping on the gas pedal to speed up the car so it is correct answer

In option (c) it is given that pressing the pedal to slow down the car it is a case of deceleration so it is a incorrect statement.

In option (d) it is given that speed is constant at curved path so acceleration will be zero because if there is no change in velocity then acceleration will be zero
