Physics
1 answer:
damaskus [11]3 years ago
7 0

Answer:

Hadley cells

Explanation:

Formation of Convection Currents

Atmospheric convection currents are global patterns of air movement that are initiated by the unequal heating of Earth. Hadley cells- the convection currents that cycle between the equator and 30˚ north and south.

What is the kinetic energy k of an electron with momentum 1.05×10−24 kilogram meters per second?
fiasKO [112]
Momentum = mv
where m is the mass of an electron and v is the velocity of the electron.

v = momentum ÷ m
   = (1.05×10∧-24)÷(9.1×10∧-31) = 1,153,846.154 m/s

kinetic energy = (mv∧2)÷2
                       = (9.1×10∧-31 × 1,153,846.154∧2) ÷2
                      = (1.21154×10∧-18) ÷ 2
                      = 6.05769×10∧-19 J

A block of 250-mm length and 54 × 40-mm cross section is to support a centric compressive load P. The material to be used is a b
musickatia [10]

Answer:

P = 17.28*10⁶ N

Explanation:

Given

L = 250 mm = 0.25 m

a = 0.54 m

b = 0.40 m

E = 95 GPa = 95*10⁹ Pa

σmax = 80 MPa = 80*10⁶ Pa

ΔL = 0.12%*L = 0.0012*0.25 m = 3*10⁻⁴ m

We get A as follows:

A = a*b = (0.54 m)*(0.40 m) = 0.216 m²

then, we apply the formula

ΔL = P*L/(A*E)  ⇒ P = ΔL*A*E/L

⇒  P = (3*10⁻⁴ m)*(0.216 m²)*(95*10⁹ Pa)/(0.25 m)

⇒  P = 24624000  N = 24.624*10⁶ N

Now we can use the equation

σ = P/A

⇒  σ = (24624000  N)/(0.216 m²) = 114000000 Pa = 114 MPa > 80 MPa

So σ > σmax  we use σmax

⇒  P = σmax*A = (80*10⁶ Pa)*(0.216 m²) = 17280000 N = 17.28*10⁶ N

.Which equation represents the most accurate model of cellular respiration? Note: C6H12O6 is sugar.
Shkiper50 [21]

The equation that most accurately represents the model of cellular respiration is: C6H12O6 (sugar) + 6O2 (oxygen) = 6CO2 (carbon dioxide) + 6H2O (water) + energy.

<h3>CELLULAR RESPIRATION:</h3>

Cellular respiration is the process whereby living organisms obtain energy by breaking down food molecules in their cells.

The process of cellular respiration breaks down sugar molecules (glucose) in the presence of oxygen to produce carbon dioxide and water as products, as well as energy in form of ATP.

Therefore, the equation that most accurately represents the model of cellular respiration is: C6H12O6 (sugar) + 6O2 (oxygen) = 6CO2 (carbon dioxide) + 6H2O (water) + energy.
