Answer:

The correct option are

A. Clouds

E. Motion of tech tectonic plates

Explanation:

The earth moon doesn't have an atmosphere because of it is relatively too small and it's magnetic field is not strong.

It instead has a dust cloud which researchers studying data from the LADEE (Lunar Atmosphere and Dust Environment Explorer) spacecraft have discovered that the airless moon is surrounded by a thin, asymmetrical dust cloud caused by the high-speed impacts of dust particles from comets.

The Moon is small and should have retained its internal heat only for a short time. Thus, astronomers suspect that it cooled quickly.

The Moon's Mantle, too cool to move easily, has no convection and no active tectonic plate motions, due the Moon's smaller size and cooler interior than Earth.

Even all other options such as magnetic field, gravity, imparter carter and rocks created by lava flow, they occur on moon but they relatively less effect on the moon compare to the earth, this might due to the small size of the moon

E.g

Value of gravity on earth is 9.81m/s², it value on moon is 1.62m/s²

The magnetic strength on the moon is weak. Earth's magnetic field at its surface ranges from 25 to 65 microteslas while the moon today does not possess a global magnetic field, but some billions years ago, the moon's magnetic field once ranged in strength from 20 to 110 microtesla.

Answer:

The correct option is;

E. motion of tectonic plates.

Explanation:

The Moon is formed from the Earth, and so have similar composition. However, the smaller size of the moon as well as the low temperature of the Moon's mantle compared to the interior of the earth, contribute the state of the Moon having no active tectonic plate motion and no convection.

The convection in the mantle, drives Earth's tectonic plate motions. The mantle within Earth moves at a rate of some centimeters annually, while the Moon, geologically is a dying world.

antoniya [11.8K]

Answer:

r=5.278\times 10^{-4}\ m

Explanation:

Given that:

  • magnetic field intensity, B=0.07\ T
  • kinetic energy of electron, KE=1.2\ eV= 1.2\times 1.6\times 10^{-19}\ J= 1.92\times 10^{-19}\ J
  • we have mass of electron, m=9.1\times 10^{-31}\ kg

<em>Now, form the mathematical expression of Kinetic Energy:</em>

KE= \frac{1}{2} m.v^2

1.92\times 10^{-19}=0.5\times 9.1\times 10^{-31}\times v^2

v^2=4.2198\times 10^{11}

v=6.496\times 10^6\ m.s^{-1}

<u>from the relation of magnetic and centripetal forces we have the radius as:</u>

r=\frac{m.v}{q.B}

r=\frac{9.1\times 10^{-31}\times 6.496\times 10^6 }{1.6\times 10^{-19}\times 0.07}

r=5.278\times 10^{-4}\ m

If the frequency of q of a trait is 0.4, what is the frequency of p?
lianna [129]
In genetic traits, p and q represent the relative probabilities of the two alleles manifesting. If these two are the only options (ex. a dominant one and a recessive one), then the probabilities of both must sum up to 1. In this case, since we are given that q = 0.4, then p + q = 1, p + 0.4 = 1, and p = 0.6.

A race car has a centriple acceleration of 15.625 m/s as it goes around a curve if the curve is a circle with radius 40 m what’s
Elanso [62]

Answer:

25 m/s

Explanation:

Centripetal acceleration is the square of the tangential velocity divided by the radius.

a = v² / r

15.625 m/s² = v² / (40 m)

v² = 625 m²/s²

v = 25 m/s

The speed of the car is 25 m/s.
