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.

a hot iron bar is placed 100ml 22C water. the water temperature rises to 32C. how much heat did the water gain and how much heat
Sergeu [11.5K]

Answer:

  • Water gained: 10
  • Iron lost: -10

Explanation:

Given: Hot iron bar is placed 100ml 22C water, the water temperature rises to 32C

To find: How much heat the water gain, how much heat did the iron bar lost

Formula:Q = change T x C x M

Solve:

<u>How much heat water gained</u>

Initial heat = 22, then rose to 32. To find how much heat the water gained, simply subtract the current heat by the initial heat.

                                              32 - 22 = 10

The water gained 10 amounts of heat.

<u>How much heat Iron lost</u>

Current heat = 32, then dropped to 22. To find how much heat the Iron lost, simply subtract the initial heat by the current heat.

                                                   22 - 32 = -10

The Iron lost -10 amounts of water.

Explain any two areas affected by migration​
mel-nik [20]

Answer:

<h2>Migration is affected by various factors like age, sex, marital status, education, occupation, employment etc. Age and sex are main demographic factors that affect the migration. Men, generally, migrate to other places quite often though there are more women who migrate to husbands' places after marriage.</h2>

Calculated the measurement uncertainty for Kinetic Energy when :mass = 1.3[kg] +/- 0.4[kg]velocity= 5.2 [m/s] +/- 0.2 [m/s]KE= 1
andriy [413]

Answer:

\rm KE\pm \Delta KE = 17.6\pm 6.8\ J.

Explanation:

<u>Given:</u>

  • Mass, \rm m\pm\Delta m = 1.3\pm 0.4\ kg.
  • Velocity, \rm v\pm \Delta v = 5.2\pm 0.2\ m/s.

where,

\rm \Delta m,\ \Delta v are the uncertainties in mass and velocity respectively.

The kinetic energy is given by

\rm KE = \dfrac 12 mv^2 = \dfrac 12 \times 1.3\times 5.2^2=17.576\approx 17.6\ J.

The uncertainty in kinetic energy is given as:

\rm \dfrac{\Delta KE}{KE}=\dfrac{\Delta m}{m}+\dfrac{2\Delta v}{v}\\\dfrac{\Delta KE}{17.6}=\dfrac{0.4}{1.3}+\dfrac{2\times 0.2}{5.2}\\\dfrac{\Delta KE}{17.6}=0.384\\\Rightarrow \Delta KE = 17.6\times 0.384 = 6.7854\ J\approx6.8\ J\\\\Thus,\\\\KE\pm \Delta KE = 17.6\pm 6.8\ J.
