A compass taken to Earth’s moon does not point in a specific direction on the moon. What is the most likely reason for the diffe

rence between how the compass works on Earth and on the moon? The moon lacks an atmosphere. The moon contains no rocks that have iron. The moon does not have a liquid core. The moon has no bodies of water.

Most likely, C. the Moon does not have a liquid core (this is what would create a magnetic field) is correct.

I hope this enough to help you!

It's thought that electric currents in Earth's liquid core are what creates Earth's magnetic field.  The moon does not have a liquid core.

The result is:  The moon's magnetic field is thousands of times smaller than Earth's.  And plus, the moon's magnetic field exists only in certain places, and there are large parts of the moon's surface where there is no magnetic field.  

So a compass would have to be very sensitive to do ANYTHING on the moon, and even then, it wouldn't be useful for indicating any particular direction.

katrin2010 [14]

Answer:

b

c

e

h

Explanation:

Note that the swing direction was not giving in the question and direction could be sideways (in a turn) or in a track or both

The question show something in common ...acceleration

So let's look at the statements and pick the correct ones

a is false while b is correct as the train is accelerating

c is correct. The train is accelerating even thou the speed could not be ascertained

d is false and not feasible as the train is accelerating

e is true as the train maybe moving at a constant speed in a circle

f is false. This could be constant velocity in a circle. Same as g (false)

h is true. It's accelerating

Suppose that you are standing on a train accelerating at 0.20g (where g is the acceleration due to gravity). What minimum coeffi
prisoha [69]

Answer:

0.2

Explanation:

The given parameters are;

The acceleration of the train, a = 0.2·g

The mass of the person standing on the train = m

Let μ represent the coefficient of static friction, we have;

The force acting on the person, F = m × a = m × 0.2·g

The force of friction acting between the feet and the floor, F_f = m·g·μ

For the person not to slide we have;

The force acting on the person = The force of friction acting between the feet and the floor

F = F_f

∴ m × 0.2·g = m·g·μ

From which we get;

0.2 = μ

The coefficient of static friction that must exist between the feet and the floor if the person is not to slide, μ = 0.2.
