Compare the gravitational force on a 4 kg

Physics
1 answer:
Eddi Din [679]3 years ago

Answer:

  • The gravitational force by the Earth on the object, and by the object on the Earth is

  • F = GMm/R²

  • = 6.674×10−11 m3⋅kg−1⋅s−2 × 6 × 10^24 kg × 44.5 kg/(6.4 × 10^6 m)²

  • = 435 N

<u>Please note that the ration between the gravitation force 435 and the mass 44.5</u>

  • should be gravitational acceleration

  • 435/44.5 = 9.78

  • I attribute the discrepancy between 9.78 and the usual 9.81 to rounding off in the

  • Earth's weight and radius.

The mass of the Moon is M / 81.3.

The radius of the Moon is R × 0.27.

The gravitational force on the moon would be

G(M/81.3)m/(R×0.27)² = 0.17×GMm/R²

The gravitational force on the moon is smaller by the factor of about 0.17.

arlik [135]

The statement 'establishing a high critical value in a statistical test is associated with more confidence' is TRUE.

<h3>What is statistical significance?</h3>

The statistical significance is a arbitrary value used to indicate that data collected can be used to confirm (or reject) my working hypothesis.

The most widely used value to measure the statistical significance is the p threshold.

In conclusion, the statement 'Establishing a high critical value when calculating the results of a statistical test means that a researcher will have more confidence in finding significance than when a lower critical value is established' is TRUE.

Answer:

3kg sledgehammer swung at 1.5 m/s

Explanation:

Small Sledgehammer:

Mass:3.0

Velocity:1.5

MASS×VELOCITY=MOMENTUM

3.0×1.5= 4.5 (momentum)

Large Sledgehammer:

Mass:4.0

Velocity:0.9

4.0×0.9=3.6 (momentum)

higher momentum is the smaller Sledgehammer.

Study the interaction of the light rays with the mediums. Classify the medium in each image as being transparent or opaque.
Tresset [83]

Answer:

a) transparent

b) transparent

c) opaque

Explanation:

In the first one, the light rays go completely through, so it is transparent.

The second one I'm not too sure about. It is refraction so it's going through a different material, but the fact that it went through makes me say transparent.

Last one, the light rays are reflecting off the surface so it's opaque.

Please feel free to correct me if I'm wrong. This is just my understanding
