Why does the gravitational field strength increase with latitude

1 answer:

4 0

The second major reason for the difference in gravity at differentlatitudes is that the Earth's equatorial bulge (itself also caused by centrifugalforce from rotation) causes objects at the Equator to be farther from the planet's centre than objects at the poles.

The initial momentum and the vertical and horizontal component

tamaranim1 [39]

Momentum = mass * velocity

p = mv

p = 1.5 kg * 40 ms^-1

p = 60 kgm/s

To find components of a vector:

px = p * cos(theta)
px = 60 * cos(30)
px = 51.96 = 52 (rounded to two significant digits)

py = p * sin(theta)
py = 60 * sin(30)
py = 30

He initial momentum is 60kgm/s
The horizontal component is 52 kgm/s
The vertical component is 30 kgm/s

A crane raises a 12,000 N marble sculpture at a constant velocity onto a pedestal 1.5 m above the ground outside an art museum.

Simora [160]

For the work, applicate formula:

$\boxed{\boxed{\green{\bf{W = F\times d}}}}$

According our data:

Replacing:

W = 12000 N * 1,5 m

Resolving:

W = 18000 J

The work done is <u>18000 Joules.</u>

How do the densities of the jovian and terrestrial planets compare?

timofeeve [1]

Hello

The jovian density is $1.33~g/cm^3$ , while the density of terrestrial planets is much higher. For instance, the earth's density is $5.51~g/cm^3$ . The reason of this difference is in the different chemical composition: while jupiter is made of gas (mainly hydrogen), with lower density, while the terrestrial planets are made of solid and liquid, with compounds of higher density.

The gravitational force between Earth and the Sun is a two-way force. Both the planet and the Sun attract each other. However, E

Ymorist [56]

The correct choice would be

B) The Sun’s mass is much greater than Earth’s

The sun as we know has greatest mass in our solar system and lighter objects tends to orbit around the heavier objects. the mass of earth is very much smaller as compared to that of the sun. hence the earth orbits around the sun due to the force of gravitational attraction between the two objects.
