Earth has four motions in its movement through space, rotation, revolution, processional, and solar motion, which two are of any
Anna007 [38]

Answer:

rotation and revolution

Explanation:

out of the four motions the earth is subject to which are: rotation about its axis, revolution around  the Sun, processional motion (a slow conical movement ) of the axis, and the solar motion (this refers to the

movement of the whole solar system with space),  only two are of any

importance to meteorology as this two causes changes in weather and seasons. The first motion is rotation. Earth rotates on its axis

once every 24 hours. One-half of the Earth’s surface is

therefore facing the Sun at all times. The second motion of Earth is its revolution around  the Sun. The revolution around the Sun and the earth tilt on its axis are responsible for changes in seasons. The Earth

makes one complete revolution around the Sun in

approximately 365 1/4 days.

PLZ HELPPPPP!! i'll give brainliest
kati45 [8]

Answer:

12N to the right.

Explanation:

There is a force of 12N upwards and a force of 12N downwards: these cancel out.

Assign a negative value to forces towards the left, and a positive value to the forces towards the right: -3N and +15N

Combine them: -3N+15N = 12N

The net force has a magnitude of 12N, and since our answer was positive, it acts towards the right.

How can a person detect infrared rays without an instrument?
natita [175]
So we want to know how can we detect infrared rays without an instrument. Infrared rays or heat, are a part of electromagnetic spectrum. We have specialized nerve cells in our skin called thermoreceptors that can detect differences in temperature that are produced by infrared part of EM spectrum.

A solid cylinder of uniform density of 0.85 g/cm3 floats in a glass of water tinted light blue by food coloring.
SVEN [57.7K]

Each side has to have at least 44 horses

F61160 N. This is further explained below.

<h3>What is the force?</h3>

Generally, We are only interested in the component that operates horizontally since the vertical components all cancel each other out. The pressure difference works on the hemisphere to generate a normal force all over the surface, but we are only concerned with that force's horizontal component. This may be determined by supposing the hemispheres to be two flat circular plates of the same radius as the hemispheres that have been forced together.

Therefore, force is equal to pressure multiplied by area, which is

F= (970 -15 )( * (0.45 m)2)

F=60754 N for each side.

Therefore, each side has to have at least 44 horses

44* 1390 = 61160 N
