Earth's protective magnetic bubble, called the magnetosphere, deflects most solar particles, but in the absence of atmospheric layer, Polyethylene is a good shielding material because it has high hydrogen content, and hydrogen atoms are good at absorbing and dispersing radiation.
The Earth’s atmospheres are kept in place by gravity. The air near the ground is pulled on by gravity and compressed by the air higher in the sky. This causes the air near the ground to be denser and creating different layers with different qualities in which are the atmosphere.
Hope that helps ^^
At what angle torque is half of max
Answer:
<em>A</em><em> </em><em>property of matter by which it remains at rest or in motion in the same straight line unless acted upon by some external force</em>
10 m/s² to the left.

<u>Given: </u>
- The mass of a stuffed bear = 200 grams = 0.2 kg.
- The mass of a boy = 25 kg.
- The mass of a girl = 20 kg.
- A boy pulls to the right with a 15 N force.
- A girl pulls to the left with a 17 N force.
<u>Question:</u>
What the acceleration of the bear is?
This is the case for implementing Newton's second law, i.e., 'the resultant force is proportional to the acceleration'. If we also use SI units then 'the resultant force is equal to the product of the mass and the acceleration'.
- The net force, i.e., is the resultant of all forces acting on an object, measured in newtons (kgm/s²).
- The mass measured is kilograms.
- The acceleration measured in m/s².
Let's calculate the net force.
Referring to the horizontal axis marked a positive to the right, then
A negative sign indicates that the bear is moving to the left.
We continue to calculate the bear's acceleration. Remember, the mass that is applied is the mass of the bear that is accelerating.
Thus, the magnitude and direction of the acceleration is

Supermassive black holes astronomers believe to be driving activity in the centers of galaxies.
A galaxy is a device of stars, stellar remnants, interstellar gas, dust, and darkish count, sure together with the aid of gravity. The phrase is derived from the Greek galaxies, actually 'milky', a connection with the Milky manner galaxy that incorporates the solar system. Galaxies, averaging an envisioned a hundred million stars, range in length from dwarfs with much less than one hundred million stars, to the most important galaxies acknowledged – supergiants with one hundred trillion stars, each orbiting its galaxy's center of mass. most of the mass in a typical galaxy is within the form of a darkish count number, with just a few percentages of that mass seen within the form of stars and nebulae. Supermassive black holes are a commonplace feature in the centers of galaxies.
the gap among galaxies is filled with tenuous gasoline (the intergalactic medium) with an average density of much less than one atom consistent with a cubic meter. most galaxies are gravitationally prepared into businesses, clusters, and superclusters. The Milky way is part of the nearby organization, which dominates alongside the Andromeda Galaxy.
