<h3><u>Answer;</u></h3>
  • A galaxy refers to all existing matter, energy, and space that is held together by gravity
  • A solar system is a collection of planets, their moons, and other objects in orbit around a central star.
<h3><u>Explanation;</u></h3>
  • <em><u>The universe contains many galaxies and solar systems.</u></em>
  • <em><u>A galaxy </u></em>is a huge collection of gas, dust, and billions of stars and their solar systems.  A galaxy is held together by gravity. The galaxy that contains the Earth and its solar system is called the Milky Way.
  • <u>Solar System</u> consists of the stars, the Sun, and its orbiting planets, including the Earth, along with numerous moons, asteroids, comet material, rocks, and dust.

State a Newtowns second law​
astraxan [27]

Answer:

the second law states that the force F is the product of an object's mass and its acceleration a: F = m * a. For an external applied force, the change in velocity depends on the mass of the object.

An elevator carrying a person of mass m is moving upward and slowing down. How does the magnitude f of the force exerted on the
V125BC [204]

The force f of the elevator on the man keeps reducing as the elevator keeps going up while the gravitational force mg keeps increasing moving upwards.

<h3>What is an elevator?</h3>

An elevator is an electrical device that lifts people up and down a tall building or structure.

for the elevator to go up, f > mg.

for the elevator to come down mg > f.

Analysis

since the force on the man is f = ma

where a is the acceleration of the elevator, then it means when a increases,  f will increase and when it decreases, f would decrease. slowing down means a, is decreasing going up and this reduces the force as the elevator keeps going up.

on the other hand, gravity acts faster on bodies that are slower in motion so since g, increases going up, mg would also increase.

When light in vacuum is incident at the polarizing angle (Brewster's angle) on a certain glass slab, the angle of refraction is
marysya [2.9K]

Answer:

Explanation:

θ( p ) + θ( r ) = 90  

θ (r) = angle of refraction and θ ( p ) is polarising angle.

given θ ( r ) = 31.8

θ ( p ) = 90 - 31.8 = 58.2 degree

ii ) Tanθ ( p ) = n ( refractive index ) = Tan 58.2 = 1.6
