(sorry if this is late)

Explanation:

Rest of the answers.

As solar wind approaches Earth, what happens to the charged electrons?

They are deflected as Earth’s magnetic field exerts force on them.

Which best describes how energy transferred from an electron in the solar wind compares with energy absorbed by an electron in the oxygen atom?

equal to

Which statement is accurate about how the aurora borealis is formed?

When the electrons fall to a lower energy state, they release energy as electromagnetic radiation, light.

How does the energy in the light of the aurora borealis compare to the energy as an excited electron returns to its original energy level?

equal to

During the formation of the aurora borealis, the electrons in an atom experience a change in energy levels. Which statement about this change is accurate?

First, the electron absorbs energy to move to a higher energy level.

The only two forces acting on a body have magnitudes of 20 N and 35 N and directions that differ by 80°. The resulting accelerat
pantera1 [17]

Answer:

b) 2.2 kg

Explanation:

Net force acting on an object is the sum of the  two forces acting on the body.

The net force is calculated using the parallelogram law of vectors.

F =\sqrt{{A^{2}} + B^{2}+2 A B cos \theta}

Here A = 20 N , B = 35 N and θ =80°

Net Force = F = 43.22 N

Acceleration = a = 20 m/s/s

Since F = ma, m = F/a = 43.22 / 20 = 2.161 kg = 2.2 kg

What evidence contradicts the theory that moving two-ton stones was physically impossible for the egyptians, and must have been
SOVA2 [1]
Archaeological evidence shows that Egyptians worked together to build the pyramids. Remains of quarries and ancient tools suggest that large slabs were created from rock beds. The slabs were placed on sleds and pulled to the building site. To make this process easier, men most likely poured oil on the roadway. This process is depicted in tomb paintings that date back to 1900 BCE.

Which of the following examples accurately describes an object that is accelerating?
NemiM [27]
"Acceleration" doesn't mean "speeding up".
It means ANY change in speed OR direction of motion.

A). The race car is moving at 150 mph.  Speed isn't changing, and we don't
know anything about its direction.  No evidence of acceleration there.

B).  A sailboat moves west, then north. 
It changed direction.  During the time that it was sailing
on a curve or around a corner, it was accelerating.

C).  A train half way between New York and Houston.
We don't know anything about its speed OR direction right now.
No evidence of acceleration there.

D).  A book sitting motionless.
Its speed is zero.  We know for a fact that its speed and direction
are not changing. So there is definitely no acceleration here.
