Answer:
The arrows to the right of Earth should point up
Explanation:
The Earth acts as a huge magnetic dipole, oriented as its axis of rotation, with the North Pole located at the South geographic pole and the South pole located at the North geographical pole.
In a magnetic dipole, the lines representing the field go out from the north pole into the south pole.
This means that for the Earth, the field lines should go from south (which is the north magnetic pole) to north (which is the south magnetic pole): therefore, the arrows to the right of the Earth should point up as well as the line to the left.
The amount of sunlight received per square centimeter is different by 36 times less.
<h3>What is the speed of light?</h3>
A fundamental physical constant, typically abbreviated as c, the speed of light in a vacuum is significant in many branches of physics. 299792458 metres per second, or around 300000 kilometres per hour or 186,000 miles per hour, is the precise figure. The special theory of relativity states that the maximum speed at which ordinary matter, energy, or any signal containing information may move across space is given by the constant c.
Visible light is an example of electromagnetic radiation that moves at the speed of light. Light and other electromagnetic waves appear to move instantly for many practical uses, but their limited speed has dramatic implications over vast distances and particularly sensitive measurements. The starlight that can be seen from Earth has been out there for a very long time, allowing people to see far-off objects and learn about the evolution of the cosmos. It can take minutes to hours for signals to reach from Earth to a spacecraft when corresponding with far-off space missions. The absolute shortest communication latency between computers, to computer memory, and within a CPU is fixed in computing at the speed of light.

Answer:
125.09 Hz
Explanation:
Given : A person stands 5.20 from one speaker and 4.10 m away from the other speaker.
Distance between the speakers is 5.20 - 4.10 =1.10 m
We know that
For destructive interferences
n . λ / 2
where n =1,3,5,7....
Therefore difference between the speakers is
5.10 - 4.20 = 1 X 0.5 λ
λ = 2.2
Given velocity of sound is V = 344 m/s
Therefore frequency, f = 
= 
= 156.36 Hz
Now, the third lowest frequency is given by
λ = (5.20-4.10) X 5 X 0.5
= 2.75 m
Therefore frequency, f = 
= 
= 125.09 Hz
Therefore third lowest frequency is 125.09 Hz
Answer:
18.9 <em>N or </em><em>19</em><em> N </em>rounded
Explanation:
m = 0.145 kg
a = 130 m/s^2
F = ma = (0.145 kg)(130 m/s^2) = 18.9 <em>N</em>
When you're talking about gravity, it's easy to identify the equal
opposite forces.
Gravity ALWAYS produces an equal pair of opposite forces.
They both act between the centers of the two objects, one in
each direction.
Consider the equal pair of opposite gravitational forces between
you and the Earth. One force acts on you, and draws you toward
the center of the Earth. We call that force "your weight".
The other one acts on the Earth, and draws it toward the center
of you. Hardly anybody ever talks about that one, but the two
forces are equal ... your weight on Earth is equal to the Earth's
weight on you !
