Although most astronomers assume dark matter really exists, there is at least one other possible explanation for the phenomena attributed to dark matter. What is it?
It's possible that our understanding of how gravity behaves on galaxy-scales is inaccurate or lacking in some way.
What is dark matter in space?We surmise that dark matter exists based on its gravitational pull on visible matter. In order to rule out the idea that our comprehension of gravity is leading us to incorrectly infer the presence of dark matter, the majority of scientists believe it to be extremely unlikely that there is a problem with our knowledge of gravity. As long as it is too faint for us to perceive beyond the halo of our galaxy, astronomers regard dark matter to be "dark." If a human were to be hurled into the halo of our galaxy, they might end up being dark matter. An estimated 85% of the universe's mass is assumed to be made up of dark matter, a hypothetical type of stuff. Dark matter is so-called because it doesn't seem to interact with the electromagnetic field, which means it doesn't emit electromagnetic radiation like light or absorb electromagnetic radiation like it does. As a result, it is hard to detect. Numerous astrophysical observations support the existence of dark matter, including gravitational effects that cannot be described by the gravity theories currently in use without the presence of more matter than can be observed. Because of this, the majority of scientists believe that dark matter is prevalent in the universe and has greatly influenced its structure and evolution.

1. what is the electric force between a point charge and a point charge if they are separated by a distance of 5.0 cm? show your work.
-14.4 N is the electric force between a point charge and a point charge if they are separated by a distance of 5.0 cm.
The electrostatic force between two-point charges is given by:
[tex]F = K_{e}\frac{q1q2}{r^{2} }[/tex]
where,
[tex]K_{e}[/tex] is the Coulomb's constant
q1 and q2 are the two charges
r is the distance between them
In our problem, charge 1 is
[tex]q1=+2=+2.0 *10^{-6}C[/tex]
while charge 2 is
[tex]q2=-2=-2.0 *10^{-6}C[/tex]
and their distance is
r=5.0 cm=0.05 m
So, the electrostatic force between them is

The right answer is F= 3.59502N
According to Coulomb’s law if two point charges q1 and q2 are separated by a distance r then the magnitude of the force of repulsion or attraction between them is
F=k|q1| |q2|r2 where k=8.9876*109N.m2C2
What is Coulomb's law?
The product of the charges and the square of the distance between them determine the force of attraction or repulsion occurring in a straight line between two electric charges.
This is the strength of the force that each charge has on the other charge, according to Newton's third law. The symbol k as it is used here has nothing to do with any spring constants or Boltzmann's constant; it has to do with electrical forces!
In the event that charges q1 and q2 have the same sign (either they are both positive or negative), The force on each charge points away from the other charge and is mutually repelling.The force is reciprocal if the charges have opposite signs (one positive, one negative).
Each charge is attracted to the other by its own force.. This is illustrated in

If a giant molecular cloud is 59 pc in diameter and a shock wave sweeps through at 18 km/s, how long will it take the shock wave (in years) to sweep through the cloud?
The time it will take for the shock wave in years to sweep through the cloud is 3.2075 x 10⁷ years.
What is Velocity?Velocity is the directional speed of a moving object as an indicator of its rate of change in location as perceived from a certain frame of reference and measured by a specific time standard.
As it is known that one parsec is equal to 3.086×10¹⁶ meters. Therefore, the diameter of the molecular cloud is,
Diameter of the molecule = 59 pc
= 59 × 3.086×10¹⁶ meters
= 1.82074 × 10¹⁸ meters
= 1.82074 × 10¹⁵ kilometres
Given that the shock wave sweeps through at 18 km/s. And as it is known that velocity is the ratio of distance and time. Therefore, the time it will take for the shock wave to sweep through the molecule cloud is,
Velocity = Distance / Time
18 km/s = 1.82074 × 10¹⁵ km / Time
Time = 1.82074 × 10¹⁵ km / 18 km/s
t = 1.01152x10¹⁴ seconds
Since one year is equal to 31,536,000 seconds, therefore, the time in years is equal to,
t = 1.01152x10¹⁵ seconds / 31,536,000 seconds per year
t = 32,075,088.79 years

A 24. 0-mw (milli-watts) laser puts out a narrow cylindrical beam 2. 00 mm in diameter. what is the average rms e-field? n/c
A 24. 0-mw (milli-watts) laser puts out a narrow cylindrical beam 2. 00 mm in diameter. The average rms electric field is 2.82N/C.
The Average rms Electric Field is the square root of the mean value of electric field.
Given:
Power of beam = 24mW = 0.024W
Diameter of beam = 2mm = 0.002m
Radius of beam = 1mm = 0.001m
∴ Area Of beam = 22/7 × (radius)²
⇒ Area Of beam = 22/7 × (0.001)²
⇒ Area Of beam = 3.14 m²
∴ Intensity of Beam is the power per unit area where the beam spreads.
Intensity of Beam = Power / Area
⇒ Intensity of Beam = 0.024 / 3.14
⇒ Intensity of Beam = 0.075 W/m²
The average value of RMS for Electric field can be calculated by:
Erms = [tex]\sqrt{Intensity / (speed of light) (permmitivitty of medium)}[/tex]
Erms = 0.075 / 3 × 10⁸ × 8.85 × 10⁻¹²
