What happens to the force between charged and uncharged objects as the distance between them decreases?
Answer:Thus, if each of the charges were reduced by one-half, the repulsion would be reduced to one-quarter of its former value. Also In electrostatics, the electrical force between two charged objects is inversely related to the distance of separation between the two objects. ... And decreasing the separation distance between objects increases the force of attraction or repulsion between the objects.
Hope this helps have a awesome night/day❤️✨
Explanation:
Nothing, until those two objects physically touch each other; contact aligns polarity among the now single shared mass.
(Your question never states if both objects are unique or similar polar charges, so I just assumed they were both neutral objects existing within an electric field.)
So a better question would then be, what is gravity’s relationship with an electric field?
You could solve this with the following: confine the electric field’s volume to a set variable (never increasing nor decreasing in size or shape); density is variable and easily definable. This creates the limit to build upon. This density has to be fluid and has electron mass (full of electrons at rest mass, so with substance but no movement). Within, create a closed system (the hard part in this equation; outside interference like ambient light will eschew results) where each variable of kinetic energy then is accounted for or measurable (including heat and light, and the physical movement of the two objects)
Determine the mass for both objects, calculate gravity for both and each body’s inertia on the other as a sum over distance. record results. Polarity is shared across the masses until there is no longer inertia (one mass or contact).

A proton moves perpendicularly to a magnetic field that has a magnitude of 4.20 x 10-2 T. What is the speed of the particle if the magnitude of the magnetic force on it is 2.40 x 10-14 N?
Answer:
V=3.57 × 10^6 m/s
hope it is helpful..
The speed of the proton in the magnetic field is 3.57×10⁶ m/s.
To determine the speed of the proton, we need to know about the magnetic force experienced by a charged particle in a magnetic field.
What is the magnetic force on a charge particle in a magnetic field?From lorentz law, the magnetic force on a charge particle is given asF=q×v×B
where, q= charge of the particle
v= speed of the particle
B= magnetic field
What will be the speed of the charge particle, proton, if the magnetic field and force are given?Magnetic force(F)= q×v×Bv=F/(q×B)
Here, B= 4.20×10⁻²TF=2.40×10⁻¹⁴N
q= 1.6×10⁻¹⁹C
Then, v= 2.40×10⁻¹⁴/ ( 4.20×10⁻²× 1.6×10⁻¹⁹)
= 3.57×10⁶ m/s.
Thus, we can conclude that the speed of the proton in the magnetic field is 3.57×10⁶ m/s.

Which location, 23 degrees or 48 degrees would experience the same earthquake at stronger intensity?Explain why.
Answer:
48 degress
Explanation:
An earthquake causes many different intensities of shaking in the area of the epicenter where it occurs. So the intensity of an earthquake will vary depending on where you are. Sometimes earthquakes are referred to by the maximum intensity they produce. In the United States, we use the Modified Mercalli Scale. Earthquake intensity is a ranking based on the observed effects of an earthquake in each particular place. Therefore, each earthquake produces a range of intensity values, ranging from highest in the epicenter area to zero at a distance from the epicenter.

A police siren has a frequency of 340.0 Hz when the car is stationary and the temperature is 20°C. The police car at point S moves to the right with a speed of 22.0 m/s.
a. What frequency does observer A hear?
b. What frequency does observer B hear?
c. Suppose observer A is moving toward the stationary police car. What is the speed of observer A if the frequency heard is 369 Hz?
Answer:
a) 361.7 Hz
b) 318.1 Hz
c) 29.3 m/s
Explanation:
a) Speed of sound in 20 degrees celcius is 343 m/s.
Use v=wavelength*frequency to find wavelength.
343=wavelength*340
wavelegth=1.009 meters
Relative speed of waves to observer A = 343+22 = 365 m/s
Plug it back in.
365=1.009*F
F=361.7 Hz
b) Relative speed of waves to observer B = 343-22 = 321 m/s
Plug it back in.
321=1.009*F
F=318.1 Hz
c) STATIONARY CAR, so 369Hz=v/1.009. v=372.3, 372.3-343=29.3m/s!

Given that,
One dog pulls the chew toy with 64 N (E) and the other pulls the chew toy with 31 N [W].
We need to find the net force acting on the chew toy. Let East be taken positive and west be taken negative. So,
[tex]F_{net}=+64+(-31)\\\\=33\ N[/tex]

I can't do PEMDAS to save my life can someone show me the correct way to solve with work?
Answer:
[tex]5.12\:\text{m/s}[/tex]
Explanation:
From the conservation of momentum, the total momentum of the system before and after the collision must be the same. Therefore, let the momentum of Homeboy Joe be [tex]p_b[/tex] and let the mass of Homegirl Jill be [tex]p_j[/tex]. We can write the following equation:
[tex]p_{bi}+p_{ji}=p_{bf}+p_{jf}[/tex], where subscripts [tex]i[/tex] and [tex]f[/tex] represent initial and final momentum respectively.
The momentum of an object is given by [tex]p=mv[/tex].
Therefore, we have:
[tex]m_{b}v_{bi}+m_{j}v_{ji}=m_{b}v_{bf}+m_{b}v_{jf}[/tex] (some messy subscripts but refer to the values being plugged in you're confused what corresponds with what).
Plugging in values, we have:
[tex]99.5\cdot 6.65 + 68.8\cdot (-1.10)=99.5\cdot 2.35+ 68.8\cdot v_{jf}[/tex].
Solving, we get:
[tex]v_{jf}=\frac{99.5\cdot 6.65+68.8\cdot (-1.10)-99.5\cdot2.35}{68.8},\\v_{jf}=5.11875,\\v_{jf}\approx \boxed{5.12\:\text{m/s}}[/tex].
It's important to note that velocity is vector quantity, so the negative velocity assigned to Jill simply implies she is moving at [tex]1.10\:\text{m/s}[/tex] in the opposite of Joe's direction. After the collision, she is now moving [tex]5.12\:\text{m/s}[/tex] in the same direction that Joe was initially moving, due to Joe's relatively large mass and initial velocity.

A box has a mass of 6.0 kg. What is its weight on the mars, where the acceleration due to
gravity is 0.38 times that on Earth? *
Answer:
The weight of the box is 22.38 N.
Explanation:
The weight (W) of the mass is given by:
[tex] W = mg [/tex]
Where:
m: is the mass of the box = 6.0 kg
[tex]g_{m}[/tex]: is the acceleration due to gravity of mars
Since the acceleration due to the gravity of mars is 0.38 times that on Earth we have:
[tex]g_{m} = 0.38g_{E} = 0.38*9.81 m/s^{2} = 3.73 m/s^{2} [/tex]
Hence, the weight of the mass is:
[tex] W = mg = 6.0 kg*3.73 m/s^{2} = 22.38 N [/tex]
Therefore, the weight of the box is 22.38 N.

that is a difference between a law and a hypothesis?
A law describes how two variables affect each other, but a hypothesis only discusses one variable.
A law must be testable so that it can be proven, but a hypothesis is an untestable explanation.
A hypothesis includes an explanation for why two variables affect each other, but a law only describes how they
affect each other
A hypothesis may or may not be testable, but a law is an untestable explanation of why two variables affect each
other and cannot be proven
Answer:
A hypothesis is a limited explanation of a phenomenon; a scientific theory is an in-depth explanation of the observed phenomenon.
A law is a statement about an observed phenomenon or a unifying concept, according to Kennesaw State University. ... However, Newton's law doesn't explain what gravity is, or how it works.

As a geologist, you come across a landscape with a massive fault zone that
produces a lot of large earthquakes but has no volcanoes. What type of plate
boundary is this? What are the movements of plates there? Where is this type
of boundary found in California?

Which can make 4 covalent bonds? Carbon, Silicon, or both?
Answer:
I would say both
Explanation:
Each silicon atom has four valence electrons which are shared, forming covalent bonds with the four surrounding Si atoms.
Carbon contains four electrons in its outer shell. Therefore, it can form four covalent bonds with other atoms or molecules. The simplest organic carbon molecule is methane (CH4), in which four hydrogen atoms bind to a carbon atom (Figure 1).
