In a nuclear power plant, uranium atoms ______
A. Combine and give off heat energy
B. Split and give of heat energy
C. Burn and give of heat energy
D. Split and give off electrons
Answer:
All nuclear power plants use nuclear fission, and most nuclear power plants use uranium atoms. During nuclear fission, a neutron collides with a uranium atom and splits it, releasing a large amount of energy in the form of heat and radiation. More neutrons are also released when a uranium atom splits.
two charges create 8.00 N of electric force on each other. if you increase their distance to twice its original value, how much electric force do they exert on each other
Answer:
2.00 (right on acellus)
Explanation:
doubling the distance between two charges makes F (8.00) quarter, so you would just do 8.00*1/4

A set of charged plates have an
area of 8.22*10^-4 m^2 and
separation 2.42*10^-5 m. The
plates are charged with
5.24*10^-8 C. What is the
potential difference V between
the plates?
(Unit = V)
pls hurry <3
Answer:
175
Explanation:
its for Acellus
The potential difference is V=1.743*10^-7
The voltage is generally referred to as the electric potential difference and it can be measured using a voltmeter. The electrical potential difference between the two plates is expressed as q=CV.
CALCULATION
we know,
q=CV
q={EA/d}*V
here q= 5.24*10^-8C
A=8.22*10^-5m^2
d=2.42*10^-8m
therefore , C={( 8.85*10^-12)*(8.22*10^-5)}/(2.42*10^-8)
C=3.006*10^-1
q=CV
q/C=V
V=1.743*10^-7

If two proton approach each other with speed of 400m\s and 450m\s respectively what is the total momentum of the two particle system
Answer: [tex]83.65\times 10^{-27}\ kg.m/s[/tex]
Explanation:
Given
The velocities of the protons are 400 m/s and 450 m/s
Mass of the Proton is [tex]m=1.673\times 10^{-27}\ kg[/tex]
Since they travel in the opposite direction, therefore, their momentum cancels out each other.
Momentum is the product of mass and velocity
[tex]\therefore m(450-400)\\\Rightarrow 1.673\times 10^{-27}\times 50\\\Rightarrow 83.65\times 10^{-27}\ kg.m/s[/tex]
The direction of momentum is in the direction of proton having 450 m/s velocity.

i want to now why volcanoes erupt
Answer:
Deep within the Earth it is so hot that some rocks slowly melt and become a thick flowing substance called magma. Since it is lighter than the solid rock around it, magma rises and collects in magma chambers. Eventually, some of the magma pushes through vents and fissures to the Earth's surface.
Explanation:
Explanation:
Volcanoes erupt when molten rock called magma rises to the surface. Magma is formed when the earth's mantle melts. ... If magma is thick, gas bubbles cannot easily escape and pressure builds up as the magma rises. When the pressure is too much an explosive eruption can happen, which can be dangerous and destructive.

The edge effect in habitats are caused by:
A. habitat fragmentation
B. biological magnification
C. eutrophication
D. destruction of habitat
The edge effect in habitats is caused by habitat fragmentation. Therefore, option A is correct.
Habitat fragmentation refers to the process by which large, continuous habitats are divided into smaller, isolated fragments due to human activities or natural events. It occurs when natural landscapes are altered or disrupted. It results in the fragmentation of once-continuous habitats into smaller patches.
This fragmentation can happen through various means, such as the construction of roads, urban development, agriculture, deforestation, or natural events like wildfires or floods.

Two parallel plates of area 7.34 x 10^-4 m^2 have 5.83 x 10^-8 C of charge placed on them. A 6.62 x 10^-6 C charge q1 is placed between the plates. What is the magnitude of the electric force on q1? Hint: How is force related to the field? (Unit = N)
Answer:
* if the two plates have the same charge sign F_net = 0
*if one plate is positive and the other is negative F_net = 59.4 N
Explanation:
The electric field created by a parallel plate is
E = [tex]\frac { \sigma }{2 \epsilon_o }[/tex]
where sigma is the charge density
σ = Q / A
we substitute
E = [tex]\frac{Q}{A \ 2 \epsilon_o }[/tex]
E = [tex]\frac{ 5.83 \ 10^{-8} }{7.34 \ 10^{-4}\ 2 \ 8.5 \ 10^{-12} }[/tex]
E = 4.487 10⁶ N / C
the electric force is
F = E / q
in this force it is a vector, so if the charges are of the same sign they repel and if they are of the opposite sign they attract. In this case, the test load is between the two plates that have the same load sign, so the forces are in the opposite direction.
* if the two plates have the same charge sign
F_net = F₁ - F₂
F_net = q (E₁ -E₂)
since the electric field does not depend on the distance
E₁ = E₂
in consecuense
F_net = 0
In a more interesting case
*if one plate is positive and the other is negative
F_net = F₁ + F₂
F_net = q (E₁ + E₂) = 2 q E₁
F_net = 2 6.62 10⁻⁶ 4.487 10⁶
F_net = 59.4 N
net force goes from positive to negative plate

A wire carries a current of 6.52 A in a direction that makes an angle of 44.8 degrees with the direction of a magnetic field of strength 0.258 T. What is the magnetic force on a 3.61 m length of wire
Answer:
[tex]F=4.27N[/tex]
Explanation:
From the question we are told that:
Current [tex]I = 6.52 A[/tex]
Angle [tex]\theta= 44.8 \textdegree[/tex]
Magnetic field [tex]B= 0.258 T.[/tex]
Length [tex]l=3.61m[/tex]
Generally the equation for Magnetic force F is mathematically given by

In a certain circuit the number of electrons passing a given point in 3 seconds is 6 x 1014 electrons. What is the current flow in this circuit? (Show all work, including substitution with units)
Answer:
Current = 0.000032 Amperes
Explanation:
Given the following data;
Time, t = 3 seconds
Number of electrons = 6 * 10^14 electrons
Conversion:
First of all, we would convert the number of electrons to charge.
Coulombs = electron charge ÷ 6.2415 * 10^18
Coulombs = (6 * 10^14) ÷ (6.2415 * 10^18)
Coulombs = 0.000096 Coulombs
To find the current;
Mathematically, quantity of charge is given by the formula;
Quantity of charge, Q = current * time
Substituting into the formula, we have;
0.000096 = current * 3
[tex] Current = \frac {0.000096}{3} [/tex]
Current = 0.000032 Amperes
