CALCULATE ELECTRIC POTENTIAL
URGENT PLEASE HELP ASAP
Answers
Given two charges, \(q_2 =2 \times 10^{-6} \ C\) and \(q_3 =-2 \times 10^{-6} \ C\) we are asked to calculate the the Electrical Potential at a point, "P."
The distance from point "P" to charge 2 is \(r_{p2}=0.12 \ m\)
The distance from point "P" to charge 3 is \(r_{p3}=0.05 \ m\)
What is Electric Potential?
Electric potential is a measure of an electric fields ability to alter/change the potential energy of a charge.
Electric potential can be solved in various ways, in this case we are talking about point charges. So we can calculate the electric potential at point "P" using the following equation,
\(\boxed{V=\frac{k_eq}{r}}\)
Where,
=>\(k_e=8.99 \times 10^9 \ \frac{Nm^2}{C^2}\) which is Coulomb's constant
=> q is the charge (in Coulombs)
=> r is the distance (in meters) from the charge to point you want to know the electric potential at.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
\(V_{tot}=V_2+V_3 \Longrightarrow V_{tot}=\frac{k_eq_2}{r_{p2}}+\frac{k_eq_{3}}{r_{p3}}\)
\(\Longrightarrow V_{tot}=\frac{(8.99 \times 10^9 \ \frac{Nm^2}{C^2})(2 \times 10^{-6} \ C)}{0.12 \ m}+\frac{(8.99 \times 10^9 \ \frac{Nm^2}{C^2})(-2 \times 10^{-6} \ C)}{0.05 \ m}\)
\(\Longrightarrow V_{tot}=149833 \ V-359600 \ V\)

The International Space Station (ISS) orbits the Earth every 90 minutes. The Earth has an average radius of 6371 km and an approximate mass of m = 5.97 × 1024 kg. The gravitational force between two massive objects is calculated using the following formula: =∙m1m2,where=6.674×10−11m3⁄kg∙s2 If we assume the Earth to be spherical and the ISS orbit perfectly circular: a) Calculate the angular velocity of the ISS. (1) b) Calculate the height above the Earth’s surface at which the ISS orbits. (5) c) Calculate the tangential (linear) speed the ISS must travel to maintain this orbit. 2 Give your answer in km/h, rounded to the nearest whole number.
Answers
The angular velocity of the ISS is 0.012 rad/s. the height above the Earth's surface at which the ISS orbits is 408 km. the tangential speed of the ISS is 7 km/s.
a) Calculate the angular velocity of the ISS.
The angular velocity of the ISS can be calculated using the following formula:
ω = v / r
where:
ω is the angular velocity in radians per second
v is the tangential velocity in meters per second
r is the radius of the orbit in meters
The tangential velocity of the ISS is the speed at which it travels along the circumference of its orbit. The radius of the ISS's orbit is the distance from the center of the Earth to the ISS.
In this case, the tangential velocity of the ISS is 7.66 kilometers per second. The radius of the ISS's orbit is 6371 kilometers. Therefore, the angular velocity of the ISS is:
ω = 7.66 km/s / 6371 km = 0.012 rad/s
b) Calculate the height above the Earth’s surface at which the ISS orbits.
The height above the Earth's surface at which the ISS orbits can be calculated using the following formula:
h = r * (1 - (1 - e^2)^(1/2))
where:
h is the height above the Earth's surface in meters
r is the radius of the Earth in meters
e is the eccentricity of the orbit
The eccentricity of the ISS's orbit is 0.016. Therefore, the height above the Earth's surface at which the ISS orbits is:
h = 6371 km * (1 - (1 - 0.016^2)^(1/2)) = 408 km
c) Calculate the tangential (linear) speed the ISS must travel to maintain this orbit.
The tangential speed of the ISS can be calculated using the following formula:
v = ω * r
where:
v is the tangential speed in meters per second
ω is the angular velocity in radians per second
r is the radius of the orbit in meters
The angular velocity of the ISS is 0.012 rad/s. The radius of the ISS's orbit is 6371 kilometers. Therefore, the tangential speed of the ISS is:
v = 0.012 rad/s * 6371 km = 7.66 km/s

what is the relation between the current through the resistor and the voltage drop across the resistor
Answers
By way of Ohm's Law, the voltage drop is proportional to the cutting-edge flowing thru a resistor. (So in numerous collection resistors with the same resistance, the drop across each one is identical, because the present day throughout each one is equal).
The connection between the current, voltage, and resistance is expressed through Ohm's regulation. This states that the modern-day flowing in a circuit is at once proportional to the implemented voltage and inversely proportional to the resistance of the circuit, provided the temperature stays steady.
Resistors in the collection deliver identical cutting-edge, however, the voltage drop throughout them isn't the same as their man or woman resistance values will create one-of-a-kind voltage drops across every resistor as decided by way of Ohm's regulation ( V = I*R ).

Given a block of wood with a height of 10.0 cm. When placed in water, 9.00 cm of this block's height are above water. What is the density of this block in units of grams/cm^3? A)1 B)10 C)0.9 D)0.1 E)9
Answers
We are given a wooden block that floats in water. The given problem can be exemplified in the following diagram:
To determine the density of the block we need to use the fact that, according to Archimedes principle, the weight of the displaced liquid is equal to the weight of the object, therefore, we have:
\(w_{\text{water}}=w_{\text{block}}\)Where:
\(\begin{gathered} w_{\text{water}}=\text{ weight of water} \\ w_{\text{block}}=\text{ weight of the block} \end{gathered}\)The weight is the product of the mass and the acceleration of gravity, therefore, we have:
\(m_{\text{water}}g=m_{\text{block}}g\)\(\begin{gathered} m=\text{ mass} \\ g=\text{ acceleration of gravity} \end{gathered}\)Now, the mass is the product of the density and the volume, therefore, we have:
\(\rho_{water}m_{water}g=\rho_{block}m_{block}g\)\(\rho=\text{ density}\)We can cancel out the acceleration of gravity and we get:
\(\rho_{water}V_{water}=\rho_{block}V_{block}\)Now, the volume of the water is equivalent to the height that is underwater multiplied by the width and the length of the block:
\(\rho_{water}(1cm)(w)(l)=\rho_{block}V_{block}\)Where:
\(\begin{gathered} w=\text{ width} \\ l=\text{ length} \end{gathered}\)Also, the volume of the block is the height of the block multiplied by the width and the height:
\(\rho_{water}(1cm)(w)(l)=\rho_{block}(10cm)(w)(l)\)Now, we cancel out the width and the length
\(\rho_{water}(1cm)=\rho_{block}(10cm)\)Now, we solve for the density of the block by dividing both sides by 10:
\(\frac{\rho_{water}(1cm)}{10cm}=\rho_{block}\)The density of water in g/cm^3 is given by:
\(\rho_{water}=1\frac{g}{cm^3}\)Substituting we get:
\(\frac{(1\frac{g}{cm^3})(1cm)}{10cm}=\rho_{block}\)Solving we get:
\(\frac{1}{10}\frac{g}{cm^3}=\rho_{block}\)In decimal form this is:
\(0.1\frac{g}{cm^3}=\rho_{block}\)Therefore, the density of the block is 0.1 g/cm^3

Answers
The number of grains of sand in the Sahara Desert are 1.128 × 10²⁵.
To calculate the approximate number of grains of sand in the Sahara Desert, we need to determine the volume of the desert and then multiply it by the number of grains per cubic centimeter.
1. Calculate the volume of the Sahara Desert:
Area = 9,400,400 km²
Average depth = 150 m = 0.15 km
Volume = Area × Average depth
= 9,400,400 km² × 0.15 km
= 1,410,060 km³
2. Convert the volume to cubic centimeters (cm³):
1 km³ = 1,000,000,000,000 cm³ (conversion factor)
Volume (cm³) = Volume (km³) × 1,000,000,000,000
= 1,410,060 km³ × 1,000,000,000,000
= 1.41 × 10²¹ cm³
3. Calculate the approximate number of grains of sand:
1 cm³ = 8,000 grains (given)
Number of grains of sand = Volume (cm³) × 8,000
= 1.41 × 10²¹ cm³ × 8,000
= 1.128 × 10²⁵ grains

________ refers to fat storage in the waist, hips, and thighs.
Answers
The term pear-shaped refers to fat storage in the waist, hips, and thighs.
The concept of body fat distribution refers to how fat is stored in different areas of the body. The two primary patterns of fat distribution are commonly referred to as "apple-shaped" and "pear-shaped." The term "pear-shaped" specifically describes the fat storage pattern where individuals tend to accumulate excess fat in the waist, hips, and thighs.
In the pear-shaped pattern, fat is deposited predominantly in the lower body, giving the body a narrower upper torso (waist) compared to the wider lower body (hips and thighs), resembling the shape of a pear. This distribution is more common in individuals with a lower body mass index (BMI) and is often associated with the female body shape.
Several factors contribute to the pear-shaped fat distribution, including genetics, hormones, and age. Hormones such as estrogen play a role in directing fat storage in specific areas, and genetic predispositions can influence where fat is deposited. Additionally, as individuals age, hormonal changes and shifts in body composition can impact fat distribution patterns.
Understanding body fat distribution patterns can have implications for overall health. While excess fat storage in the lower body (pear-shaped) is generally considered less risky than excess fat storage in the abdominal region (apple-shaped), both patterns can still contribute to health risks and complications.
It is important to maintain a balanced and healthy lifestyle, including regular physical activity and a nutritious diet, to manage body fat distribution and promote overall well-being.

The distance between two fringes can be calculated by β=λDd where β represents fringe width, λ represents wavelength, D represents the distance between slit and screen, and represents the distance between two slits. The fringe width depends on the wavelength of light, the distance between the slits, and slit separation.
The bright (constructive interference) fringes are at maximum intensity and the dark (destructive interference) fringes are at minimum intensity. Fringe is the alternating light and dark band that forms due to interference. Fringe width is the distance between two successive bright or dark fringes.

Answers
Answer:
210 m/s
Explanation:
We will use this equation for an elastic collision:
m₁v₁ + m₂v₂ = m₁v₁ + m₂v₂ The left side of the equation is before the collision; the right side is after the collision.In this case, m₁ = mass of golf ball (0.046 kg) and m₂ = mass of the golf club (0.22 kg).
Left side of equation:v₁ is 0 m/s since the ball is at rest on the tee.
v₂ is 44 m/s, given in the problem.
Right side of equation:v₁ is what we are trying to find.
v₂ is 0 m/s since the ball will be at rest on the ground.
⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯Plug these values into the elastic collision equation:
(0.046 kg)(0 m/s) + (0.22 kg)(44 m/s) = (0.046 kg)(v₁) + (0.22 kg)(0 m/s)Simplify this equation.
(0.22 kg)(44 m/s) = (0.046 kg)(v₁)Get rid of the units.
(0.22)(44) = 0.046v₁Multiply the left side of the equation.
9.68 = 0.046v₁Divide both sides by 0.046.
210.434782609 = v₁ 210 m/s = v₁The speed of the ball when it leaves the tee is about 210 m/s.
how does the electric potential energy between two positively charged particles if the distance is increase by a factor of 2
Answers
Answer: Potential energy is decreased by a factor of 2.
Explanation:
Potential energy can be defined as the capacity for doing work that arises from position or configuration.
In the electrical case, a charge will exert a force on any other charge and potential energy arises from any collection of charges.
The magnitude of electric potential relies on the amount of work done in moving the object from one point to another against the electric field.
Potential energy between two positive charges is given by
U =(kq1q2)/r
Therefore, U is inversely proportional to the distance between the charges(r).
If r becomes half, then U gets doubled.
Therefore, the potential energy decreases by a factor of 2.
