what is the electric potential 4.20 m from a -3.37*10^-6 C charge?
Answer:
[tex]V =-7221.43 \ V[/tex]
Explanation:
The Electric Potential
The electric potential at a point is equal to the electric potential energy (measured in joules) of any charged particle at that location divided by the charge (measured in coulombs) of the particle.
To calculate the electric potential of a point charge Q at a distance r, we use the formula:
[tex]\displaystyle V=\frac{kQ}{r}[/tex]
Where
[tex]k=9\cdot 10^9\ N.m^2/c^2[/tex]
We are given the following data:
[tex]Q=-3.37\cdot 10^{-6}\ c[/tex]
r = 4.20 m
Calculating:
[tex]\displaystyle V=\frac{9\cdot 10^9*(-3.37\cdot 10^{-6})}{4.2}[/tex]
[tex]\mathbf{V =-7221.43 \ V}[/tex]

PLZZZZ HELP QUICK . 30 points. Emma weighs 560 N, she has decided to stay in shape so she is working out every morning, This morning she ran and lifted weight! 1. Calculate Emma's mass ( Gravity g= 9.8 N/kg). 2. If she ran 350 meters in 65 seconds, what was her velocity? 3. When she lifted weights, she exerted a 35 N to lift one of the weight 2 meters over the ground, what is the amount of work she performed? Note that units are important, so do not give any number without a unit to avoid losing points.
Force equals mass time acceleration. Weight is a force and it can replace force in the equation. The acceleration would be gravity, which is an acceleration.
1.)
Fw (weight) = m (mass) · g (gravity, 9.8 m/s²)
Fw = m * 9.81 m/s²
560N = m · 9.81 m/s²
m ≈ 57.08 kg
2.)
d = 350 meters
t = 65 seconds
velocity = d/t
velocity = 350 meters / 65 seconds
velocity ≈ 5.38 meters/sec
3.)
Force = 35N
Distance = 2 meters
Work = Force · Distance
Work = 35N · 2 meters
Work = 70 J

in this setup how can potential energy be converted into kinetic energy .
Answer:
If force is applied to cause the motion of the body
Explanation:
In the setup given in this diagram, potential energy can be converted into kinetic energy by applying force on the cart or object to move it down the slope.
Potential energy is the energy due to the position of a body. The body has huge potential energy at its current position.
Kinetic energy is the energy due to the motion of a body.
As the body moves down the slope and its velocity increases, it gains massive kinetic energy.
Down the slope, the kinetic energy increases as the potential energy decreases.
At the bottom of the slope, the potential energy becomes zero and the kinetic energy is at its maximum.
1. Explain how you calculate the net force in any direction on the box.
2. Suppose an upward force of 15 N is added to the box. What will be the net vertical force on the box?
3. What force could be applied to the box to make the net force in the horizontal direction zero? Explain.
4. Suppose a force of 25 N to the right is added to the box. What will be the net force to the right?
1.Explain how you calculate the net force in any direction on the box.
If the two horizantal (left to right) forces act on an object in opposite directions and they don't exactly cancel out, what is left over is the net force In the diagram, the net force is 50 Newtons.
The equation you have to do (100 N - 50 N = 50 N).
If the two vertical (up and down) forces act on an object in opposite directions and they do cancel out, what is left over is the net force In the diagram, the net force is 0 Newtons. The equation you have to do. (25 N - 25 N = 0 N)
Final Answer: 50 N
2.Suppose an upward force of 15 N is added to the box. What will be the net vertical force on the box?
The net vertical force ( up and down) would be 15 N
3.What force could be applied to the box to make the net force in the horizontal direction zero? Explain.
You could apply another horizontal (left to right) force of 50 N then the horizontal net force would be 0 N
4.Suppose a force of 25 N to the right is added to the box. What will be the net force to the right?
If suppose I say I added a horizontal (left to right) net force of 25 right next to the 50 N. The net force for the whole box would be 25 N.
1. The net force in any direction is calculated by calculating the net horizontal force and the net vertical force on the box.
What is Newton's second law?Newton's Second Law states that The resultant force acting on an object is proportional to the rate of change of momentum.
The mathematical expression for Newton's second law is as follows
F = ma
2. If an upward force of 15 N is added to the box, then the net vertical force on the box would be 15 N in the upward direction because earlier the net vertical force on the box was 0 N.
3. A force of 50 N to the right could be applied to the box to make the net force in the horizontal direction zero.
4. If a force of 25 N to the right is added to the box then the net force o the right would be 75 N.

Answer:
m = 2500 [kg]
Explanation:
Newton's Second Law tells us that the sum of forces on a body is equal to the product of mass by acceleration.
∑F = m*a
where:
∑F = sum of the forces = 5.5 [kN] = 5500 [N]
a = acceleration = 2.2 [m/s²]
m = mass [kg]
Now clearing the mass [kg]
[tex]F=m*a\\m=F/a\\m = 5500/2.2\\m=2500 [kg][/tex]

A student lifts a 1.4-kg box of magazines vertically from rest with an upward force of 52.7 N. The distance of the lift is 1.6 meters. Find the
total work done on the box
-64.41
Answer:
The work done on the box is 21.952 Joules
Explanation:
The given parameters are;
The mass of the box of magazines, m = 1.4 kg
The upward force with which the student lifts the magazine = 52.7 N
The distance (height) of the lift, h = 1.6 meters
The work done on the box = The potential energy gained by the box of magazine, P. E.
Potential energy gained by elevation, P. E. = Mass, m × The acceleration due to gravity, g × Height, h
Where;
The acceleration due to gravity, g = 9.8 m/s²
∴ P. E. = m × g × h = 1.4 kg × 9.8 m/s^2 × 1.6 m = 21.952 Joules
The work done on the box = The potential energy gained by the box of magazine, P. E. = 21.952 Joules
The total work done on the box is 21.952 Joules
The workdone on the box is equal to the potential energy possessed by the body. Mathematically;
[tex]W=P.E=mgh[/tex]
m is the mass of the bodyg is the acceleration due to gravityh is the heightGiven the following parameters
m = 1.4kg
g = 9.8m/s²
h = 1.6m
Substitute the given parameters into the formula:
[tex]W = 1.4 \times 9.8 \timees 1.6\\W=21.952Joules[/tex]

The ocean’s tides are not only affected by the shape of the coastlines, or slope of the ocean floor, but also by the gravitational tug of the Sun and the Moon. Write a 600 word report on the effect of the Moon, and Sun, on tidal reaction, and high tides and low tides. What orientation are the Sun and Moon in to create high tides? Low tides? There are two special types of tides. What are they called and what positions are the Sun and the Moon in during these times?
Answer:
a) According to Newton's law of gravitation, as the distance between the Moon and the Earth decreases, the gravitational attraction increases and vice versa
The gravitational force of the Moon on the Earth causes the Earth to be slightly bulged on the side directly facing the Moon
The gravitational force also pulls the water bodies on the Earth's surface towards the Moon in the same manner and the effect is more pronounced due to the ability of the liquid water to assume a shape based on the magnitude of the gravitational field attracting it
Therefore, the region where the Moon is closest to the Earth we have a high tide as the water level rises and the region which is perpendicular to where the Moon is located has a low tide
b) The two special types of tides are
1) The neap tide
2) The spring tide
Neap tide
Neap tide occurs when the Sun and Moon are 90° apart from each other when they are viewed by an observer from Earth
The gravitational pull of the Sun cancels (partially) the effect of the gravitational pull and tidal force of the Moon, resulting in minimum tidal range
Spring Tide
Spring tide occurs when the Earth, the Moon, and the Sun are simultaneously inline, such that the Sun reinforces the gravitational pull and tidal force of the Moon, resulting in a maximum tidal range
