The 3 electric field strengths are
a) E1 = 4800 N/C, b) E2 = 2400 N/C , c) E3 = 0 N/C
What is Coulomb's Law?
This question can be solved using Coulomb's Law.
Coulomb's Law states that the force of attraction or repulsion between two charged particles is given by the equation F = k*q1*q2/r^2,
where k is the Coulomb Constant (8.99 x 10^9 Nm^2/C^2), q1 and q2 are the charges of the two particles, and r is the distance between them.
First, we need to calculate the electric field strength at each of the given distances (1.0 cm, 2.0 cm, and 3.0 cm).
To do this, we can use the equation E = k*q/r^2,
where k is the Coulomb Constant (8.99 x 10^9 Nm^2/C^2), q is the charge of the rod, and r is the distance between the rod and the point of interest.
For E1, we can calculate the electric field strength at 1.0 cm to the right of the rod on the left as follows:
E1 = 8.99 x 10^9 Nm^2/C^2 * 12 N/C / (0.01 m)^2
= 8.99 x 10^11 N/C
= 8990 x 10^6 N/C
= 4800 N/C
For E2, we can calculate the electric field strength at 2.0 cm to the right of the rod on the left as follows:
E2 = 8.99 x 10^9 Nm^2/C^2 * 12 N/C / (0.02 m)^2
= 4.495 x 10^11 N/C
= 4495 x 10^6 N/C
= 2400 N/C
For E3, we can calculate the electric field strength at 3.0 cm to the right of the rod on the left as follows:
E3 = 8.99 x 10^9 Nm^2/C^2 * 12 N/C / (0.03 m)^2
= 2.997 x 10^11 N/C
= 2997 x 10^6 N/C
= 0 N/C
Therefore, the electric field strengths E1, E2, and E3 at distances 1.0 cm, 2.0 cm, and 3.0 cm to the right of the rod on the left, along the line connecting the midpoints of the two rods are 4800 N/C, 2400 N/C, and 0 N/C, respectively.

1. A steel container expands in volume 1% when the pressure with in it is increased by 70Mpa. At standard pressure, it holds 8kg of water; =1000kg/m3. For K=2.05Gpa, when it is filled, how many kilograms of water must be added to increase the pressure to 70Mpa (gage)?
0.268 kg of water must be added to increase the pressure to 70 Mpa (gage).
Solving for how many kilograms of water must be added to increase the pressure to 70 Mpa (gage):To find the amount of water needed to increase the pressure to 70Mpa, we need to use the formula:
Change in volume = (Initial volume) x (Change in pressure)
Young's modulus
The initial volume of the container is 8 liters, since the container holds 8kg of water at standard pressure and the density of water is 1000 kg/m³.
So, change in volume = 8 x 10⁻³ m³
We know that the container expands by 1% when the pressure inside it is increased by 70 MPa, and we want to find the amount of water needed to increase the pressure to 70 MPa.
So, Change in pressure = 70 MPa
Young's modulus (K) = 2.05 GPa
Therefore, Change in volume = (8 x 10⁻³) x (70 / 2.05 x 10^9) = 2.68 x 10⁻⁵ m³
To find the amount of water needed to increase the pressure to 70 MPa, we need to multiply the change in volume by the density of water.
So, amount of water needed = (2.68 x 10⁻⁵) x (1000) = 0.268 kg
Therefore, 0.268 kg of water must be added to increase the pressure to 70 Mpa (gage).

A bullet in a rifle accelerates uniformly from rest at 65 000 m/s2. If the velocity of the bullet as it leaves the muzzle is 450 m/s, (i) how long is the rifle barrel? (ii) How long did it take for the bullet to travel the length of the barrel? (iii) What is the average speed of the bullet?
The length of the rifle barrel will be about 0.69 cm. It took the bullet about 0.0069 milliseconds to travel the length of the barrel. And the average speed of the bullet is approximately 441.9 m/s.
(i) how long is the rifle barrel?
To find the length of the rifle barrel, we can use the equation:
length = (velocity^2 - initial velocity^2) / (2 * acceleration)
Plugging in the given values:
length = (450 m/s)^2 / (2 * 65 000 m/s^2) = 0.0069 m
So the length of the rifle barrel is about 0.69 cm.
(ii) How long did it take for the bullet to travel the length of the barrel?
To find the time it took for the bullet to travel the length of the barrel, we can use the equation:
time = velocity / acceleration
Plugging in the given values:
time = 450 m/s / 65 000 m/s^2 = 0.000069 s
So it took the bullet about 0.0069 milliseconds to travel the length of the barrel.
(iii) What is the average speed of the bullet?
To find the average speed of the bullet, we use the formula:
average speed = total distance / total time
Given that the bullet is accelerating uniformly, we can use the harmonic mean formula to find the average speed
average speed = 2 * length * velocity / (length + velocity/acceleration)
Plugging in the given values:
average speed = 2 * 0.0069 m * 450 m/s / (0.0069 m + 450 m/s/65000m/s^2) = 441.9 m/s
So the average speed of the bullet is approximately 441.9 m/s.

suppose an uncharged solid steel ball, for example, one of the steel balls used in an old-fashioned pinball machine, is resting on a perfect insulator. some small amount of negative charge (say, a few hundred electrons) is placed at the north pole of the ball. if you could check the distribution of the charge after a few seconds, what would you detect?
After a few seconds, you would detect that the negative charge has spread out over the entire surface of the steel ball. This is because steel is a good conductor of electricity, so the charge quickly distributes itself evenly over the metal surface.
What factors would affect the charge distribution on the surface of the steel ball?The charge distribution on the surface of the steel ball would be affected by several factors. The material properties of the steel ball, such as its electrical conductivity and dielectric constant, would affect how the charge is distributed. The distance between the charged particle and the steel ball, as well as the size of the steel ball, would also be important factors. The presence of any other charged particles or electric fields in the vicinity of the steel ball would also affect the charge distribution.

A furnace wall consists of 125 mm wide refractory brick and 125 mm wide insulating firebrick separated by an air gap. The outside wall is covered with a 12 mm thickness of plaster. The inner surface of the wall is at 11000C and the room temperature is 250C. The heat transfer coefficient from the outside wall surface to the air in the room is 17 W/m2K, and the resistant to heat flow of the air gap is 0. 16K/W. The thermal conductivities of refractory brick, insulating firebrick, and the plaster are 1. 6, 0. 3, and 0. 14 W/mK respectively. Calculate:
(i) the rate of heat loss per unit area of wall surface;
(ii) the temperature at each interface throughout the wall;
(iii) the temperature at the outside surface of the wall.
The temperature at the outside surface of the wall is 1344 0.8 watts.
What is the temperature at the outside surface of the wall?Determine the loss rate per square foot of the wall surface. Our refractor block brick's thermal resistance is equal to B divided by K. A times one. Thus, this is equal to 1.6 times one divided by 12.5 times 10 to the negative three. Our air gap contributes 0.16 K per W to our thermal resistance. We have three fire bricks as a result. Three divided by K gives us B. A thrice. This equals 0.3 times one divided by 1 25 times 10 to the negative three. Because of our plaster, four equals four divided by B divided by K.Four times our area is equal to 12 x 10 3 / 30.14 x 1 or 4 times our area. Furthermore, our thermal resistance is not equal to one divided by H but rather by A due to the heat transfer from the outside. This makes 1/7. The reason why adding R. One plus R. A plus R. three plus our four plus are ineffective is because of our total net thermal resistance. We thus obtain 0.799 K per W. The rate of heat loss throughout our entire surface area, Q, is equal to T. W minus T.

if a furnace is using 1280 lbs./hr of oxygen, what is the correct balance equation and how much pentane will completely combustion?
The balance equation for pentane, C5H12's complete combustion is 5CO2 (g) + 6H2O = C5H12 (l) + 8 O2 (g) (g).
First, we should comprehend how hydrocarbons burn. A hydrocarbon, or molecule made up only of carbon and hydrogen atoms, is pentane, C5H12. When talking about the combustion of hydrocarbons, the two by products that are typically predicted are CO2 and 6H2O. Keeping in mind that "reaction with O2" refers to combustion, we may create the equation shown below: O2 (g) + C5H12 (l) + CO2 (g) + H2O (g), Therefore, we may determine the equation's balance by counting the number of atoms in each side of the equation. 5 C atoms, 12 H atoms, and 2 O atoms are on the right side. Left: one C atom, two H atoms, and three O atoms. By dividing CO2 by 5, we can begin to establish a balance: O2 (g) + C5H12 (l) = 5CO2 (g) + H2O (g).

determine the circulation for the given vector field around the enclosed half circle of radius 1.
To determine the circulation for the given vector field around the enclosed half circle of radius 1, we need to calculate the line integral of the vector field along the boundary of the half circle.
The line integral is calculated by integrating the dot product of the vector field and the differential of the boundary. The circulation is then equal to the line integral divided by 2π. To calculate the line integral, we need to know the vector field and the boundary of the half circle. Once we have this information, we can use the equation for the line integral to calculate the circulation.

to practice problem-solving strategy 15.1 mechanical waves. waves on a string are described by the following general equation y(x,t)
The transverse displacement will be 0.089963 m. The velocity of the shear wave particles is orthogonal to the direction of the wave.
What is transverse displacement?
Here given the data
Then the equation y(x,t)=Acos(kx−ωt)
speed (v) = 9.00 m/s
amplitude (A) = 9.00 × 10^−2 m
wavelength (λ ) = 0.480 m
We have to find out transverse displacement.
Here we know that.
v = angular frequency / wave number
also wave number = 2 / λ
= 2 / 0.480
= 13.0899
angular frequency = v x k
angular frequency = 9.00 × 13.0899
angular frequency = 117.8097 rad/sec
= 118 rad/sec
Therefore, the equation y(x,t)=Acos(kx−ωt)
y(x,t)=9.00 × 10^−2 cos(13.0899 x−118t)
If x =0 and and t = 0
Then, maximum y(x,t)= 9.00 × 10^−2 cos(13.0899 (0) − 118 (0))
= 9.00 × 10^−2 m
if x = 1.59 m and t = 0.150 s
Then,
y(x,t) = 9.00 × 10^−2 cos(13.0899 (1.59) −118(0.150) )
y(x,t) = 9.00 × 10^−2 × (0.99959)
y(x,t) = 0.089963 m
Therefore the transverse displacement is 0.089963 m
