what is the z -component of the electric field at a depth δ beneath the origin along the negative z -axis? express your answer in terms of some or all of the variables σ , r , δ , and the electric constant ϵ0 .
In this problem we have spherical symmetry, so we can apply Gauss theorem to find the magnitude of the electric field:
∫ E(r) . dr = q / ε₀
where the term on the left is the flux of the electric field through the gaussian surface, and q is the charge contained in the surface.
Here we are analyzing the field at a distance , so outside the solid ball. If we take a gaussian sphere with radius r, we can rewrite the equation above as:
E(r) . 4πr² = q/ε₀ (1)
where 4πr² is the surface of the sphere.
The charge contained in the sphere, q, is equal to the charge density times the volume of the solid ball, 4/3πr³ₐ:
q = ρ (4/3πr³ₐ) (2)
Combining (1) and (2), we find
E(r) . 4πr² = (4/3ρπr³ₐ) / (3ε₀)
E(r) = ρπr³ₐ / 3ε₀r²
And we see that the electric field strength is inversely proportional to the square of the distance, r.
B) Now we are inside the solid ball: . By taking a gaussian sphere with radius r, the Gauss theorem becomes
E(r) . 4πr² = q / ε₀ (1)
But this time, the charge q is only the charge inside the gaussian sphere of radius r, so
q = ρ(4/3πr³) (2)
Combining (1) and (2), we find
E(r) . 4πr² = 4ρπr³ / 3ε₀
E(r) = ρr / 3ε₀
And we see that this time the electric field strength is proportional to r.
C) E(0)=0.
limr→∞E(r)=0.
The maximum electric field occurs when r=rb.
From part A) and B), we observed that
- The electric field inside the solid ball (r <r ₐ) isρr / 3ε₀ (1)
so it increases linearly with r
- The electric field outside the solid ball ( r > rₐ) isE(r) = ρrₐ³ / 3ε₀r² (2)
so it decreases quadratically with r
--> This implies that:
1) At r=0, the electric field is 0, because if we substitute r=0 inside eq.(1), we find E(0)=0
2) For r→∞, the electric field tends to zero as well, because according to eq.(2), the electric field strength decreases with the distance r
3) The maximum electric field occur for , i.e. on the surface of the solid ball: in fact, for the electric field increases with distance, while for the field decreases with distance, so the maximum value of the field is for .

what method would astronomers use to find the distance to a galaxy so far away that individual stars are impossible to make out (resolve)?
The method would astronomers use to find the distance to a galaxy so far away that individual stars are impossible to make out (resolve) is finding the redshift .
What is meant by finding redshift ?A manifestation of the Doppler Effect is redshift. The sound or light waves that are released by an object as it moves away from us are stretched out, which lowers their pitch and causes them to migrate towards the red end of the electromagnetic spectrum, where light has a longer wavelength.
An important topic for astronomers is "red shift." The term can be taken literally; when the light's wavelength is stretched, the light is perceived as having "shifted" toward the red portion of the spectrum.

s = u t + 1 / 2 a t²
s = Displacement
u = Initial velocity
t = Time
a = Acceleration
u = 64 ft / s
u = 19.5 m / s
t = 10 s
s = ( 19.5 * 10 ) + ( 1 / 2 * 9.8 * 10² )
s = 195 + 490
s = 685 m
Total distance from the ground,
d = h + s
h = 80 ft = 24.38 m
d = 24.38 + 685
d = 709.38 m
The final position of the object from the ground is 709.38 m

While roller-skating, Granny collides with her tiny grandson Ambrose who is at rest. Ignoring …
a. Granny catches him and they both move together.
b. he and Granny make a bouncing collision, each going in opposite directions.
Momentum is conserved when two moving objects of equal masses collide while traveling in the same direction. The impact between cars 1 and 2 causes car 2 to accelerate.
According to the rule of conservation of momentum, absent an external force, the combined momentum of two or more bodies operating upon one another in an isolated system remains constant. As a result, momentum cannot be gained or lost. Collisions between two objects naturally fall under Newton's third law of motion. When two objects collide, forces of equal magnitude and opposite direction are applied to each object. These forces frequently result in one object gaining momentum and speeding up while the other object slows down.

escribe the following metrology tools: scales, calipers, coordinate measuring machine, and 3-d laser scanner. which is least expensive? which is most accurate?
3D lasers scanner: uses laser projector and cameras to determine part dimensional coordinates to high degree of accuracy, high cost.
Scales: similar to a ruler used for linear measures with "eyeball" accuracy, traditional, affordable, and occasionally insufficiently exact.
Measurements are fairly accurate thanks to the caliper's ability to expand to fit the part being measured.
Coordinate measuring machine: uses probe to touch part and senses x, y, and z coordinate locations that record information into memory (also known as digitizing model), accuracy in the 0.001 mm range, larger volumes greatly increase system cost
No of the size or surface details of the object being scanned, 3D laser scanner uses either phase-based or LIDAR technology to reliably and effectively gather 3-dimensional data. 3D laser scanning generates clear and accurate digital records of present conditions without actually touching what is being measured. The scan generates countless numbers of measurement points known as "coordinates." "Point clouds" are collections of points that together represent raw data. An x, y, and z value is contained in each coordinate in a point cloud. These values are often referred to as northing (y), easting (x), and elevation (z). These points have such fine precision that it is possible to measure exactly from one point to any other point in the point cloud.

Calculate the total mass of the protons and electrons in 19 9f. Use 1. 007825 amu as the mass of 11h (mass of a proton and an electron).
We can conclude that total mass of protons and electrons in is 9.07043 u.
What is Atomic mass ?
Atomic mass means the sum of total number of protons and neutrons present in an atom.
When an atom is neutral then number of protons equal the number of electrons.
Mass of a proton equals to 1.007276 u, mass of neutron equals to 1.008664 u.
For example, in a atom there are total 9 protons and number of neutrons is 19 - 9 = 10.
Since, it is a neutral atom so number of electrons will also be 9.
So, total mass will be calculated as follows.
Total mass = 9 (mass of electron + mass of proton)
= 9 (1.007825 u)
= 9.07043 u
