A disk of radius R = 7.52 cm is centered at the origin and lies along the y – z plane. The disk has a surface charge density σ =
mr Goodwill [35]

Answer:

The electric field produced by this disk along the x axis at point (P = 1.01 m, 0.00 m) is 996.54 N/C

Explanation:

The electric field produced by this disk along the x axis at point (P = 1.01 m, 0.00 m), will be evaluated as follows:

Since x > 0

E_{x} = 2\pi \sigma k [1-\frac{x}{\sqrt{x^2 +R^2}}]

σ is surface charge density = 5.88 × 10⁻⁶ C / m²

R is the radius = 7.52cm = 0.0752m

position x = 1.01m

k is coulomb force constant = 8.99 × 10⁹ Nm² / C²

E_{x} = 2\pi ( 5.88X10^{-6})(8.99 X10^9)[1-\frac{1.01}{\sqrt{1.01^2 +0.0752^2}}]

    = 996.54 N/C

Therefore, The electric field produced by this disk along the x axis at point (P = 1.01 m, 0.00 m) is 996.54 N/C

Catalysts are used in the oil industry to increase octane ratings in gasoline. Octane ratings tell how much fuel has to be compressed to promote better fuel ignition in some cars. The catalytic effect that would be most beneficial for the oil industry is that more products can be formed from a given amount of material.

What are the 4 rules of seismic waves?
elena-14-01-66 [18.8K]
"The are many different seismic waves, but all of basically of four types:

Compressional or P (for primary)
or S (for secondary)
Love
Rayleigh
An earthquake radiates P and S waves in all directions and the interaction of the P and S waves with Earth's surface and shallow structure produces surface waves."

What evidence can you cite for the particle nature of light? 1. Refraction phenomenon of light 2. The many colors of light 3. Di
GalinKa [24]
Evidence for the particle nature of light are not: 1. refraction, 2.  many colors of light, 3. diffraction. These are all phenomenon that support wave theory of light. Evidence for particle nature of light is photoelectric effect. Because it was discovered that you need discrete energies of light to eject electrons from a metal surface and not continuous as the wave theory of light suggests.

A 1.2 kg block of wood hangs motionless from strings. A 50 gram bullet, traveling horzontally, strikes the block and becomes emb
Firdavs [7]

Answer:

speed of the bullet before it hit the block is 200 m/s

Explanation:

given data

mass of block m1 = 1.2 kg

mass of bullet m2 = 50 gram = 0.05 kg

combine speed V= 8.0 m/s

to find out

speed of the bullet before it hit the block

solution

we will apply here conservation of momentum that is

m1 × v1 + m2 × v2 = M × V    .............1

here m1 is mass of block and m2 is mass of bullet and v1 is initial speed of block i.e 0 and v2 is initial speed of bullet and M is combine mass of block and bullet and V is combine speed of block and bullet

put all value in equation 1

m1 × v1 + m2 × v2 = M × V

1.2 × 0 + 0.05 × v2 = ( 1.2 + 0.05 ) × 8

solve it we get

v2 = 200 m/s

so speed of the bullet before it hit the block is 200 m/s
