What kind of waves are present during an earthquake? ...

Physics
1 answer:
Brrunno [24]3 years ago
6 0

Answer:

1. The two main types of waves are body waves and surface waves. Body waves can travel through the earth's inner layers, but surface waves can only move along the surface of the planet like ripples on water. Earthquakes radiate seismic energy as both body and surface waves.

2. potential energy

3. Newton's second law of motion is F = ma, or force is equal to mass times acceleration.

4. Refraction is the bending of light

5. Density uses the formula p=m/V, or density (p) is equal to mass (m) divided by volume (V). Density is defined as mass per unit volume.

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
