The equation of a wave along the x-axis is given as: ξ cm = 3.4 sin (1.16 x - 0.85 t) in which ξ is the displacement. Units on the right hand side are 1/cm for К and 1/s for ω. Determine the the traveling speed of the wave. im assuming you get k=1.16 and...

An underwater sonar system uses mid-wavelength sound waves. These waves of 15 cm in wavelength propagate through seawater with an amplitude of 0.038 nm. Seawater has a density of 1030 kg/m3, and sound through seawater travels at a speed of 1530 m/s. What...

Mineral wool is a material used in construction for the purposes of insulation and soundproofing. A sheet of 11 cm in thickness causes the original intensity to decrease to 63% of its original value. You are trying to build a soundproof room that reduces...

The mass of the electron is 9.11 x 10-31 kg and the mass of the proton is 1.67 x 10-27kg. Both carry the same elementary charge (positive for the proton and negative for the electron). If I release both particles from rest at the middle point between two...

An object is on a frictionless inclined plane. The plane is inclined at an angle of 16.9 degrees with the horizontal. Using the accerlation due gravity(9.8m/s squared),what is the magnitude of object's acceleration?

A man stands on the roof of a building that is 50 m tall and throws a rock with a velocity of 35 m/s at an angle of 50 degrees above the horizontal (a) What is the total time in the air (b) What is the horizontal distance from the base of the building to...

Create a Sales application that prompts the user for a series of sales figures and then implements a sorting routine on the sales figures. Output. Enter the number of sales made today: 15 Enter the amount of sales 1:25 Enter the amount of sales 2:65 Enter...

The lengths of pregnancies in a small rural village are Normally distributed with a mean of 268 days and a standard deviation of 12 days. What percentage of pregnancies last beyond 290 days?

Choose a statement from the book giver that best describes one of the main characters. Please make a citation of your text evidence. And explain what this statement suggests about the character

I found a solution to this question in a previous post.

find the energy in one photon using plancks constant, speed of light and wavelength. multiply by a trillion

How can you do this using cosign instead of tangent. I can't seem to get a answer.
