For any simple harmonic motion, the position, velocity, and acceleration can all be written as the same type of trigonometric function (sine or cosine) by correctly adding a relative phase factor. an x component of the position function given by x(t)=βcos(ωt+δ) is a valid general solution for simple harmonic motion. part a write the x component of the velocity associated with this position function. express your answer in terms of some or all of the variables β, ω, δ and t.

Three coins are flipped. what is the probability that there will be at least two tails?

The blue whale is the largest animal living on the earth. the average blue whale measures 100 feet long (30 meters) and weighs 300,000 pounds (136,000 kilograms). a whale’s head is 1⁄3 of the length of its body. a new baby whale is 1⁄4 the length of a grown whale. the average man is 1⁄17 the length of a blue whale, and 1⁄1,818 its weight. a human baby measures 1⁄4 of the length of an adult. calculate the following information: how long is a whale’s head? how long is a new baby whale? how tall is the average man? how much does the average man weigh? how tall is the average human baby?
