You find yourself on the number line again. The numbers are still spaced at 1 meter. Starting at zero, you decide to take 75 seconds to walk. You go to +7, +2, +11, -5, 0, -10, and finally -2. What is your distance, displacement, speed, and velocity?

Which subatomic particle has a negative charge

Suppose that f : rn → rm and that a ∈ k, where k is a connected subset of rn . suppose further that for each x ∈ k there exists a δx > 0 such that f(x) = f(y) for all y ∈ bδx (x). prove that f is constant on k; that is, f(x) = f(a) for all x ∈ k

An important dimensionless parameter concerned with very high-speed flow is the mach number, defined as v/c, where v is the speed of the object such as an airplane or projectile, and c is the speed of sound in the fluid surrounding the object. for a projectile traveling at 1170 mph through air at 50 ˚f and standard atmospheric pressure, what is the value of the mach number?
