How does the kinetic energy of an object relate to its mass and velocity?

Es Which situation is the best analogy for the Doppler effect? A) A large truck is harder to move than a smaller car. A tennis ball strikes a wall and comes back to you. A toy car moves from a carpet to a tile floor and turns.

In levelling, the following staff readings were observed involving an inverted staff, A = 2.915 and B = - 2.028. What is the rise or fall from A to B (only enter numeric answer, no alpha) ?

A box of unknown mass is sliding with an initial speed vi = 4.70 m/s across a horizontal frictionless warehouse floor when it encounters a rough section of flooring d = 4.50 m long.

The other tower WTC2 is 1,362 feet tall, what is it's height in meters?

In a two-body collision, a. momentum is always conserved. b. kinetic energy is always conserved. c. neither momentum nor kinetic energy is conserved. d. both momentum and kinetic energy are always conserved.

The thread around a screw is a lever.

What kind of process can create "rogue" waves? a. Constructive interference c. Refraction b. Destructive interference d. Standing waves

Why can't we see all types of waves in the electromagnetic spectrum?

Two sinusoidal waves travel along the same string. They have the same wavelength and frequency. Their amplitudes are ym1 = 2.5 mm and ym2 = 4.5 mm, and their phases are π / 4 rad and π / 2 rad, respectively.

How are mathematics and science related?
