How do balanced forces affect motion?

How would an unbalanced chemical equation convey misleading information about what took place during a chemical reaction?

In a stringed musical instrument, the part that vibrates in resonance with the sound waves produced by the strings is called the a. reed. b. membrane. c. sounding board. d. diatonic scale.

The electric field of a sinusoidal electromagnetic wave obeys the equation E=? (375V/m) sin[ (5.97*1015rad/s) t + (1.99*107rad/m) x]. Part B:What is the amplitude of the magnetic field of this wave? Part CWhat is the frequency of the wave? B = ? T

In an electric toaster, electricity passes through thin metal wires (called filaments) inside the toaster, causing the wires to glow and heat up. The heat given off by the filaments then toasts the bread.

Why does gravity affect momentum?

A roller coaster has a mass of 500 kg. It drops from rest at the top of a hill that's 57 m tall. How fast is it going when it reaches the bottom? Acceleration due to gravity is g = 9.8 m/s2.

Two sinusoidal waves are moving through a medium in the positive x-direction, both having amplitudes of 7.00 cm, a wave number of k=3.00m-1, an angular frequency of ω=2.50s-1, and a period of 6.00 s, but one has a phase shift of an angle ϕ=π12rad.

For a vacation, you and your family fly east to west from Boston, Massachusetts, to Seattle, Washington. You notice that your flight back home to Boston is shorter than your flight to Seattle. Which phenomenon causes your flight home to be shorter?

You spy on an anchor on the bottom of a lake. What is the direction and amount of force the water exerts on it: a) zero b) up, equal to the weight of the anchor. c) up, less than the weight of the anchor d) down, equal to the weight of the anchor.

How are electromagnetic waves different from matter waves?
