The amplitude is equivalent to the coefficient of the sine function, so:
Amplitude = 1
The time period of a Sin(x) = 2π
The time period of Sin(4x) = 2π/4 = π/2
The period is π/2
Answer:
A
Contact forces are forces that require the actual contact (touching) of two pieces of matter. ... A field force is a force that works at a distance. No touching is required. Gravity is a good example of a field force, because it works whether or not an object is touching something or touching nothing at all.
Every piece of matter begins “Out of this world”
When the truck accelerates forward the ball will shift to the back of the bed of the truck because of inertia
Here is a very important formula. You should memorize it:
Distance = (speed) x (time) .
Here's how it's used to answer your question:
Distance = (2 m/s) x (600 seconds)
= 1200 meters .
