Amplitude does not mean a note has a high pitch
Answer:
Acceleration at its most basic is the act of increasing your running speed. From a standing start (or blocks), you explode into action. If you’re already running, you pick up the pace. Acceleration continues until you can no longer increase your speed, at which point you achieve maximum velocity (top-end speed). Acceleration seems simple enough. The plus means your increasing speed, the k=minus means your decreasing in speed.

Answer:
The values of gravitational force and gravitational constant become same or equal when product of masses involved equals the square of distance between them.
Answer:
Speed = 450 miles per hour
Explanation:
Given the following data;
Time = 2 hours
Distance = 900 miles
To find the speed of the plane;
Speed can be defined as distance covered per unit time. Speed is a scalar quantity and as such it has magnitude but no direction.
Mathematically, speed is given by the equation;
![Speed = \frac{distance}{time}](https://tex.z-dn.net/?f=Speed%20%3D%20%5Cfrac%7Bdistance%7D%7Btime%7D)
Substituting into the formula, we have;
![Speed, S = \frac{900}{2}](https://tex.z-dn.net/?f=Speed%2C%20S%20%3D%20%5Cfrac%7B900%7D%7B2%7D)
Speed = 450 miles per hour
Answer:
The weight will be smaller than on Earth.
Explanation:
We call weight, to the product of the mass times the acceleration produced on this mass, due to the Universal law of gravitation.
This acceleration can be obtained applying Newton’s 2nd Law to the gravitational attractive force, as follows:
Fg = G m1m2 / (r12)2 = m1* a → a= G m2 / (r12)2 =g
If we take a planet with the same mass, but a larger size, this means that the distance, from the planet’s surface to the center, will be larger also.
As the gravitational attraction is inversely proportional to the square of the distance, this means that the acceleration caused by this force, will be smaller than on Earth.
As the mass is an universal constant, this means that the weight (as measured on a scale as the normal force) will be smaller also.
