the following equation is an example of alpha decay
The thrust force that cause the small rocket can be defined as a push, Thrust is a force or a push.
From Newton's First Law
Newton's first law can be stated as:
A body will continue ti be arrest or uniform motion except acted upon by an external force
If an object, such as the rocket, is at rest then the forces on it are balanced. It takes an additional force to unbalance the forces and make the object move. If the object is already moving, it takes such an unbalanced force, to stop it, change its direction from a straight line path, or alter its speed.
Newton's Second Law
This law of motion is essentially a statement of a mathematical equation. The three parts of the equation are
Using letters to symbolise each part, the equation can be written as follows:
<em>F = ma</em>

mass = 30kg
frictional force = coefficient of friction * (mass * g)
g = 9.8 m/s^2
So:
60N = x * 294 N
x = 60 N / 294 N = 0,2
To solve this problem we will apply the concepts related to the wavelength of its third harmonic.
It describes that the wavelength is equivalent to
Here,
The wavelength is in turn described as a function that depends on the change of the speed as a function of the frequency, that is to say
In this case the speed is equivalent to the speed of sound and the frequency was previously given, therefore
Finally the length of the pipe would be
Answer:
Explanation:
An object will remain at rest or in uniform in a straight line upon an external force
