Constellations are based off of many Greek and Roman fables. Many of their gods and beliefs are pictured in the stars, which is where we get most of our constellations. Hope this helps!
Answer:
v = rw
Explanation:
When an object is rolling continuously without slipping, then every angle it rotates through, is equal to a distance the perimeter has rotated.
If the object completes 10 revolutions and takes a particular time, let's say t to complete it. The angular distance would then be 20 π rad, while its angular velocity will be 20 π/t
The circumference will somehow translate to the distance it covers, which is 20πr, this means that the speed is 20πr/t
So, like the question asked, the linear speed compared to angular speed is
v : w
20πr/t : 20πt, which can be simplified to
r : 1
In essence, v = rw
Answer:
Explanation:
In this process energy must be conserved. On the initial stage, there will be only gravitational potential energy, while on the final stage there will be only elastic potential energy, so they will be equal. We write this as:
Which is the same as:
So we can obtain our mass from there, and for our values:
Answer:
2.31J
Explanation:
the energy for a spring system is given by:
where 
is the spring constant: 
and 
is the distance stretched from the equilibrium position.
In the first case 
so the energy to stretch the spring 1.81cm is:
and for the second case, the energy to stretch the spring 5.79cm:
so to answer a) we must find the difference between these energies:
Answer:
