8 revolutions every minute
<h3>
Answer: 130 meters</h3>
===================================================
Explanation:
vi = 5 and vf = 8 are the initial and final velocities respectively. The change in time is t = 20 seconds.
So,
x = 0.5*(vi + vf)*t
x = 0.5*(5+8)*20
x = 130 meters
represents the distance traveled. The first equation shown above is one of the four kinematics equations.
I will give you more than one , hardness,luster,color,streak,cleavage,fracture.
Answer:

Explanation:
From the question we are told that:
Period 
Trial 1
Spring constant 
Period 
Mass 
Trial 2
Period 
Generally the equation for Spring Constant is mathematically given by
\mu=\frac{4 \pi^2 M}{T^2}
Since

Therefore
