<em><u>Here your answer</u></em>
Fossils are formed in a number of different ways, but most are formed when a plant or animal dies in a watery environment and is buried in mud and silt. Soft tissues quickly decompose leaving the hard bones or shells behind. Over time sediment builds over the top and hardens into rock.

Answer:
a. f₀ = 6.355 Hz ; b. Δf = 6.35 Hz
Explanation:
Given Data:
Length of wire = l =347 m ;
Tension in wire = T = 65.2 * 10⁶N ;
Linear density = μ = 3.35 kg/m ;
Solution:
a)
Fundamental mode = f₀ = (1/2l)*(sqr.root(T/μ))
By putting the values, we get
f₀ = (1/2(347))*
f₀ = 6.355 Hz
b)
To find the frequency difference between successive modes we need to find frequency of second harmonic first
f₁ = (2/2l)*(sqr.root(T/μ))
f₁ = (2/2(347))*
f₁ = 12.71 Hz
Difference is:
Δf = f₁ - f₀ = 12.71 - 6.355
= 6.35 Hz
Answer:
7)
8)
9)
10)
Explanation:
For the problems 7, 8 and 9 we just apply the definition of acceleration, since no more information is given, which is:
So for each problem we will have:
7)
8)
9)
For the problem 10, we use the equation of velocity in accelerated motion:
Since the ball starts from rest and the acceleration is that of gravity (we take the downward direction positive), we have:
As the engine heats up, a natural circulation starts, as coolant rises through the engine block by convection. It passes through the top hose, and into the radiator. Inside the radiator, heat is removed from the coolant as it falls from the top to the bottom.
Hope this helps!
