Answer:
0.0000167283525619 N
Explanation:
= Density of silk = 1300 kg/m³
d = Diameter = 0.002 mm
r = Radius = 0.001 mm
l = Length = 16 cm
f = Frequency = 200 Hz
Mass of the string is
Frequency is given by
The tension on the string is 0.0000167283525619 N
That's the Cosmic Microwave Background (CMB). (D)
It doesn't "provide evidence for the ... Theory". The Big Bang theory is the best explanation (so far) for the CMB and a lot of other observations.
Evidence isn't used to prove theories. Theories are attempts to explain evidence.

Answer:
a
The effect of a change in the price of a new pair of headphones on the equilibrium price of replacement tips ( dp/dpN) is
b
The value of Q and p at equilibruim is
and 
5
The consumer surplus is 
The producer surplus is 
Explanation:
From the question we are told that
The inverse market demand is 
The inverse supply function is 
a
The effect of change in the price is mathematically given as
Now differntiating the inverse market demand function with respect to 
We get that
b
We are told that 
$30
Therefore the inverse market demand becomes
At equilibrium
So we have
Where 
is the quantity at equilibrium
Substituting the value of Q into the equation for the inverse market demand function
5
Looking at the equation for 
we see that
For Q = 0
And for Q = 250
Hence the consumer surplus is mathematically evaluated as
Substituting value
And
The producer surplus is mathematically evaluated as
The kinetic energy at the bottom of the swing is also 918 J.
Assume the origin of the coordinate system to be at the lowest point of the pendulum's swing. A pendulum, when raised to the highest point has potential energy since it is raised to a height h above the origin. At the highest point, the pendulum's velocity becomes zero, hence it has no kinetic energy. Its energy at the highest point is wholly potential.
When the pendulum swings down from its highest position, it gains velocity. Hence a part of its potential energy begins to convert itself into kinetic energy. If no dissipative forces such as air resistance exist, then, the law of conservation of energy can be applied to the swing.
Under the action of conservative forces, the total mechanical energy of a system remains constant.This means that the sum of the potential and kinetic energies of a body remains constant.
When the pendulum reaches the lowest point of its swing, it is at the origin of the chosen coordinate system. Its vertical displacement from the origin is zero, hence its potential energy with respect to the origin is zero. Therefore the entire potential energy of 918 J should have been converted into kinetic energy, according to the law of conservation of energy.
Thus, the kinetic energy of the pendulum at the lowest point of its swing is equal to the potential energy it had at its highest point, which is equal to <u>918 J.</u>
Answer: True
Explanation: Metamorphism is the changing of rocks by heat and pressure. During this process, rocks change either physically and/or chemically. They change so much that they become an entirely new rock. Figure 4.22: The platy layers in this large outcrop of metamorphic rock show the effects of pressure on rocks during metamorphism.
