a) Young's modulus of this wire is \(80,907,029 N/m^2\) b) The speed of propagation of sound on the wire is 96.4 m/s. c) The calculated speed of sound is a longitudinal speed.
(a) To calculate Young's modulus of the wire, we can use the formula: Young's modulus (Y) = (Stress) / (Strain)
Stress = Force / Area
Strain = Change in Length / Original Length
Given:
Length (L) = 5.50 m
Cross-sectional area (A) =\(0.100 cm^2 = 0.0000100 m^2 (converted to m^2)\)
Change in length (∆L) = 6.80 mm = 0.00680 m (converted to m)
Force (F) = 1.00 kN = 1000 N (converted to N)
First, let's calculate stress and strain:
Stress = F / A = \(1000 N / 0.0000100 m^2 = 100,000,000 N/m^2\)
Strain = ∆L / L = 0.00680 m / 5.50 m = 0.001236
Now, we can calculate Young's modulus:
Y = Stress / Strain = \(100,000,000 N/m^2 / 0.001236 = 80,907,029 N/m^2\)
(b) To calculate the speed of propagation of sound on the wire, we can use the formula:
Speed of sound (v) = \(sqrt(Y / ρ)\)
Given:
Mass density (ρ) =\(8700 kg/m^3\)
Young's modulus (Y) =\(80,907,029 N/m^2\)
Now, we can calculate the speed of sound:
\(v = sqrt(80,907,029 N/m^2 / 8700 kg/m^3) = sqrt(9297.6 m^2/s^2) = 96.4 m/s\)
(c) The calculated speed of sound is a longitudinal speed. This is because the speed of sound in a solid medium, such as a wire, is related to the compressions and rarefactions of the material along the direction of propagation, which characterizes a longitudinal wave.

The baker needs 9 eggs, 6 cups of flour, 3 cups of sugar, and 3 sticks of butter to make a total of 3 cakes.. The baker only has 2 sticks of butter. That means the butter is the ___________ because the baker can only make 2 cakes!
Question 19 options:
Product
Reactant
Limiting reactant
Spontaneous reactant
Answer: Limiting reactant
Explanation:
The limiting reactant is a reactant will get completely consumed up in the reaction. This reactant being in low concentration will lead to the formation of limited amount of product.
In the given situation, since the butter cakes are required to be 3 sticks for making 3 cakes but only 2 cakes are available thus the butter stick is the limiting reactant.
thermal noise is unavoidable and can literally be found everywhere in the universe because it is due to _______ motion of ________ in electrical circuits?
Thermal noise is the unavoidable noise that occurs due to the thermal motion of particles in electrical circuits.
This type of noise is present everywhere in the universe as it is due to the thermal motion of particles.
This thermal motion is the random movement of particles that is a result of their temperature. At higher temperatures, the particles in a substance have a higher thermal motion, which results in more thermal noise.
The electrical circuit has resistance, and when a current flows through it, the resistance causes collisions between electrons and other atoms. This interaction between the moving electrons and atoms in the conductor produces thermal noise.
Thermal noise is proportional to the temperature of the conductor and is independent of the current or voltage of the signal passing through it. The power of thermal noise is given by the formula P = kTB, where k is Boltzmann's constant, T is the temperature in Kelvin, and B is the bandwidth of the signal.
Hence, it can be deduced that thermal noise is an inevitable occurrence present universally, as it arises from the thermal agitation of particles within electrical circuits. This phenomenon pervades various environments and cannot be eliminated.

a 55 kg girl swings on a swing, whose seat is attached to the pivot by 2.5 m long rigid rods (considered to be massless in this problem). as she swings, she rises to a maximum height such that the angle of the rods with respect to the vertical is 32 degrees. what is the maximum torque on the rods due to her weight, as she moves during one cycle of her swinging from the bottom of her swing path to the highest point?
To calculate the maximum torque on the rods due to the girl's weight, we can use the equation:
Torque = Force x Distance
First, we need to determine the force acting on the rods due to the girl's weight. The force can be calculated using the formula:
Force = mass x acceleration due to gravity
Given that the girl's mass is 55 kg and the acceleration due to gravity is approximately 9.8 m/s^2, we have:
Force = 55 kg x 9.8 m/s^2 = 539 N
Next, we need to determine the distance from the pivot point to the point where the force is applied. In this case, it is the length of the rigid rods, which is 2.5 m.
Now we can calculate the maximum torque:
Torque = Force x Distance = 539 N x 2.5 m = 1347.5 N·m
Therefore, the maximum torque on the rods due to the girl's weight during one cycle of her swinging is 1347.5 N·m.

On a day with complete cloud cover, what happens to the visible light headed toward Earth?
(a) The clouds reflect much of it back to space, though some still reaches the surface.
(b) It is absorbed by the clouds, which causes the clouds to heat up.
(c) It reaches the surface just as it does on a cloudless day.
On a day with complete cloud cover, the visible light headed toward Earth: The clouds reflect much of it back to space, though some still reaches the surface.
When the sun shines, the Earth's atmosphere scatters it in all directions. This is why certain sections of the Earth appear brighter than others during the day—the Sun's light has been reflected off of the ground and other objects. When the planet is completely clouded over, no light reaches Earth at all. The term "nowhere" refers to the fact that there is no such thing as a sunrise since there is no such thing as a dawn. On a cloudy day, visible light directed toward the earth is misdirected and darkened by the clouds. This is due to the fact that shorter wavelengths of visible light scatter more than longer wavelengths. Rayleigh scattering is the name given to this phenomena.

3. A fire hose is turned on, it exerts a pressure of 10kPa. If the diameter of the
jet is 0.6m, what is the force exerted? (remember there are 1000Pa to a kPa,
and the area of a circle is found by multiplying Pi by the radius squared).
The force exerted by the fire hose is 2.827 kN
force excerted calculation.
First, we need to calculate the area of the jet using the formula for the area of a circle:
Area = π x (radius)^2
We know the diameter of the jet is 0.6m, so the radius is half of that
radius = 0.6m / 2 = 0.3m
Plugging this value into the formula, we get:
Area = π x (0.3m)^2 = 0.2827 m^2
Next, we can use the formula for pressure to calculate the force exerted:
Pressure = Force / Area
Rearranging this formula to solve for force, we get:
Force = Pressure x Area
Plugging in the given values, we get:
Force = 10 kPa x 0.2827 m^2 = 2.827 kN
Therefore, the force exerted by the fire hose is 2.827 kN (kilonewtons).

Five identical light bulbs are going to be connected to a constantvoltage source. Will the bulbs provide more brightness if they areconnected in series, or in parallel?
SELECT ONLY ONE OF THE FOLLOWING:
A)Series.
B)The brightness is the same.
C) Parallel.
Answer:
C) Parallel
When five identical light bulbs are connected to a constant voltage source, they will provide more brightness if they are connected in parallel.
This is because in parallel circuit configuration, each bulb receives the full voltage of the source, resulting in brighter light bulbs.
In contrast, in a series circuit configuration, the voltage is divided equally among the bulbs, resulting in dimmer light bulbs.
An electric circuit is an arrangement of components that are connected by wires and other conductive materials to transmit electric power from a power source to the destination.
The three types of electric circuit connections are series, parallel, and a combination of series and parallel.
The type of connection will determine the amount of current flowing through each component and hence the amount of power each component will dissipate.
In a parallel circuit, the current passing through each component is equal to the total current, while in a series circuit, the current is the same through each component of the circuit.

In our experiment while verifying Snell's law, we used the fact that the incident ray, normal to the refracting surface line, and the refracted ray are in the same plane.
This means that they all lie in a two-dimensional plane and can be described using two-dimensional geometry. It is important to note that they are not in mutually perpendicular planes, as this would mean they are perpendicular to each other and do not lie in the same plane. Additionally, they do not always have the same direction, as the direction of the refracted ray depends on the angle of incidence and the refractive indices of the two media. However, the incident ray and the normal line are always mutually perpendicular, which is a key aspect of Snell's law.
