A 70.0Kg cyclist Rides a 15.0kg
mountain Bike with a Speed of
15m/s Calculate the magnitude
of the momentum of the Bike-rider
system Round your answer to the nearest hundred
Answer:
[tex]1275 kg*m/s[/tex]
Explanation:
We'll use the momentum equation:
[tex]p=mv[/tex]
where:
p = momentum
m = mass
v = velocity
Since we're doing the magnitude of momentum of the system, we'll add the mass of the cyclist and the mountain bike together:
[tex]70.0 kg + 15.0kg=85.0 kg[/tex]
Given that, we can now substitute our given values into the momentum equation:
[tex]p=mv\\p=85.0kg*15.0m/s[/tex]
Our final answer is:
[tex]p= 1275 kg*m/s[/tex]
What theory of mercury's origin can best explain the fact that its core is made of such dense materials?
Answer:
Giant impacts in its early history may have torn away much of its original crust and mantle.
So Mercury has a giant iron core, but why?
There are three general ideas.
1. Mercury was once the core of a gas giant that vaporized when the Sun became a fully-fledged star. This gas giant was probably more like Uranus or Neptune than Jupiter or Saturn.
There are significant issues here, especially that Mercury's existing surface has been exposed to space since the solar system's initial beginnings. On Mercury, remnants of the first massive bombardment have been found.
2. Mercury formerly had a deeper mantle and was a bigger terrestrial planet. During the early history of the solar system, a dwarf planet made a massive impact that robbed the planet of its mantle.
The existing surface of Mercury has been exposed to space since the very beginning of the solar system, which raises major issues once more.
Due to the factors in explanation 1, characteristics from the first significant bombardment have been found on Mercury. The quantity of low temperature volatiles that are trapped and sometimes sublimate out of the crust, causing hollows, is also a major issue. By such an impact, these low temperature volatiles—such as sodium, sulphur, magnesium, etc.—would have been completely pushed out.
3. A mostly iron-rich body developed, and "rock steam"—a gaseous mixture of atomic oxygen and silica—condensed and accreted onto it from the protoplanetary disk near the Sun. Small rock particles with lower temperature volatiles were subsequently formed into a crust. Additionally, it appears that iron was concentrated in the inner region of the protoplanetary disk by the Sun's early, extremely powerful magnetosphere.
Whilst there are a few minor issues with this, this appears by far the most likely scenario.
Its crust and mantle may have been significantly altered during its early history by massive collisions.
What is Core?The extremely hot and dense core of Earth is called the core. Under the mainly solid mantle and the chilly, brittle crust is the ball-shaped core. The radius of the core is about 3,485 kilometers, and it can be located around 2,900 kilometers (1,802 miles) beneath the surface of the Earth (2,165 miles). Earth is more ancient than the core.
Approximately 4.5 billion years ago, Earth was a uniform ball of hot rock. The ball warmed up considerably more due to radioactive decay and residual heat during planetary formation. After roughly 500 million years, the temperature of our new planet reached 1,538 degrees Celsius (2,800 degrees Fahrenheit), which is the temperature at which iron melts. The iron catastrophe refers to this critical moment in Earth's history.

What average emf (in volts) is induced, given the plane of the coil is originally perpendicular to the earth’s field and is rotated to be parallel to the field in 11 ms?
The average emf induced is "ωBA volts".if we know the value of ω, B & A we can easily calculate the value. Faraday's law of induction determines the typical emf produced by spinning a coil's turn in the earth's magnetic field.
Discussion:
According to this equation, the magnetic flux through a closed loop changes at a time rate equal to the negative of the induced emf in the loop.
When a coil is exposed to a magnetic field, it encounters a flux that is equal to the magnetic field's intensity times the area that the loop encloses times the Sine of the angle that exists between the standard to the region and the magnetic field.Calculation:
This flux value is constant and no electromagnetic field (EMF) is produced when the loop is positioned in the earth's magnetic field without moving. When the magnetic field starts rotating, the area and magnetic field strength stay constant, but the angle between the plane of the area's normal and the field lines continues to alter or fluctuate. Due to the magnetic flux's relationship to angle and the time dt at which an average emf is produced in the coil, this results in a change in the net magnetic field across the loop.
The flux φ = BAcosθ
E = - dφ/dt = - d(BAcosθ)/dt
As "B" & "A", both are constant
so, E= - BAd(cosθ)/dt
where, θ = the function of time
θ = ωt
where, ω = angular frequency (rad/sec)
E = -BAd(Cosωt)/dt
E = - (-ω)BA Sinωt = ωBA Sinωt
E = ωBASinωt
E = -d(BACosθ)/dt
The plane is now parallel to the field, and the normal is now perpendicular to the field.
θ=90°
Therefore, E= ωBASin90° = ωBA(1) = ωBA

Heat is transferred from the sun-warmed surface of the earth to the cooler overlying troposphere via conduction.
Heat transfer from earth to atmosphere:Conduction, convection, latent heating, and water phase transitions all help to carry heat from the Earth's surface, which has been warmed by the Sun, to the cooler troposphere above.
Latent heat flux is the worldwide transfer of latent heat energy via water and air currents. Here, we demonstrate how air circulation transports latent heat energy horizontally to cooler regions, where it condenses into rain or is deposited as snow, releasing the heat energy that was previously trapped there.
When air is heated from below by sunshine or by coming into contact with a warmer land or sea surface, convection occurs and the air below becomes less dense than the air above.

An organization is located in an area that experiences frequent and lengthy power blackouts. what will the effect of an electric generator be in this circumstance?
Electric utility power blackouts will result in short electric power outages for the organization.
Power blackouts :When the electrical power network, often known as the electrical grid, is down, there are power outages. Power outages can have a variety of causes, but they always tend to affect entire regions or cities rather than simply a single residence. For example, the Northeast blackout of 2003 left 50 million people without power from New York to Canada’s capital Ottawa.
A place experiences a blackout when all power is lost. Power outages of this kind generally affect a sizable population over perhaps extraordinarily broad areas. Blackouts are particularly difficult to quickly fix because they typically result from significant damage to electrical generation facilities (such as structural damage from violent wind storms or lightning strikes).

AC stands for “Alternating Current,” meaning voltage or current that changes polarity or direction, respectively, over time. AC electromechanical generators, known as alternators, are of simpler construction than DC electromechanical generators.
RMS or root mean square current/voltage of the alternating current/voltage represents the D.C current/voltage that dissipates the same amount of power as the average power dissipated by the alternating current/voltage. For sinusoidal oscillations, the RMS value equals peak value divided by the square root of 2.

When a proton slows from 0. 8c up to 0. 6c, it’s kinetic energy decreases by what factor of 1/4.
Kinetic energy of a proton having a charge Q and Voltage V is given by:
Kinetic energy = Q×V
Where, Q is the charge
V is the Voltage
Kinetic energy is directly proportional to the charge on a proton.
Let the kinetic energy of proton having charge 0.8C be KE₁ and kinetic energy of proton having charge 0.6C be KE₂
Hence KE₁ = 0.8 × V
KE₂ = 0.6 × V
Now, KE₁ / KE₂ = 0.8 V / 0.6 V
⇒ KE₁ / KE₂ = 4 / 3
⇒ KE₂ / KE₁ = 3/4
⇒ KE₂ = 3/4 times KE₁
Hence, the final kinetic energy becomes 3/4 times the initial kinetic energy.
The kinetic energy decreases by a factor of:

Atmospheric pressure is about 100000 pa. at h ≈ 10 m depth in water does this pressure double
Water pressure is the result of the weight of all the water above pushing down on the water below. As you go deeper into a body of water, there is more water above, and therefore a greater weight pushing down. This is the reason water pressure increases with depth.
The atmospheric pressure at a point is defined as the force acting normally on a unit area around that point, due to the total height of the air column of the atmosphere above it.
Pressure in depth = Atmospheric pressure + (rho) * g * h
where
rho = density of water
g = acceleration due to gravity
h = depth in water
P = Po + rho * g * h
2 * [tex]10^{5}[/tex] = [tex]10^{5}[/tex] + [tex]10^{3}[/tex] * 9.8 * h
h = 10.20 m
h ≈ 10 m

A circuit has an impedance of 5 ohms and a voltage of 100 volts. What is the current flow?
A circuit with an impedance of 5 ohms and a voltage of 100 volts has a current flow of 20 A.
The expression of an electronic component, circuit, or system's resistance to alternating and/or direct electric current is called impedance, indicated by the letter Z. Resistance and reactance are two distinct scalar (one-dimensional) phenomena that combine to form impedance, a vector (two-dimensional) variable.
[tex]Z^{}[/tex] = [tex]\frac{V}{I}[/tex]
(for a pure resistor where Z=R,preserving the form of the DC Ohm's law).
[tex]I=\frac{V}{Z}[/tex]
[tex]I = \frac{100}{5}[/tex]
I = 20 A
Therefore, A circuit with an impedance of 5 ohms and a voltage of 100 volts has a current flow of 20 A.
