How would the self-inductance, l, of a coil change if you would increase its radius by a factor of two and increase its length by a factor of two?
The self-inductance of a coil will change by 8 times its original value by increasing its radius value by 2 and increasing the length of the coil by 2.
Self-Inductance: -
The definition of self-inductance is the induction of a voltage in a wire that carries current when the current in the wire is changing. In the instance of self-inductance, the circuit itself induces a voltage through the magnetic field produced by a changing current.
We know that the self-inductance of the coil is denoted by: -
L= µ *π*(r)^2*(N)^2*l
Where
L= Self-Inductance of the coil
µ= Magnetic Permeability Constant
r= Radius of the coil
l= Length of the coil
N= Number of turns of the coil
Here Self-inductance of the coil is directly proportional to the length of the coil and the square of the radius of the coil.
So,
On increasing the radius of the coil by a factor of 2 and the length of the coil by 2 the self-inductance of the coil increases by 8 times its original value.

The three paths taken by incoming solar radiation are:
Earth's surfaceAtmospheric gasesReflected backAbout 29 percent of the solar radiation that arrives at the top of the atmosphere is reflected back to space by clouds, atmospheric particles, or bright ground surfaces like sea ice and snow. This radiation plays no role in Earth’s climate system.
About 23 percent of incoming solar energy is absorbed in the atmosphere by water vapour, dust, and ozone, and
48 percent passes through the atmosphere and is absorbed by the surface. Thus, about 71 percent of the total incoming solar energy is absorbed by the Earth system.
Solar radiation, often called the solar resource or just sunlight, is a general term for the electromagnetic radiation emitted by the sun. Solar radiation can be captured and turned into useful forms of energy, such as heat and electricity, using a variety of technologies. However, the technical feasibility and economical operation of these technologies at a specific location depends on the available solar resource.

The resonant frequency of a driven rlcrlc circuit is 1600 hzhz. The resonant frequency is doubled if the resistance rr is doubled
The natural frequency at which a material vibrates with the greatest intensity is called the resonant frequency. The symbol for resonance is typically f0. Resonance is seen in items that are in balance with the forces at work and, in ideal circumstances, could vibrate indefinitely.
A resonant frequency is a natural vibrational frequency in sound applications that is established by the physical characteristics of the vibrating object.
The resonant frequency is advantageous because, in the event of resonance, the oscillation's deflection increases. In acoustics, a greater sound wave amplitude results in greater sound pressure and, thus, a greater volume. For loudspeakers, resonant frequencies are typically undesired.

What is the magnitude of the detected sound frequency shift from 170 hz during the projectile flight when a ball is thrown up in the air? a
The sound frequency shift's magnitude, or change in frequency, first decreases to zero before rising during the projectile flight when a ball is thrown up in the air
At this point, the frequency emitted by the source becomes equal to that received by the microphone. This can be seen from the equation 2 for Doppler effect contained in the attachment below.This moment is short lives and the projectile soon starts a return journey downward under the influence of gravity. The velocity of the projectile is negative ( v < 0 ) and from the equation can be confirmed that the frequency received by the microphone increases as the projectile fall under gravity. This is so because as the projectile falls downward it velocity becomes more and more negative. And from the equivalent in the picture below, the frequency received by the microphone increasesLearn more about sound frequency shift from:https://brainly.com/question/15743506

A car has 400 kgm/s worth of
momentum and runs into a truck initially at rest. After the collision,
the truck has 500 kgm/s
worth of momentum.
What must be the final momentum of the car?
A. 100 kgm/s
B. 500 kgm/s
C. -100 kgm/s
D. 400 kgm/s
Hello and Good Morning/Afternoon
Let's take this problem step-by-step:
By the Law of Conservation of momentum
⇒ the total momentum always remains constant before and after the
collision
Pc: the momentum of the car initially before collisionPcf: the momentum of the car after the collisionPt: the momentum of the truckPc = Pt + PcF
400 = 500 + PcF
PcF = -100 kg * m/s
Therefore the car's final momentum is -100 kg*m/s
Answer: -100 kg*m/s or choice (C)
Hope that helps!

When a small force is applied to a gyro, the result will instead occur 90 degrees ahead of that point, in the direction of rotation. this principle is known as:_____.
When a small force is applied to a gyro, the result will instead occur 90 degrees ahead of that point, in the direction of rotation. this principle is known as: Precession
What is precession?Precession is a shift in the direction of a rotating body's rotational axis. It can be described as a modification of the first Euler angle in the proper reference frame, while the rotation itself is defined by the third Euler angle. In other terms, a body is said to be precessing about a second axis if its own axis of rotation is spinning about that second axis. Nutation is a motion in which the second Euler angle varies. Precession can be either torque-free or torque-induced in physics.
