radio waves of frequency 1.427 ghz arrive at two telescopes that are connected by a computer to perform interferometry. one portion of the same wave front travels 1.259 m farther than the other before the two signals are combined. part a will the two waves combine constructively or destructively?

Answers

Accordingly, the route difference is six times the wavelength. The value of m for the path difference between the two signals is 6 and indicates that the two waves combine positively.

The frequency of radio waves is 1.667 GHz

Prior to the path difference between the two signals being mixed, a single wave front travels 1.260 mm further than another.

Both positive and destructive interference can occur under certain circumstances.

The path difference between constructive and destructive interference is (n+1/2) times the wavelength for the former and n times the wavelength for the latter.

In this instance, wavelength can be determined as follows::

λ = c/f

λ  = 3 × [tex]10^{8}[/tex]/1.427 × [tex]10^{9}[/tex]

λ = 0.210m

If the floor were not frictionless, the sphere's angular speed would change and increase until the sliding between the sphere and the floor came to an end. As a result, correct option is C.

What is friction and what is the role it plays here?

When something moves over or rolls over another solid object, there is friction. Even though friction force can be advantageous, such as the traction needed to move without slipping, they also present a sizable amount of resistance to motion.

Friction between alloys appears to be primarily caused by the attraction forces, also called as stickiness, between the contact zones of the surfaces, which are always microscopically unequal. As the defects of the rough surface rub up against the softer surface, the "welded" seams are torn apart and friction is produced.

Answers

The corresponding values of the temperatures in 98.6°F and 102°F in Celsius scale are 37°C and 38.89°C

What is a temperature scale?

There are three temperature scales in use , Fahrenheit, Celsius and Kelvin. Fahrenheit temperature scale is a scale based on 32 for the freezing point of water and 212 for the boiling point of water, the interval between the two is 180.

In Celsius scale the freezing point is 0°C and the melting point is 100°C. The difference is 100

consider an idealized model with a bird emitting constant sound power, with intensity inversely proportional to the square of the distance from the bird. how many decibels does the sound level drop when you move 2.4 times as far away from the bird?

Answers

The sound level drops by 7.6 dB when we move 2.4 times as far away from the bird.

The decibel ratio of the measured sound intensity to the reference sound intensity is known as the sound intensity level (SIL), also known as the acoustic intensity level.

Let the initial distance be r₁ and the moved away distance be r₂. Then, r₂=2.4r₁.

Let the initial intensity be I₁ and the moved away intensity be I₂.

Then, the relationship between sound intensity and distance is,

[tex]\frac{I_2}{I_1}=\frac{{r_1}^{2}}{{r_2}^{2}}[/tex].

Let β₁ and β₂ be the two sound intensity levels. The difference in sound intensity is given by,

[tex]\begin{aligned}\beta_2-\beta_1&=\mathrm{10\;dB}\left(\log\frac{I_2}{I}-\log\frac{I_1}{I}\right)\\&=\mathrm{10\;dB}((\log I_2-\log I)-(\log I_1-\log I))\\&=\mathrm{10\;dB}\log \frac{I_2}{I_1}\end{alinged}[/tex]

Then, substitute, the I₂/I₁ value in the above equation.

[tex]\begin{aligned}\beta_2-\beta_1 &=(\mathrm{10\;dB})\log\frac{{r_1}^2}{{r_2}^2}\\&=\mathrm{10\;dB}\log\frac{{r_1}^2}{(2.4r_1)^2}\\&=(\mathrm{10\;dB})\log\left(\frac{1}{5.76}\right)\\&=-\mathrm{7.6\;dB}\end{aligned}[/tex]

Answers

The heat in joules transferred by a chemical reaction to the reservoir of a calorimeter containing 105 g of dilute aqueous solution is 1757.28 J.  

What is calorimeter?

Calorimeter is the device used to measure the heat during electrical, mechanical and chemical reactions and also to calculate heat capacity of the materials.

The heat transferred to a reservoir of a calorimeter can be calculated by,

Initial temperature (T1) = 21° C

Final temperature (T2) = 25° C

Change of temperature (ΔT) = T2 -T1 = 25 - 21 = 4° C.

Q = MC ΔT

where Q is the amount of heat transferred, C is the specific heat and ΔT is the change in temperature.

Q = 105g x 4.184 J/g° C x 4° C = 1757.28 J

Answers

For the beam that is attached to the wall from two ends the failure mode occurs at the point of application of force.

When a beam is attached to a wall on two ends, on both these points there is a normal force exerted by the wall on the beam. Therefore, any failure will occurs in between these two points due to an external force.

This failure or this maximum force that the beam can withstand can be found out by bending moment diagram. According to this diagram, the failure occurs at the mid-point of the beam. If the force is uniform or acting on the mid-point of the beam.

If the force is anywhere except at the mid-point then the failure occurs at the point of application of the force. The maximum force is present at the point of application and from the nearest end, the force linearly increases.

Answers

At Calvin cycle, temperature has a greater effect compared to light intensity.

Temperature regulates the rate of photosynthesis. The rate of photosynthesis increases with increased temperature. This is due to the fact that photosynthesis is a chemical reaction that is increased by temperature. At higher temperatures, the enzymes simply stop working and become denatured.

Furthermore, the temperature has an impact on the cycle. Because it relies on enzymes, temperatures that are either too high or too low will have an impact.

Meanwhile, a plant cannot photosynthesise efficiently if there is insufficient light even if there is enough of water and carbon dioxide and the temperature is appropriate. Increasing the intensity of the light raises the pace of photosynthesis until some other factor—a limiting factor—runs out.

Answers

The induced magnetic field strength 9.5cm radially outward from the center of the plates is  821.052 Tesla.

We know very well that when a charge is moving with some speed in particular direction then, it will induce a magnetic field around its environment. Only moving charge is able to produce magnetic field, stationary charge only produce electric field.

We know that magnetic field is given by=(μ/2πr)×(q/t) where

μ is called as magnetic field constant,

q is the induced charge in the capacitor,

and r is the distance between the two plates

So, we have r=9.5cm=0.095m,(q/t) =39C/sec and μ=4π×10⁻⁷Tesla-m/A.

So, on putting the above values, we get

(5 points) in the picture above, if n1 < n2 indicate which side of the wave front is traveling faster, the side of the wave front in medium 1 or in medium 2? (5 points) just as a turning car turns toward the slow-moving side, does the light turn toward or away from the surface normal as it passes from medium 1 to medium 2? draw the direction of the refracted ray (the direction of travel in medium 2) in the picture. (5 points) is there an incident angle such that there is no refracted light in this case? explain.

Answers

Moving from high n media to low n media is like moving from slow media to fast media. Such rays bend away from the normal.

Refraction of light when traveling from a fast medium to a slow medium bends the ray towards the normal boundary between the two media. The amount of bending depends on the refractive indices of the two media and is quantitatively described by Snell's law. When a wavefront enters a new medium at an angle, it changes direction.

When light hits an optically dense medium it bends toward the normal. When light enters an optically less dense medium it bends from a normal line. When light enters a material with a high index of refraction it slows down. Light bends towards the normal. When light enters a substance with a low index of refraction it accelerates. Light bends away from the normal.

if the load was too great for the motor, how could we reposition our load and what effect would it have on the reach of the robot?

Answers

Depending on the type of robot, we may use Grippers or Carts, reposition our load, and determine how this will affect the robot's reach.  To determine the impact on reach, specifics would be required.

Lever Arms/Grippers: By bringing the load closer to the base of the lever arm, the system's required torque can be reduced. To determine the impact on reach, specifics would be required. Is called Grippers

Carts: Relocating the load has no effect. To increase the cart torque available, increase the reduction gearing. Grippers, also known as hand grippers, are primarily used to measure and improve hand strength. It causes because of torque. One particular type of Carts strength is known as crushing grip, which is defined as a grip in which the four fingers, rather than the thumb, are the primary movers.

The kinematic equations are a collection of equations that explain the motion of an object with constant acceleration. Kinematics is a branch of physics that originated in classical mechanics and describes the motion of points, bodies, and systems of things without taking the forces that propel them. Kinematics is the study of the motion of mechanical objects, bodies, and systems without consideration of their related physical qualities and the forces acting on them. Kinematics equations need understanding of derivatives, rate of change, and integrals. The discipline, often known as the geometry of motion, employs algebra to mathematically represent these movements.

Answers

the magnetic flux density's induced emf across the coil is equal to 5e^-2t.

What does the term "magnetic flux" mean?

The magnetic flux across a surface in physics, specifically electromagnetism, is the surface integral of the normal component of the magnetic field B over that surface. The standard notation is B or. The weber is the SI unit for magnetic flux, and the maxwell is the CGS unit.

What connection exists between the magnetic flux density and the induced emf?

According to Faraday's law, induced EMF is equal to the rate at which magnetic flux changes. BA = Magnetic flux = Area x Magnetic field strength. As a result, induced EMF is calculated as follows: (change in Magnetic Flux Density x Area)/change in Time.

What are the 7 stages of the rock cycle?.

Answers

The 7 stages of the rock cycle are weathering, erosion and transport, deposition of sediment, burial and compaction, melting, uplift and deformation and metamorphism.

Weathering is a process of breaking down of rocks into smaller particles. Factors like temperature extremities, water and biological involvement of nature play an important role.

Erosion is a process of breaking down of rocks into sand-like particles. In the previous stage, water was only present as a factor for reactions to take place, while in erosion it acts as a transporting agent too.

Sediment is the constant deposition of small particles of sand, pebbles, that are broken down from rocks.

Burial and compaction happens when the sand particles are sedimented, they create layers which are soon covered by another layer of new sediments and the process goes on.

As soon as the rocks reach the bottom of the earth, the temperature rises and so does the pressure.

The process of forming a crust of earth upwards due to natural forces causing movement in the tectonic plates is called uplifting.

The constant pressure and sudden movements put some sedimentary and igneous rocks under great pressure. This stage is known as deformation and metamorphism.
