What is the mass of an object that experiences a gravitational force of 685 n near earth's surface where g = 9.80 m/s2?

Answers

Answer 1

The mass of an object that experiences a gravitational force of 685 N near earth's surface where g = 9.80 m/s² is 98.89 kg.

What is gravitational force?

Any two mass-containing objects are attracted to one another by the gravitational force. Because it consistently attempts to pull masses together rather than pushing them apart, the gravitational force is known as attractive.

In reality, everything in the cosmos is tugging on everything else, including you!

According to the question,

The gravitational force of 685 N near earth's surface.

The acceleration due to gravity is  g = 9.80 m/s².

The formula for force acting of the body under the influence of gravitation is ;

Force = mass×acceleration

Substitute the given values;

685 = m×9.8

m = 685/9.8

m = 69.89 kg.

Therefore, mass of an object is 69.89 kg.

An electron is ejected from the cathode by a photon with an energy slightly greater than the work function of the cathode. How will the final kinetic energy of the electron upon reaching the anode compare to its initial potential energy immediately after it has been ejected?.

Answers

The kinetic energy of the ejected electron (photoelectron) is equal to the energy of the photon minus the work function (E required to eject the photoelectron).

The  process of final kinetic energy of the electron upon reaching the anode compare to its initial potential energy immediately after it has been ejected -

The electron has a lot of potential energy and very little kinetic energy when it is liberated from the cathode (as it is not moving yet or moving very slowly). We are currently on the left side of the picture above. The electron accelerates and speeds up as it goes away from the cathode and toward the anode. As a result, the kinetic energy rises.The electron is likely to have the highest kinetic energy and the lowest potential energy when it reaches the anode.Therefore, the kinetic energy at the end of the electron's journey is approximately equal as the potential energy at the beginning (when the electron was released).

The reason the position of a particle cannot be specified with infinite precision is the?

Answers

The reason the position of a particle cannot be specified with infinite precision is the uncertainty principle .

The position of a particle moving in a straight line is a vector which represents a point P on the line in relation to the origin O. The position of a particle is often thought of as a function of time, and we write x(t) for the position of the particle at time t.

The Heisenberg uncertainty principle is a law in quantum mechanics that limits how accurately you can measure two related variables. Specifically, it says that the more accurately you measure the momentum (or velocity) of a particle, the less accurately you can know its position, and vice versa.

The uncertainty principle (for position and momentum) states that one cannot assign exact simultaneous values to the position and momentum of a physical system. Rather, these quantities can only be determined with some characteristic “uncertainties” that cannot become arbitrarily small simultaneously

How would you position a flat loop of wire in a changing magnetic field so that there is no induced emf in the loop?

Answers

Position the loop so that the field lines run perpendicular to the area vector or parallel to the surface so that there is no induced EMF in the loop

Magnetic Field is the region around a magnetic material or a moving electric charge within which the force of magnetism acts.

Flux is the presence of a force field in a specified physical medium, or the flow of energy through a surface. In electronics, the term applies to any electrostatic field and any magnetic field . Flux is depicted as "lines" in a plane that contains or intersects electric charge poles or magnetic poles.

As we all know that a moving charged particle will experience force by a magnetic field, the magnetic field produced by the field coil remains constant, that is, no force is experienced by electrons of the wire. So, we have to produce a relative motion between magnetic field and electrons.

Whenever the flux passing through the coil changes by any way (like either changing angle, magnetic field or area of coil), we are actually producing a relative motion between electrons and magnetic field. As a result, the electrons experience a magnetic force and shift to produce

flux =  [tex]\int\limits {BAcos(theta)} \,[/tex]

theta = angle between magnetic field and area

Since we know , EMF get induced only when flux changes , if their is no flux change , no EMF can be induced

Hence , in order to not induce any kind of EMF ,we need to maintain a constant flux , but in question it is a changing magnetic field which means changing flux ,in this situation we need to align a flat loop parallel to magnetic field so , their is zero flux through the loop .

A stereo speaker is placed between two observers who are 40 m apart, along the line connecting them. if one observer records an intensity level of 59 db, and the other records an intensity level of 83 db, how far is the speaker from each observer?

Answers

The distance from observer A of intensity of sound 59 db is 28.64 m and the distance from observer B of intensity of sound 83 db is 11.36m

Explanation:

Let's solve this problem in parts

let's start by finding the intensity of the sound in each observer

observer A β = 59 db

            β = [tex]10 log\frac{I_a}{I_o}[/tex]

where I₀ = [tex]1 \times 10^{-12}[/tex]  W / m²

             [tex]I_a = I_b \times 10 ^{ \frac{\beta}{10} }[/tex]

             [tex]I_a = 1\times 10 ^{-12} \times 10 ^{ \frac{59}{10} }[/tex]

             [tex]I_a[/tex] = [tex]2.51 \times 10 ^{-6}[/tex] W / m²

Similarly for Observer b [tex]I_b = 3.16 \times 10 ^ {-4}[/tex]

now we use that the emitted power that is constant is the intensity over the area of ​​the sphere where the sound is distributed

P = I A

therefore for the two observers

the area of ​​a sphere is

[tex]A= 4\pi \times r^2[/tex]

we substitute the above formula, we get

Let us call the distance from the observer A be to stereo speaker = x, so the distance from the observer B to the stereo speaker = 40- x; we substitute

            [tex]I_a (35 -x) ^2 = I_b x^2[/tex]

after solving the above equation we get  x = 28.64 m

This is the distance of observer A

similarly The distance from observer B is 35 - x

= 40 - 28.64

= 11.36m

The distance covered by a car moving with a speed of 36 km/h in 15m is (a) 0.9 km (b) 9.0 km (C) 90 km (d) 900 km​

Answers

Given :

Speed of a car = 36 km/h

Time taken = 15 minutes

Converting the time into hour:-

= 15/60 hours

As we know that,

Distance = Speed × Time

= (36 × 1/4) kilometres

= 9 kilometres

Hence the distance covered is 9 kilometres.

Option b) 9.0 km

This is a uniform rectilinear motion exercise.

To start solving this exercise, we obtain the following data:

Data:v = 36 km/hd = ¿?t = 15 min = 0.25 hr

                                     Minutes to hour converter

                                                  60 min = 1 hour

                                       [tex]\boldsymbol{\sf15\not{min}*\dfrac{1 \ hr}{60 \not{min}}=0.25 \ hr }}[/tex]

To calculate distance, speed is multiplied by time.

We apply the following formula: d = v * t

We substitute our data into the formula:

                                     [tex]\boldsymbol{\sf{d=v*t}}[/tex]

                                     [tex]\boldsymbol{\sf{d=36 \dfrac{km}{\not{h}}*0.25 \not{h} }}[/tex]

                                     [tex]\boldsymbol{\sf{d=9 \ km}}[/tex]

The distance traveled by a car moving with a speed of 36 km/h in 15 m is 9 km.

Therefore, the correct option is "B".

When the paper is turned [tex]25^{o}[/tex] with respect to field, then the flux through it can be calculated as follows -

Φ = 25 x cos ([tex]25^{o}[/tex]) = 22.67 [tex]Nm^{2} /C[/tex].

Hence, the flux through the paper will be 22.67 [tex]Nm^{2} /C[/tex].
