PE=4.5(60)(9.8)PE=2646JIn classical physics, relative motion is absolute. For example, consider an object moving in a straight line with speed v0 on a platform. If the platform is moving with speed vp in the same direction relative to the ground, the object will be moving with speed v0 + vp relative to the ground. However, it is known that the speed of light is the same for all observers regardless of reference frame, which contradicts the classical model of relative motion. Which of the following statements is a conclusion that could be drawn from this contradiction?А. There are no absoluta celerence frames.B. All physical quantities are the same in al reference frames.C. Light can be described by a wave model and a particle model.D. Observers in different reference frames will measure time and distance differently.

A circular loop is initially placed in a uniform magnetic field perpendicular to the field lines and then removed quickly from the field. The induced emf causes the electric charge flow in the loop . Explain the force on the induced current due to the original field
Answers
The induced emf is found as -0.0531 V. When the flux coupling with a conductor or coil changes, electromotive Force, or EMF, is said to be induced.
What is induced emf?Emf is the production of a potential difference in a coil as a result of changes in the magnetic flux passing through it.
From Lenz law,the the induced EMF is found as;
[tex]\rm e=- \frac{\triangle \phi _B}{\triangle t } \\\\\rm e=- \frac{A\triangle B}{\triangle t } \\\\ e= -\frac{\pi r^2(0-1.10)}{0.15} \\\\ e=-0.0531 \ V[/tex]

The theoretical capacity of a process is the reciprocal of the theoretical flow time of the process. Do you agree? Explain.
Answers
I do not agree with the statement 'theoretical capacity of a process is the reciprocal of the theoretical flow time of the process' because time is only one variable.
What is theoretical capacity?The theoretical capacity of a process can be defined as the ability to perform a given work in a given period of time.
The theoretical capacity of a process is not only dependent on the time that takes to carry out but also on other variables (e.g., temperature, light conditions, etc).
In conclusion, I do not agree with the statement 'theoretical capacity of a process is the reciprocal of the theoretical flow time of the process' because time is only one variable.

Answers
Answer:
1 / i + 1 / o = 1 / f thin lens equation
(i + o) / o i = 1 / f
f = o i / (i + o) = 6 * -.4 / (-.4 + 6) = -2.4 / 5.6 = -.42 m
The focal length is -.42 m indicating a convex mirror

According to the diagram, voltmeter 1 will show 1.5 V. Because it is a series combination voltmeter 2 will also show 1.5 V.
What is a Voltmeter?The potential difference, or voltage, between two points in an electrical or electronic circuit is measured using a voltmeter, also referred to as a voltage meter. While some voltmeters are made for use in alternating current (AC) circuits, others are meant to be used in direct current (DC) courses. Voltage for radio frequency (RF) can be measured using specialized voltmeters.
A simple analog voltmeter is a high resistance connected in series with a sensitive galvanometer (current meter). A voltmeter needs to have high internal resistance. Otherwise, it will consume a sizable amount of current, interfering with the test circuit's performance. The range of voltages that the meter can display depends on the series resistance value and the sensitivity of the galvanometer.
Since all of the components in this series circuit are the same, any potential difference will be distributed equally i.e., (1.5V + 1.5V) / 2 = 1.5V

Answer:
5595 m
Explanation:
The wave travels down (the depth) and the back up (the depth again)

If a proton and an electron are released when they are 2.0 * 10-10 m apart (a typical atomic distance), find the initial acceleration of each particle.
Answers
The initial acceleration of proton and electron is 3.45 x 10¹⁸ m/s² and 6.33 x 10²¹ respectively.
What is electrostatic force?The electrostatic force F between two charged objects placed distance apart is directly proportional to the product of the magnitude of charges and inversely proportional to the square of the distance between them.
F = kq₁q₂/r²
where k = 9 x 10⁹ N.m²/C²
Given is the charge on proton and electron is q =1.6 x 10⁻¹⁹ C, distance r =2 x 10⁻¹⁰m , then the force will be
F = k q²/r²
Substituting the above values in the formula, we get the electrostatic force,
F = (9 x 10⁹) (1.6 x 10⁻¹⁹)²/(2 x 10⁻¹⁰)²
F = 5.76 x 10⁻⁹ N
The acceleration of electron when both proton and electron released is
acceleration = electrostatic force / mass of electron
Putting the values, we have initial acceleration of electron
a = (5.76 x 10⁻⁹)/(9.1 x 10⁻³¹)
a = 6.33 x 10²¹ m/s²
The acceleration of proton is due to the electrostatic force of attraction between proton and electron is given by
acceleration = electrostatic force / mass of proton
inserting the values, we get the initial acceleration
a '= (5.76 x 10⁻⁹)/( 1.67 x 10⁻²⁷)
a'= 3.45 x 10¹⁸ m/s²
Thus, initial acceleration of proton and electron is 3.45 x 10¹⁸ m/s² and 6.33 x 10²¹ respectively.

Answers
Assuming that all the bullet’s energy heats the paraffin, its final temperature is 27.1 degree C. The correct option is D.
What is temperature?Temperature is the degree of hotness and coldness of the material.
The energy of the bullet E = 1/2 mv²
E = 1/2 x 10 x 10⁻³ x (2000)²
E = 2 x 10⁴ J
This heat is used in heating the paraffin
E = m x c ΔT = m x c (Tfinal -Tinitial)
2 x 10⁴ J = 1 x 2.8 x 10³ x (Tfinal -20)
Tfinal = 27.1°C
Thus, the final temperature is 27.1 degree C. The correct option is D.
