What is magnetic field?A magnetic field is a vector field influence on moving charges and electric current.
We have given a motor inside it. The current I =30 M.
Circular coil having number of tens = 250 .
And the radius of each turn it is = 10 cm= 0.100
So we have to find the magnetic village trained to be at the center of the coil. So we know that the magnetic field

a. What is the work done by the force applied by the rope?
b. What is the work done by the frictional force?
c. What is the total work done on the crate?
Answers
The same formula of work can be applied to all the questions. The answers are:
E1. 100J
E2. 40N
E3. 5m
E4. a.) 360 J b.) 240 J c.) 120 J
El. If a horizontally directed force of 40 N is used to pull a box a distance of 2.5 m across a tabletop. The formula to get the much work that will be done by the 40 - N force will be
Work done = force x distance
Work done = 40 x 2.5
Work done = 100 J
E2. If a woman does 160 J of work to move a table 4 m across the floor. We will use the same formula to calculate the magnitude of the force that the woman applied to the table assuming the force is applied in the horizontal direction.
Work done = force x distance
160 = 4F
F = 160/4
Force F = 40 N
E3. Given that a force of 60 N used to push a chair across a room does 300 J of work. Same formula to get how far the chair move in this process.
Work done = force x distance
300 = 60 x distance
distance = 300/60
Distance = 5 m
Therefore, the chair moved 5m away.
E4. Given that a rope applies a horizontal force of 180 N to pull a crate a distance of 2 m across the floor. And a frictional force of 120 N opposes this motion.
a. The work done by the force applied by the rope can be found by
W = F x S
W = 180 x 2
W = 360 J
b. What is the work done by the frictional force?
W = \(F_{r}\) x s
W = 120 x 2
W = 240 J
c. What is the total work done on the crate?
W = (F - \(F_{r}\)) x distance
Where \(F_{r}\) = frictional force
Substitute all the parameters
W = (180 - 120) x 2
W = 60 x 2
W = 120 J

describe the energy transfers of an electron around a circuit when the switch is closed
Answers
Answer:
When a switch is closed, electrons move through a circuit from the negative side of a battery to the positive side
Explanation:
Note that current is marked to flow from positive to negative on circuit diagrams, but that's for historical reasons only. Benjamin Franklin did a fabulous job of understanding what was going on, but no one yet knew about protons & electrons, so he assumed current was flowing from positive to negative.
However, what really happens is electrons flow from negative (where they repel each other) to positive (where they are attracted).
As electrons flow through a circuit, they need 'something to do'. In many cases, that something is to light a bulb or heat an element, such as an element on a stove. So, the energy of an electron can be converted to heat or light.

Carbon-14 is the typical radioisotope used to date materials; however, it has a limitation to 40,000 years. A scientist who wants to date materials older than 40,000 years would most likely use which radioisotope? uranium-238 rubidium-91 iodine-131 cobalt-60
Answers
Answer:
the only one of these materials that allows studying processes of a very long period of time is Uranium 238
Explanation:
In a radioactive material, half of the atoms decay each life period, in carbon 14 this period T = 5730 years, so for a time of 40,000 years there are 7 life periods, so there are very few atoms left without decomposing .
To study older samples, materials with a longer life period are needed, let's show the visa time
²³⁸U T= 4.5 10¹⁰ years
⁹¹Rb T = 58 s
¹³¹I T= 8.04 days

g why can we ignore expanding of 13 l steel scuba tank when evaluating the mass of air the tank is filled with? is it a good approximation? explain.
Answers
The expansion of a 13L steel scuba tank can be ignored when evaluating the mass of air inside because the volume increase due to expansion is very small compared to the tank's original volume. It is a good approximation.
The expansion of a 13L steel scuba tank occurs due to changes in temperature and pressure. When the tank is filled with air, the air inside the tank is also affected by these changes. However, the volume increase due to expansion is typically very small compared to the original volume of the tank. As a result, the mass of air inside the tank can be evaluated without taking into account the expansion of the tank. This is a good approximation because the expansion is negligible in comparison to the total volume of the tank. However, it's worth noting that if a more precise calculation is required, the expansion of the tank should be taken into account.

In physics, the displacement of a moving body represents its change in position over time while accelerating. - Given initial velocity Vo in m/s, acceleration a in m/s2, and elapsed time t in s, the displacement of the body is: - Displacement = Vot+ 1/2 at2 Write a method displacement that accepts Vo, a, and t and computes and returns the change in position. - example: displacement (3.0, 4.0, 5.0) returns 65. 0 22
Answers
The method "displacement" calculates and returns the change in position of a moving body with initial velocity (Vo), acceleration (a), and elapsed time (t) using the formula: Displacement = Vot + 1/2 at^2.
The displacement of a moving body can be determined using the equation: Displacement = Vot + 1/2 at^2. Here's a step-by-step explanation of how to compute the change in position:
Begin by multiplying the initial velocity (Vo) by the elapsed time (t): Vot.
Next, calculate the term 1/2 at^2 by multiplying the acceleration (a) by half of the square of the elapsed time: (1/2) * a * t^2.
Add the two computed values together: Vot + (1/2) * a * t^2.
The resulting value is the displacement, representing the change in the position of the body over time while accelerating.
For example, let's consider the input values Vo = 3.0 m/s, a = 4.0 m/s^2, and t = 5.0 s:
Displacement = (3.0 * 5.0) + (1/2 * 4.0 * 5.0^2)
= 15.0 + (1/2 * 4.0 * 25.0)
= 15.0 + (2.0 * 25.0)
= 15.0 + 50.0
= 65.0 m.
Therefore, for the given example, the displacement of the moving body is 65.0 meters.

Calculate the energy of a photon of radiation with a frequency of 9. 50 x 10^13 hz.
Answers
The energy of a photon of radiation with a frequency of 9.50 x 10^13 hz is 6.3 x 10^-20 J.
What is photon?Photon is a type of elementary particle, or quanta, that makes up all forms of electromagnetic radiation, from gamma rays to visible light. Photons have zero rest mass and travel at the speed of light. They interact with matter through electromagnetic force. Photons are the basic unit of all electromagnetic radiation, and can be described by their frequency, wavelength, and energy. Photons are both wave-like and particle-like, and can be detected using a variety of techniques.
The energy of a photon is given by the equation E = hf (where h is Planck's constant and f is frequency). Therefore, the energy of the photon of radiation with a frequency of 9.50 x 10^13 hz is calculated as follows:
E = (6.63 x 10^-34 J.s) x (9.50 x 10^13 hz)
E = 6.3 x 10^-20 J
Therefore, the energy of a photon of radiation with a frequency of 9.50 x 10^13 hz is 6.3 x 10^-20 J.

Answers
The 950 W has higher resistance in the given situation.
What is a higher resistance?The current flow is inversely correlated with resistance. If abnormally high, damaged conductors from osicorron or burning could be one of a number of potential causes. Overheating is a problem that is frequently connected to resistance because all conductors emit some amount of heat.
What is a same resistance?When all linked devices, whether in parallel or series, are considered, the equivalent resistance is the value at which the total resistance between them is calculated. A circuit is fundamentally constructed as either a parallel or series circuit. Electrical resistance, which is the amount of energy required to carry charges or current through your devices, is visible.
