Explanation:

Answer 2

Mateo should place in the column of  marked cell is provides electrical energy.

What is electric current?

The current is a stream of electrons flowing from the positive terminal of the battery to the negative terminal.

The battery provides the voltage difference to make the current flow. The zigzag line shows the resistor which controls the electric current. The switch sign is used to stop the current at its position.

Thus the marked sign in front of battery or voltage source provides the electrical energy.

Carlota does 2000 J of work on a machine. The machine does 500 J of work. What is the efficiency of the machine?
A. 4%
B. 25%
C. 75%
D. 400%

Answers

A. 4% you divide 2000 to 500 and you get 4 which is your answer

Correct option is B. The efficiency of the machine is 25%, determined by dividing the work output (500 J) by the work input (2000 J) and then multiplying by 100 to get the percentage.

The efficiency of a machine is defined as the ratio of the work output to the work input, often expressed as a percentage. In this case, Carlota does 2000 J of work on the machine, and the machine does 500 J of work. To find the efficiency, we use the formula:

Efficiency (%) = (Work Output / Work Input) x 100

So, the calculation would be:

Efficiency (%) = (500 J / 2000 J) x 100 = 25%

The correct answer is B. 25%.

Answers

I think it is b , that what I would i pick

Answer:

Work output is less than work input.

Explanation:

Work output can never be greater than work input. Machines allow force to be applied over a greater distance, which means that less force will be needed for the same amount of work. When a machine changes the size of the force, the distance through which the force is exerted must also change.

20 C



12 C



0.2 C

Answers

Final answer:

If the current at a certain point is 2.0 A, then 20 C of charge flow past that point in 10 seconds, as current is the flow of charge per unit time.

Explanation:

The solution goes as follows: If the current at a certain point is 2.0 A, then the amount of charge that flows past that point in 10 seconds can be calculated using the relationship between current (I), charge (Q), and time (t), which is given by the formula I = Q/t. Therefore, to find the charge, Q, we rearrange the formula to Q = It. Plugging in the given values, we get Q = 2.0 A × 10 s = 20 C. This means that 20 coulombs of charge flow past the point in 10 seconds.

What was significant about the clay samples from the Western Hemisphere? How was the Alvarez hypothesis modified in response?

Answers

Final answer:

Clay samples from the Western Hemisphere are significant for studying ancient migration patterns, but they are not connected to the Alvarez hypothesis, which concerns the asteroid impact at the end of the Cretaceous period. The discussion of human migration into the Americas includes theories of both coastal and interior pathways. European contact led to diseases affecting the Indigenous population, with the post-colonization period marking the lowest numbers due to disease and conflict.

Explanation:

The significance of clay samples from the Western Hemisphere lies in their potential to provide insight into ancient migration patterns in the Americas. When discussing significant findings like clay samples or the Alvarez hypothesis, it's worth noting that the latter relates to the mass extinction at the end of the Cretaceous period, caused by an asteroid impact, rather than early human migration. Consequently, there's no direct modification of the Alvarez hypothesis in response to clay samples from the Western Hemisphere. In historical context, when dealing with human migration theories in the Americas, two predominant arguments arise: one supporting a coastal migration and the other an interior pathway. The debate over which came first remains unresolved, but both theories are supported by archaeological evidence.

As for the historical antecedents explaining why people in the Western Hemisphere became ill following contact with Europeans, it was largely due to a lack of immunity to diseases brought by Europeans, to which Indigenous populations had never been exposed. The year identified with the lowest population of Indigenous people varies according to different sources but is commonly placed after the European colonization, due to the devastating impact of disease, conflict, and dispossession.

A horse is running at 12m/s accelerated to 38m/s in 10 seconds. What is the horses acceleration.

Answers

Answer:

A horse is running at 12m/s accelerated to 38m/s in 10 seconds. What is the horses acceleration.

2.6m/s^2

When a  horse is running at 12 m/s accelerated to 38 m/s in 10 seconds, the horse's acceleration is 2.6 m/s².

What is acceleration?

Acceleration is the rate at which speed and direction of velocity vary over time. A point or object going straight ahead is accelerated when it accelerates or decelerates.

Even if the speed is constant, motion on a circle accelerates because the direction is always shifting. Both effects contribute to the acceleration for all other motions. Acceleration is a vector quantity since it has both a magnitude and a direction.

Initial speed of the horse = 12 m/s.

Final speed of the horse = 38 m/s.

Time interval = 10 seconds.

Hence,  the horse's acceleration is = change in speed/time interval

= (final speed - initial speed)/time interval

= ( 38 m/s - 12 m/s)/10 s

= 26/10 m/s²

= 2.6 m/s².

Answers

Answer:

 1, III, and v 

Explanation:

The will be repulsion of magnetic field at that region since the direction of magnetic field is perpendicular to the direction of current.

In regions symmetrically located between two circular wire loops with current flowing in opposite directions, it is possible for the net magnetic field to be zero.

The question involves finding the regions where the net magnetic field could be equal to zero when two circular metal wire loops each carry the same current I. According to physics, particularly the study of magnetism and Ampere's Law, the magnetic field around a current-carrying wire forms concentric circles. If two such loops carry current in the same direction, their magnetic fields at a point between them will add together. Contrarily, if the loops carry currents in opposite directions, the magnetic fields may cancel each other out at some point between them, resulting in a net magnetic field of zero.

Such a scenario is depicted in the provided example where two loops are shown with their respective magnetic fields acting in opposite directions at point P, yielding a net magnetic field of zero. Therefore, to answer the student's question, it is likely that the net magnetic field could be zero in a region that lies symmetrically between the two loops if the currents are flowing in opposite directions.

Explanation:

Given

Intensity level of rock concert [tex]=130\dB[/tex]

Intensity level of Whisper [tex]=2\dB[/tex]

Intensity of sound is given by

[tex]I=10\log _{10}(\frac{I}{I_o})[/tex]

where [tex]I_o=10^{-12}\ watts/m^2[/tex]

and difference in the intensity of the two sounds is [tex]db=130-2=128\ dB[/tex]
