Shakib says that 25 meters per second is a velocity. Vania says that 25 meters per second is a speed. Who do you agree with?

Answer:

D) 3 ohms

Explanation:

According to one law

V = IR

Where V = voltage or potential difference

I =current

R =resistance

Making R the subject

R= V/I

R= 12/1.5

R=8 ohms

Sum of resistance of resistors in series equals the total resistance

R(total) = R1+ R2

8 =5+ R2

8-5=R2

Answer:Conduction

Explanation:the transfer of heat energy occurs between two objects that are touching.

Answer:

2 m/s^2, west

Explanation:

Vf=final velcoity

Vi=initial velocity

t=timw

\(a = \frac{vf - vi}{t} \)

=

\( \frac{15 - 25}{5} \)

= - 2 m/s^2

The - changes direction and makes it opposite

2 m/s, west

The magnitude of the object acceleration is -2m/s². Since the acceleration of the object is negative, hence the direction will be towards the west

Acceleration is the change in velocity of a body with respect to time. Mathematically;

\(a=\frac{v-u}{t}\)

v is the final velocity

u is the initial velocity

t is the time taken;

Given the following parameters

v = 15m/s

u = 25m/s

t = 5.0secs

Substitute the given parameters into the formula to have:

\(a=\frac{15-25}{5}\\a=\frac{-10}{5}\\a=-2m/s^2\)

Hence the magnitude of the object acceleration is -2m/s². Since the acceleration of the object is negative, hence the direction will be towards the west.

A brighter light source will result in a larger voltage drop across the resistor in a circuit with a phototransistor because the increased current flowing through the circuit causes a larger voltage drop according to Ohm's law.

If there is a single resistor in series with a phototransistor, a brighter light source would result in a larger voltage drop across the resistor.

The reason for this is that when the phototransistor is exposed to a brighter light source, more current will flow through the circuit because the phototransistor allows more current to pass through in the presence of a brighter light.

This increased current will cause a larger voltage drop across the resistor because the voltage drop across a resistor is directly proportional to the current flowing through it according to Ohm's law.

Ohm's law states that the voltage drop (V) across a resistor is equal to the current (I) flowing through it multiplied by the resistance (R) of the resistor:

V = IR.

Therefore, if the current through the circuit increases due to the brighter light source, the voltage drop across the resistor will also increase because the resistance of the resistor remains constant.

The voltage that is required to run the train is found to be 12V.

Since the transformer has 600 turns in the primary coil and 60 turns in the secondary coil, the turns ratio is 600:60, which simplifies to 10:1. To find the voltage required to make the train run, we need to use the turns ratio equation,

Vp/Vs = Np/Ns, The voltages of the primary and secondary coils are Vp and Vs, respectively. The primary coil has Np turns, while the secondary coil has Ns turns.

We know that the household voltage supplied to the train is 120 V, which is the voltage in the primary coil (Vp). We want to find the voltage in the secondary coil (Vs). Substituting the values we know into the turns ratio equation, we get,

120/Vs = 10/1

Simplifying this equation, we get,

Vs = 12 V

Therefore, the voltage required to make the train run is 12 V.

B. sugar + oxygen → carbon dioxide + water + energy

Explanation:

Energy is that which sustains living organisms, so as to perform various activities. One of the processes by which living organisms produce energy is by respiration.

Respiration involves the breathing-in of oxygen and breathing-out of carbon dioxide as a waste. The oxygen helps in breaking down molecules of carbohydrates e.g sugar in the system of living organisms into energy, carbon dioxide and water.

This process is well represented by the equation in option B.

The optical effect that is essential to the visual experience of motion pictures is known as Persistence of Vision.

Persistence of Vision (POV) is a phenomenon of the eye where an image or object is perceived by the brain for a short period of time after the image or object has been removed from the viewer's sight. The phenomenon occurs because of the retina's temporary retention of visual images even after they have been seen.

The Persistence of Vision enables the human eye to perceive the illusion of motion when viewing a series of still images in rapid succession. This effect is the foundation for the creation of motion pictures. In films, a sequence of still images is displayed in rapid succession (typically at a rate of 24 frames per second) that simulates motion to the human eye, tricking it into believing that the images are moving in a fluid and natural way.

POV is an essential aspect of the visual experience of motion pictures as it allows filmmakers to create an illusion of motion using a series of still images. The human eye is capable of retaining images for a short period of time after they have disappeared from the field of vision, which makes this effect possible.

Jim is displaying detached listening as he is being physically present in conversation with his academic advisor but his focus is elsewhere, particularly, his phone.

The style of listening that Jim is displaying is detached. This is because he is not paying attention to his advisor and is instead distracted by his phone. Detached listening is when one is physically present in a conversation but not mentally or emotionally engaged. Examples include browsing on the phone or thinking about other things while someone is talking.

In contrast, active or involved listening would involve fully concentrating, understanding, responding, and then remembering what is being said. Considering that Jim is mainly focused on his phone, he is not displaying any signs of this type of engagement with his advisor, hence, detached is the appropriate choice to describe his listening style.

Thanks theres your answer

Answer:

Push-ups. Let M1 be the mass of the body and M2 be the mass of weights. Assume that M1 must be heavier than M2. Since M1 is heavier, M1 requires more force, and therefore work to be applied, let F1=M1*g. To bring our body back up, we need a force bigger or equal (if already in motion) to F1.

Let F2 = M2*g

Since F1 has to be bigger than F2 due to mass, we can build an equation for energy. Let X be a displacement, which is equal in both situations. Constructing a change of energy equation we can see that work done to lift the body is greater:

W1=F1*x

W2=F2*x

Where W1 is the work of the hands-on body, and W2 is the work of lifting weights. W1 has to be larger than W2. Since more work in W1, more muscle will be needed to complete a repetition, but only assuming that M1 > M2.

MRI systems are generally thousands of times stronger than a refrigerator magnet. The strength of a magnet is measured in units called Tesla (T). A typical refrigerator magnet has a magnetic field strength of around 0.001 Tesla or 1 milliTesla (mT).

In contrast, MRI systems used in medical imaging operate at much higher field strengths, typically ranging from 1.5 Tesla to 3 Tesla or even higher.To put it into perspective, a 1.5 Tesla MRI scanner is approximately 1500 times stronger than a refrigerator magnet, while a 3 Tesla MRI scanner is approximately 3000 times stronger. These high magnetic field strengths are necessary for producing detailed and high-quality images of the body's tissues and organs during an MRI examination.It's worth noting that the strength of an MRI system can vary depending on the specific model and technology used. Advanced MRI systems with even higher field strengths, such as 7 Tesla or 9.4 Tesla, are also available for specialized research and clinical applications. These extremely high-field MRI systems are significantly stronger than a refrigerator magnet, often by tens of thousands of times.
