two resistors of resistance 3 ohm and 6 ohm are connected in parallel. Which resistor would absorb the greatest power

The mass of the given will be 20kg.

By using formula,

force = mass x acceleration

mass = force / acceleration

mass = 400 N / 20m/s²

mass = 20 Kg

Acceleration is the rate at which an object's velocity with respect to time changes. They are vector quantities, accelerations. The direction of the net force acting on an object determines the direction of its acceleration.

Any process where the velocity changes is referred to as acceleration. There are only two ways to accelerate: changing your speed or changing your direction, or changing both. This is because the velocity is both a speed and a direction.

When relay operations are no longer needed, the first apparatus that should be discontinued is B, the relay pumpers that are first in line.

This is because the first pumpers in line are the ones closest to the water source and are used to establish the relay, while the last pumpers in line are used to maintain the relay and deliver water to the fire scene. Therefore, once the relay has been established, the first pumpers in line are no longer needed as the remaining pumpers can maintain the water supply to the fire scene.

It is important to note that discontinuing any apparatus should be done in consultation with the incident commander to ensure that the water supply is still sufficient to effectively fight the fire. If the water supply is insufficient, it may be necessary to keep all pumpers in line or even call for additional resources to maintain the water supply.

Overall, the decision to discontinue any apparatus during relay operations should be based on the needs of the incident and the available resources to effectively fight the fire.

Answer:

B. Neutron has no charge

Answer:

B. Neutron

Explanation:

Firstly, the nucleus is what contains the protons and electrons, so it is not an atomic particle. The electron has a negative charge, and the proton has a positive charge (you can remember this by looking at its prefix 'pro'). This means the neutron has no charge (think of it as neutral).

B The Mustang, because it has the largest ratio of force to mass car is capable of the largest acceleration

On a dynamometer, engine torque is measured at constant speed. Powertrain The quantity necessary to accelerate the inertia of the spinning components reduces the actual torque provided to the drivetrain.

Standard automobile and truck engines generally provide 100 to 400 lb-ft of torque. The crankshaft of an engine is continually rotated (or twisted) by the pistons inside the engine as they reciprocate up and down on it.

Therefore, your automobile will accelerate faster the more torque it has. The ability of an engine to manage a load and produce a specific amount of power to rotate the engine on its axis is represented by torque, which is an essential component of producing power from a car's engine.

Explanation:

In this scenario, the organist is sitting 0.820 m away from the south wall and there is a mirror mounted on the south wall that is 0.600 m wide. The mirror is placed in such a way that it reflects the image of the B standing against the north wall towards the organist. Therefore, the organist can see the reflection of the choir through the mirror.
 
To calculate the width of the north wall that the organist can see, we need to use the concept of similar triangles. The distance between the north and south walls is 6.50 m, and the distance between the mirror and the choir is the same as the distance between the organist and the mirror (0.820 m). Let's call the width of the north wall that the organist can see "x".
Using similar triangles, we can set up the following equation:  x/0.820 = 0.600/6.50
Solving for "x", we get:  x = 0.057 m or 5.7 cm
Therefore, the organist can see a width of 5.7 cm of the north wall through the mirror.

According to the principle of selective attention, as attention is focused on one object, all other features drop or recede into the background.

The principle of selective attention suggests that our attentional resources are limited, and we selectively focus on specific stimuli while filtering out others. When we concentrate our attention on one object or feature, it becomes the center of our focus, while other features or objects in the background are less noticeable or fade away. This phenomenon is known as "inattentional blindness" or "change blindness," where we may fail to perceive or remember unattended stimuli. Selective attention allows us to prioritize and process relevant information while disregarding irrelevant or less important features, enhancing our ability to focus on specific aspects of our environment.

The principle of selective attention explains that when we direct our attention to one object, other features or objects recede into the background, illustrating the limited capacity of our attentional resources.

Cutting a magnet in half creates two new magnets, each with one north pole and one south pole.

When you cut a magnet in half between the north and south poles, you effectively create two new, smaller magnets. Each of these new magnets will have its own north pole and south pole.

This happens because the magnetic domains within the magnet reorient themselves, forming two separate magnetic fields with distinct north and south poles.

In essence, cutting a magnet does not eliminate its poles; rather, it results in the creation of two new magnets, each possessing a north and a south pole.

A permanent bar magnet with the south pole pointing downward is dropped through a Solenoid, as shown in the illustration.

The direction of the induced current that would be measured in the ammeter as the magnet falls completely through the solenoid is given by the left-hand rule.

According to this rule, if the thumb of the left hand points in the direction of the force on a positive charge, then the fingers will point in the direction of the magnetic field that is generating the force, and the palm will face in the direction of the motion of the charge.

The magnetic field in the solenoid is perpendicular to the direction of motion of the magnet, and the force generated is towards the center of the solenoid. Therefore, the induced current that would be measured in the ammeter as the magnet falls completely through the solenoid is in a clockwise direction.

As the current flowing through the resistor changed, the potential difference across the resistor also changed.

According to Ohm's Law, the potential difference across a resistor is directly proportional to the current flowing through it. Therefore, if the current flowing through the resistor increases,

the potential difference across it will also increase, and vice versa. This agrees with my prediction because it is a fundamental principle of electrical circuits.

However, it is important to note that this relationship holds true only for resistors that follow Ohm's Law. For non-Ohmic resistors, the relationship between potential difference and current may not be linear, and may depend on other factors such as temperature or frequency.

The amount of heat absorbed by the gold ring can be calculated using the formula:

Q = mcΔT

where Q is the heat absorbed, m is the mass of the gold ring, c is the specific heat capacity of gold, and ΔT is the change in temperature.

To find the mass of the gold ring, we can use the formula:

\(\[V = \frac{m}{ρ}\]\)

where \(V\) is the volume of the gold ring and \(ρ\) is the density of gold.

Given:

Volume of the gold ring (V) = 1.91 cm³

Density of gold (ρ) = 19.3 g/cm³

Change in temperature (ΔT) = 27.3 °C - 10.0 °C = 17.3 °C

Specific heat capacity of gold (c) = 0.129 J/g°C

First, let's calculate the mass of the gold ring:

\(\[m = V \times ρ = 1.91 \, \text{cm}³ \times 19.3 \, \text{g/cm}³\]\)

The average acceleration of the baseball during the throwing motion is approximately 635.2 m/s^2.

We can use the following equation to calculate the average acceleration of the ball,

a = (v_f - v_i) / t

where a is the average acceleration, v_f is the final velocity (in this case, the velocity of the ball when it is released), v_i is the initial velocity (in this case, the velocity of the ball when it is behind the pitcher's body and has not yet been thrown), and t is the time taken to throw the ball.

We know that the speed of the ball when it is released is 42 m/s, and we can assume that it starts from rest when it is behind the pitcher's body.

v_f = 42 m/s

v_i = 0 m/s

We also know that the ball is thrown through a displacement of 3.5 m, and we can estimate the time taken to throw the ball using the average speed of the throwing motion. Let's assume that the average speed of the throwing motion is half the speed of the ball when it is released, or 21 m/s. Then, the time taken to throw the ball is,

t = d / v_avg

t = 3.5 m / 21 m/s

t = 0.1667 s

Now we can plug in our values for v_f, v_i, and t to find the average acceleration,

a = (42 m/s - 0 m/s) / 0.1667 s

a = 251.99 m/s^2

The acceleration due to gravity is approximately 9.81 m/s^2, so we can add this to our previous calculation to get,

a_avg = a + g

a_avg = 251.99 m/s^2 + 9.81 m/s^2

a_avg = 635.2 m/s^2
