The resistance of an ammeter should be low. This is because an ammeter is connected in series with the circuit for the measurement of electric current. In case, its resistance is high, then some amount of current may lost in heating it leading to the inaccurate reading. An ideal ammeter is one which has zero resistance.

Let's calculate the equivalent resistances on both circuits.

On Diagram A we have a series connection of the resistors. The equivalent resistance will be the sum of all resistances:

\(R_{eq}=1+1+1\\\\\boxed{R_{eq}=3\Omega}\)

On diagram B we have a parallel connection of the resistors. The reciprocal of the equivalent resistance will be the sum of the reciprocals of all the resistances:

\(\frac{1}{R_{eq}} = \frac{1}{1} +\frac{1}{1} +\frac{1}{1} \\\frac{1}{R_{eq}}=3\\\\\boxed{R_{eq}=\frac{1}{3}}\)

Therefore, the larger resistance occurs on diagram A.

For the current, recall

\(V=IR\)

Where \(I\) stands for current \(R\) is the resistance and \(V\) is the voltage. Rearranging the equation we have

\(I = \frac{V}{R}\)

We can see that the larger the resistance, the smaller the current gets. So the larger current must happen in the diagram with smaller resistance. Therefore, the larger current occurs on diagram B.

The power cycle shown in the figure represents a type of internal combustion engine, commonly used in automobiles. It consists of four processes: intake, compression, combustion, and exhaust. During the intake process, the piston moves downward, drawing in a mixture of air and fuel. Then, during the compression process, the piston moves upward, compressing the air-fuel mixture. The compression causes an increase in temperature and pressure, which is necessary for the combustion process.

Next, during the combustion process, a spark ignites the compressed air-fuel mixture, causing it to rapidly expand and push the piston downward. This is where the engine produces power to turn the wheels of the vehicle. Finally, during the exhaust process, the piston moves upward again, pushing the burnt gases out of the cylinder.

The efficiency of this power cycle can be improved by using various techniques such as turbocharging, supercharging, and direct fuel injection. These techniques increase the amount of air and fuel entering the engine, resulting in more power output. However, they also increase the temperature and pressure inside the engine, which can cause problems such as knocking and engine damage.

Overall, the power cycle shown in the figure is an important process in internal combustion engines. It has undergone many improvements over the years, and continues to be a crucial part of transportation and many other industries.

Hi there!

1)

Since the charge placed in the middle is positive, we know that the particle is being repelled.

The particle experiences a greater repelling force by the 9μC charge. We can use the equation for electric force:
\(F_E = \frac{kq_1q_2}{r^2}\)

k = Coulomb's Constant

q₁, q₂: Charges (C)
r = distance between charges (m)

This is a VECTOR quantity, so we must subtract the forces since they point in opposite directions.

Force from 9μC particle:
\(F_E = \frac{k(.000005)(.000009)}{2^2} = .101\\\\\)

Force from 4μC particle:
\(F_E = \frac{k(0.000005)(0.000004)}{2^2} = 0.0450\)

Subtract:
\(.101 - 0.0450 = \boxed{0.561 N}\)

2)

We can find a position by setting the two equations equal to one another. (Both repelling forces must be EQUAL for the force = 0 N)

Let the distance between the 9μC and 5μC charge equal 'x', and the distance between the 4μC and 5μC charge equal '4 - x'.

\(\frac{k(0.000009)(0.000005)}{x^2} = \frac{k(0.000004)(0.000005)}{(4 - x)^2}\)

Cancel out 'k' and the 5μC value.

\(\frac{0.000009}{x^2} = \frac{0.000004}{(4 - x)^2}\)

Solve for 'x' using a graphing utility.

\(\boxed{x = 2.4 m}\)

Answer:

Explanation:

The type of force in the given scenario is tension. The correct option is c.

Tension is defined in physics as the pulling force conveyed axially by a string, cable, loop, or similar material, or by every end of a rod, truss member, or similar three-dimensional object.

Tension can also be defined as the action-reaction pair of forces acting at each end of said elements.

Newton's second law states that the tension in the rope must equal the weight of the backed mass.

Tension, the normal force, and friction are all examples of contact forces.

Since the weight is not moving, the acceleration is zero. Even if the acceleration is not zero, this equals zero.

Thus, the correct option is c.

The tune-up specifications of a car call for the spark plugs to be tightened to a torque of 38 Nm. You plan to tighten the plugs by pulling on the end of a 25 cm wrench. Because of the cramped space, you need to pull at an angle of 120 degrees with respect to the wrench shaft. You would need to pull with a force of 219 Newtons.

To determine the force required to achieve a torque of 38 Nm using a wrench, we need to consider the principles of torque and the angle at which the force is applied.

The formula for torque is given by:

Torque = Force × Distance × sin(θ),

Given:

Torque = 38 Nm,

Distance = 25 cm = 0.25 m,

θ = 120 degrees.

Let's solve for the force (F):

38 Nm = F × 0.25 m × sin(120 degrees).

To calculate sin(120 degrees), we need to convert the angle to radians:

120 degrees = (120 degrees × π) / 180 = 2π/3 radians.

38 Nm = F × 0.25 m × sin(2π/3).

F = (38 Nm) / (0.25 m × sin(2π/3)).

F ≈ (38 Nm) / (0.25 m × 0.866).

F ≈ 219 N.

Therefore, you would need to pull with a force of approximately 219 Newtons to achieve the specified torque of 38 Nm using the 25 cm wrench at an angle of 120 degrees.

An incline plane makes loading a piano into a truck easier by reducing the amount of force required.

When loading a piano onto a truck, an inclined plane, such as a ramp, can significantly ease the process. The incline plane reduces the effort needed to lift the piano vertically by allowing it to be moved up gradually along the ramp. This transformation of the lifting task into a more manageable horizontal pushing or pulling task reduces the force required. As the piano sits on the ground, it possesses gravitational potential energy due to its height above the ground. However, as it is moved up the incline, some of the potential energy is converted into kinetic energy, specifically the energy of motion. Once the piano is fully loaded into the truck, it will remain there with the potential energy unchanged, but with a lower kinetic energy, as it comes to a stop.

Efficiency of Heat Exchanger are as below:

the heat exchange process between two fluids with different temperatures using solid walls occurs in various engineering applications. The tool to achieve this exchange is a heat exchanger. Some applications like air conditioning, power generation, waste heat recovery, and chemical processing use this device.

The basis of the work of a heat exchanger is that the hot fluid enters the heat exchanger at temperature T1 and its heat capacity is Chot. Also, the cold fluid with the heat capacity of Ccold enters temperature t1; in the meantime, the hot fluid loses its heat, and its temperature drops to T2.

• When 10Ω and 20Ω are connected in parallel and 15Ω in series, we have:

R1 = 10 Ω

R2 = 20 Ω

R3 = 15 Ω

Answer:

Light consists of photons, which are produced when an object's atoms heat up. Light travels in waves and is the only form of energy visible to the human eye.

Explanation:

Now What is light?

-Light ( or light energy ) is defined as a form of electromagnetic radiation and a type of kinetic energy.

-Light is made up of photons. Photons is the basic unit of light. They are produced when an object's atom is subjected to heat. The more the atoms are heated, the more photons are created.

-Light travels in the form of a wave but it does not require any medium for transmission.

-Light travels so fast, nothing is faster than it. It travels at a constant speed of 186,282 miles/sec ( 300,000 km/sec ) in vacuum and whether the source is moving or stationary.

-Light can be measured in either joules, calories ( energy units ), quanta and einsteins ( quantum units ). Conversion from one unit to another heavily depends on wavelength.

Now an unaided human eye can only see the visible light, namely red, orange, yellow green, blue, indigo and violet (Roy G Biv) but light also comes in other forms that we cannot see, they are named, radio wave, microwave, infrared, ultraviolet, x-ray and gamma ray.

If the linear momentum of a system is quadrupled, it means that the product of mass and velocity of the system has been increased by a factor of 4.

However, the change in kinetic energy (K.E) will depend on the type of system and whether the change in momentum is due to an external force or an internal interaction.

In general, if the increase in momentum is due to an external force acting on the system, then there will be an increase in kinetic energy as well. This is because work is being done on the system by the external force, which increases its energy. The exact amount of increase in kinetic energy will depend on the nature of the force and the distance over which it acts.

On the other hand, if the increase in momentum is due to an internal interaction within the system, then the change in kinetic energy may be less predictable. This is because the internal forces may be conservative and result in a redistribution of energy within the system rather than an overall increase.

Therefore, without knowing the specifics of the system and the source of the change in momentum, it is difficult to determine how much the K.E will change.
