Energy BalanceTo check if the ANSYS solution satisfies total energy balance, add a Reaction Probe for the left boundary. Make sure to set the thickness to 1m. The thickness is necessary to convert from heat flux to heat flow as discussed in the 2D Conduction module.What is the reaction at the left boundary (in W)? Please input your answer in decimal notation (e.g. 18.65).This reaction value implies that the energy balance for the entire domain is satisfied exactly as discussed under Big Ideas: Finite Element Analysis > Finite Element Solution > Reaction. But we saw that this does not imply that energy balance is satisifed for each element.

The average speed of April, given the data from the question is 13.33 m/s

Speed is the distance travelled per unit. Mathematically, it can be expressed as:

Speed = distance / time

Average speed is simply defined as the total distance travelled divided by the total time taken to cover the distance .

Average speed = Total distance travelled / total time

From the question given above, the following data were obtained:

Average speed = Total distance travelled / total time

Average speed = 1600 / 120

The lead that monitors an electrode at the 5th intercostal space on the left mid-clavicular line is called V4.

The electrocardiogram (ECG) is a diagnostic tool that measures the electrical activity of the heart. It uses electrodes placed on the chest, arms, and legs to record the heart's electrical signals. The standard ECG has 12 leads that monitor different areas of the heart. V4 is one of the six precordial leads that are placed on the chest. It is positioned at the 5th intercostal space on the left mid-clavicular line and monitors the electrical activity of the heart's anterior wall, specifically the left ventricle. V4 is important for detecting abnormalities such as myocardial infarction, ischemia, or arrhythmias.

The greenhouse effect is the way in which heat is trapped close to Earth's surface by “greenhouse gases.” These heat-trapping gases can be thought of as a blanket wrapped around Earth, keeping the planet toastier than it would be without them. The greenhouse effect is a process that occurs when energy from a planet's host star goes through its atmosphere and warms the planet's surface, but the atmosphere prevents the heat from returning directly to space, resulting in a warmer planet.

Answer:

the greenhouse effect is the warming of the earth's surface and atmosphere which is caused by the presence of water vapour, carbon dioxide and certain other gasses

When the spindle contacts the anvil on a standard SAE micrometer, the measurement of the object being measured can be taken.

The spindle is the movable part of the micrometer that comes into contact with the object, while the anvil is the fixed part that provides a stable surface for the object to rest against. The micrometer uses a calibrated screw mechanism to provide precise measurements in units of thousandths of an inch (or millimeters, depending on the type of micrometer).

Therefore, when the spindle contacts the anvil, the measurement can be read off the micrometer's scale or digital display, giving the exact size of the object being measured with a high degree of accuracy.

Explanation:

Answer: 1 2 5

Explanation:

Galileo Galilei, an Italian physicist, is credited with being the first to calculate speed by dividing it by the distance traveled and the time required. Galileo defined speed as the distance covered in a predetermined period of time. Thus option A, B. E is correct.

Speed is determined by dividing the distance by the time. Calculating the units for speed requires knowledge of the units for both time and distance. Since the distance is measured in meters (m) and the time is measured in seconds, the units in this example will be meters per second (m/s) (s).

That is speed = distance time. Alternatively, you can calculate the time by dividing the distance traveled by the speed. You can figure out the third input if you know two of the inputs.

Therefore,  For instance, if a car drives 120 miles (ca. 193 km) in 2 hours, we may calculate the speed as 120 × 2 = 60 miles per hour (ca. 97 km/h).

Ampacity can be calculated by dividing the Wattage by the rated voltage.

What is the ampacity of each conductor?

The highest continuous current that a conductor may carry under normal use settings without going above its temperature rating is known as ampacity. The unit of measurement for current is one amp. To avoid the wire overheating, you must choose the proper size wire for the circuit's current (load) requirements.

Divide the Wattage by the rated voltage to get the ampacity. The predicted Amperage of the circuit is the quotient. Many times, a circuit's particular application correction factors (as mentioned above) will make ampacity necessary.

If force F keeps the object in equilibrium

Answer:

See below

Explanation:

Find the x components of all of the forces shown, add them together, the x-component of the force F will be exactly opposite ( same magnitude but 180 degrees different)

30 cos 55  +     40 cos 205   +   50 cos 320  =  19.26    <====x component sum of all of the forces shown

F  (the x component of ) will be   Either    - 19.26   At zero degrees

4m is the distance moved by the object if 8 rev/s 36. A force of 10N, acting continuously, increases the kinetic energy of an object from 20J to 60J.

The increase in kinetic energy of an object is given by the formula ΔK = \((1/2)mv²\), where ΔK is the change in kinetic energy, m is the mass of the object and v is its velocity. Since the force acting on the object is constant, it can be expressed as F = ma, where F is the force, m is the mass and a is the acceleration.

The work done by the force is given by the formula W = Fd, where W is the work done, d is the distance moved by the object and F is the force.

Using the given information, we can set up the following equations:

\(ΔK = (1/2)mv²f - (1/2)mv²i\)

\(= (1/2)m(vf² - vi²)\)

= 40 J

F = ma

W = Fd

Since the force is acting continuously, we can use the equation W = ΔK to find the distance moved by the object. Substituting the given values into this equation, we get:

W = ΔK

10d = 40

d = 4 m

Therefore, the distance moved by the object is 4m. Option (c) is the correct answer.

Gravitational force between two objects is given by the equation

\(F = G \dfrac{m_1m_2}{r^2}\)

where

\(G =\)universal gravitational constant
\(m_1\), \(;m_2\) are the masses of the objects

\(r\) = distance between the objects

We are given that F = 18 units.

If m₁ is tripled and r is also tripled then

new F = F':

\(F' = G \dfrac{3m_1 \cdot m_2}{(3r)^2}\\\\\\F' = G \dfrac{3m_1 \cdot m_2}{9r^{2}}\\\\\\So \dfrac{F'}{F} = G \dfrac{3m_1 \cdot m_2}{9r^{2}} \div G \dfrac{m_1 \cdot m_2}{r^{2}}\)

\(= \dfrac{3}{9} = \dfrac{1}{3}\\\)

Therefore the new F is 1/3 of the old f

In this case that would be 18/3 = 6 units

The internal energy of an ideal gas at constant temperature remains constant.

As a result, the temperature of an ideal gas directly affects its internal energy. T is the temperature in kelvin and R is the ideal gas constant in joules per mole kelvin (J/mol-K). It is impossible to directly quantify the internal energy of systems that are more complicated than a perfect gas.

An ideal gas's internal energy fluctuates proportionally to its temperature, therefore if its temperature changes, so does the gas's internal energy. Internal energy won't change if the temperature doesn't change.

360 degrees is one full rotation starting at zero

it take 2 s  to the flag to rotate once in a full circle  with 3 rad/s of angular velocity.

Angular velocity is "rate of change of angular displacement with respect to time". i.e. ω= dθ/dt. it is also defined as angular displacement over time. i.e. ω = angular displacement/Time.

Angular velocity shows how much angle can be covered in unit time. It's SI unit rad/s.

Angular acceleration is rate of change of Angular velocity with respect to time.

i.e. α = dω/dt if an object changes its angular velocity in short time, we can say that it has greater angular acceleration. It is expressed in rad/s².

In this problem we have to calculate time, but the angular velocity id not given.

Consider the angular velocity is 3 rad/s.

Given,

Angular displacement θ = 2π

angular velocity ω = 3 rad/s

Time t = ?

Time = θ/ω

Time = 2π/3 rad/s = 2 s
