Momentum is a vector quantity, hence the vector sum of the momenta should be compared. After the collision, the kinetic energy of the system in scenario 1 will be lower than that in scenario 2.
The system's momentum prior to the collision and the system's momentum following the collision should be same in order to demonstrate momentum conservation.

W hat are electronegative gases? Why is the breakdown strength h Marks CO igher in these gases compared to 2 . that in other gases What are anode and cathode streamers?
Electronegative gases are gases that have a higher electron affinity, which means they have a greater tendency to attract and hold onto electrons. Examples of electronegative gases include chlorine, fluoride, and oxygen.
The breakdown strength, or the electrical field strength required to cause electrical breakdown in a gas, is higher in electronegative gases compared to other gases because the electronegative atoms or molecules in these gases can more readily capture free electrons and form negative ions. This reduces the number of free electrons available for conduction, making it more difficult for an electrical breakdown to occur.
Anode streamers are luminous discharges that occur in electrical breakdown in gases and that originate from the anode, or the positively charged electrode. Cathode streamers are similar discharges that originate from the cathode, or the negatively charged electrode. They are caused by the ionization of the gas and the movement of electrons in the electric field. These streamers are responsible for the initiation of the electrical breakdown.

when there is a positive pressure gradient in the horizontal x direction in a fluid, i.e. , and there are no shearing stresses, then how will the fluid move?
When the pipe is completely developed, the pressure gradient Dp/L (the pressure differential between two stations separated by L) is constant and the pressure declines linearly with distance. The pressure gradient likewise rises linearly with flow rate in this area.
Bernoulli's principle may be theoretically understood as the idea that a fluid moving from a high pressure to a low pressure area would accelerate as a result of the net force acting in the direction of motion. To keep the top plate moving at a constant speed U, the system has to be subjected to a shear stress, t = (F/A). This stress has the formula t = m (U/h), where m is the fluid's viscosity and U/h is its strain rate.

When a dielectric is inserted between plates of capacitor stored energy, will it increase or decrease?
When the charge on a capacitor plate increases while it is still connected to the battery, or when a dielectric slab is inserted between the plates, the capacitance (C) increases, the potential difference (V) between the plates stays constant, and the amount of energy stored in the capacitor increases.
Does a capacitor's dielectric improve the amount of energy stored?The dielectric is attracted towards the capacitor's plates by the charges on its surface, so it tends to stay inside the device. The capacitor reduces the quantity of energy retained by lowering the dielectric between the plates.

The concepts come from Sigmund Freud's psychoanalysis, which placed a strong emphasis on the unconscious mind as the root of psychological suffering and dysfunction. A childhood trauma that has since caused this tendency, obsessive hand washing, may be connected. An anxious experience from infancy may be the root of nail biting. A childhood occurrence that made a youngster afraid of being alone in a public place could lead to adult agoraphobia. explanation or interpretation of behavior or mental states in terms of mental or emotional forces or processes.

Signals will get distorted if an op amp is used over its slew rate limit.
How do you figure out an op-output amp's voltage?This is amplifier circuit a 1.5 v peak-to-peak 1 kHz sinusoidal waveform.might represent the output signal, v o (t)
Equations. AV input Equals V out
Op-amp inversion: A = - R2/R1
A = 1 + R2/R1 for non-inverting op-amps.
The input resistance of a perfect op amp is infinite.
Signals will get distorted if an op amp is used over its slew rate limit. The sine wave example provides the clearest illustration of this. At the zero crossing point, voltage changes at their fastest pace.

If an op amp is used at a rate higher than its slew rate limit, signals will become distorted assuming an ideal op-amp. dc power supplies are used to power up the op-amp.
What is an enhancer circuit?A circuit known as an electrical or electronic amplifier generates an output signal that is a larger replica of its input by utilizing an external power supply. A speaker's voice is amplified with an audio amplifier, an easily recognizable application, to make it easier for them to be heard in large spaces.
What purpose does the amplifier circuit serve?In marine automation, control, and other electronic circuits, amplifiers or operational amplifiers (op-amps) are frequently utilized. Typically, a voltage or a current signal serves as the applied input signal. An amplifier's goal is to produce a signal that is larger than the input signal.

1.4-8 a car weighing 130 kn when fully loaded is pulled slowly up a steep inclined track by a steel cable (see figure). the cable has an effective cross-sectional area of 490 mm2, and the angle a of the incline is 308. (a) calculate the tensile stress st in the cable. (b) if the allowable stress in the cable is 150 mpa, what is the maximum acceptable angle of the incline for a fully loaded car?
A steel cable is slowly pulled up a steeply inclining track by a car that weighs 130kN when fully loaded; (b) the maximum allowable incline angle is 30°.
What is a proper angle?The maximum angle of incidence where the medium (typically air) meets the core (n1) is known as the acceptance angle () for an optical fibre. This angle determines how light enters and travels along the optical fibre. The optical fiber's numerical aperture is the sine of the acceptance angle.
The acceptance angle, which is calculated as the acceptance cone's half-angle, serves as a gauge of a fiber's capacity to gather light (the maximum cone of light that can enter or exit the fiber.) Be aware of what follows: The acceptance cone is triangular in shape.
The NA is related to the cutoff angle, which is the maximum acceptance angle (max) (Figure 1). At the intersection of the fiber's core and cladding, rays with an angle of incidence of maximum are totally internally reflected (TIR). These rays continue to be trapped in the core as they travel down the fibre.

Given the tapered bar/axial element below, determine the exact displacement interpolation function and the associated exact shape functions. Show all intermediate steps.
In FEM, nodal displacement is calculated using the matrix equation shown below: [K] is the global stiffness matrix, [u] is the displacement (solution) vector, and [F] is the vector of forces.
Then, they are interpolated using shape functions—basically, polynomials of various orders—over complete elements. Although linear shape functions, such as a straight line used to approximate a distance between two places, are the most fundamental, quadratic shape functions, such as a quadratic curve, are becoming far more prevalent. There are even even higher order shape functions (such as cubic), but they are uncommon in real-world applications. Gauss Points, not nodes, are used to compute an element's stress. You can search up the locations of the GPs for any specific type of element, but let's talk about singles here.

Mars is a planet with a very similar daily cycle to the Earth. Its sidereal day is 24 hours, 37 minutes and 22 seconds, and its solar day 24 hours, 39 minutes and 35 seconds. A Martian day (referred to as “sol”) is therefore approximately 40 minutes longer than a day on Earth.The Earth zips around the Sun at about 67,000 miles per hour, making a full revolution in about 365 days - one year on Earth. Mars is a little slower, and farther from the sun, so a full circuit takes 687 Earth days - or one Mars year.Temperatures on Mars average about -81 degrees F. However, temperatures range from around -220 degrees F. in the wintertime at the poles, to +70 degrees F. over the lower latitudes in the summer.To learn more about vacation refers to:

A full revolution around the Sun takes approximately 365 days, or one year on Earth. The Earth travels around the Sun at about 67,000 miles per hour. A full circuit on Mars takes 687 Earth days, or one Mars year, because Mars moves a little slower and is further from the sun.
