Answer:

d:extrusion

Explanation:

Extrusion has nothing to do with the formation of sedimentary rock, since it is a process of building objects with a defined and fixed cross section. The material is extracted using a die with the cross section to be made. This process allows the creation of complex cross sections with brittle materials, since the material only finds compression and cutting forces.

The correct option is Option A (Electric Field). Among the given options, the electric field is a vector quantity. The other quantities such as electric charge, electric energy, and electric potential difference are all scalars.

Among the given quantities, the electric field is a vector quantity, while the others are scalars. A vector quantity has both magnitude and direction, making it possible to be represented by arrows indicating the direction and strength of the field.

Key differences :

For example, the electric potential of a point charge is given by V = kQ/r, which is a scalar, whereas the electric field is defined as the force per unit charge and is a vector.

Answer:

Velocity of plane = 30.93 m/s

Explanation:

Considering vertical motion of ball

    Initial velocity, u =  0 m/s

   Acceleration , a = 9.81 m/s²

   Displacement, s = 195 m

   We have equation of motion s= ut + 0.5 at²

   Substituting

       s= ut + 0.5 at²

       195 = 0 x t + 0.5 x 9.81 x t²

        t = 6.31 seconds

Now considering horizontal motion of ball

   Acceleration , a = 0 m/s²

   Displacement, s = 195 m

   Time, t = 6.31 s

   We have equation of motion s= ut + 0.5 at²

   Substituting

       s= ut + 0.5 at²

       195 = u x 6.31 + 0.5 x 0 x 6.31²

        u = 30.93 m/s

Velocity of plane is horizontal initial speed of ball = 30.93 m/s

Velocity of plane = 30.93 m/s

During an earthquake or any ground movement, a seismograph would produce an output called seismogram in which we could see the recording of the motion of the ground in the three Cartesian axes (x, y, and z). A seismograph has a special device called seismometer that is extremely sensitive to up and down motions of the earth and this device can be understood by visualizing a weight hanging on a spring.

Since two earthquakes are producing different relative strength, therefore the correct answer to this would be:

“The seismograms produced during the two earthquakes will be very different. The stronger one will have a larger amplitude than the weaker one.”

Final answer:

A seismograph near the San Andreas fault will record larger deflections on the seismogram for a strong earthquake and smaller deflections for a weaker one, due to the higher amplitude of seismic waves. The Richter scale being logarithmic means significant differences in energy release between different magnitudes. Additionally, three-component seismographs enhance earthquake analysis by measuring three-dimensional motion.

Explanation:

A seismograph near the San Andreas fault that detects earthquakes of varying strengths would produce different seismograms for a very strong earthquake and a relatively weak one. The seismograph's recordings, known as seismograms, reflect the earthquake strength through the amplitude of the waves recorded. For a stronger earthquake, the seismic waves will have a greater amplitude, resulting in larger deflections on the seismogram, whereas a weaker earthquake will produce smaller deflections. Additionally, the patterns of P-waves (primary waves) and S-waves (secondary waves) captured by the seismograms are crucial for determining the epicenter of an earthquake by comparing arrival times recorded by multiple seismographs.

Since the Richter scale is logarithmic, the difference in magnitude between two earthquakes is significant, with each whole number increase on the scale representing a tenfold increase in amplitude of the seismic waves and roughly a thirtyfold increase in the released energy. The seismogram produced during a very strong earthquake would show considerably higher amplitudes and longer durations than the seismogram of a weaker earthquake.

Moreover, advanced seismograph stations with three-component seismographs can provide detailed information about the earthquake source by measuring motion in three perpendicular directions (east-west, north-south, and up-down), thereby contributing to a more comprehensive understanding of the earthquake's characteristics.

The metric system is used in science because it is universally adopted, easy to convert, and flexible across large and small numerical ranges. Every unit in the metric system increases by a factor of ten, an advantage not found in the U.S customary units. Metric units are easily scalable across different fields, making it a practical choice in science.

In the realm of science, it is more common to use the metric system, a measurement system adopted by most countries, except the United States. A core advantage of adopting this system is that every unit increases multiplicatively by a factor of ten. The base units of the metric system are the meter for length, kilogram for mass, and second for time.

One significant advantage of such system is its flexibility in scaling across extremely large or small numerical ranges simply through the use of an appropriate metric prefix, making it universal across various scientific and professional fields. For instance, in construction, one would most likely deal with meters, whilst in aviation, kilometers are more suitable, and nanometers find their use in optical design.

Unlike in the system of U.S customary units where conversions between various units might be complicated, the metric system offers simple conversions by merely shifting the decimal place of a number due to the sequential powers of 10 of the metric prefixes.

An inelastic collision, in contrast to an elastic collision, is a collision in which kinetic energy is not conserved due to the action of internal friction. In collisions of macroscopic bodies, some kinetic energy is turned into vibrational energy of the atoms, causing a heating effect, and the bodies are deformed.

Explanation:

Answer:

The result is only as precise as the least precise measurement used in the calculation.

Explanation:

To maintain the constant velocity of a 2-kg object moving horizontally at 4 m/s, no net force is required as per Newton's first law of motion.

The question asks how much net force is required to keep a 2-kg object moving horizontally at a constant speed of 4 m/s. In physics, especially when discussing Newton's laws of motion, if an object is moving at a constant velocity, the net force acting on it is zero. According to Newton's first law of motion (also known as the law of inertia), an object will continue to move at its current velocity unless acted upon by a net external force. Therefore, if the 2-kg object is moving horizontally at a steady speed and is not accelerating, the net force required to maintain that steady motion is 0 Newtons.

Answer:

Cross contamination.

Step-by-Step Explanation:

The contamination that results  from spread of bacteria from meat to vegetable is called cross contamination which means the bacteria from one type of food transferred to  other food which eventually spoil the food.

This happens by direct contact of two types of food.

The contamination that results from the spread of bacteria from meat to vegetables is called Cross-contamination.

Cross-contamination is the movement of bacteria or other pathogenic microbes from one food item or surface to another, which can result in the spread of diseases.

In the case of meat and vegetables, cross-contamination can happen if bacteria from uncooked or carelessly handled meat come into contact with vegetables, either directly or through shared surfaces. This may occur while handling, storing, or preparing food.

Using separate cutting boards and utensils for raw meat and raw vegetables, washing your hands completely after handling raw meat, and storing meat and vegetables separately in the refrigerator are all critical ways to reduce the risk of cross-contamination.

Hence, the contamination that results from the spread of bacteria from meat to vegetables is called cross- contamination.

An example of a non-cyclic process is irreversible processes, which depend on the path and do not return to their original state.

Progression is the classic increase in the fitness of the individual which is essential to achieve fitness goal.

Further Explanation:

Respiratory and circulatory system works together as a coupled unit for delivering oxygen and nutrients to the other part of the body and take away carbon dioxide and waste from the body to support homeostasis. The main purpose of the cardiovascular system is to support the adequate blood flow and supply adequate amount of nutrient to all body tissue and cells and also help in regulating the body temperature.

During physical exercise, the oxygen demand of the muscle tissue increase by 15 to 25 time than normal or rest condition because the more energy is required. A hormone also helps in controlling a number of physiological reactions such as energy formation, reproductive processes, tissue growth and degradation of the muscle protein.

Biomass power plants, geothermal power plants, and nuclear power plants are types of power plants that generate virtually no pollution. Biomass power plants burn organic matter (biomass) from plants to create electricity, while geothermal power plants use the natural heat flow from the Earth's core to generate steam that turns turbines and produces electricity. Nuclear power plants use fission to generate electricity without emitting air pollutants or CO2. However, it is important to note that nuclear power plants produce radioactive waste that needs to be safely stored for an extended period of time.

Answer:

A. 22 Hz and 42 Hz

Explanation:

When two waves of slightly different frequency meet each other, they produce an interference pattern called beat. The frequency of this beat is equal to the absolute value of the difference between the individual frequencies of the two waves:

[tex]f_B=|f_1-f_2|[/tex]

In this problem, we have 20 beats per second, so the beat frequency is

[tex]f_B = \frac{20}{1 s}=20 Hz[/tex]

Therefore, we have to find the pair of waves whose frequency difference is 20 Hz. Let's analyze each choice:

A. [tex]f_B = |22 Hz - 42 Hz|=20 Hz[/tex] --> YES

B. [tex]f_B = |47 Hz - 55 Hz|=8 Hz[/tex] --> NO

C. [tex]f_B = |38 Hz - 63 Hz|=25 Hz[/tex] --> NO

D. [tex]f_B = |18 Hz - 26 Hz|=8 Hz[/tex] --> NO

So, the correct choice is A.

Tarzan's speed at the bottom of the swing can be found using the conservation of energy principle, resulting in approximately 20.76 m/s.

To find Tarzan's speed at the bottom of the swing, we use the principle of conservation of energy. Initially, Tarzan has gravitational potential energy (GPE) when the vine is level. As he swings down, this potential energy is converted into kinetic energy (KE).

At the bottom of the swing, assuming no energy loss to friction or air resistance, all GPE has been converted into KE. The formula for potential energy is U = mgh, where m is mass, g is the acceleration due to gravity, and h is height. The formula for kinetic energy is KE = ½mv², where v is velocity. Setting GPE equal to KE and solving for v gives v = √(2gh).

Substituting the known values, g = 9.8 m/s² and h = 22 m, we get:

v = √(2 × 9.8 m/s² × 22 m) = √(431.2 m²/s²) ≈ 20.76 m/s.

Therefore, Tarzan's speed at the bottom of the swing would be approximately 20.76 m/s.
