(A)    conduction implies that the objects are in contact

Answer:    Answer: The object moves forward at 5 m/s, stops, and then changes velocity.

Explanation:

With the information given in the question we can graph the points (image attached).

As we can observe, in the first segment of the graph the velocity is increasing linearly (at a constant rate) and is 5 m/s, then in the second segment we can see the position of the object remains the same from second 2 to second 4, which means the object is stopped.

Finally, in the third and last segment, we can observe a change in velocity (at a negative constant rate, because is decreasing), which is decreasing until the object stops.

Almost every font has four common stylistic sets, besides its regular display. These stylistic sets are alternate characters, ligatures, swashes, and small caps.

Alternate characters are different versions of the same letter, number, or symbol, which can give a font a unique and personalized look. Ligatures are two or more characters that are combined into one glyph to improve the font's legibility and aesthetics. Swashes are decorative elements that extend from letters, adding elegance and flair to a font. Lastly, small caps are lowercase letters that are designed to be the same height as uppercase letters, creating a more consistent and professional look. These stylistic sets can be accessed in many design software programs, allowing designers to customize their typography and create unique and visually appealing designs. Besides its regular display, almost every font has four common stylistic sets. These sets typically include regular, bold, italic, and bold italic styles.

Answer:

Salt crystals are hard and brittle because they are made up of atoms that combine by ionic bonding.

Explanation:

The magnitude of the external magnetic flux through the wire loop decreases, and there is a counterclockwise current induced in the loop (as seen from the left).The correct answer is B, B.

When the switch on the electromagnet is closed, the magnetic field is generated. The magnetic flux passes through the loop, producing an emf and a current in the wire.The direction of the current induced in the wire can be found by Lenz's law, which states that the direction of the induced current will always be in such a way that it opposes the change producing it.In this case, the external magnetic flux through the wire loop will decrease because the magnetic field in the coil opposes the magnetic field of the electromagnet, as a result of which the direction of the induced current in the wire will be counterclockwise as seen from the left.When the switch is reopened, the magnetic flux through the wire loop decreases.

As a result of the decrease in the magnetic flux, the emf in the wire loop will be produced, and the direction of the induced current will be counterclockwise as seen from the left.

Answer:

I. Final velocity, V = 10m/s.

II. Distance, S = 10m.

Explanation:

Given the following data:

Acceleration = 5m/s²

Time = 2 seconds

Since the vehicle starts from rest, initial velocity = 0m/s

To find the final velocity, we would use the first equation of motion.

V = U + at

Substituting into the equation, we have

V = 0 + 5*2

V = 0 + 10

V = 10m/s.

Now, to find the distance covered, we would use the second equation of motion.

S = ut + ½at²

S = 0*2 + ½*5*2²

S = ½*5*4

S = 20/2

S = 10m

The magnitude of the buoyant force on the ball is 30.2 N.

This can be calculated using Archimedes' principle, which states that the buoyant force on an object submerged in a fluid is equal to the weight of the fluid displaced by the object.

The volume of the ball submerged in water is 5.31% of its total volume, which is equal to 0.0531 * 0.61 m³ = 0.032491 m³.

The weight of this volume of water can be calculated by multiplying it by the density of water, which is 1.00 x 10³ kg/m³.

Therefore, the weight of the water displaced is 0.032491 m³ * 1.00 x 10³ kg/m³ * 9.8 m/s² = 317.6 N.

Since the buoyant force is equal to the weight of the displaced water, the magnitude of the buoyant force on the ball is 317.6 N.

However, since the ball is floating, the buoyant force is balanced by the weight of the ball, so the actual magnitude of the buoyant force is equal to the weight of the ball, which is 30.2 N.

Answer:

The car moving with speed 50 mph

Explanation:

We are given that

Distance, s=280 feet=85.3 m

1 feet=0.3048 m

Coefficient of kinetic friction=\(\mu_s=0.3\)

1 m/s=2.237 mph

We have to find the speed of car moving.

Speed, v=\(\sqrt{2\mu_s gs}\)

Where \(g=9.8ms^{-2}\)

Using the formula

Speed of the car,v=\(\sqrt{2\times 0.3\times 9.8\times 85.3}\)

Speed of the car,v=22.4 m/s

Speed of the car, v=\(22.4\times 2.237\approx 50 mph\)

Hence, the car moving with speed 50 mph

Measuring tool that the student should have used in order to verify the conservation of momentum is force sensor.

To verify the conservation of momentum for closed two-cart system,  student should use force sensor to measure the forces acting on carts during the collision. Force sensor can provide a quantitative measurement of forces that each cart exerts on other cart which can help to determine if momentum is conserved.

By measuring forces,  student can calculate the impulse of each cart during collision. The impulse can then be used to calculate change in momentum of each cart, and if total momentum before the collision is equal to total momentum after collision, then momentum is conserved.

The T-s diagram for the cycle will show the refrigerant entering the turbine as a saturated vapor at 1.4 MPa, expanding isentropically to 0.7 MPa, and then being condensed at constant pressure in the condenser. The refrigerant is then compressed at constant pressure back to its initial state.

The thermal efficiency of the cycle can be calculated using the formula for thermal efficiency, which is the net work output divided by the heat input.

Capillary walls consist of endothelial cells, supported on a cellular matrix called basement membrane.

Endothelial cells form the inner lining of capillary walls. They are specialized cells that create a thin, semipermeable barrier allowing for the exchange of nutrients, gases, and waste products between the blood and surrounding tissues. These cells are flat and arranged in a single layer, providing a large surface area for efficient exchange.

The endothelial cells are supported by a basement membrane, which is a thin, fibrous matrix made up of proteins such as collagen and laminin. The basement membrane provides structural support to the capillary walls and helps maintain their integrity. It acts as a filter, regulating the passage of substances based on their size and charge.

Together, the endothelial cells and the basement membrane play a crucial role in the function of capillaries, facilitating the exchange of substances between the bloodstream and the surrounding tissues.

Answer:

chemical potential energy

Explanation:

When the sun's radiant energy falls on Earth's oceans, it causes water to change state by evaporating. The form of energy water vapor have is chemical potential energy. when heat energy of sun falls on water surface, its state change from liquid to gas. This gas rises above in the form of water vapor. Its a chemical change. If this vapor get condense/ cool, it will turn into liquid again. We can say that vapor has potential to transform into water again. Thus, the energy stored in water vapor is called chemical potential energy.

A network of nerves known as the sympathetic nervous system aids in the body's "fight-or-flight" reaction. When you're under stress, in danger, or engaged in physical exercise, this system becomes more active.

increases in heart rate, blood pressure, breathing rate, and pupil size are caused by this area of the neurological system. Additionally, it results in blood vessels narrowing and a decrease in digestive juices.

The sympathetic nervous system is a portion of the nervous system that is responsible for producing reflex cardiovascular system alterations as well as localized adjustments (such sweating in reaction to a rise in body temperature).

Along with its opposite, the parasympathetic nervous system, the sympathetic nervous system is a component of the autonomic nervous system. The thoracic and lumbar spinal cord segments, collectively referred to as the thoracolumbar division, are where the sympathetic nervous system originates (T1 to L2,3).
