The heart and the circulatory system

The voltage across an inductor ' L ' is

V = L · dI/dt .

I(t) = I(max) sin(ωt)

dI/dt = I(max) ω cos(ωt)

V = L · ω · I(max) cos(ωt)

L = 1.34 x 10⁻² H

ω = 2π · 60 = 377 /sec

I(max) = 4.80 A

V = L · ω · I(max) cos(ωt)

V = (1.34 x 10⁻² H) · (377 / sec) · (4.8 A) · cos(377 t)

V = 24.25 cos(377 t)

V is an AC voltage with peak value of 24.25 volts and frequency = 60 Hz.

8. Picture B

Explanation:

There are 3 states of matter:

- Solid: in solids, atoms/molecules are bond together, so they are not free to move, they can just vibrate around their fixed positions. In solids, atoms/molecules are close and packed with each other

- Liquid: in liquids, atoms/molecules can move past each other, however there are still intermolecular forces that keep them close to each other

- Gas: in gases, atoms/molecules are totally free to move far from each other

In this case, atoms in the gas of a neon sign are represented by picture B, since there the atoms are very far from each other and free to move.

9. Picture C.

Explanation:

the picture that best represents a rock is picture C: in fact, we see that in picture C atoms are packed and close to each other, since it is a solid and atoms are bond to each other. So, picture C represents a solid, therefore it is the picture that best represents a rock.

12: Helium

Explanation:

In the picture:

- Red particles correspond to protons (because they are in the nucleus and they are positively charged)

- Green particles correspond to neutrons (because they are in the nucleus and they are uncharged)

- Yellow particles correspond to electrons (because they orbit the nucleus and they are negatively charged)

This atom as 2 protons and 2 electrons. This means it corresponds to the 2nd element in the periodic table (atomic number = 2), so it corresponds to helium.

13:  Electrons should be arranged in 3 separate orbitals: 2 electrons in an orbital closer to the nucleus, another 2 in a second orbital, and the remaining 3 in the last orbital

Explanation:

The electron configuration for nitrogen is:

[tex]1s^2 2s^2 2p^3[/tex]

which means:

[tex]1s^2[/tex] --> the closest orbital to the nucleus, energy level = 1, orbital s, containing 2 electrons

[tex]2 s^2[/tex] --> second closest orbital to the nucleus, energy level = 2, orbital s, containing 2 electrons

[tex]2p^3[/tex] --> third closest orbital to the nucleus, energy level = 3, orbital p, containing 3 electrons

A) 0

because all of the forces cancel out, so it is not moving with balanced forces.

Answer:

0 Newtons

Explanation:

As you can see in the image all of the forces that are contrary or opposite to one another have the same magnitude, that makes them cancel out, in order for an object to move the force applied most be greater than the force that is setting it at rest, usually the friction, unless one of this forces si greater than the other the object won´t move, so the net force acting on the object will be 0,

See this suggested solution.

1. Let a force F' is the vector sum of the forces P and Q, then it is shown on the attached picture and marked with red color.

2. according to the condition the force F holds the object, then F should have the same length as the force F' and the opposite direction.

3. using the conditions described in 2. the answer is C.

TLDR: R=30 Ohms, I=2 Amps, 12V, 28V, 20V, respectively.

Alright, let’s break this down. There are three resistors in this circuit, meaning that we have to find the equivalent resistance. Luckily, they are all in parallel with one another; this means we can add the resistances together without having to do inverses like in a series problem. This means that the equivalent resistance, Req, would equal:

Req=R1 + R2 + R3

Req=6 + 14+ 10

Req=30 Ohms

This means that we could theoretically replace all three resistors with a 30 Ohm resistor and accomplish the same goal. Now, the entire voltage of the system would normally be reduced to zero after passing through the resistors - in this case, the 60 Vs would be lost after passing through 30 Ohms. This means we’re losing 2V/Ohm; now we can figure out how much we’re losing at each resistor.

By losing 2V per Ohm, we’re losing 12 V at the first resistor, 28 V at the second resistor, and 20 V at the third resistor.

Finally, we can calculate the current through the circuit; for a series circuit, the current remains the same. Using V=IR, we can find that:

V=IR

60 V = I(30 Ohms)

I = 2 Amps

The current passing through the circuit is 2 Amps.

Answer:

A is correct

Explanation:

Answer:

b. 4

Explanation:

The electric force between two charged objects is given by:

[tex]F=k\frac{q_1 q_2}{r^2}[/tex]

where

k is the Coulomb's constant

q1 and q2 are the charges of the two objects

r is the separation between the two objects

In this problem, we have that the charge of one object is quadrupled:

[tex]q_1'=4q_1[/tex]

while all the rest remain unchanged. So the new electric force between the two objects is

[tex]F'=k\frac{q_1' q_2}{r^2}=k\frac{(4q_1) q_2}{r^2}=4 k\frac{q_1 q_2}{r^2}=4F[/tex]

So, the force will quadruple as well.

Answer:

B

Explanation:

Answer: a

Explanation:

The following combination is not feasible to be in equilibrium : 10,10,10

The correct option is A.

A state in which opposing forces or influences are balanced is called equilibrium.

The addition of two smaller forces must be greater than the third force in case of three forces to be in equilibrium.

For A: 10 + 10 >10 or 20 > 10

For B: 10 +5 <17 or 15 <17

For C: 5 +10 > 12 or 15 >12

For D: 5 +12 >13 or 17 >13

So, the gap between the magnitude of balancing forces is very high in (10,10,10).

Thus, the correct option is A.

Answer:

[tex]1.9 kg/m^3[/tex]

Explanation:

The density of an object is given by

[tex]d=\frac{m}{V}[/tex]

where

m is the mass of the object

V is its volume

In this problem,

m = 42 kg

V = 22 m^3

Substituting into the equation, we find the object's density:

[tex]d=\frac{42 kg}{22 m^3}=1.9 kg/m^3[/tex]

33.33 miles/hr

Average speed is the ratio of the total distance covered to time

That is; Speed = distance/time

In this case;

Distance = 100 miles and time =3 hours

                        = 100 miles/3 hours

                        = 33.33 miles/hr

The faster the particles are moving, the more energy they have. Temperature is the average amount of energy of motion of each particle of a substance. That is, temperature is a measure of how hot or cold a substance is. In contrast, the total energy of motion in the particles of a substance is called thermal energy.

The total energy of all the particles in a substance is called the internal energy (U) or symbolized as E. It is the sum of the kinetic energies and potential energies of the system's constituent particles.

The total energy of all the particles within a substance is referred to as the internal energy, often denoted as U or E. This internal energy encompasses both kinetic and potential energy, and it plays a crucial role in understanding the behavior and properties of substances.

1. Kinetic Energy: This component of internal energy is attributed to the motion of the particles within the substance. It includes various forms of motion, such as translational (linear motion), vibrational (vibrational motion of atoms or molecules within a structure), and rotational (rotational motion of molecules). The kinetic energy is directly related to the temperature of the substance, as an increase in temperature leads to higher kinetic energy of the particles.

2. Potential Energy: The potential energy component arises from the relative positions of particles within the substance, their interactions, and the conditions of the system. This can encompass various forms of potential energy, such as chemical potential energy (related to chemical bonds and reactions) and intermolecular potential energy (associated with attractive and repulsive forces between particles). Changes in potential energy can result from changes in the arrangement or composition of particles.

Together, these components contribute to the overall internal energy of the system, influencing its thermodynamic properties and behavior. Understanding the interplay between kinetic and potential energy is fundamental in fields like thermodynamics and chemistry, as it helps elucidate the physical and chemical transformations of substances.

Descabezado Grande is a composite volcano primarily composed of intermediate andesite lava.

The volcano Descabezado Grande is characterized by a composite of various eruption styles, including low viscosity mafic magma and higher viscosity felsic lava, but it is most commonly composed of intermediate andesite lava. This composition places it within the category of composite volcanoes, also known as stratovolcanoes, which feature steep sides and are made of alternating layers of pyroclastic materials and lava flows. The composition of the magma is crucial for determining the volcano's eruptive behavior and landform shape, with intermediate magmas having properties that are in between those of mafic and felsic magmas. Descabezado Grande's magma, being primarily intermediate, indicates a mix of characteristics that contribute to its explosive eruption style and the formation of steep slopes.

If an experiment is replicsble it means that anybody can repeat the experiment and get the same results. It is important that experiments be replicable because if someone else can't repeat what you did, you might have made a mistake. Peer review is what scientists use.

hope this helps

A replicable experiment can be repeated under the same conditions to provide similar results. This is crucial in the scientific method as it ensures reliability of results, allows for verification of the findings, and helps weed out false claims. The inability to replicate an experiment often leads to questioning the credibility of the initial study.

When an experiment is replicable, it means the experiment can be repeated by others under the same conditions and produce the same or very similar results. This ability to reproduce results is one of the essential features of the scientific method, which is used in various fields of academic research, including physics, chemistry, biology, and psychology.

Replicability is essential for several reasons. First, it ensures the reliability of results. Results that are repeated in independent replications are considered more reliable because they have been tested and verified multiple times. Second, replication allows other researchers to check for any mistakes in the original study. Third, successful replications of research provide more evidence to support the original findings, leading to a wider acceptance of the results within the scientific community.

Conversely, if subsequent studies cannot replicate the findings, it may call the credibility of the original research into question.

Through this rigorous process of repeated testing, scientific knowledge advances as false claims are weeded out and factual information is reinforced.
