In the alpha decay of Francium-221, what daughter element is produced? (You may need to refer to the periodic table in the lesson.)

Answers

In an alpha decay, the original nucleus decays into a daughter nucleus + an alpha particle, which consists of 2 protons and 2 neutrons.
The atomic number (number of protons) of the Francium is 87, and since in the decay it loses 2 protons, the atomic number of the daughter nucleus should be 85. Looking at the periodic table ,this corresponds to Astatine, and therefore this is the element produced in the alpha decay of Francium-221.
Moreover, the mass number (number of protons+neutrons) decreases by 4 (because an alpha particle carries 2 protons+2 neutrons), therefore in the reaction the mass number will decrease from 221 to 217.
So, the daughter element is astatine-217.

which statement accurately describes what happens when ice melts in terms of energy

Answers

When the ice melts, it changes from a solid state to a liquid state.

When it is heated, the kinetic energy of the molecules that compose it, increases, the energy that the ice received, is transformed into potential energy and the content of kinetic energy stays constant. This causes a variation in the order of the ice molecules, which have a fixed position when the matter is in solid state.

In terms of energy the ice absorbs energy causing the molecules of water to have more kinetic and potential energy, changing their configuration from a solid to a liquid.

how to find current in a series circuit

Answers

Divide the battery voltage by the sum of all the resistances in the series circuit. The quotient is the circuit current, in Amperes.

Answer: To find the current in a series circuit, you can follow these steps:

1. Identify the values of the resistors in the circuit. These values are usually given in ohms (Ω) and can be labeled with different letters or numbers.

2. Calculate the total resistance (R) of the circuit by summing the individual resistances. For a series circuit, the total resistance is simply the sum of all the resistances.

Explanation:

Example: If you have three resistors with values R1 = 10 Ω, R2 = 20 Ω, and R3 = 30 Ω, the total resistance (R) would be R = R1 + R2 + R3 = 10 Ω + 20 Ω + 30 Ω = 60 Ω.

3. Determine the total voltage (V) across the circuit. The total voltage is usually given and can be labeled as V or E.

4. Use Ohm's Law, which states that the current (I) flowing through a circuit is equal to the voltage (V) divided by the resistance (R). Mathematically, it can be expressed as I = V / R.

Example: If the total voltage (V) across the circuit is 120 volts and the total resistance (R) is 60 Ω, the current (I) flowing through the circuit would be I = V / R = 120 volts / 60 Ω = 2 amps.

So, in this example, the current in the series circuit is 2 amps. Remember to always include the appropriate units (A for amps) in your final answer.

It's important to note that in a series circuit, the current remains the same at all points in the circuit. So the value you find for the current is the same for every resistor in the circuit.

The power of imagination helps a scientist to propose valid scientific explanations about the solar system use biased methods to answer questions about the solar system pose questions about the solar system which are not reasonable create theories about the solar system which are not acceptable

Answers

The first option is the correct answer - The power of imagination helps a scientist to propose valid scientific explanations about the solar system. As the option implies, what the scientist gets by imagination is simply a proposition (scientifically called an hypothesis), since there is limited evidence. The scientist's imaginations, and the propositions thereof, is the starting point for further investigation that yields valid scientific theories.

The power of imagination is integral to proposing scientific theories, particularly in the study of the solar system; however, these theories must be tested against experimental data to be accepted. Kepler's imaginative approach led to the formulation of laws that underpin our understanding of planetary motion, highlighting the scientific method's reliance on creativity tempered by empirical validation.

The power of imagination plays a crucial role in the scientific method, especially when it comes to understanding the solar system. Scientists use their creativity to construct theoretical models of how the universe could function and then perform experiments to see which models hold. For example, the work of Johann Kepler, who proposed the laws of planetary motion, showcases how imaginative concepts can lead to significant scientific advancements. While Kepler's models were initially based on mystical ideas, they eventually contributed to our modern understanding of celestial dynamics. Thus, the imaginative component of science allows for the proposal of new and sometimes revolutionary theories, but ultimately, it's through experimentation and data that these theories are validated or refuted.

Science thrives on new ideas and is always ready to assess the validity of different models and theories through careful experimentation. As new data come to light, scientists continuously refine their theories to reflect the most accurate understanding of the natural world. This process illustrates the dynamic and adaptive nature of scientific inquiry, which values empirical evidence overall.

Find the angle formed by two forces of 7N and 15N respectively if its result is worth 20N

Answers

First, you need to make certain assumptions before solving this question. Why? Because there are no information given about the direction of these forces. In such questions as above, ALWAYS make the following assumptions:

1) Take first force, say [tex]F_{1}[/tex], and assume that it is pointing towards the x-direction.

Let us take the 7N force! By keeping the above assumption in our minds, the force vector would be like:
[tex]F_{1}[/tex] = [tex]7i[/tex], where [tex]i[/tex] = Unit vector in the x-direction.

2) Take the second force, say [tex]F_{2}[/tex], and assume that it is making an angle [tex] \alpha [/tex] with the first force [tex]F_{1}[/tex].

Let us take the 15N force! By keeping the above assumption in our minds, the forces vector would be like:

[tex]F_{2} = (15*cos \alpha)i + (15*sin \alpha )j[/tex]

Now from simple vector addition, we know that,
[tex]F_{R} = F_{1} + F_{2}[/tex] --- (A)

Where [tex]F_{R}[/tex] = Resultant vector.
NOTE: In equation (A), all forces are in vector notation. Assume that there is an arrow head on top of them.

Let us find [tex]F_{1}+F_{2}[/tex] first!
[tex]F_{1}+F_{2}[/tex] =  [tex]7i+(15*cos \alpha)i + (15*sin \alpha )j[/tex]

=> [tex]F_{1}+F_{2}[/tex] =  [tex](7+15*cos \alpha)i + (15*sin \alpha )j[/tex]

Now the magnitude of [tex]F_{1}+F_{2}[/tex] is,
| [tex]F_{1}+F_{2}[/tex]| = [tex] \sqrt{ (7+ 15*cos \alpha)^{2} + (15*sin \alpha )^{2}}[/tex]

=> | [tex]F_{1}+F_{2}[/tex]| = [tex]\sqrt{ 49 + 225*(cos \alpha)^{2} + 210*(cos \alpha)+ 255*(sin \alpha )^{2}}[/tex]

Since [tex](sin \alpha)^{2} + (cos \alpha)^{2} = 1[/tex], therefore,

=> | [tex]F_{1}+F_{2}[/tex]| = [tex]\sqrt{ 49 + 225 + 210*(cos \alpha)}[/tex]

Since  | [tex]F_{1}+F_{2}[/tex]| = |[tex]F_{R}[/tex]|, and the magnitude of the resultant force is 20N, therefore,

|[tex]F_{R}[/tex]| = | [tex]F_{1}+F_{2}[/tex]|
20 = [tex]\sqrt{ 49 + 225 + 210*(cos \alpha)}[/tex]

Take square on both sides,
400 = [tex] 49 + 225 + 210*(cos \alpha)[/tex]
[tex](cos \alpha) = \frac{3}{5} [/tex]

[tex] \alpha = 53.13^{o}[/tex]

Ans: Angle formed by the two forces, 7N and 15N, is: 53.13°

What is the frequency of a clock waveform whose period is 750 microseconds?

Answers

use this formula to find your answer...

Determine the frequency of a clock waveform whose period is 2us or (micro) and 0.75ms

frequency (f)=1/( Time period).

Frequency of 2 us clock =1/2*10^-6 =10^6/2 =500000Hz =500 kHz.

Frequency of 0..75ms clock =1/0.75*10^-3 =10^3/0.75 =1333.33Hz =1.33kHz.

The frequency of a clock waveform whose period is 750 microseconds would be 1333.33 Hertz because the frequency is the reciprocal of the time period of the waveform.

What is the frequency?

It can be defined as the number of cycles completed per second. It is represented in hertz and inversely proportional to the wavelength.

frequency of the waveform = 1 /time period of the waveform

As given in the problem we have to find the frequency of a clock waveform whose period is 750 microseconds,

Then the number of cycles per second is known as the frequency

f = 1 /( 750 ×10⁻⁶)

f =1333.33 Hertz

Thus, the frequency of a clock waveform would be 1333.33 Hertz.

Answers

The Answer Is D Because When Uu Magnify Large Items The Image Is Reflected Back To The Magnifying Glass Which Makes The Image Appear In The Back

Option (D) is correct. The virtual image is always firmed in front of the lens or on the same side of the lens as of the object.

Explanation:

The image formed by the lens are categorized in two broad categories.

Real ImagesVirtual Images

The Real Image is a image that is formed by the actual meeting of the incoming rays from the object. The real image is an image that can be obtained on the screen.

The Virtual Image is an image that is formed by the the imaginary meeting of the incoming rays from the object. The virtual image cannot be obtained on the screen.

Since the real image is formed by the actual meeting of the rays, the rays would meet on the other side of the lens as that of the object. It means that a real image is formed behind the lens whereas for a virtual image, the diverging rays from object are extended in backward direction and made to meet on the same size as that of the object.

Thus, Option (D) is correct. The virtual image is always firmed in front of the lens or on the same side of the lens as of the object.

Use the graph to fill in the missing temperature, salinity, and density values on the table.

Answers

Answer:

Positon      value to fill in

A              1.025 g/cm^3

B               34%

C               15°C

Explanation:

1) The first value to fill in is the density on position A.

The procedure is using the temperature given, i.e. 20°C, and the salinity, 35ppt, with the graph.

Place your ruler on the horizontal axis on the mark of 35% and go upward vertically until reaching the horizontal lecture of 20°C, the intersection points is on the curve of density 1.025 g/cm^3.

So, that is the density to put on the table for the position A: 1.025 g/cm^3.

2) The next value to find is the salinity on position B.

Use the temperature 25°C and the density 1.023.

Move horizontally from the vertical read of 25°C to the right until you reach the curve with 1.023 g/cm^3 density. Then move vertically downward to read the salinity which is 34%.

Fill in the blank of position B that value: 34%.

3) The final blank corresponds to the temperature on the position C.

Moving upward from the salinity 35% until the curve density = 1.026 g/cm^3, you find that the intersection is at temperature 15°C.

That is the value to put on the missing value for position C: 15°C.

photon energy is proportional to which of the following. a. speed of light in a vacuum. B frequency of the light emitting the photon. C intensity of the light emmitting the photon. D wavelegnth of light emmitting thr photon.

Answers

We have that according to the quantum theory from Planck, E=h*f where h is a constant and f is the frequency, thus B is correct. Let's analyze the other choices: The speed of light in vacuum is irrelevant to the energy of the photon. The instensity of a light source is correlated to the amount of photons in that light beam but it does not affect individual photons. Finally, if l is the wavelength of light, l*f=c. Substituting this in the first equation we see that photon energy is inversely proportional to the wavelength.

Which of the following is the best evidence that work has been done on or by an object?

Answers

The answer is A.The energy of the object has changed.

The change in the energy of an object is the best evidence that work has been done on or by an object. Thus, the correct option is A.

What is Work done?

Work is done on an object or by an object whenever a force is applied on the object that moves it over a certain distance or change the energy of the object. This movement is a result of energy change.

We can calculate the energy transferred to an object, or the work done, by simply using the formula where we multiply the force by the distance moved in the direction of the force applied.

Therefore, Energy transferred = work done = force × distance moved in the direction of the force.

W = f × d

A ski lift carries people along a 220-meter cable up the side of a mountain. Riders are lifted a total of 110 meters in elevation. What is the idea mechanical advantage of the ski lift?

Answers

Final answer:

The Ideal Mechanical Advantage (IMA) of the ski lift is 2. It is calculated by dividing the total length of the lift cable by the total change in elevation.

Explanation:

The question is asking about the Ideal Mechanical Advantage (IMA) of a ski lift. The IMA is determined by the ratio of the distance over which the input force is applied to the distance over which the output force is applied.

In the case of a ski lift, the input force is applied over the entire length of the cable, while the output force is applied over the change in elevation. Therefore, the IMA of the ski lift would be the total length of the cable (220 meters) divided by the total change in elevation (110 meters), giving an IMA of 2.
