Vc = A
Part B
Just after the circuit is completed, what is the voltage drop across the resistor?
Vr = _V
Part C
Just after the circuit is completed, what is the charge on the capacitor?

Answers

Answer 1

We can use the equation for the voltage across a capacitor in a charging circuit:

Vc = ε(1 - e^(-t/RC))

where ε is the emf of the source, R is the resistance, C is the capacitance, and t is the time.

a) Just after the circuit is completed, the capacitor is uncharged and acts like a wire. Therefore, the voltage drop across the capacitor is initially 0 V.

Vc = 0 V

b) The voltage drop across the resistor can be found using Ohm's law:

Vr = IR

where I is the current in the circuit.

The current in the circuit can be found using Kirchhoff's loop rule:

ε - IR - Vc = 0

Rearranging, we get:

I = ε/R - Vc/R

At t = 0, Vc = 0, so:

I = ε/R

I = (502 V)/(4700 Ω) = 0.1068 A

Therefore, the voltage drop across the resistor is:

Vr = IR = (0.1068 A)(4700 Ω) = 502 V

c) The charge on the capacitor can be found using the equation:

Q = CVc

At t = 0, Vc = 0, so the initial charge on the capacitor is 0 C.

Which color of flames would represent the HOTTEST temperature emitted from a star? Red Yellow Orange Blue

Answers

The color of flames that represents the hottest temperature emitted from a star is (d) Blue.

Blue flames are associated with the highest temperatures. In the context of stars, the color of a star's light is related to its surface temperature. The hottest stars, such as blue supergiants or blue-white stars, emit a significant amount of blue light due to their high temperatures.

As the temperature decreases, stars emit light in different colors, progressing from blue to white, yellow, orange, and finally red, with cooler stars emitting predominantly red light.

Therefore, if we consider the color of flames as an analogy, blue flames would correspond to the hottest temperature emitted from a star.

A drag racer starts her car from rest and accelerates at 10.0 m/s2 for the entire distance of 400 m .how long did it take the race car to travel this distance in s? answer key

Answers

To travel a distance of 400 m the car will take a time of: 8.944 s

The formulas and procedures we will use to solve this exercise are:

vf = √ (vi² + 2 * a * x)t = (2 * x)/ (vi + vf)

Where:

vf = final velocityx = distancet = timevi = initial velocitya = acceleration

Information about the problem:

vi = 0 m/sa = 10.0 m/s²x = 400 mvf =?t = ?

Applying the final velocity formula we have:

vf = √ (vi² + 2 * a * x)

vf = √ ((0 m/s)² + 2 * 10.0 m/s² * 400 m)

vf = √ (0 m²/s² + 8000 m²/s²)

vf = √(8000 m²/s²)

vf = 89.44 m/s

Applying the time formula we have:

t = (2 * x)/ (vi + vf)

t = (2 * 400 m)/ (0 m/s + 89.44 m/s)

t = 800 m / 89.44 m/s

t = 8.944 s

Explanation:

Explain how a force of 30 N causes an object to rotate pi rad, but another force of 30 N using the same lever arm can cause the object to rotate (2/3) pi rad.

Answers

The difference in rotational displacement caused by two forces of 30 N with the same lever arm can be attributed to the varying moments of inertia of the object.

The rotational displacement of an object depends on the applied force and the object's moment of inertia. The moment of inertia represents the object's resistance to rotational motion and depends on its mass distribution. In the given scenario, the force of 30 N causes the object to rotate pi radians, while another force of 30 N with the same lever arm causes a rotation of (2/3) pi radians. This difference in rotation can be explained by the fact that the moments of inertia of the object are different in the two cases. The object's moment of inertia influences how it responds to rotational forces, and objects with different mass distributions can have different moments of inertia. Therefore, even with the same applied force and lever arm, the resulting rotational displacement can vary based on the object's moment of inertia.

The phrase "like dissolves like" can be described as the compounds which have similar nature dissolve in each other that is polar dissolves polar and non-polar dissolves non-polar molecules.

What is Polarity?

Polarity is the separation of electric charge which is leading to a molecule or the chemical groups which are having an electric dipole moment, with a negatively charged end and a positively charged end as well. Polar molecules are the molecules which must contain one or more polar bonds which occur due to a difference in the electronegativities between the bonded atoms of the molecule.

A simple way to predict the compounds which will dissolve in other compounds is the phrase of the compound such as "like dissolves like". This means that the polar compounds dissolve in polar compounds, and the nonpolar compounds dissolve in nonpolar compounds, however, the polar and nonpolar molecules do not dissolve in each other.

thorium isotope (Th^232) has a half-life of 1.4*10¹⁰ years.
a)write the radioactive decay equation.
b) find the radioactive radiation activity of 10 g of thorium
c)and the activity after 10 years

Answers

The radioactive decay equation for thorium-232 is $Th^{232} - > Ra^{228} + He^{4}$. To find the radioactive radiation activity of 10 g of thorium, calculate the number of nuclei using Avogadro's number and the decay constant. For the activity after 10 years, use the radioactive decay law with the appropriate values.

a) The radioactive decay equation for thorium-232 ($Th^{232}$) can be written as follows:

$Th^{232} - > Ra^{228} + He^{4}$

In this equation, thorium-232 undergoes alpha decay, transforming into radium-228 and emitting an alpha particle (helium-4 nucleus).

b) To find the radioactive radiation activity of 10 g of thorium, we need to calculate the number of thorium-232 nuclei in the given sample. First, we find the number of moles of thorium-232 by dividing the mass of the sample by its molar mass. The molar mass of thorium-232 is approximately 232 g/mol. Thus, the number of moles is:

Number of moles = 10 g / 232 g/mol

Next, we calculate the number of thorium-232 nuclei using Avogadro's number, which is approximately 6.022 × $10^{23}$ nuclei/mol:

Number of nuclei = Number of moles × Avogadro's number

Finally, we determine the radioactive radiation activity (A) by multiplying the number of nuclei by the decay constant (λ). The decay constant (λ) is related to the half-life (T1/2) of thorium-232 through the equation:

λ = ln(2) / T1/2

The decay constant represents the probability of decay per unit time. Therefore, the activity can be calculated as:

Activity = λ × Number of nuclei

c) To find the activity after 10 years, we use the radioactive decay law, which states that the activity of a radioactive substance decreases exponentially with time. The remaining activity (A_t) after a given time (t) is given by the equation:

$A_t = A_0 * (1/2)^{t/T1/2}$

Where A_0 is the initial activity at t = 0. Substituting the initial activity calculated in part b, the decay constant, and the desired time of 10 years, we can determine the activity after 10 years.

In summary, the radioactive decay equation for thorium-232 is $Th^{232} - > Ra^{228} + He^{4}$ . To find the radioactive radiation activity of 10 g of thorium, calculate the number of nuclei and multiply it by the decay constant. For the activity after 10 years, use the radioactive decay law and substitute the appropriate values.

A yellow X on an overhead signal above your lane indicates c) the lane will be closed farther ahead. A yellow X on an overhead signal above your lane is a warning that the lane will be closed ahead, and you should be prepared to merge into another lane.

An overhead signal with a yellow X above your lane is used to indicate that the lane will be closed farther ahead. This signal is usually used in work zones or construction areas to warn drivers of an upcoming lane closure or traffic shift.

The purpose of the yellow X signal is to provide drivers with advanced warning so that they can begin to merge or change lanes safely and smoothly. Drivers should be prepared to merge into another lane or follow the instructions of any flaggers or traffic control devices as they approach the work zone.

It's important for drivers to pay attention to all traffic signals and signs, especially in work zones where conditions can change quickly and unexpectedly. Failing to obey these signals can lead to accidents, injuries, or traffic delays.
