Part A

The angular separation of the two stars is 0.03 degrees

Part B

The angular separation of the two stars is 108 arcseconds.

Part C

Yes, the Hubble Space Telescope can resolve the two stars.

Angular separation is the angular distance between two objects as seen from a particular point in space. This is usually expressed in degrees, arcminutes, or arcseconds. It is a measure of the angular separation between two objects, such as stars, planets, galaxies, or other celestial objects, as seen from Earth. The angular separation of two objects is the angle between them as seen from the observer's point of view.

For example, the Moon and the Sun have an angular separation of 0.5 degrees when they are in opposition.

Part A:

To find the angular separation of the two stars, we can use the formula:

θ = arctan(d/D)

where θ is the angular separation, d is the physical distance between the two stars, and D is the distance to the stars from Earth.

Substituting the given values, we get:

θ = arctan(100,000,000 km / (200 x 9.461 trillion km))

θ = arctan(100,000,000 km / 1.8922 x 10^15 km)

θ = 0.03 degrees

Therefore, the angular separation of the two stars is 0.03 degrees.

Part B:

To convert degrees to arcseconds, we can use the formula:

1 degree = 3600 arcseconds

Substituting the value we found in part A, we get:

θ = 0.03 degrees x 3600 arcseconds/degree

θ = 108 arcseconds

Therefore, the angular separation of the two stars is 108 arcseconds.

Part C:

To determine if the Hubble Space Telescope (HST) can resolve the two stars, we need to compare the angular separation of the stars to the angular resolution of the HST. The angular resolution of a telescope is the smallest angle between two point sources that the telescope can distinguish.

The angular resolution of the HST is about 0.05 arcseconds. Since the angular separation of the two stars is 108 arcseconds, the HST can easily resolve the two stars as separate objects.

Therefore, the HST can resolve the two stars in the binary star system.

The answer is closest to option e, 1.97 m/s. To solve this problem, we need to use conservation of energy. The initial potential energy of the system is converted into kinetic energy as the string unwinds.

We can find the potential energy using the equation U = Iω²/2, where I is the moment of inertia of the pulley, and ω is its angular velocity.

The potential energy of the system is given by U = Iω²/2 = (0.0352 kg m²)(ω²)/2. Initially, the potential energy is all stored in the string, so we can set U equal to the work done by the constant force to find the final kinetic energy:

U = Fd = (5.00 N)(2.31 m) = 11.55 J

Equating this to the kinetic energy, we get:

K = U = (0.0352 kg m²)(ω²)/2

Solving for ω, we get:

ω = √(2K/I) = √(2U/I) = √(2(11.55 J)/(0.0352 kg m²)) = 14.44 rad/s

Now we can find the final speed of the string by multiplying the final angular velocity by the radius of the pulley:

v = ωr = (14.44 rad/s)(0.125 m) = 1.805 m/s

Therefore, the answer is closest to option e, 1.97 m/s.

The function is as follows:

f(t)=-10cos(t) + 15

The time in this case is shown as t.

We must change t=/2 in the given function to obtain the runner's speed at t=/2 seconds:

f(π/2) = -10cos(π/2) + 15

Velocity is the pace and velocity of an object's movement, whereas speed is the forecasting at which an objects is travelling along a path. In other words, velocity is a vector, whereas quickness is a scalar value. As a result, the fundamental unit of time and the basic element of distance are combined to form the Special name of speed. Thus, the metre per second (m/s) is the Substrate concentration of speed.

a = 19 and b = 7

Average speed, 54 km = 48+a km/h

Plug a = 19

54 km = 48+19

= 67 km/h

remaining speed

86 km = 43-b km/h

where b = 7

Average speed = 36 km/h

Average speed = total distance / total time taken

For the uniform line of charge, the electric field $E$ is inversely proportional to the distance $r$, so $Er$ should be constant. For the uniformly charged sphere, the electric field $E$ is inversely proportional to the square of the distance $r$, so $Er^2$ should be constant. Therefore, we can use the graphs of $Er^2$ versus $r$ and $Er$ versus $r$ to determine which data set is for the uniform line of charge and which set is for the uniformly charged sphere.

For data set A, the graph of $Er^2$ versus $r$ is a straight line, which means that $Er^2$ is constant. Therefore, data set A is for the uniformly charged sphere. For data set B, the graph of $Er$ versus $r$ is a straight line, which means that $Er$ is constant. Therefore, data set B is for the uniform line of charge.

For the uniform line of charge, the electric field $E$ is given by

E =[tex]\frac{2\lambda}{4\pi\epsilon_0r}$,[/tex]

where $\lambda$ is the charge per unit length and $\epsilon_0$ is the permittivity of free space. Since $Er$ is constant, we can write $Er = \frac{2\lambda}{4\pi\epsilon_0}$. From the graph of $Er$ versus $r$ for data set B, we can find the slope of the straight line, which is equal to $Er$. Therefore, we can use the slope to calculate $\lambda$:

For the uniformly charged sphere, the electric field $E$ is given by $E = \frac{\rho r}{3\epsilon_0}$, where $\rho$ is the volume charge density. Since $Er^2$ is constant, we can write $Er^2 = \frac{\rho r^3}{3\epsilon_0}$. From the graph of $Er^2$ versus $r$ for data set A, we can find the slope of the straight line, which is equal to $Er^2$.

of incidence of 45 degrees, we can calculate the angle of deviation to be:

θ = sin^(-1)[(1.53 - 1.52) sin(45°) / 1.525] = 0.34°

Therefore, the angular separation between red and blue light leaving the prism is 0.34 degrees.

nλ = d(sin θ_i + sin θ_d)

where n is the order of the diffraction (usually n=1), λ is the wavelength of the light, d is the spacing between the grating lines, θ_i is the angle of incidence of the light on the grating, and θ_d is the angle of diffraction.

θ_red = sin^(-1)[(nλ_red / d) - sin(θ_i)] = sin^(-1)[(1650 nm / 500 nm) - sin(0°)] = 0.837°

θ_blue = sin^(-1)[(nλ_blue / d) - sin(θ_i)] = sin^(-1)[(1450 nm / 500 nm) - sin(0°)] = 0.579°

Newton's second law, which states that the net force exerted on an item is equal to its mass times its acceleration, can be used to address this issue.

Let's use the letters m1 and m2 to represent the masses of the left and right blocks, respectively. The following equations are therefore able to be written:

m1 * a = F - f

m2 * a = f

where F is the size of the applied force, f is the frictional force acting on the blocks, and an is the acceleration of both blocks. Because a string connects the two blocks, it should be noted that the acceleration is the same for both. The frictional force can be expressed as

f = * N,

where is the coefficient of friction and N is the normal force, can be used to express the frictional force. The weight of the blocks, which can be represented as m1 * g and m2 * g, respectively, determines the normal force acting on them.

When we solve for F and replace the frictional force expression in the first equation, we obtain:

F = m1 * a + μ * m1 * g

Inputting the values provided yields:

F = (m1 + m2) * a + μ * (m1 + m2) * g

F = (m1 + m2) * 5.2 + 0.4 * (m1 + m2) * 9.8

F = 5.2 * (m1 + m2) + 3.92 * (m1 + m2)

F = 9.12 * (m1 + m2)

We now need to determine what m1 Plus m2 equals. Although their specific masses are withheld from us, we do know that the ratio of their masses is 2:3. Let's write m for the smaller mass and 1.5m for the larger value. Next, we have:

m + 1.5m = 2.5m

1.5m/m = 3/2

So the masses are m = 2/5 and 1.5m = 6/5.

Inputting these values into the F equation yields the following results:

F = 9.12 * (2/5 + 6/5)

F = 9.12 * 8/5

F = 14.59 N

The speed of the cars right after the collision is 1/3 m/s.

To solve this problem, we can apply the law of conservation of momentum, which states that the total momentum of a system remains constant if there are no external forces acting on it. In this case, the two railroad cars form a closed system, and there are no external forces acting on them during the collision. Therefore, we can write:

(m1 * v1) + (m2 * v2) = (m1 + m2) * v

where m1 and v1 are the mass and velocity of the first railroad car, m2 and v2 are the mass and velocity of the second railroad car, m1 + m2 is the total mass of the system after the collision, and v is the velocity of the system after the collision.

Plugging in the given values, we get:

(1500 kg * 4 m/s) + (3000 kg * (-3 m/s)) = (1500 kg + 3000 kg) * v

Simplifying and solving for v, we get:

v = (1500 kg * 4 m/s - 3000 kg * (-3 m/s)) / (1500 kg + 3000 kg)

The current flowing through potentiometer R is 0.855mA, the current flowing through potentiometer Rį for an RL 5KΩ and the current flowing through potentiometer R is 854μA,

The potentiometer is an instrument used for measuring the unknown voltage by comparing it with the known voltage. It can be used to determine the emf and internal resistance of the given cell and also used to compare the emf of different cells. The relative system is used by the potentiometer. The reading is more accurate in a potentiometer.

1) Rl = 1kΩ

Applying nodal analysis at V:

V/1K + V/3.3K + V-12/1K

3.3V+V+3.3V-39.6/3.3K = 0

7.6V = 39.6

V = 39.6/7.6 = 5.21 V

Il = v/Rl = 5.21/1K

Il = 5.21 mA

For Rl = 1K and Il = 5.21mA

Rl = 5 kΩ

Applying nodal analysis at V:

V/5 K + V/3.3K + V-12/1K

3.3V+5V+16.5V-198/3.3K = 0

24.8V = 198

V = 198/24.8 = 7.98 V

Tl = 7.98/5 K = 1.596 mA

Rl = 10 kΩ

Applying nodal analysis at V:

V/10K + V/3.3K + V-12/1K

3.3V+10V+33V-396/3.3K = 0

46.3V = 396

V = 396/46.3 = 8.55 V

IL = V/Rl = 8.55/10 K = 0.855mA

2) IL = 12m x 0.767K/0.767K + 10K

= 12m x 0.767/10.767

= 0.854 mA

= 854 μA

Correct, low, quiet voices have sound waves with low frequency and low amplitude. Instead of hearing, the vestibular system controls balance and spatial orientation.

In order to determine where a sound is coming from, humans rely on two key clues. These signals include (1) the ear the sound strikes first (interaural temporal differences) and (2) the volume of the sound when it reaches each ear (known as interaural intensity differences).

Sound waves enter the outer ear and travel to the eardrum via the auditory canal. The three tiny ossicles carry the ensuing vibrations into the cochlea, where hair cells are able to pick them up.

(a) The initial velocity of the projectile is 42.23 m/s.

(b) The maximum height reached by the projectile is 91 m.

The initial velocity of the projectile is calculated by applying the following kinematic equation.

v = ( 24.0 î - 8.00j ) m/s

The angle of projection is calculated as;

θ = arc tan ( Vy / Vx )

θ = arc tan ( 8 / 24 )

θ = 18.43⁰

h = ( u² sin²θ ) / 2g

u² = 2gh / (sin²θ)

u² = ( 2 x 9.8 x 9.1 ) / ( sin 18.43 )²

u² = 1783.6

u = √1783.6

u = 42.23 m/s

The maximum height reached by the projectile is calculated as follows;

v² = u² - 2gh

where;

2gh = u²

h = ( u² ) / ( 2g)

h = ( 42.23² ) / ( 2 x 9.8 )

h = 91 m

The worker can load {500/ρ} number of bricks into the van.

Mass is the total amount of matter present inside a body.

Given is that a worker wants to load some bricks in to his van. There are 1000 bricks and when stacked neatly they measure 2m by 1m by 1m.

Assume the density of the brick to be {ρ}. Let's assume that he can load {n} bricks inside the van. So, we can write -

n x mass of 1 brick = maximum load

n x ρ x V = L{max}

nρV = L{max}

n = L{max}/ρV

n = 1000/(2 x 1 x 1 x ρ)

n = 500/ρ

Therefore, the worker can load {500/ρ} number of bricks into the van.
