I-ready dianostic: in passage 2, which plot event best supports the theme that things are not always what they seem?

The basketball player must throw the basketball at an initial speed of 8.19 m/s so that it goes through the hoop without striking the backboard.

Initial speed refers to the magnitude of the velocity of an object before it starts accelerating.

We can use the following kinematic equations to solve for the initial speed of the basketball:

\(V_y = V_{oy} + a_y\times t\)

\(V_y = V_{oy} \times t + 1/2(a_y \times t^2)\)

where \(V_y\) is the vertical component of the velocity, \(V_{oy}\) is the initial vertical component of the velocity, ay is the acceleration due to gravity (-9.81 m/s²), y is the vertical displacement, t is the time of flight,

Since the basketball player wants to throw the ball through the hoop without striking the backboard, the ball needs to travel a horizontal distance of 10.0 m and a vertical distance of (3.05 - 2) m. The initial angle of 40.0 degrees can be broken down into its horizontal and vertical components:

\(V_{oy} = V_o sin(40.0)\)

\(V_{ox} = V_o cos(40.0)\)

where \(V_o\) is the initial velocity.

Using the second kinematic equation, we can solve for the time of flight:

\(10 = V_{ox}t + 1/2a_xt^2\)

\(10 = V_o cos(40.0) t\)   (since ax = 0)

\(t = 10/(V_o cos(40.0))\)

Now using the time of flight in the vertical direction:

\(1.05 = V_o sin(40.0) \times 10/V_o cos(40.0) - 1/2\times 9.81 * (10/(V_o cos(40.0)))^2\)

\(1.05 = 8.39 - 835/V_o^2\)

\(V_o = 10.1 \ m/s\)

Therefore, the basketball player must throw the basketball at an initial speed of approximately 10.1 m/s (to three significant figures) in order to make the shot without striking the backboard.

No. of turns of wire would be required to make a 120 mh inductance out of a 33.0 cm -long air-filled coil with a diameter of 4.1 cm is μ*2740.68 as μ is variable for different types of material.

An electrical conductor's propensity to resist a change in the flow of current through it is known as inductance. A magnetic field is produced around a conductor by an electric current flowing through it. The magnitude of the current determines the field strength, which follows any changes in current.

The formula of Inductance is L = μN2A/l  where L = Inductance (H), μ = Permeability (Wb/Am),N = The coil's number of turns, A = The coil's cross sectional area =  π*d²/4, l = Length of coil (m)

Now acc. to the given data

L=120mh

I=33.0cm =0.33m

Diameter=4.1cm

A= π*d²/4 = 3.14*4.12/4

A=13.19cm2or 0.001319m2

Now rearranging the formula for no. of turns we get

N=√LI/μA

So, N=√ 120*0.33/μ*0.001319

N=μ*2740.68

Hence, no. of turns of wire would be required to make a 120 mh inductance out of a 33.0 cm -long air-filled coil with a diameter of 4.1 cm is μ*2740.68 as μ is variable for different types of material.

Answer:

La posición en la que se encuentra el móvil en el instante t = 30 s es 172 m.

Explanation:

El movimiento rectilíneo uniforme (MRU) es el movimiento que describe un cuerpo o partícula a través de una línea recta a velocidad constante.

La distancia recorrida,  x , por un móvil que tiene un MRU con un velocidad  v  durante el intervalo de tiempo  t  es:

x= x0 + v*t

donde x0 es la posición inicial.

En este caso:

Reemplazando:

x= 22 m + 5 m/s* 30 s

Resolviendo:

x= 22 m + 150 m

x= 172 m

La posición en la que se encuentra el móvil en el instante t = 30 s es 172 m.

The potential difference across all three resistors in a series circuit is the same, as the voltage from the battery is divided across the resistors in proportion to their resistance values. Therefore, option B (potential difference ΔV) is the same for all three resistors.

The resistance of each resistor is different, so option C is not the same for all three resistors.

The current through each resistor is the same, as there is only one path for the current to flow in a series circuit. Therefore, option A (current I) is the same for all three resistors.

So the correct answer is D, "A and B".

The period of a simple pendulum of length 1m on a massive planet is 1 sec. The acceleration due to gravity on that planet is 39.48 m/s^2.

A simple pendulum's period is given by:

T = 2π √(L/g)

Where T is the pendulum's period, L is its length, and g is the acceleration due to gravity.

In this scenario, the pendulum's period is one second and its length is one metre.

So, from above equation, we have:

1 = 2π √(1/g)

Squaring both sides, we get:

1^2 = (2π)^2 (1/g)

Simplifying, we get:

g = (4π^2)/1 = 39.48 m/s^2

Therefore, the acceleration due to gravity on the massive planet is 39.48 m/s^2.

The angular acceleration is -0.0045 rad/s²

Explanation:

Given;

angular distance of the flywheel, θ = 40 rev

initial angular speed, \(\omega_i\) = 1.5 rad/s

When the wheel comes to rest, the final angular speed, \(\omega_f\) = 0

The angular acceleration is calculated as follows;

\(\omega_f^2 = \omega_i^2 + 2\alpha \theta \\\\0 = (1.5 \ rad/s)^2 + 2\alpha (40 \ rev\times \frac{2\pi \ rad}{1 \ rev} )\\\\0 = 2.25 + 160\pi \alpha\\\\160\pi \alpha = - 2.25\\\\\alpha = -\frac{2.25 }{160\pi} \\\\\alpha = -0.0045 \ rad/s^2\)

The time of motion is calculated as;

\(\omega_f = \omega _i + \alpha t\\\\0 = 1.5 + (-0.0045t)\\\\0 = 1.5 - 0.0045t\\\\0.0045t = 1.5\\\\t = \frac{1.5}{0.0045} = 333.3 \ s\)

The magnitude of the average velocity of the woodchuck is 0.71 m/s. The average speed of the woodchuck is 3.2 m/s.

Right distance = 19m

Time is taken to cover distance = 4.8s

Left distance = 12m

Time is taken to cover distance = 5s

total displacement = 19 m to the right - 12 m to the left = 7 m to the right

A. To calculate the magnitude of the average velocity, we need to find the total displacement and divide it by the total time.

The total time it took for the woodchuck to run both distances is:

The total time = 4.8 s + 5 s

The total time = 9.8 s

The magnitude of the average velocity is:

v = displacement/time

v  = 7 m / 9.8 s

v = 0.71 m/s

B. To find the average speed, we need to calculate the total distance traveled and divide it by the total time.

The total distance traveled is = 19 m + 12 m = 31 m

The total time it took for the woodchuck to run both distances is:

The average speed = total distance / total time

The average speed = 31 m / 9.8 s = 3.2 m/s

Therefore we can conclude that the magnitude of the average velocity is 0.71 m/s and the average speed is 3.2 m/s.

Explanation:

The Earth rotates on its axis every 24 hours (relative to the Sun) and revolves in orbit around the Sun once every year.

The most direct evidence of daily rotation is via a Foucault pendulum, which swings in the same plane as the Earth rotates beneath it. At either pole, the swinging plane mirrors the Earth's 24 hour period. Some rotation is observed at all other locations on the Earth's surface as well, except for the equator.

The most direct observational evidence for Earth's orbital motion is the apparent shift of nearby stars after six months, as the Earth moves from one side of its orbit to the other. Because of the large distance to even the nearest start, this parallax shift is too small to been seen without a telescope.

So the Earth rotates around its axis as it revolves around the sun. It takes the Earth 365 days, or one year, to complete a revolution. Leftover momentum from when planets were forming makes the Earth, and all planets in the solar system, rotate and revolve.

The star Betelgeuse is about 600 light-years away. If it explodes tonight, approximately: we won't know about it until 600 years from now.

Rather than measuring time, a light-year measures distance (as the name might imply). The distance a light beam travels in a single Earth year is measured in "light-years," which is roughly equivalent to 6 trillion miles (9.7 trillion kilometers).

Because the cosmos is expanding, the light that goes the farthest is stretched the most, resulting in the object that emitted that light being farther away. The expanding cosmos is the reason we can see things up to 46.1 billion light-years away. According to a common model of the Universe, some of the most recently discovered objects may be more than 13 billion light years away.

At each end of a long bone is an expanded portion called an "epiphysis," which articulates (or forms a joint) with another bone.

An epiphysis is a rounded or flat surface located at the ends of a long bone and is covered by a layer of smooth articular cartilage. This cartilage provides a low-friction surface that allows for smooth and pain-free movement between the bones at the joint. The epiphysis is separated from the main shaft of the bone (the diaphysis) by the epiphyseal plate, a layer of hyaline cartilage that allows for growth in children and adolescents. The epiphysis and diaphysis are joined together by a strong and flexible tissue called the epiphyseal line, which eventually fuses in adulthood and forms a solid connection between the two parts of the bone. The epiphysis and diaphysis work together to provide strength, stability, and support to the bones of the skeleton, and the joints formed by the articulation of the epiphysis and another bone play a crucial role in enabling movements such as walking, jumping, and twisting.

In short, an epiphysis is an expanded portion at the end of a long bone that articulates with another bone to form a joint, and it plays an important role in the movement and stability of the skeleton.
