How does heat metal work armor 5e?

The kinetic energy of the wheel, with an angular speed of 3000rev/min if the radius gyration of the wheel is 12cm,  is approximately 24,568.15 Joules.

To determine the kinetic energy of the wheel, we'll need to use the following formula:

Kinetic Energy (KE) = 0.5 * I * ω²

Where I is the moment of inertia, and ω is the angular speed in radians per second.

First, we need to convert the angular speed from rev/min to radians per second:

ω = 3000 rev/min * (2π radians/rev) * (1 min/60 sec) = 314.16 radians/sec

Next, we can calculate the moment of inertia using the mass (35 kg) and radius of gyration (0.12 m):

I = m * k² = 35 kg * (0.12 m)² = 0.504 kg*m²

Finally, we can find the kinetic energy:

KE = 0.5 * 0.504 kg*m² * (314.16 radians/sec)² = 24,568.15 J

The kinetic energy of the wheel is approximately 24,568.15 Joules.

Answer: A

Explanation:

The moon has less mass than Earth.

Just took the test.

The successful tackle between the 90.0-kg fullback running east and the 95.0-kg opponent running north constitutes a perfectly inelastic collision. In a perfectly inelastic collision, the two objects stick together after the collision, resulting in a combined mass and velocity.

The tackle meets this criterion because the two players become entangled and move as a single unit after the collision, exhibiting a loss of kinetic energy and a change in direction. The collision is considered perfectly inelastic because the two objects remain in contact and move together after the impact.

In a perfectly inelastic collision, the two colliding objects stick together and move as a single unit after the collision. This occurs because there is a strong interaction or adhesive force between the objects, causing them to become entangled and lose their individual identities.

In the given scenario, when the fullback running east and the opponent running north collide, the two players become intertwined and move together as a combined system. This outcome indicates a loss of kinetic energy during the collision.

The momentum of the system is conserved, but the original kinetic energy is transformed into other forms, such as internal energy or heat.

The successful tackle constitutes a perfectly inelastic collision because the two players remain in contact and continue to move together after the collision. Their masses and velocities combine, resulting in a single entity with a new velocity and direction.

This type of collision is common in contact sports such as football, where players collide and stick together to bring the opposing player to a stop.

The displacement of the speedboat after 10.0 seconds is 230.0 meters.

The displacement of an object with constant acceleration can be found using the formula:

d = vₒt + (1/2)at²

where d is the displacement, vₒ is the initial velocity, t is the time elapsed, and a is the acceleration.

Given the initial velocity of 8.0 m/s and acceleration of 3.0 m/s², and a time elapsed of 10.0 seconds, we can plug in the values into the formula to find the displacement:

d = 8.0 m/s × 10.0 s + (1/2) × 3.0 m/s² × (10.0 s)² = 80.0 m + 150.0 m = 230.0 m

So the displacement of the speedboat after 10.0 seconds is 230.0 meters. This means the boat has moved 230.0 meters from its original position due to the combined effect of its initial velocity and the acceleration.

The angle θ is approximately 0.688°, and the angle θ' is approximately 1.988°.

To determine the angles θ and θ' in the given scenario, we can use Snell's Law, which relates the angles of incidence and refraction to the refractive indices of the media involved. Snell's Law can be stated as follows:

n₁ * sin(θ₁) = n₂ * sin(θ₂)

Where:

n₁ is the refractive index of the medium of incidence (in this case, air with a refractive index close to 1),

θ₁ is the angle of incidence,

n₂ is the refractive index of the medium of refraction (in this case, linseed oil with a refractive index of 1.48), and

θ₂ is the angle of refraction.

Let's solve for the unknown angles θ and θ' using the given information.

Given:

Angle of incidence θ = 1°

Refractive index of linseed oil n₂ = 1.48

We need to find the angle of refraction θ₂.

Using Snell's Law, we have:

n₁ * sin(θ₁) = n₂ * sin(θ₂)

Since the refractive index of air (n₁) is approximately 1, we can simplify the equation to:

sin(θ₁) = n₂ * sin(θ₂)

Plugging in the values:

sin(1°) = 1.48 * sin(θ₂)

We can now solve for θ₂:

θ₂ = arcsin(sin(1°) / 1.48)

Calculating this value, we find:

θ₂ ≈ 0.688°

Now, let's determine the angle θ'.

Given:

Angle of refraction θ₂ = 0.688°

Refractive index of linseed oil n₂ = 1.48

We need to find the angle of incidence θ'.

Using Snell's Law, we have:

n₂ * sin(θ₂) = n₁ * sin(θ')

Since the refractive index of air (n₁) is approximately 1, we can simplify the equation to:

n₂ * sin(θ₂) = sin(θ')

Plugging in the values:

1.48 * sin(0.688°) = sin(θ')

Solving for θ', we find:

θ' = arcsin(1.48 * sin(0.688°))

Calculating this value, we get:

θ' ≈ 1.988°

Therefore, the angle θ is approximately 0.688°, and the angle θ' is approximately 1.988°.

The voltage drop across the 18 kΩ resistor is 90 volts. This means that when a current of 5 mA flows through an 18 kΩ resistor, there is a potential difference of 90 volts across the resistor.

To calculate the voltage drop across a resistor, Ohm's Law can be applied. Ohm's Law states that the voltage (V) across a resistor is equal to the product of the current (I) flowing through it and the resistance (R) of the resistor. The formula for Ohm's Law is V = I * R.

Given:

Current (I) = 5 mA = 5 * 10^(-3) A

Resistance (R) = 18 kΩ = 18 * 10^(3) Ω

Using Ohm's Law, we can calculate the voltage drop (V):

V = I * R

= (5 * 10^(-3) A) * (18 * 10^(3) Ω)

= 90 V

Therefore, the voltage drop across the 18 kΩ resistor is 90 volts. This means that when a current of 5 mA flows through an 18 kΩ resistor, there is a potential difference of 90 volts across the resistor.

Based on the direction of the currents specified in the figure, we can write the equation:

i2 + i3 = i1

This equation represents the application of KCL at the node where i1, i2, and i3 are connected. According to KCL, the sum of currents entering the node (i2 and i3) is equal to the sum of currents leaving the node (i1).

Change in angular velocity is always created when a net torque is applied to a rigid body. Thus, option I. is the correct answer.

I. Change in angular velocity: When a net torque is applied to a rigid body, it changes the body's angular velocity. The magnitude and direction of the angular velocity depend on the net torque and the moment of inertia of the body. Thus, Option I is the correct option.

II. Rotational equilibrium:  Rotational equilibrium can be defined as the condition where the net torque acting on a body is zero, resulting in a constant angular velocity. However, applying a net torque will generally lead to a change in the angular velocity, which will result in a rotational acceleration rather than rotational equilibrium. Therefore, this option is not always created when a net torque is applied to a rigid body.

III. Constant angular velocity:  A net torque can change the body's angular velocity, which will result in either an increase or a decrease in the angular velocity. Therefore, this option is not always created when a net torque is applied to a rigid body.

IV. Constant angular momentum:  When a net torque is applied to a rigid body, the angular momentum of the body is not necessarily constant. Angular momentum is conserved in the absence of any external torques acting on the body. However, the angular momentum can change when a net torque is present. Therefore, this option is incorrect.

Answer:

Option C. f¯¹(x) = (5x + 3)/2

Explanation:

f(x) = (2x – 3)/5

We can obtain the inverse of the above equation as follow:

Let f(x) be y.

Therefore,

F(x) = (2x – 3)/5

y = (2x – 3)/5

Next, we shall interchange the position of 'y' and 'x'. This is illustrated below:

y = (2x – 3)/5

x = (2y – 3)/5

Next, we shall make y the subject of the expression. This is illustrated below below:

x = (2y – 3)/5

Cross multiply

2y – 3 = 5x

Rearrange

2y = 5x + 3

Divide both side by 2

y = (5x + 3)/2

Therefore, the inverse of

f(x) = (2x – 3)/5 is f¯¹(x) = (5x + 3)/2

It took two centuries for the Copernican model to replace the Ptolemaic model because of its revolutionary heliocentric concept and the resistance from the prevailing geocentric worldview.

The Copernican model, proposed by Nicolaus Copernicus in the 16th century, placed the Sun at the center of the solar system with the planets, including Earth, orbiting around it. This model challenged the long-standing Ptolemaic model, which placed Earth at the center.

The acceptance of the Copernican model was hindered by several factors. Firstly, the Ptolemaic model had been the dominant cosmological framework for over a millennium and was deeply entrenched in both scientific and religious circles.

The new model threatened established beliefs and required a significant shift in thinking.

Additionally, the Copernican model initially faced challenges in accurately predicting celestial phenomena. It took advancements in observational instruments and mathematical techniques, such as Johannes Kepler's laws of planetary motion and Galileo Galilei's telescopic observations, to provide compelling evidence in favor of the heliocentric model.

Over time, as the evidence in support of the Copernican model accumulated and its predictive power became undeniable, it gradually gained acceptance among scientists and scholars.

The widespread adoption of the heliocentric model eventually transformed our understanding of the cosmos.

Pluto is no longer considered a planet as a result of it's small size on the IAU scale.

Explanation:

When spring constant k is 32 N/m and the spring stretch from the equilibrium position is 27 cm is 1.1664 Joules.

Ability of an object or material to regain its normal shape after being stretched or compressed is called elasticity. For example, A rubber gets its shape  stretch because of its elastic property.

It can also be defined as the ability of a body to resist a distorting influence and to return to its original shape when the force is removed.

Given spring constant k is 32 N/m and the spring stretch from the equilibrium position is 27 cm

27 cm = 0.27m

we can find the spring's potential energy from the equation:

PE = 0.5 * spring constant * ( extension)^2

= 0.5 *32 *(0.27)^2

= 1.1664 Joules
