Another of Chef Kylie's more celebrated dishes is the Hamslaughter Supreme. This dish features ham stuffed sausage links presented in a basket made of braided bacon. While carnivores around the world roar for Chef Kylie's creations, it is unlikely that Chef Kylie will dine with them. As a longtime vegan, Chef Kylie would never dream of devouring one of his own dishes. What type of irony? explain your answer
Answer:
situational irony
Explanation:
Based on the scenario being described, this seems to be an example of situational irony. That is because the irony in this scenario is that Tim's most popular and world-renown cooking creations are made of meat but Tim is a vegan and does not consume meat, which all revolves around the situation that Tim is in. Since he can't enjoy the meals with his fans because he does not eat the ingredients in his own creation. Therefore, being specific to the situation that Tim has created.
If a car travels 40 mph for a distance of 1680 miles, how much time did it take?
Answer:
42 hour
Explanation:
It is given that,
Speed of a car, v = 40 mph
Distance covered by the car, d = 1680 miles
We need to find the time taken by the car to cover this distance. We can find it using the formula of speed which is equal to the distance covered divided by the time taken. Let the time is t.
speed = distance/time taken
[tex]t=\dfrac{d}{s}\\\\t=\dfrac{1680\ \text{miles}}{40\ \text{mph}}\\\\t=42\ \text{hour}[/tex]
Hence, the car will take 42 hours to cover 1680 miles with a speed of 40 mph.

For which trial would the students measure the smallest current in the circuit?
Answer: C. Trial 3
Explanation:
Trial 1 and 2 equal 1.5, Trial 3 equals 1 and Trial 4 equals 3. Trial 3 is the smallest current .
The trial for which the students would measure the smallest current is the circuit is trial 2 and trial 3.
To know the trial which generates the smallest current, we need to determine the current in each trial.
Since current I = V/R where V = voltage and R = resistance.
For trial 1, V = 1.5 V and R = 200 Ω
So, I = 1.5 V/200 Ω
= 0.0075 A
= 7.5 mA
For trial 2, V = 1.5 V and R = 100 Ω
So, I = 1.5 V/100 Ω
= 0.015 A
= 15 mA
For trial 3, V = 3 V and R = 200 Ω
So, I = 3 V/200 Ω
= 0.015 A
= 15 mA
For trial 4, V = 3 V and R = 100 Ω
So, I = 3 V/100 Ω
= 0.03 A
= 3 mA
Trial 2 and trial 3 both produce a the smallest current of 15 mA.
So, the trial for which the students would measure the smallest current is the circuit is trial 2 and trial 3.

What is Electrical energy?When put in an electromagnetic field, charged matter experiences a force due to the fundamental property of electric charge. Positive or negative electrical ions are possible.
When two charges are in opposition to one another, they repel one another. The term "neutral" refers to an object that has no net charge. The early understanding of the way charged particles interact is now referred to as classical electrodynamics, and it is still true for issues that do not demand taking into account quant phenomena.
Electrical charge is a preserved attribute, meaning that the net charge of an isolated system—that is, the sum of the positive and negative charges—cannot change. Particles at the subatomic level carry an electric charge.
As per the data given in the question,
Current, I = 15 A
Resistance, R = 0.10 ohms
Then, the voltage (V) will be,

If a ball is rolled down a frictionless inclined plane from a height of 3 feet, to what height would it roll up to on the other side?
Answer:
It will roll up to its initial height from which it rolled from on the first hill
Explanation:
The given information are;
The height from which the ball is rolled = 3 feet[
The equation of the potential energy of the ball as it rolled down the frictionless inclined plane is given by the following equation;
m × g × h₁ = 1/2 × m × v² + 1/2×[2/5× m × r²) × [v/r]
Where;
m = The mass of the ball
h = The from which the ball is rolled down
v = The velocity of the ball
r = The radius of the ball
Therefore, all the potential energy, m × g × h, is converted into kinetic energy when the ball reached the ground
Similarly, as the ball rolls up on the other side, by the principle of energy conservation, all the kinetic energy is transformed into potential energy as follows
1/2 × m × v² + 1/2×[2/5× m × r²) × [v/r] = m × g × h₂, therefore, we have;
1/2 × m × v² + 1/2×[2/5× m × r²) × [v/r] = m × g × h₁ = m × g × h₂
Therefore since m × g × h₁ = m × g × h₂, then h₁ = h₂, the ball rises to the same height it started rolling from on the first hill.
A ball of mass 200 g rolls along the ground at a speed of 5.2 m/s. Calculate the kinetic energy of the ball.
Answer:
We have a mass of 200g (0.2kg) moving at 20m/s
Kinetic Energy KE = ½ mv^2 where m is mass and v is velocity
Actually, v is a vector quantity, so KE = ½ mv•v
The dot product of 2 vectors a and b is abCosθ where θ is the angle between the vectors.
Obviously v•v = v^2 Cos0 = v^2
In this case, we have KE = ½ (0.2)(20^2) = 40kg-m^2/s^2 = 40J
So we have kinetic energy in the amount of 40 Joules.
Explanation:
The right answer is "2.7 J"
Answer explanation:
Remember to convert grams to kilograms first by dividing by 1000.
Kinetic energy
= 1/2 × mass × speed2
= 1/2 × 0.2 kg × (5.2 m/s)^2
= 2.7 J (to 2 sig. fig.)

What affect does doubling the net force have on the acceleration of the object (when
the mass of the object stays the same)? Identify a set of two trials that support your answer to question 1
===========================================================
Explanation:
Consider a mass of 10 kg, so m = 10
Let's say we apply a net force of 20 newtons, so F = 20
The acceleration 'a' is...
F = ma
20 = 10a
20/10 = a
2 = a
a = 2
The acceleration is 2 m/s^2. Every second, the velocity increases by 10 m/s.
---------------
Now let's double the net force on the object
F = 20 goes to F = 40
m = 10 stays the same
F = ma
40 = 10a
10a = 40
a = 40/10
a = 4
The acceleration has also doubled since earlier it was a = 2, but now it's a = 4.
---------------
In summary, if you double the net force applied to the object, then the acceleration doubles as well.
Acceleration is directly proportional to the net force on an object, and inversely proportional to its mass.
So if an object's mass stays the same while the net force on it doubles, then its acceleration will also double.
We don't know anything about the "trials". This sounds like it might be a follow-up to a lab experiment that was performed when we weren't there.
We also don't know anything about "question 1".

22. Explain in detail what happens to particles before, during, and after vaporization.
Answer:
Vaporization occurs when a substance changes from a liquid to a gas. The molecules in a liquid are in constant motion while staying relatively close together due to intermolecular forces. When an increase in temperature occurs, the molecules' kinetic energy also increases. If a liquid is heated the particles are given more energy and move faster and faster expanding the liquid. The most energetic particles at the surface escape from the surface of the liquid as a vapor as it gets warmer. Liquids evaporate faster as they heat up and more particles have enough energy to break away.

Answer:
1) False, since constant speed means constant velocity, but with constant direction as well. Velocity is speed with direction. When you move in a circle, there are boundaries which means that a constant moving speed will cause the object to veer(move in different directions) to maintain movement, If it doesn't veer, the object will deflect(rebound) off the surface due to friction, and impact force or depending on its physical bond of malleability or density.
2a) Create position vectors by drawing a ray from the center(origin) of the circle to each of your desired points, it's magnitude will be the radius(how convenient). Both of these vectors go from the center of the circle to the position on the circle. In general, the distance from the origin to a point is called the radius vector.

what is measurement ?
Answer: Measurement is the assignment of a number to a characteristic of an object or event, which can be compared with other objects or events. The scope and application of measurement are dependent on the context and discipline. In the natural sciences and engineering, measurements do not apply to nominal properties of objects or events, which is consistent with the guidelines of the International vocabulary of metrology published by the International Bureau of Weights and Measures. However, in other fields such as statistics as well as the social and behavioural sciences, measurements can have multiple levels, which would include nominal, ordinal, interval and ratio scales.

Fy is the reaction force from Plate Y. What Statement best describes the action and reaction forces on the plates? Tectonic plates
Answer:
According to Newton's third law of motion, the reaction force is equal to the action force.
Explanation:
Newton's third law of motion states that for every action there is an equal and opposite reaction. This means that if one object exerts a force on a second object, the second object exerts an equal force in the opposite direction. When Plate X pushes on Plate Y with the action force (Fx), Plate Y must push back with an equal force (Fy).
Therefore, the best explanation is that according to Newton's third law of motion, the reaction force is equal to the action force.
For every action, there has equal and opposite reaction - this statement best describes the action and reaction forces on the plates.
What is Newton's 3rd law of motion?As a result of this interaction, there are two forces: one from plate X and one from plate Y. The third law of motion of Newton deals with these two forces, which are referred to as action and reaction forces. Newton's third law is officially expressed as follows: There is an equal and opposite reaction to every action.
The implication of the statement is that there are always two forces acting on the two interacting objects. The force acting on the first object is equal in size to the force acting on the second. The force acting on the first object is acting in the opposite direction to the force acting on the second object. Force pairs—equal and opposing action-reaction force pairs—always exist in pairs.
