6. Which Thanksgiving dish contains the most dietary fiber ? (Corn) (Mashed Potatoes) (Sweet Potatoes) (Pecan Pie)
Answer:
The correct option is;
Sweet Potatoes
Explanation:
The dietary fiber in Corn = 2.7 g per 100 g
The dietary fiber in Mashed Potatoes = 1.3 g per 100 g
The dietary fiber in Sweet Potatoes = 3 g per 100 g
The dietary fiber in Pecan Pie = 2.1 g per 100 g
Therefore, the Thanksgiving dish that contains the most dietary fiber per 100 g is Sweet Potatoes
3. As the ice melts into liquid water, what happens to the kinetic energy of the particles in the sample?
4. How does the kinetic energy of the particles in the sample relate to the sample’s temperature?
Answer:
As ice melts into water, kinetic energy is being added to the particles. This causes them to be 'excited' and they break the bonds that hold them together as a solid, resulting in a change of state: solid -> liquid.
Explanation:
As the ice melts into liquid water, the kinetic energy of the particles in the sample increase. The temperature of the sample is directly proportional to the kinetic energy of the particle.
What is Kinetic energy?The kinetic energy of an object is the energy which it possesses due to the motion of the object. Kinetic energy is defined as the work which is needed to accelerate a body of a given mass from the rest position to its stated velocity. The body of an object maintains the same amount of kinetic energy which it gained during its acceleration unless its speed changes.
The temperature is directly proportional to the kinetic energy of the object. As the temperature of the object increases the phase of the object changes from solid to liquid.

Water boils at 100°C and turns into steam. Which similarities or differences are there between water in these two states? (1 point)
The particles will have more space between them and will be moving at higher speeds as steam.
The particles will have more space between them as steam, but they will be moving at the same speed in both states.
The particles will have more space between them as a liquid, but they will be moving at the same speed in both states.
The particles will have more space between them as a liquid, but they will be moving faster as steam.
Answer:
My answer was A not sure if its correct as i am still doing the rest of the questions.
Explanation:
The particles will have more space between them and will be moving at higher speeds as steam compare to water.
What is latent heat ?The quantity of heat (in joules or calories) per mole or unit mass of the substance undergoing a change in state is the typical way to represent latent heat.
The latent heat involved in melting solids or freezing liquids is referred to as the "heat of fusion," while the latent heat involved in vaporizing solids or liquids or condensing vapor is referred to as the "heat of vaporization."
When water boils at 100°C and turns into steam, water vaporizes into steam by absorbing heat of vaporization. This heat energy remains in the steam as kinetic energy and makes their movement fast.
So, The molecules will have more space between them and will be moving at higher speeds as steam compare to water.

A crate weighing 523 N rests on a plank that makes a 22.0 angle with the ground. Find the components of the crate's weight force parallel and perpendicular to the plank. ( Fgx = –196 N, Fgy = –485 N)
Answer:
Explanation:
The weight of the crate will e equal to its normal reaction R
Since R = mgsin theta = W
W = mgsintheta ( resolved along the vertical perpendicular to the plank
Fy = 523sin22°
Fy = 195.92N
Since the weight is acting along the negative y direction,
Fy = -195.92N
The force parallel to the plank will be the force acting in the horizontal direction.
Fx = Fcos theta
Fx = 523cos 22°
Fx = 484.9N
Which shows the correct angle of reflection given the incident ray shown?
[tex]\mathfrak{\huge{\pink{\underline{\underline{AnSwEr:-}}}}}[/tex]
Actually Welcome to the Concept of the Rays of light.
Since we know that, The light ray on a shiny surface makes a angle with the normal, hence The Angle of incidence is equal to angle of reflection made with Normal Axis in the middle.
Thus Option c.) is correct.
C.) is the Answer.
The angle of reflection given the incident ray from the given diagrams is option C.
What is the refraction of light?When a light ray strikes the shining surfaces, the part of the light gets refracted. The bouncing back of the light is called reflection. When the light strikes the surface is called an incident ray.
When the light ray incident on the surface, the light returns back to the same medium is called reflection. The laws of reflection are, the angle of incidence is equal to the angle of reflection, and the incident ray, reflected ray, and normal takes place in the same plane. The speed of light remains the same in the process of reflection.
The reflected light ray changes the path of direction in the same medium. When a light ray enters from one medium to another, the speed of light gets decreases.
Thus, the ideal solution is option C.

What is the momentum of a 10 kg object traveling at 4 m/s?
A 200kg car is coasting to the right and slowing down due to a friction force of 200N.
By Newton's second law, the net force on the car is
∑ F = m a
where m is the mass of the car and a is magnitude of the acceleration.
The car is slowing down, so the net force opposes the direction in which the car is moving. Vertically, the car is in equilibrium, the net force is entirely due to friction. Taking the direction opposite the car's motion to be negative, we have
- 200 N = (200 kg) (-a)
a = (200 kg) / (200 N)
a = 1 m/s²
If you're also supposed to find the coefficient of kinetic friction, use the fact that the car the vertical forces cancel out, namely
n + (-w) = 0
where n is the magnitude of the normal force and w is the car's weight. The friction force f is proportional to the normal force n by a factor of µ, the coefficient of kinetic friction, such that f = µ n. Then
f / µ = w
(200 N) / µ = (200 kg) (9.80 m/s²)
µ = (200 N) / ((200 kg) (9.80 m/s²))
µ ≈ 0.102

Explanation:
because it's top speed is 50km/h,so it's initial speed may be less. when it covers some distance it's speed changes again. then we have given a mean speed .mean speed means sum of all speed divided by sum of total time.so the mean speed and final speed differs from each other
