Answer:
Voltage is a measure of how much energy is delivered to charge. At its most basic, an electron (basic charge) is imparted 1.602×10^−19 joules when moved through an electric potential difference of one volt. An electron is then said to have an energy of 1 electronvolt. So, voltage is energy divided by charge.

In a paragraph, contrast the characteristics between anorexia and bulimia
Answer:
Anorexia disease is a disease where you eat to little and you exercise for long periods of time. They feel over weight when they are actually underweight. They weight themselves and restrict the food they eat. People with anorexia die from starvation. Bulimia disease is when people eat too much food. They do forced vomiting, excessive use of laxatives or diuretics, fasting, excessive exercise, or a combination of these behaviors. They have normal weight.

A hockey puck slides with constant velocity. Which claim about the forces acting on the hockey puck must be true? Choose 1 answer: Choose 1 answer: (Choice A) A There is not enough information. (Choice B) B There is no net force on the hockey puck. (Choice C) C There is a net force on the hockey puck. (Choice D) D There are no forces on the hockey puck.
Answer:
Choice B) B There is no net force on the hockey puck.
Explanation:
In case when the hockey puck the slides with the same velocity or constant velocity so the force with respect to the hockey should contain that there is no net force as if the body moves along with the same velocity or the constant velocity so in this case the body acceleration is zero
And according to the newton second law i.e.
F = ma
In case when the acceleration is zero so the net force is zero
Therefore the option b is correct

The Concord jetliner achieves a lift-off speed of 112 m/s in 20.0 seconds, starting from rest and traveling due east. What is the magnitude and direction of the average acceleration?
Answer:
5.6 m/s
Explanation:
The acceleration of any possible is the ratio of the velocity of the particle with respect to the time the particle takes in moving. It is mathematically represented as
a = v/t, with m/s² as it's unit, where
v = velocity in m/s
t = time taken in seconds
a = acceleration in m/s²
From the explanation above, we were given in the question that, the speed is 112 m/s and the time if took is 20 seconds, thus, the acceleration is
a = 112/20
a = 5.6 m/s²
Therefore, the magnitude of the acceleration is 5.6 m/s²

A horse is grazing for food. It trots rightward 15 m to eat a carrot, then walks rightward 20 m, to another carrot, then turns leftwards to walk 4m, to bite an apple. The horse walks a total time of 74 seconds. What is the magnitude of its average velocity?
(** HINT- you may want to draw this out, remember with VELOCITY direction matters-opposite vectors cancel out-with SPEED direction does not matter).
Answer:
0.42sExplanation:
Velocity = Displacement/time
Displacement of the horse is the distance covered in a specified direction
Total distance of the horse towards the right = 15m + 20m = 35m
Total distance of the horse towards the left = 4m
Displacement = Distance towards the right - Distance towards the left
Displacement = 35m-4m
Displacement = 31m
Time taken = 74seconds
substitute the values gotten into the velocity formula
average velocity = 31m/74s
average velocity = 0.42m/s
Hence the magnitude of its average velocity is 0.42s

Cuál es el método que utiliza el factor de la gravedad y la difusión de un líquido sobre un sólido para separar las partes de una mezcla de varios líquidos mezclados entre sí
Answer:
chromatography
Explanation:
Chromatography is one of the powerful technique that is used to separate the mixed components of liquid or the gas mixtures.
In this technique the separation of the mixture by passing the mixture in some solution or some suspension through the medium where the components are made to move at some different rates.
The basic idea in this experiment is that the mixture sample is in mobile phase and it is forced either by pumping or by gravity or by capillary action through the stationary phase to separate the mixture.
Use the picture to answer the question. Name at least three physical properties of the bowling ball.
Answer:
Density, Color, and Luster.
Explanation:
Density, describes how compact the matter is in a substance. A bowling ball is more dense than a beach ball. Color - Describes how light reflects off a substance. Luster - Describes how shiny a substance is.
Answer:
The physical properties is hardness shape and color, I choose hardness because I have grabbed bowling balls before and they are very hard well there could be different types of bowling balls made of different things but I have never seen one or toughed a bowling ball that is not hard. Another physical property I chose for the bowling ball was shape, The reason I chose shape was because the bowling ball is circle, the actual name for a 3-D circle is sphere. The last physical property for a bowling ball is color because mostly all bowling balls have color for example the one in the picture it is red with a little bit of pink, there is many different bowling balls that have different color different hardness but NOT different shape. That is the physical properties of a bowling ball.

2. A race car travels a complete lap on a circular track of radius 500 m in 50 s. What is the
average velocity of the race car? (1 pt)
a. Zero
b. 100 m/s
C. 200 m/s
d. None of the above
3. In problem two. What would be the average speed? (2 pts)
1
Answer:
100m/s
Explanation:
velocity = displacement/time
The average velocity of the race car around the circular track in the given time is 62.8m/s.
Hence, option D) None of the above is the correct.
What is Average Velocity?Average velocity is simply the displacement of a particle or object over time. It is the rate of change of position of an object with respect to time.
It is expressed as;
Velocity = displacement / time
It can also be expressed as;
Velocity = circumference / time = 2πr / t
Given the data in the question;
Radius of the track r = 500mTime elapsed t = 50sAverage velocity V = ?To determine the average velocity, we substitute our values into the expression above.
V = 2πr / t
V = ( 2 × 3.14 × 500m ) / 50s
V = 3140m / 50s
V = 62.8m/s
The average velocity of the race car around the circular track in the given time is 62.8m/s.
Hence, option D) None of the above is the correct.

why a magnetic compass is used to determine direction
Answer:
compass is an instrument used for navigation and orientation that shows direction relative to the geographic cardinal directions (or points). Usually, a diagram called a compass rose shows the directions north, south, east, and west on the compass face as abbreviated initials.
This works because the Earth itself has a magnetic field which is similar to that of a bar magnet. The compass needle aligns with the Earth's magnetic field direction and points north-south.

A woman drives to her office 10 km away from her house at 9 am, and
reaches her office at 9:20 am. She stays in the office until 6 p.m, and
then returns home at 6:25 p.m. Which answer gives the correct
distance and displacement at 6:25 p.m.?
The displacement of the woman at 6:25 pm is zero (0) while her total distance at 6:25 pm is 20 km.
The given parameters;
distance between the woman's house and her office, d = 10 kmtime to reach her office = 20 minutestime to return to her house = 25 minutesDisplacement is defined as the change in the position of an object. It can be described as 'how far' an object is displaced from the initial position.
The first position of the woman, x₁ = 10 km to officeThe final position of the woman, x₂ = 10 km back homeThe woman's displacement = x₂ - x₁ = 10 km - 10 km = 0
Distance is the total path covered by an object during motion.
Total distance of the woman at 6:25 pm = 10 km + 10 km = 20 km
Thus, we can conclude that the displacement of the woman at 6:25 pm is zero (0) while her total distance at 6:25 pm is 20 km.

Determine how many Altuves you could travel in a day if you were moving at 45.000 mph all day. Altuve = 1.65 m
Answer:
The answer is below
Explanation:
Speed is the ratio of total distance traveled to the total time taken. It is given by the formula:
Speed = Distance / time taken
Given that the speed = The polynomial 45.000 mph.
In a day there are 24 hours, hence, the distance traveled is:
Speed = Distance / time taken
45 mph = Distance / 24 hours
Distance = 45 mph × 24 h = 1080 miles
But 1 mile = 1609.34 m
1080 miles = [tex]1080\ miles*\frac{1609.34 \ m}{1\ miles}=1738092\ m[/tex]
Given that Altuve = 1.65 m
Hence, the number of Altuve traveled = 1738092 m / 1.65 m = 1053389
1053389 Altuves was traveled
