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.

Answers

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.

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).

Answers

Answer:

0.42s

Explanation:

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

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.

Answers

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

A bus travels 210 km south along a straight

path with an average velocity of 85 km/h to

the south. The bus stops for 25 min, then it

travels 230 km south with an average velocity

of 73 km/h to the south.

How long does the total trip last?

Answer in units of h.

Answers

Answer:

6.04 hr

Explanation:

The bus first travels a distance of 210 km south at an average velocity of 85 km/h. The time, t it takes to cover this distance is gotten from d = vt and t = d/v where d = distance and v = velocity.

So, t = 210 km/85 km/h = 2.47 h

The bus then stops for 25 min. We convert 25 min to hours by dividing by 60.

So 25 min = 25/60 hr = 5/12 h = 0.42 h

The bus then travels 230 km south at an average velocity of 73 km/h.

The time it takes to cover this distance is t = 230 km/73 km/h = 3.15 h

So, the total time for the trip is the sum of each individual time, which is 2.47 h + 0.42 h + 3.15 h = 6.04 hr

So, it takes 6.04 hr for  the total trip

Use the picture to answer the question. Name at least three physical properties of the bowling ball. ​

Answers

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.

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.?

Answers

The distance is 0 because she is where she started the displacement is 10km as that is the total distance away she traveled.

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 minutes

Displacement 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 home

The 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.

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.

Determine how many Altuves you could travel in a day if you were moving at 45.000 mph all day. Altuve = 1.65 m

Answers

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

A student lefts a bouncy ball to 1.2m, then releases the ball. The ball bounces back up to 0.86m. Construct an explanation as to what happened to the energy.

Answers

Answer:

the decrease in energy is due to a transformational in internal energy of the body in the rebound.

Explanation:

For this exercise we can calculate the initial and final mechanical energy

        Em₀ = U = m g y₁

        [tex]Em_{f}[/tex] = U = m g y₂

we look for the variation of the energy

       ΔEm = Em_{f} - Em₀

       ΔEm = m g (y_{f} -y₀)

       ΔEm = m g (0.86 -1.2)

       ΔEm = -3.332 m

We can see that there is a decrease in mechanical energy, this is transformed into internal energy of the ball during the impact with the ground, this energy can be formed by several factors such as a part of the friction with the surface, an increase in body temperature or a deformation of the body; there may be a contribution from several of these factors.

In conclusion the decrease in energy is due to a transformational in internal energy of the body in the rebound.

Answer:

Please find the answer in the explanation

Explanation:

Given that a student lefts a bouncy ball to 1.2m, then releases the ball. The ball bounces back up to 0.86m. To Construct an explanation as to what happened to the energy, let first consider the difference in the two height of the ball.

The initial height = 1.2 metres

Final height = 0.86 metres

There is a loss in elastic potential energy of the ball. And the loss energy is due to the difference in the height of the ball under the gravity.

The loss in elastic potential energy is being converted to the gravitational potential energy.

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?

Answers

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
