In mathematics, an ellipse is a plane curve surrounding two focal points, such that for all points on the curve, the sum of the two distances to the focal points is a constant. As such, it generalizes a circle, which is the special type of ellipse in which the two focal points are the same.

Maybe they might use that math thing for Science.

Explanation:

youre welcome

Answer:

The time is likely between 40-80 seconds.

Explanation:

By swirling the mint, this is agitating and creating a higher frequency of collisions between the saliva particles and mint particles, increasing the rate of dissolution. Therefore, the time is likely to be less than the mint cut in half but probably more than the mint when it is in small pieces.

Answer:

Based on the given instructions, you need to calculate the expected kinetic energy (KE) at each velocity using the formula KE = mv^2, where m is the mass and v is the speed. The mass is given as 0.250 kg.

Table B: Calculation of Kinetic Energy (KE)

Table B: Calculation of Kinetic Energy (KE)

Speed (m/s)Mass (kg)KE (kg m^2/s^2)20.2500.50030.2500.75040.2501.00050.2501.25060.2501.500

To calculate the kinetic energy at each velocity, multiply the mass (0.250 kg) by the square of the velocity.

For example, when the speed of the bottle is 2 m/s: KE = (0.250 kg) * (2 m/s)^2 = 0.250 kg * 4 m^2/s^2 = 1.000 kg m^2/s^2

Perform similar calculations for the other velocities and record the results in Table B.

Answer:

Explanation:mass of the bottle in each case is M = 0.250 kg

now as per given speeds we can use the formula of kinetic energy to find it

1) when speed is 2 m/s

kinetic energy is given as

2) when speed is 3 m/s

kinetic energy is given as

3) when speed is 4 m/s

kinetic energy is given as

4) when speed is 5 m/s

kinetic energy is given as

5) when speed is 6 m/s

kinetic energy is given as

Let us go option by option :

1) Genes are located in chromosomes. TRUE

Chromosomes are in cell nucleus. A chromosome contains hundreds and thousands of genes. A normal have 23 pairs of chromosomes, and a total of 46.

2) Chromosomes are the in nucleus.

TRUE

Chromosome is structure found in nucleus of the cell. It is made up of protein and DNA.

3) A single Chromosome can contain hundreds of genes.

TRUE

single Chromosome can contain hundreds of tgenes.

4) All of the above

TRUE

As all the statements above are true. The correct option is 4.

Answer:

all of them are true

Explanation:

this is because chromosomes contain genetic materials and it is present in the nucleus.
Therefore, the correct option is 4) all of these are true

no problem

Answer:

39

Explanation:

Relative mass does not need to be calculated as it is listed on the periodic table. Potassium's relative atomic mass is around 39.

To prepare 250 mL of a D10/NS solution using D10W and a vial of NaCl 4 mEq/mL, you would need 9.6 mL of NaCl. Normal saline (NS) contains 154 mEq/L of sodium chloride (NaCl). To prepare 250 mL of NS, you would need 250 mL * (154 mEq/L) = 38500 mEq of NaCl. Since the vial of NaCl contains 4 mEq/mL, you would need 38500 mEq / (4 mEq/mL) = 9625 mL = 9.6 mL of NaCl. So the correct answer is b. 9.6ml.

chemical reaction, a process in which one or more substances, the reactants, are converted to one or more different substances, the products. Substances are either chemical elements or compounds. A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products.

Explanation:

MARK ME AS A BRAINLIST PLZ

The term which best describes the conversion of substances into different substances is a: chemical reaction.

A substance can be defined as a specific kind of matter that has definite or uniform properties.

In Science, there are two (2) main types of substance and these include:

A chemical reaction can be defined as a chemical process which involves the continuous conversion (transformation) and rearrangement of either the ionic, atomic or molecular structure of a substance, especially through the breakdown and formation of chemical bonds, in order to form (produce) a different substance.

In conclusion, a chemical reaction involves the conversion of substances into different substances.

Explanation:

Methane only has london dispersion forces since it is nonpolar. London dispersion force is the weakest intermolecular force, so the forces between its molecules will be weak. This leads to a low boiling point that is lower than room temperature, which makes it a gas at room temperature.

Explanation:

Answer:

There could be several possible reasons for a small gap between rails on a railway track, such as:

1. Expansion joints: Railways are designed to allow the tracks to expand and contract with changes in temperature. To accommodate this expansion, small gaps are left between the rail ends and filled with expansion joints or plates.

2. Wear and tear: Over time, the rails may experience wear and tear due to heavy loads, weather conditions, and other factors. As a result, small gaps can appear between the rails.

3. Maintenance: During maintenance activities, rail tracks may be adjusted or replaced, which could lead to small gaps between the rails.

4. Environmental factors: Environmental factors such as soil shifts, earthquakes or other natural disasters can also affect the alignment of the rails, leading to small gaps.

These are some of the possible reasons for a small gap between the rails on a railway track.

Answer:

The small gap left between the rails in a railway track is intentional and serves a specific purpose. This gap is known as the rail joint, and it allows for the expansion and contraction of the rails due to changes in temperature. When the temperature changes, the metal rails will expand or contract, and if they were joined together tightly, they could buckle or become deformed, which could be dangerous for trains passing over them. The rail joint allows the rails to move slightly and prevent damage to the track.

Additionally, the rail joint also allows for maintenance and repairs of the track. If there were no gap between the rails, it would be challenging to replace a damaged rail or perform routine maintenance, such as tightening bolts or lubricating joints. With the rail joint, maintenance personnel can easily access and work on the track.

Overall, the small gap left between the rails in a railway track is intentional and serves a crucial function in ensuring the safety and reliability of the track.

Answer:

observations (2), (3), and (4) provide strong evidence that a chemical reaction occurred.

Explanation:

Observations (2), (3), and (4) are evidence of a chemical reaction because a precipitate formed, energy was released (the bottom of the beaker felt warm), and bubbles were formed in the water. Observation (1) indicates a physical change, not a chemical reaction.
