Are synthetic materials useful? Explain your answer.

Answer:

If an object is changing its velocity -whether by a constant amount or a varying amount

Explanation:

then it is an accelerating object. And an object with a constant velocity is not accelerating.

Answer:

the object can be accerleratting because the object supports it then later goes up for example a ball. if it supports that means its positive. if it has the weight like i mean by initially at rest. this means its negative. Hope this helps!

Some small volcanoes only erupt once in their lives,

while other volcanoes erupt multiple times. Kilaeua volcano in Hawaii, which has been erupting continuously since 1983, is the world's most active volcano. While some volcanoes erupt at regular intervals, there are always exceptions to the rule

Answer:

small volcano's only 1 time while big volcano's mutiple times

Answer:

First one is by the food we eat, we get fuel to be able to move and do work.

Second one is, the effect of speed on kinetic energy is the faster or slower something is going at, the more or less movement needed.

#1

We get the energy by the foods we take and respiration+ digestion plays key role in transformation

#2

This is because KE=1/2mv²

Answer:

The climate in the Tundra is cold with little to no rainfall and cold climate along with the frozen soil

Answer: The difference in the climatic and soil condition of the taiga and tundra makes it possible for some trees to grow in the taiga but not in the tundra.

Explanation: Tundra, has a harsher climate, worse soil conditions little precipitation, which makes it challenging for trees to develop and grow makes it difficult for trees to thrive. In contrast, the taiga has a more hospitable environment and soil conditions that allow tree growth. Long, harsh winters and brief, warm summers, along with fertile soil and comparatively high precipitation, are characteristics of the taiga biome.  As a result, taiga can support tree growth but tundra cannot.

Answer: the first paragraph is rain forest biome and the 2nd one is arctic tundra biome and finally the last paragraph is ocean or marine biome

Explanation:

rain forests have warm temperatures and include alot of animals and plants , artctic tundra biome includes cold temperatures ice stuff and all that and ocean or marine biome is pretty much just the ocean with seals , whales and marine life yk.

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

Explanation:

In the given graph, the Evolved Population is showing disruptive selection. Hence, the correct option is A. Disruptive selection.

Stabilizing selection is a form of natural selection where individuals with average phenotypes are more likely to survive and reproduce their number. In this selection, the population tends to maintain a stable phenotype. As shown in the graph, the population is maximum for the population having a moderate length of neck.

Disruptive selection is a type of natural selection where extreme phenotypes are preferred over average phenotypes, leading to an increase in genetic variation and the population becoming more diverse. In this type of selection, the population diverges into two or more distinct phenotypic groups. As shown in the graph, two ranges of the population are favored for having traits for extreme lengths of the neck.

Answer:

An acidic solution contains more hydroxide ions than hydroxide ions.

Explanation:

Answer:

An acidic solution contains more hydroxide ions than hydroxide ions.

Explanation:

Answer:

The answer is option A.3.3

The pH of acid is between 0-7 on pH scale while for base pH range is from 7-14.  pH is a unitless quantity. Therefore, the correct option is option A. the pOH of solution is 3.3.

pH is a measurement of amount of hydronium ion H₃O⁺ in a given sample. More the value of hydronium ion concentration, more will be the solution acidic.

On subtracting pH from 14, we get pOH which measures the concentration of hydroxide ion in a given solution. pH depend on the temperature. At room temperature pH scale is between 0 to 14. pH of neutral solution is 7.

Mathematically, the relation between pH and pOH can be given as

pH+ pOH=14

pH= 10.7

substituting all the given values in the above equation, we get

10.7+ pOH=14

pOH=14-10.7

        =3.3

Therefore, the correct option is option A. the pOH of solution is 3.3.
