Which human activity contributes to the formation of acid rain

Answer: The processes that formed the rocks are deposition, cementation, and erosion because there was no chemical reaction (fizz)

Explanation:

because there was no chemical reaction (fizz)

Burning fossil fuels such as coal and gasoline

We know that burning fossil fuels, such as coal and gasoline, is a significant human activity that contributes to the formation of acid rain.

When fossil fuels are burned, they release pollutants into the atmosphere, including sulfur dioxide (SO2) and nitrogen oxides (NOx).

These pollutants can react with water, oxygen, and other chemicals in the atmosphere to form sulfuric acid (H2SO4) and nitric acid (HNO3), which are major components of acid rain.

Therefore the correct answer is

Burning fossil fuels such as coal and gasoline

Answer: They both wear away material

Explanation:

Answer: Mechanical and chemical weathering are similar in that they both break down rocks. However, mechanical weathering physically breaks rocks into smaller pieces without changing their chemical composition, while chemical weathering changes the chemical composition of rocks through chemical reactions.

The volume of the key is 0.8 mL.

An object that floats on water will displace its own volume. In the same vein, an object that sinks in water will displace its own volume.

Thus, in order to find the volume of an object that sinks in water, measure the volume of water that it displaces.

In this case, the water displaced by the key was measured 3 times. The average of the 3 readings will give the volume of the key.

Volume of the key = 0.7 + 0.8 + 0.9/3 = 0.8 mL

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

Five wave parameters are defined and measured: the time, the frequency, the amplitude, the wavelength, and the speed. The wave length is the time it takes to pass a full phase. The frequency is just the opposite; it's the number of wave cycles that have been completed in a second.

Lets give a wave of water as an example. Its wavelength is the distance from crest to crest or from trough to trough. The wavelength can also be thought of as the distance a wave has traveled after one complete cycle—or one period. The time for one complete up-and-down motion is the simple water wave’s period T. In the figure, the wave itself moves to the right with a wave velocity vw. Its amplitude X is the distance between the resting position and the maximum displacement—either the crest or the trough—of the wave.

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.
