What needed to be present in marine mud to form fossil fuels?
Answers
Carbon and Hydrogen.
Answer:
Mostly decaying organisms are needed to present in marine mud to form fossil fuels.
Explanation: When organisms and plants died and sank to the bottom of swamps and oceans, brown soil-like materials called peat are formed. Over millions of years, the peat became covered with sand, clay and other minerals and the peat is converted into layers of sedimentary rocks. After a long time, different type of fossil fuels are formed.

When the speed of the bottle is 2 m/s, the KE is kg m2/s2. When the speed of the bottle is 3 m/s, the KE is kg m2/s2. When the speed of the bottle is 4 m/s, the KE is kg m2/s2. When the speed of the bottle is 5 m/s, the KE is kg m2/s2. When the speed of the bottle is 6 m/s, the KE is kg m2/s2.
instructions
In this part of the experiment, you will be changing the speed of the bottle by dropping it from different heights. You will use the same mass, 0.250 kg, for each trial, so record this mass in Table B for each velocity. Then, calculate the expected kinetic energy (KE) at each velocity. Use the formula KE = mv2,
where m is the mass and v is the speed. Record your calculations in Table B of your Student Guide.
Answers
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

Answers
Answer:
Explanation:
Why is the use of the inquiry process (or scientific method) a practical way to approach science?
1. The inquiry process is a practical way to approach science because the inquiry process begins by asking questions and moving on from there.
2. In science it is important to investigate phenomena or certain subjects by posing questions that you would like to answer through the scientific method.
3. Therefore, the inquiry method is connected because to inquire on a subject requires raising questions which is an essential step in scientific discovery.
Why are scientific theories modified, but seldom discarded?
1. If a theory cannot explain new evidence or observations then the theory is revised or even thrown
out, but if the theory still explains a wide range of observations and evidence then it is revised
rather than discarded.
2. it will still hold some value as above as you learn more you tweak your hypothesis to fit the ever expanding amount of info and data you collect and assimilate
3. The only way they ever go away is if people stop working on them.

How does hot spot theory explain how the Hawaiian Islands formed? and what tools did you use to collect your data also describe the procedure that you followed to collect your data.
Answers
The hot spot theory explains how the Hawaiian Islands formed. According to this theory, the islands were created by a hot spot, which is an area of intense volcanic activity deep within the Earth's mantle. As the Pacific tectonic plate moves over the hot spot, it causes magma to rise to the surface, resulting in the formation of a new island. Over time, as the plate continues to move, new islands are formed while older islands move away from the hot spot and eventually erode.
To collect data about the formation of the Hawaiian Islands, scientists have used various tools and methods:
Seismic studies: Scientists have used seismometers to measure seismic waves and study the Earth's interior structure. By analyzing seismic data, they can identify the presence of a hot spot and understand its characteristics.Geochronology: Scientists have used radiometric dating techniques to determine the ages of rocks found on the islands. By dating volcanic rocks at different locations, they can create a timeline of island formation and track the movement of the hot spot.Bathymetry: Bathymetric surveys have been conducted using sonar technology to map the ocean floor around the Hawaiian Islands. This helps scientists understand the topography and the underwater volcanic activity associated with the hot spot.Core sampling: Scientists have collected core samples from the ocean floor to study the composition of volcanic rocks. By analyzing these samples, they can determine the chemical and mineralogical characteristics of the lava erupted from the hot spot.
Overall, the data collection procedure involves a combination of field surveys, laboratory analyses, and data interpretation. Scientists use a multidisciplinary approach to gather information from various sources and develop a comprehensive understanding of the Hawaiian Islands' formation.
I hope this explanation helps you understand how the hot spot theory explains the formation of the Hawaiian Islands and the tools and procedures used to collect relevant data.
