explain why so much thermal energy is released in a chain reaction
Answer:
It is the chain reaction process that is used in reactors and nuclear weapons to generate a large number of fissions. In a reactor, the propagation of fissions takes place in a controlled manner, in a nuclear weapon in an uncontrolled, explosive manner.
The products of nuclear fission are usually accompanied by two to three secondary, free neutrons which can be absorbed later by other fissile nuclei. These absorptions in turn lead to further fissions, then to the production of other neutrons etc ..., a process commonly called chain reaction.

explain how siphon works with atmospheric pressure?
Answer:
A siphon is a tube that allows liquid to travel upward, above the surface of the origin reservoir, then downwards to a lower level without using a pump. When a certain amount of water moves over the bend in the siphon, gravity pulls it down on the longer leg lowers the atmospheric pressure in the bend of the siphon.

The photo shows a sea urchin embryo. A sea urchin is a multicellular organism. جام Which two processes occur as the sea urchin embryo grows? A. The embryo's cells grow larger in size. B. The amount of DNA in the embryo's body cells decreases. C. The total number of cells in the embryo's body decreases. D. The embryo's cells take in water and nutrients. SUBMIT
Answer:
d and a
Explanation:
The embryo's cells grow larger in size, and the embryo's cells take in water and nutrients. The correct options are A and D.
The two processes that occur when the sea urchin embryo matures, according to the information presented, are:
The embryo's cells grow in size: During the embryo's growth and development, individual cells divide and grow in size, contributing to the organism's total growth.
The embryo's cells actively take in water and nutrients from the surrounding environment: As the embryo grows, its cells actively take in water and nutrients from the surrounding environment to support metabolic processes and offer the essential resources for growth and development.
Thus, choices A and D represent the proper processes that occur while the sea urchin embryo develops.

Why do larger stars life a shortter life?
Answer:
A star's life expectancy depends on its mass. Generally, the more massive the star, the faster it burns up its fuel supply, and the shorter its life. ... A star with a mass like the Sun, on the other hand, can continue fusing hydrogen for about 10 billion years.
Explain this phase diagram by relating what you know about temperature, states of matter and
pressure.
Answer:
See explanation
Explanation:
The vertical axis corresponds to the pressure of a substance, while the horizontal axis corresponds to the temperature. The solid is the substance which contains particles of strong intermolecular force and compaction, typically ionic at a certain temperature, the liquid is the substance which contains relatively compact molecules, however lacks a particular arrangement. The gaseous substance is caused by particles with weak intermolecular forces, causing particle movement and collision with no arrangement whatsoever. The triple point as shown in the diagram, is the phrase on a diagram where each substance: solid, liquid and gas coexist. The critical point is the phase at which the/a substance is indistinguishable between liquid and gaseous states. A substance or elements state is highly dependent on its environment and it’s temperature, of which ultimately affects its kinetic energy within its particles. This is what the graph portrays and represents.

Question pictured below
When a person speaks, a sound intensity is generated that is 600 times greater than when the person whispers. What is the difference in decibels between the sound level when the person speaks compared to when she whispers
Answer:
Originally : Level = log I / I0
Currently: Level = 10 log I / I0
Level = 10 log 600 = 10 * 2.78 = 27.8
Note the term 1 bel = 10 decibels

MY PAPER IS DUE IN AN HOUR!!!
Your challenge- Write a paper on how to build, construct, and engineer a faster roller coaster. You essay must contain 5 paragraphs minimum. Each paragraph must be 3 sentences minimum.
Potential energy, Kinetic energy, Thermal energy and friction, speed, velocity, and acceleration, and the law of conservation of energy must be the main ideas of your paragraphs
Answer:
Your kinetic energy is always proportional to the square of your speed,
no matter whether you're on a bicycle, a roller coaster, or a baby carriage.
The faster you're moving, the more kinetic energy you have.
Your potential energy doesn't depend on speed at all, only on height.
On a roller coaster, the minimum speeds are usually at the top of a hill
or a loop, so the potential energy would generally correspond to the
slowest speeds. But again, that's not because of the speed. It's because
of the height.

Imagine that you are going to make an exercise routine. If your goal was to develop your health rather than one specific improvement, what should be in your plan?
A.
a focus on the benefits of stretching
B.
a variety of aerobic and anaerobic exercises
C.
a single exercise with increasing intensity
D.
an exercise that you have never tried before
PLEASE NO LINKS
Answer:
c
Explanation:
If the goal of the exercise routine is to develop overall health rather than focusing on one specific improvement, a well-rounded approach that addresses various aspects of fitness would be ideal.
This would involve a combination of different types of exercises to promote cardiovascular health, muscular strength, flexibility, and overall well-being. From the given options, the best choices would be:
B. A variety of aerobic and anaerobic exercises: This option is important because it incorporates both cardiovascular exercises (aerobic) and strength-building exercises (anaerobic), ensuring a balanced approach to fitness.
A. A focus on the benefits of stretching: Stretching is important for maintaining flexibility and preventing injuries. Incorporating stretching exercises, such as static and dynamic stretches, can contribute to overall health and mobility.
D. An exercise that you have never tried before: While not as essential as the first two options, trying new exercises can add variety and excitement to your routine. It can also engage different muscle groups and challenge your body in new ways.
C. A single exercise with increasing intensity: While progressively increasing the intensity of a single exercise can be part of a fitness plan, focusing solely on a single exercise may not provide the diverse benefits that a combination of exercises can offer. Variety is key to a well-rounded fitness routine.
