Answer : The correct option is, Kinetic energy.
Explanation :
According to the kinetic energy, the kinetic energy is directly proportional to the mass of an object and the square of the velocity of an object.
The formula of kinetic energy is,
[tex]K.E=\frac{1}{2}\times m\times v^2[/tex]
where,
K.E = kinetic energy
m = mass of an object
v = velocity of an object
From this we conclude that there is a direct relationship between the kinetic energy and the mass of an object.
As per question, the reactant have a mass of 10 grams and contains energy 1000 J and the product have a mass of 5 grams and contains energy 500 J that means as the mass of an object decreases, the kinetic energy is also decreases.
Hence, the correct option is, Kinetic energy.

Why might a rubber raft burst if it is left in the sun on a summer day?
Answer: This is because of increase in air pressure inside the rubber raft.
Explanation:
According to Gay-Lussac's Law: 'The pressure of the gas at constant volume is directly proportional to the temperature in Kelvins'.
[tex]Pressure\propto Temperature[/tex](at constant Volume)
or [tex]\frac{Pressure}{Temperature}=constant[/tex]
So, when we left rubber raft in a sun on a summer day temperature of the air inside the rubber raft increases due to which pressure of an air inside the rubber raft also increases. And by this increase in pressure rubber raft bursts.
Rainwater will enter the ground at x if the ground is a) saturated and permeable
B) saturated and impermeable
C) unsaturated and permeable
D) unsaturated and impermeable
Final answer:
Rainwater enters the ground effectively when the soil is unsaturated and permeable, allowing the infiltration and percolation process to replenish groundwater sources.
Explanation:
The question 'Rainwater will enter the ground at x if the ground is a) saturated and permeable b) saturated and impermeable c) unsaturated and permeable d) unsaturated and impermeable' pertains to the concepts of groundwater recharge, infiltration, and the nature of soil permeability. Rainwater enters the ground through a process known as infiltration, which is significantly influenced by the soil's saturation level and its permeability. In this context, option C: unsaturated and permeable is the correct answer. This is because unsaturated soil indicates that there is room for more water in the soil's pore space, and permeability means the soil has pathways through which rainwater can move. When soil is unsaturated and permeable, it allows for effective infiltration and percolation of rainwater into deeper layers, eventually replenishing groundwater sources.

The 2004 Indian Ocean tsunami was caused by a major earthquake that originated below the earthquake epicenter, which is the point on the ocean's surface directly above the earthquake focus. The dashed lines on the map indicate the path of the tsunami's waves.
The correct answer is option C.
On December 26, 2004, a major earthquake occurred in the Indian Ocean, triggering a tsunami that resulted in the loss of thousands of lives. The earthquake originated below the earthquake epicenter, which is the point on the ocean's surface directly above the earthquake focus. The dashed lines on the map indicate the path of the tsunami's waves.
The earthquake epicenter is important because it is the point on the ocean's surface where the tsunami waves are generated. The waves radiate outward from the epicenter in all directions, with the largest waves occurring closest to the epicenter. The waves then travel across the ocean, decreasing in height as they move away from the epicenter.
The 2004 Indian Ocean tsunami was one of the deadliest tsunamis in recorded history, with an estimated 230,000 people killed. The tsunami waves reached heights of up to 30 meters (100 feet) in some areas, and caused widespread damage to coastal communities.
The 2004 tsunami was a reminder of the destructive power of tsunamis. It is important to be aware of the risks associated with tsunamis and to know what to do if a tsunami warning is issued.
Therefore, from the given options the correct one is C.

How is a watershed related to a river system
Answer:
The stream mouth is where a waterway streams into a bigger waterway, for example, another stream, a lake, or a sea. A watershed limit, likewise called a seepage isolate, marks the external most point of confinement of a watershed. A watershed is a tract of land depleted by a waterway and its tributaries.
A watershed, or a drainage basin, captures all the water from rain or snow fall, and directs it into a river or stream. A river system includes a main river and its tributaries. Together, the watershed and the river system form part of the hydrologic cycle, where a watershed feeds the river system, contributing to the overall flow of water on the earth's surface.
Explanation:A watershed is closely related to a river system as they are both integral parts of the hydrological cycle. A watershed, also known as a drainage basin, refers to an area of land where all of the water that falls as precipitation either drains off into the same place, typically a river, lake, or ocean. It captures the rainfall and snow melt and directs it into a single point, say a river or a stream.
On the other hand, a river system includes a river channel along with its tributaries (smaller streams or rivers that flow into the main river). The river system serves as the main transportation route of the water from the watershed. So, a watershed feeds a river system and together they contribute to the overall flow of water on earth's surface. For instance, the Amazon River system is fed by multiple small and large watersheds covering a large area of South America.

At 685 mmHg pressure and 50°C, a gas has a volume of 5.35 L. If the volume of the container decreases to 1.25 L, what is the amount of the pressure change?
Answer:
The amount of the pressure change is 2,246.8 mmHg.
Explanation:
In order to determine change in pressure we have to find the pressure of the gas when it occupied 1.25 L of volume.
So,to calculate the new pressure, we use the equation given by Boyle's law.
This law states that pressure is directly proportional to the volume of the gas at constant temperature.
The equation given by this law is:
[tex]P_1V_1=P_2V_2[/tex] (at constant temperature)
where,
[tex]P_1\text{ and }V_1[/tex] are initial pressure and volume.
[tex]P_2\text{ and }V_2[/tex] are final pressure and volume.
We are given:
[tex]P_1=685 mmHg\\V_1=5.35 L\\P_2=?\\V_2=1.25 L[/tex]
Putting values in above equation, we get:
[tex]685 mmHg\times 5.35 L=P_2\times 1.25 L[/tex]
[tex]P_2=\frac{685 mmHg\times 5.35 L}{1.25 L}=2931.8 mmHg[/tex]
The amount of the pressure change = [tex]P_2-P_1[/tex]
[tex]P_1-P_2=2931.8 mmHg-685 mmHg=2,246.8 mmHg[/tex]

Which kind of diagram shows changes in the three kinds of rocks over time? A. rock cycle B. stratification process C. crystallization rate D. temperature change
Answer:
A. rock cycle
Explanation:
Rock cycle shows the changes in the three kinds of rocks over time.
The rock cycle refers to the description of the geological processes that rocks go through to become igneous, sedimentary and metamorphic.
The cycle shows the time it takes for the different types of rocks to form and how this change is related to the water cycle and the way the tectonic plates move.
The rock cycle begins with the formation of igneous rock as the first stage.Igneous rocks can form when magma penetrates through cracks in existing rocks or by cooling lava from volcanic eruptions.
The formation of sedimentary rock as a second stage.Sedimentary rocks are formed by the consolidation of sediments that come from erosion.
That is, igneous rocks undergo different processes such as erosion, transport and weathering, which causes the rock to transform into small particles (sediments).
Over time, they are transformed due to the weight of the successive layers deposited and the action of water, forming rocks by a process called lithification.
The formation of metamorphic rock as a third stage.The metamorphic rocks suppose the alteration in solid state of rocks that are already consolidated in the earth's crust.
That is, sedimentary rocks are affected by the movement of the earth's crust related to the movement of tectonic plates and the formation of mountains.
Therefore, we can conclude that rock cycle shows the changes in the three kinds of rocks over time.

20. Archimedes' principle explains how an airplane flies. False
What is the gravityThe buoyant force is an upward force exerted by a fluid that opposes the weight of a partially or fully immersed object. It is caused by the difference in pressure between the top and bottom of the object. The pressure at the bottom of the object is greater than the pressure at the top because there is more fluid above it pushing down.
The magnitude of the buoyant force is equal to the weight of the fluid displaced by the object. This is known as Archimedes' principle. For example, if you place a ball in a cup of water, the buoyant force on the ball will be equal to the weight of the water that the ball displaces.

Plants perform photosynthesis and respiration. Dead plants are broken down and become part of the soil. Which of the following matter do plants help to cycle through ecosystems? Select one:
a. carbon only
b. carbon, oxygen, and nitrogen only
c. carbon and oxygen only d. carbon, oxygen, nitrogen, and water
Final answer:
The correct answer is "carbon, oxygen, nitrogen, and water". Plants are essential in cycling carbon, oxygen, nitrogen, and water through ecosystems via processes like photosynthesis, respiration, transpiration, and interactions with nitrogen-fixing bacteria.
Explanation:
Plants play a crucial role in cycling matter through ecosystems by participating in several biogeochemical cycles. During the photosynthesis process, they absorb carbon dioxide from the atmosphere and release oxygen, which is essential for the survival of most living organisms. Meanwhile, respiration in plants, animals, and decomposers returns carbon dioxide to the atmosphere. Plants are also involved in the water cycle through transpiration, and in the nitrogen cycle, through nitrogen-fixing bacteria that reside in the roots of certain plants like legumes. Therefore, plants help to cycle carbon, oxygen, nitrogen, and water through ecosystems.
