Answer: Experimental design means creating a set of procedures to test a hypothesis. A good experimental design requires a strong understanding of the system you are studying. By first considering the variables and how they are related ( Step 1 ), you can make predictions that are specific and testable

Explanation:

A hypothesis (plural hypotheses) is a proposed explanation for a phenomenon. For a hypothesis to be a scientific hypothesis, the scientific method requires that one can test it. Scientists generally base scientific hypotheses on previous observations that cannot satisfactorily be explained with the available scientific theories. Even though the words "hypothesis" and "theory" are often used interchangeably, a scientific hypothesis is not the same as a scientific theory. A working hypothesis is a provisionally accepted hypothesis proposed for further research, in a process beginning with an educated guess or thought.

A fusion reaction is a nuclear process in which the liberated energy a result of the conversion of mass energy.

In a fusion reaction, light nuclei merge to form a single heavier nucleus. The procedure releases electricity because the full mass of the resulting single nucleus is much less than the mass of the 2 original nuclei. The leftover mass becomes power.

Nuclear fusion is a response wherein extra atomic nuclei are blended to form one or greater distinct atomic nuclei and subatomic particles. The difference in mass among the reactants and products is manifested as both the release or absorption of power.

Commonly, fusion reaction isn't always viable because the strongly repulsive electrostatic forces between the definitely charged nuclei save you them from getting close sufficient together to collide and for fusion to arise.

Explanation:

So since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force, so as the mass of either object increases, the force of gravitational attraction between them also increases.

When Tarzan is hanging on the vine, the tension force in the vine is equal to his weight. First, we need to calculate his weight using the formula: Weight = mass × gravity. Assuming gravity is approximately 9.81 m/s²:
Weight = 78 kg × 9.81 m/s² = 765 N So when Tarzan is hanging still, the magnitude of the tension force in the vine is 765 N.

Next, Tarzan decides to use the vine to cross a creek. As he swings across the creek, he reaches a speed of 9 m/s at the lowest point. At this point, the tension force in the vine will have two components: one due to his weight (765 N) and another due to the centripetal force as he swings through the arc. To find the centripetal force, we can use the formula: Centripetal Force = mass × (velocity² / radius). We know that the length of the vine is 7 m, which is the radius.
Centripetal Force = 78 kg × (9 m/s)² / 7 m = 78 kg × 81 m²/s² / 7 m = 936 N
Now, we can find the total tension force in the vine by combining the centripetal force and his weight. The tension force acts diagonally, so we need to use the Pythagorean theorem:
Tension Force = √(Weight² + Centripetal Force²) = √(765 N² + 936 N²) ≈ 1208 N
So when Tarzan is swinging across the creek and reaches the middle (lowest point) at 9 m/s, the magnitude of the tension force in the vine is approximately 1208 N.

764.4 N is the magnitude of the tension force in the strength of vine and 451.3 N  is the magnitude of the tension force in the vine swing across the creek.

In the first scenario, we can calculate the magnitude of the tension force in the vine using the formula F=ma, where F is the force, m is the mass, and a is the acceleration. Since Tarzan is hanging on the vine without any movement, the acceleration is zero. Thus, the tension force in the vine is equal to the weight of Tarzan, which can be calculated as follows:
Weight = mass x gravitational acceleration
Weight = 78 kg x 9.8 m/s²
Weight = 764.4 N
Therefore, the magnitude of the tension force in the vine when Tarzan is testing the strength of the vine is approximately 764.4 N.
In the second scenario, we need to use the conservation of energy principle to calculate the tension force in the vine. At the highest point of the swing, all of the potential energy is converted into kinetic energy. At the lowest point, all of the potential energy is zero and all of the energy is kinetic. Therefore, the kinetic energy at the highest point is equal to the kinetic energy at the lowest point. The formula for kinetic energy is KE = (1/2)mv², where KE is the kinetic energy, m is the mass, and v is the velocity.
Using this formula, we can calculate the kinetic energy of Tarzan at the lowest point:
KE = (1/2) x 78 kg x (9 m/s)²
KE = 3159 J
Since the kinetic energy at the highest point is also 3159 J, we can use this value to find the tension force in the vine:
KE = (1/2)mv² = tension force x distance
3159 J = tension force x 7 m
tension force = 451.3 N
Therefore, the magnitude of the tension force in the vine when Tarzan swings across the creek is approximately 451.3 N.

The path of the Celestial Equator in a northern observer's local sky can be described as rising in the East, crossing the meridian in the North, and setting in the West.

The Celestial Equator is an imaginary circle on the celestial sphere, directly above the Earth's equator. It is an extension of the Earth's equator into space. The path of the Celestial Equator appears to move across the sky due to the rotation of the Earth.

For a northern observer, the Celestial Equator rises in the East. As the Earth rotates, the Celestial Equator crosses the observer's meridian, which is an imaginary line running from north to south through the observer's zenith (the point directly overhead). This crossing occurs in the northern part of the sky. Finally, as the Earth continues to rotate, the Celestial Equator sets in the West.

It's important to note that the Celestial Equator is fixed with respect to the stars, and its path remains the same throughout the night.

Based on the Second Law of Newton, if the net force were doubled, a system acceleration would also doubled.

The Second law of Newton stated that when a force is working on a system, the system's acceleration will depend on the amount of force and the total mass of the system. Newton's second law can be formulated as:

F = m.a

where:

F = net force working on the system

m = mass of the system

a = system's acceleration

If the force working on a system is doubled and the system's mass remains constant, the system acceleration would:

F = m.a

F' = 2F

F' = m.a'

2F = m.a'

2(m.a) = m.a'

Plate tectonics, the rock cycle, and surface processes interact to create, concentrate, and distribute mineral resources. Understanding these processes is crucial for identifying and extracting valuable minerals for human use.

Plate tectonics, the rock cycle, and surface processes such as weathering and erosion play important roles in the availability of mineral resources for human extraction and use. Here's how these processes contribute:

Plate Tectonics: Plate tectonics is the theory that explains the movement of Earth's lithospheric plates. It influences the distribution of mineral resources through several mechanisms:

a. Subduction Zones: When one tectonic plate is subducted beneath another, it creates intense heat and pressure, causing rocks to melt and form magma chambers. This process can generate large deposits of minerals, including precious metals, such as gold and silver, as well as base metals like copper and lead.

b. Divergent Boundaries: At divergent plate boundaries, such as mid-oceanic ridges, magma rises to the surface, cools, and solidifies, forming new crust. These areas often contain valuable mineral resources, including iron, manganese, and hydrothermal vents that can host valuable metal deposits.

c. Transform Boundaries: Transform plate boundaries, where plates slide past each other, can create fault zones. These fault zones can act as conduits for hydrothermal fluids, which can deposit minerals like copper, zinc, and lead.

Rock Cycle: The rock cycle is a continuous process that describes how rocks are formed, weathered, and transformed over time. It contributes to the availability of mineral resources in the following ways:

a. Igneous Processes: Igneous rocks, formed from the solidification of magma or lava, can host valuable mineral deposits. For example, granite and pegmatite rocks can contain minerals such as quartz, feldspar, and mica, while basaltic rocks can contain minerals like iron and magnesium.

b. Metamorphic Processes: Heat and pressure during the metamorphic process can cause minerals to recrystallize and concentrate, leading to the formation of economically significant mineral deposits. Examples include metamorphic deposits of asbestos, talc, and graphite.

c. Sedimentary Processes: Sedimentary rocks are formed from the accumulation of sediments, which may contain mineral grains eroded from existing rocks. Sedimentary deposits are important for resources like coal, oil, natural gas, and mineral sands (e.g., titanium, zircon).

Surface Processes (Weathering and Erosion): Surface processes, including weathering and erosion, can influence the availability and concentration of mineral resources:

a. Weathering: Weathering breaks down rocks into smaller particles, releasing minerals from their original host rocks. Through chemical weathering, certain minerals can be concentrated or leached, leading to the formation of economically viable deposits. For instance, weathering of sulfide minerals can generate ore bodies containing valuable metals like copper, zinc, and nickel.

b. Erosion and Sedimentation: Erosion transports weathered materials and deposits them in new locations, potentially concentrating mineral resources. Sedimentation in riverbeds, deltas, and ocean basins can create deposits of heavy minerals like gold, diamonds, and rare earth elements.

Overall, plate tectonics, the rock cycle, and surface processes interact to create, concentrate, and distribute mineral resources. Understanding these processes is crucial for identifying and extracting valuable minerals for human use.

The net direction on the cart, if a person pulls on a cart to the right with a force of 10n and a second person pulls to the left with a force of 3n, is 7n to the right.

The net force direction can be determined by finding the net vector sum of the forces acting on it.

Since the first person pulled the cart to the right with a force of 10n,

Assuming the right direction as positive, this force can be represented as a vector ⇒(+)10n

Similarly, as the second person pulls the cart to the left, the force can be represented as a vector ⇒ (-)3n,

∴ Net force = Net vector sum of the forces

                   =(+10n) + (-3n)

⇒Net force = +7n
