Answer:

Exothermic Reaction.

Explanation:

An exothermic reaction is a chemical reaction that releases energy in the form of light or heat. The burning of the candle is an exothermic reaction. Endothermic reactions - Heat is absorbed, like the Photosynthesis process.

The statement that is incorrect is: The time interval between conditions of maximum potential energy is one period.

The time interval between conditions of maximum potential energy is not always one period. The period of a pendulum is the time it takes for the pendulum to complete one full cycle of motion, which is determined by the length of the pendulum and the acceleration due to gravity. The time interval between conditions of maximum potential energy depends on the initial conditions of the pendulum, such as the initial angle and the initial velocity. If the initial angle or the initial velocity is changed, then the time interval between conditions of maximum potential energy will change as well.

Friction can affect wooden structures in several ways such as wear ant tear, sticking, warping, and heat build up.

Abrasion and wear: Over time, friction between two hardwood surfaces might lead to these problems. Foot traffic can cause the wood to gradually erode, which is a worry for wooden constructions like flooring.

Friction can occasionally lead wooden surfaces to adhere to one another. Furniture made of wood may experience this issue, making it challenging to open or close drawers or doors because of friction.

Warping: In wooden buildings, friction can also cause warping. Because heat from friction can cause the wood to expand or contract, this is the case. This may cause the wood to bend, bow, or twist over time.

Heat buildup: Friction can occasionally produce enough heat to start a fire. This is especially problematic for wooden objects like tools or machines that experience frequent or severe friction.

Alpha decay occurs when a heavy nucleus undergoes spontaneous decay by the emission of an alpha particle, i.e., a helium nucleus. Despite being tightly bound in the nucleus by the strong nuclear force, the nucleons making up the alpha particle escape the nucleus because of the large energy released in the process.

Alpha decay occurs mainly in heavy nuclei, which are held together by a large number of protons and neutrons. These heavy nuclei tend to be unstable and can undergo spontaneous decay to become more stable. The process of alpha decay can be explained by quantum mechanics, which allows the alpha particle to tunnel through the strong nuclear force barrier and escape the nucleus.

The half-life of the parent nucleus determines the rate of alpha decay.(b) Half-lives of U-235 and U-238The half-life of U-235 is about 700 million years, while that of U-238 is about 4.5 billion years. These isotopes are used in nuclear reactors to produce energy. U-235 is used as a fuel in nuclear reactors, while U-238 is used to produce plutonium, which can be used as a fuel in nuclear reactors. The longer half-life of U-238 means that it is more abundant than U-235, but U-235 is more fissile and can sustain a chain reaction.

Strong evidence for the existence of dark matter comes from observations of clusters of galaxies.

Observations of clusters of galaxies provide compelling evidence for the presence of dark matter. When studying the motion of galaxies within clusters, it becomes apparent that the visible matter alone cannot account for the observed gravitational effects. The gravitational pull required to hold these galaxies together and explain their motions is significantly greater than what can be accounted for by the visible matter, such as stars and gas clouds. This suggests the presence of additional mass in the form of dark matter, which does not interact with light and thus cannot be directly observed.

While our solar system and the center of the Milky Way have also been subjects of study in the search for dark matter, the evidence from observations of clusters of galaxies is particularly strong. The large-scale distribution of dark matter within clusters, along with the observed gravitational lensing effects caused by dark matter, provide strong support for its existence.

Suppose each bulb has resistance r . with bulb c in place, bulbs b and c are in blank and have equivalent resistance blank. This implies that if we remove bulb C and replace it with an identical bulb, the resistance of the circuit will remain the same

Suppose each bulb has resistance r. When bulb C is in place, bulbs B and C are in series and have an equivalent resistance of 2r. In a series circuit, the total resistance is the sum of the individual resistances. When bulbs B and C are in series, the current flowing through them is the same. Thus, the total resistance is the sum of their resistances, which in this case is r + r = 2r. In a series circuit, the same current flows through each component. This means that if bulb C has resistance r and is in series with bulb B, the current passing through bulb B is also the same. The voltage across the bulbs is divided between them based on their resistances, and since they have the same resistance r, they receive equal voltage. So, with bulb C in place, bulbs B and C are connected in series and have an equivalent resistance of 2r. This implies that if we remove bulb C and replace it with an identical bulb, the resistance of the circuit will remain the same. Series circuits allow the current to flow through each component one after another, while the voltage divides between them.

A \(2.0\ cm \times 2.0\ cm \times 6.0\ cm\) block floats in water with its long axis vertical. The length of the block above water is \(3.0\ cm\) , the block's mass density \(833.33\ kg/m^3\).

Density is a fundamental physical property that measures how much mass is contained in a given volume of a substance. In other words, it quantifies how tightly packed the particles of a material are within a specific amount of space.

Given information:

The volume of the submerged portion of the block in the water \((V_{in water}) = 2 cm \times 2 cm \times 5 cm = 20 cm^3\)

Density of water \((d_{water}) = 1000\ kg/m^3\)

The volume of the entire block \((V_{block}) = 2 cm \times 2 cm \times 6 cm = 24\ cm^3\)

Acceleration due to gravity \((g) = 9.8\ m/s²\)

Using the principle of equilibrium for buoyant forces:

\(V_{in water} \times d_{water} \times g = V_{block} \times d_{wood} \times g\)

Solving for the density of wood \((d_{wood})\):

\(d_{wood} = (V_{in water} \times d_{water}) / V_{block}\\d_{wood} = (20 \times 1000 ) / 24 \\d_{wood} = 833.33\ kg/m^3\)

We want to see if the Trust SSC can archive a higher maximum speed.

Remember the second Newton's law:

Force = mass*acceleration.

And acceleration is the rate of change of the velocity.

Assuming the mass of the Trust SSC does not change, increasing the force would mean that we increase the acceleration, and thus, larger velocities can be reached.

Now there are some problems.

How we do increase the force?.

It is hard to ve precise, mostly because we don't really know how the system works, we just got some given random data that we can't use without context.

Another thing we need to remember, this velocity is measured in only one mile. So because we have a fixed distance to measure it, we only can get larger velocities by increasing the acceleration.

And to increase the acceleration we can increase the force, as discussed, or, decrease the mass.

How to decrease the mass? Using lighter materials.

Now let's see an example on how decreasing the mass would affect the acceleration.

Then an aproximate force is given by:

F = 10,700kg*20.8 m/s^2 = 222,560 N

Now, if we decrease the mass a little bit, for example to 10,000kg, and we do not change the force, the new acceleration will be given by:

10,000kg*a = 222,560 N

a = (222,560 N)/(10,000kg) = 22.3 m/s^2

So decreasing the mass a little, increases the acceleration, which would make a larger maximum velocity.

Concluding, there are two ways of increasing the maximum velocity:

Increasing the force.
