During capillary action, the water will rise higher in a narrower tube or channel with a smaller diameter.

This is because the smaller diameter creates a greater surface tension, which pulls the water upward against gravity. Additionally, a surface with a higher degree of attraction to the water molecules will also enhance capillary action, allowing the water to rise higher.
                                     This is because the adhesive forces between the water molecules and the tube's surface, as well as the cohesive forces between the water molecules themselves, are stronger in smaller diameter tubes, leading to a greater capillary rise.

When two materials that are in contact have the same temperature, the materials are said to be in thermal equilibrium.

Thermal equilibrium is a state in which there is no net flow of heat between two objects in contact. In this state, the temperature of the objects does not change over time, as there is no temperature gradient between them. This is a fundamental principle of thermodynamics, and it is the basis for the design and operation of many thermal systems.

The concept of thermal equilibrium is also important in fields such as materials science, engineering, and physics, where it is used to describe the behavior of materials and their interactions with the environment.

The factor by which the displacement will change is 3.0, and the answer is option b.

The displacement of a spring's lower end is directly proportional to the weight suspended from it. This relationship is expressed by Hooke's law, which states that the displacement (x) of a spring is equal to the force (F) applied to it divided by its spring constant (k), or x = F/k.
In this scenario, we are tripling the weight suspended vertically from a coil spring. According to Hooke's law, if the weight is tripled, the force applied to the spring will also triple. Since the displacement is directly proportional to the force, we can say that the displacement will also triple.
Therefore, the factor by which the displacement will change is 3.0, and the answer is option b.

Nuclear fission is used by all nuclear power plants, and uranium atoms are typically used in nuclear power plants.In nuclear fission, an neutron splits an atom of uranium by slamming against it; two neutrons are created in the process.

A U-235 nucleus immediately splits in half after taking in an additional neutron.Fission is the term for this action (see diagram below).A split U-235 nucleus releases two to three neutrons each time it divides.As a result, starting a chain reaction is possible.

Continuous fission was achieved as more neutrons are successively emitted.Fission-generated neutrons have tremendous energy and move very swiftly.The procedure of moderation is used in most reactors to slow down these so-called rapid neutrons because they do not promote fission as effectively as slower-moving ones do.

The required average speed to reach the school will be 2.5 meters per second.

According to the question,

School is still 1500m away and it starts in 10 minutes. We need to determine at what average speed you need to travel to reach the school on time.

What is speed?

Speed is defined as when an object is subjected to move, the distance covered by the object in a certain time interval is the speed of that particular object.

Here it is given,

Distance = 1500m

Time = 10 minutes or 10×60(seconds) = 600 seconds

Speed = distance/time

Speed = 1500/600

Speed = 2.5 meters per second

Thus, the average speed needed to reach the school at a distance of 1500m in 10 minutes will be 2.5 meters per second.

This method of transferring charge by rubbing objects is charging by friction.

Charging is defined as the phenomenon of transferring charge between two objects by supplying electrons between the objects.

Here,

The student done an experiment of rubbing a glass rod with a piece of silk and as a result, static charge is produced.

This is because, when the two objects are rubbed against each other, there occurs a friction between them. During this process, the glass rod that has free electrons that are freely bound to it will transfer its electrons to the piece of silk cloth. As a result, the glass rod will lose electrons and will have an electron deficiency, that means the glass rod becomes positively charged. At the same time, the silk cloth will acquire the electrons and the piece of silk becomes negatively charged.

This phenomenon of transferring charge between two objects when they are rubbed against each other is called charging by friction.

The concentration of [OH] in the basic solution is 0.177 mol/L.

To find the concentration of [OH] in the basic solution, we first need to use the balanced chemical equation for the neutralization reaction between HCl and OH-:

HCl + OH- -> H2O

We can see from the equation that 1 mole of HCl reacts with 1 mole of OH-. Therefore, the number of moles of HCl used in the reaction is equal to the number of moles of OH- in the basic solution.

First, let's calculate the number of moles of HCl used:

n(HCl) = c(HCl) x V(HCl)
n(HCl) = 0.150 mol/L x 0.0295 L
n(HCl) = 0.004425 mol

Since 1 mole of HCl reacts with 1 mole of OH-, the number of moles of OH- in the basic solution is also 0.004425 mol.

Next, we can use the volume and number of moles of OH- to calculate its concentration:

c(OH-) = n(OH-) / V(OH-)
c(OH-) = 0.004425 mol / 0.0250 L
c(OH-) = 0.177 mol/L

Therefore, the concentration of [OH] in the basic solution is 0.177 mol/L.

Answer:

a) The net momentum of the bullet-block system before the collision is 25 kilogram-meters per second.

b) The initial translational kinetic energy of the bullet before the collision is 625 joules.

c) The final speed of the bullet-block system after the collision is 7.143 meters per second.

d) The total energy of the bullet-block system after the collision is 89.289 joules.

e) 89.289 joules must be done to stop the bullet-block system.

f) The bullet-block system will travel 13.007 meters before stopping.

Explanation:

a) Since no external forces are applied on the system defined by the bullet and the block, then the net momentum is conserved and can be calculated by  the initial momentum of the bullet:

\(p = m\cdot v_{o}\) (1)

Where:

\(p\) - Net momentum, in kilogram-meters per second.

\(m\) - Mass of the bullet, in kilograms.

\(v_{o}\) - Initial speed of the bullet, in meters per second.

If we know that \(m = 0.5\,kg\) and \(v_{o} = 50\,\frac{m}{s}\), then the net momentum of the bullet-block system before the collision is:

\(p = (0.5\,kg)\cdot \left(50\,\frac{m}{s} \right)\)

\(p = 25\,\frac{kg\cdot m}{s}\)

The net momentum of the bullet-block system before the collision is 25 kilogram-meters per second.

b) The total energy of the bullet before the collision is its initial translational kinetic energy (\(K\)), in joules:

\(K = \frac{1}{2}\cdot m \cdot v_{o}^{2}\) (2)

\(K = \frac{1}{2}\cdot (0.5\,kg)\cdot \left(50\,\frac{m}{s} \right)^{2}\)

\(K = 625\,J\)

The initial translational kinetic energy of the bullet before the collision is 625 joules.

c) Both the bullet and the block experiments a complete inelastic collision, then the final speed of the bullet-block system is calculated solely by the Principle of Momentum Conservation:

\(v_{f} = \frac{m\cdot v_{o}}{m+M}\) (3)

Where:

\(v_{f}\) - Final speed, in meters per second.

\(M\) - Mass of the block, in kilograms.

If we know that \(m = 0.5\,kg\), \(v_{o} = 50\,\frac{m}{s}\) and \(M = 3\,kg\), then the final speed of the bullet-block system is:

\(v_{f} = \left(\frac{0.5\,kg}{0.5\,kg + 3\,kg} \right)\cdot \left(50\,\frac{m}{s} \right)\)

\(v_{f} = 7.143\,\frac{m}{s}\)

The final speed of the bullet-block system after the collision is 7.143 meters per second.

d) The total energy of the bullet-block system after the collision is the translational kinetic energy of the system (\(K\)), in joules, is:

\(K = \frac{1}{2}\cdot (m + M)\cdot v_{f}^{2}\) (4)

\(K = \frac{1}{2}\cdot (0.5\,kg + 3\,kg)\cdot \left(7.143\,\frac{m}{s} \right)^{2}\)

\(K = 89.289\,J\)

The total energy of the bullet-block system after the collision is 89.289 joules.

e) By Work-Energy Theorem, magnitude of the work done by friction must be equal to the magnitude of the translational kinetic energy of the system. Hence, 89.289 joules must be done to stop the bullet-block system.

f) The maximum travelled distance of the bullet-block after the collision can be determined by means of Work-Energy Theorem and definition of work:

\(W = \mu_{k}\cdot (m+M)\cdot g\cdot s\) (5)

Where:

\(W\) - Work done by friction, in joules.

\(g\) - Gravitational acceleration, in meters per square second.

\(s\) - Travelled distance, in meters.

\(\mu_{k}\) - Kinetic coefficient of friction, no unit.

If we know that \(m = 0.5\,kg\), \(M = 3\,kg\), \(\mu_{k} = 0.2\), \(g = 9.807\,\frac{m}{s^{2}}\) and \(W = 89.289\,J\), then the travelled distance of the bullet-block system is:

\(s = \frac{W}{\mu_{k}\cdot (m+M)\cdot g}\)

\(s = \frac{89.289\,J}{0.2\cdot (0.5\,kg + 3\,kg)\cdot \left(9.807\,\frac{m}{s^{2}} \right)}\)

\(s = 13.007\,m\)

The bullet-block system will travel 13.007 meters before stopping.
