The factors influencing the rate of chemical reaction are concentration of the reactant,Surface area and physical condition of the reactants, Temperature, and catalyst.

One or more compounds, known as reactants, are transformed into one or more distinct substances, known as products. Such a process is known as a chemical reaction.

Following are the factors Influencing the rate of chemical reaction;

1. Concentration of the reactant.

The reaction is usually accelerated by increasing the concentration of one or more reactants. This occurs because a higher concentration of a reactant results in more collisions with that reactant in the same amount of time.

2. Surface area and physical condition of the reactants.

The pace of reaction is limited by the surface area of the in contact phases if reactant molecules reside in different phases, as in a heterogeneous mixture.

3. Temperature.

The rate of reaction is typically accelerated as the temperature rises. As the temperature rises, the average kinetic energy of the reactant molecules increases.

4. Catalyst

A catalyst is a substance that aids in the process without being ingested.

Catalysts provide a second reaction pathway for the production of goods. They play a crucial function in a variety of biological processes.

Answer:

A scalar quantity is a quantity that has magnitude but does NOT have direction. An example is speed.

While a vector quantity is a quantity that has BOTH magnitude and direction. For example, force.

Owing to the fact that the speed of the cars  did not change, the momentum of the objects will not change.

Momentum refers to the product of mass and velocity. According to the laws of conservation of linear momentum, momentum is conserved before and after collsion.

Resistance in the wire increases when the temperature of the wire is increases.

Heating the metal conductor causes atoms to vibrate more that makes more difficult for the electrons to flow through the conductor and thus increasing resistance.

Answer:

so therefore, the comb gains electron and the hair losses electrons

Explanation:

It is known that electron contain a negative charge.

So, when an atom gain electrons then number of electrons within the atom increases. As a result, the atom acquires a negative charge.

But when an atom loses electrons, there will be deficiency of electrons within the atom. As a result, the atom becomes positively charged.

Hence,, when people use plastic combs on their hair, the combs become negatively charged. The situation which is true about this is the comb gains electrons and the hair loses electrons.

Calculate the area under the line (integrate)

Quite easily you would know that Work done is force times displacement. So by finding the area under the line he could easily tell the work done

Jordan is using a graph to solve this problem, and the last step in the process would be to calculate the area under the line.  The answer is option D.

In the context of graphs, the area under the line refers to the area enclosed between a line on a graph and one of the axes. The area can be calculated by finding the product of the base of the shape formed by the line and the axis, and the height of the shape, which is the vertical distance between the line and the axis.

For example, in a force-displacement graph, the area under the line represents the work done by the force on an object as it is displaced. By finding the area under the line on this graph, you can calculate the amount of work done on the object by the force.

Here's a brief explanation of the steps involved in solving this problem using a graph:

Step 1: Draw the axes for a force vs. displacement graph.

The x-axis represents displacement and the y-axis represents force. Mark the point where the weight is released (displacement = 0, force = 0) and the point where it falls 45 meters (displacement = 45, force = 1,200 * g, where g is the acceleration due to gravity).

Step 2: Draw the line on the graph.

Draw a straight line connecting the two points on the graph.

Step 3: Calculate the gravitational force.

Calculate the force due to gravity acting on the weight by multiplying its mass (1,200 kg) by the acceleration due to gravity (9.81 m/s^2):

F = m * g

F = 1,200 kg * 9.81 m/s^2

F = 11,772 N

Step 4: Calculate the area under the line.

The area under the line represents the work done on the weight by gravity. To calculate this area, we need to find the area of the triangle formed by the line and the x-axis:

Area = (base * height) / 2

Area = (45 m * (1,200 * g) N) / 2

Area = 26,460 J

Therefore, the work done on the weight by gravity when it falls 45 meters is 26,460 J. The correct option is D i.e Calculate the area under the line.

Answer:

equal

Explanation:

If all three corresponding sides are equal and all three corresponding angles are identical in measure, two triangles are said to be congruent. These triangles can be slides, rotated, flipped and turned to be looked identical. If repositioned, they coincide with each other. The symbol of congruence is' ≅'.

Congruent means equal, as it is a term used to describe two or more objects or figures that have the same shape and size.

When two or more figures or things have the same size and shape, they are said to be congruent.

When we state that two things or figures are congruent, we mean that their lengths, angles, and proportions are all the same.

The idea of congruence is that there should be no distinction or contrast between the things being compared. It denotes complete equality and a perfect match.

Congruence informs us that all geometric shapes, including line segments, angles, triangles, and others, are the same and can be placed on one another without overlap or gaps.

Thus, a fundamental idea in geometry called congruence enables us to evaluate and contrast geometric forms and their characteristics.
