The two pulses will have Constructive interference. Constructive interference occurs when the maxima of two waves add together (the two waves are in phase), so that the amplitude of the resulting wave is equal to the sum of the individual amplitudes.
What is constructive interference?
Constructive interference occurs when the maxima of two waves add together (the two waves are in phase), so that the amplitude of the resulting wave is equal to the sum of the individual amplitudes. Equivalently, the minima of the waves would be aligned
This is an example of a standing wave produced when two ends of a string are oscillated in the same plane. The displacement of of point on two ends oscillates vertically.
We are given that two pulses move along the string each coming towards each other and meet at a common point ( P ).
Each pulse have their own magnitude or displacement in the vertical plane. If the pulses are to meet at a common point at the same instant, then they interfere with each other constructively.
Where constructive interference of two pulses is the addition of magnitudes of induvidual pulses and form a single puls of the constructed magnitude.
magnitude ( New pulse ) = magnitude (Pulse 1) + magnitude (Pulse 2)
Hence the two pulses will have Constructive interference

In science, a new hypothesis must be (mark all correct answers):
1. falsifiable by experimental testing or observations.
2. completely consistent with all previous laws and theories of science.
3. possible to prove correct.
4. based solely on physical causes.
Answer:
1, 2, and 3.
Explanation:
Hypotheses must be able to be proven false, otherwise it’s a law. It must be consistent with other theories otherwise it’s not true, and it has to be possible to prove correct, otherwise it’s a theory.
The true statement is "Falsifiable by experimental testing or observations." The correct option is 1.
In science, a hypothesis is a proposed explanation or prediction for a phenomenon or set of observations.
A new hypothesis is a fresh idea put forth by a scientist to explain a phenomenon or observation that has not been explained or understood fully by existing scientific theories or hypotheses.
The new hypothesis should be based on previous knowledge and observations, and it should be testable and falsifiable through experiments or observations. Scientists use hypotheses to guide their research and develop theories, which are more comprehensive explanations backed up by multiple lines of evidence.
Therefore, only Option (1) is the correct answer.

A truck covers a distance of 360 km in 5 hrs. Find its speed
Answer:
72 km / hour
Explanation:
Speed equals to distance over time. We are given distance equal 360 km and time in 5 hours.
Hence:
[tex]\displaystyle \large{s=\frac{360}{5}}\\\displaystyle \large{s=72}[/tex]
Therefore, the speed is 72 km / hour.
Notes
Sometimes, speed is defined as ‘v’ while velocity is defined as ‘v vector’ indicating that velocity is speed with direction and speed is just velocity with only magnitude.

Which changes in an electric motor will make the motor stronger? select 3 options. using a stronger permanent magnet using a weaker permanent magnet increasing current in the electromagnet decreasing current in the electromagnet increasing the distance between the magnets decreasing the distance between the magnets
1. Using Strong Permanent. 2. increasing the current. 3. Decreasing the space between Magnets
Explanation:
Brainiest
The changes that make the motor stronger will be using strong permanent magnets, increasing the current, and decreasing the space between magnets.
What is an electric motor?An electric motor is a mechanism that turns electricity into mechanical energy.
The interaction between the motor's magnetic field and electric current in a wire winding generates force in the form of torque imparted to the motor's shaft in most electric motors.
An electric generator is physically equivalent to an electric motor, but it converts mechanical energy into electrical energy using a reversed flow of power.
When string magnets are used, a strong flux is produced, and the motor becomes more powerful. Internal flux has a significant impact on coil strength.
Increasing current results in greater power. In the same way, shortening the distance between magnets makes the motor stronger by increasing flux and torque.]
Hence the changes that make the motor stronger will be using strong permanent magnets, increasing the current, and decreasing the space between magnets.

We call this interaction the principle of superposition.
The resultant wave of the different wave functions is = y1 + y2
Calculation of the resultant wave functionsThe principle of superposition states that two waves moving through the same medium, the resultant value of the wave function is the sum of the different wave functions.
Waves superimpose by adding their disturbances,each disturbance corresponds to a force, and all the forces add.
Therefore, the resultant wave of the different wave functions is the addition of both wave functions which is = y1 + y2.
