In physics, the wavelength is the spatial duration of a periodic wave—the distance over which the wave's shape repeats. it is the gap between consecutive corresponding points of the same section on the wave, including two adjoining crests, troughs, or 0 crossings, and is a feature of each traveling wave and standing wave, as well as other spatial wave patterns. The inverse of the wavelength is known as the spatial frequency. Wavelength is normally exact by means of the Greek letter lambda (λ). The time period wavelength is also now and again implemented to modulated waves, and to the sinusoidal envelopes of modulated waves or waves fashioned with the aid of interference of several sinusoids.
Assuming a sinusoidal wave shifting at a set wave speed, the wavelength is inversely proportional to the frequency of the wave: waves with better frequencies have shorter wavelengths, and decreased frequencies have longer wavelengths.

Example: A ball rolls off a table 1.5 m high and lands 0.80 m away from the table.
(a) How long will the ball be in the air?
(b) What is the ball's initial horizontal velocity?
(c) What will be the ball's horizontal and vertical velocities when it hits the ground?
Answer:
Below
Explanation:
To fall 1.8 m the time will be found with :
d = 1/2 a t^2
1.5 = 1/2 ( 9.81) t^2 shows t = .55 s
in this .55 s it travels .8 m horizontally
Horizontal velocity = .8 m / .55 s = 1.45 m/s
When it hits the ground , horizontal velocity will still be 1.45 m/s
vertical velocity will be v = at = 9.81 m/s^2 * .55 = 5.42 m/s

What is the formula of 3 law of motion?
The three laws of motion, as described by Sir Isaac Newton, are as follows:
Every object in a state of uniform motion will remain in that state of motion unless an external force acts on it. This is known as the law of inertia.
The force acting on an object is equal to the mass of that object multiplied by its acceleration. This is known as Newton's second law of motion, and is often represented by the equation F = ma.
For every action, there is an equal and opposite reaction. This is known as Newton's third law of motion.
Newton's laws of motion are fundamental principles that describe the physical behavior of objects in motion. The first law, the law of inertia, states that an object at rest will remain at rest, and an object in motion will continue in motion with a constant velocity, unless acted upon by a net external force. The second law of motion, states that the acceleration of an object is directly proportional to the net force acting on the object, and inversely proportional to its mass. The third law states that for every action there is an equal and opposite reaction.

Load distance = 5 m
In mechanics, force is any action that tends to maintain or alter the motion of a body or distort it. The concept of force is commonly explained in terms of Isaac Newton's three laws of motion, as stated in his Principia Mathematica (1687). Newton's first principle states that a body at rest or moving at a uniform rate in a straight line will remain in that state until some force is applied to it. The second law states that when an external force acts on a body, it causes an acceleration (change in velocity) of the body in the direction of the force.

Due to the surface makeup and the product that spilled, what is the direction most hazardous materials will spread based on their viscosity
Due to the surface makeup and the product that spilled, Downhill/Downwind is the direction most hazardous materials will spread based on their viscosity.
The viscosity of a fluid (liquid or gas) is its resistance to a change in form or movement of neighbouring sections relative to one another. Viscosity signifies resistance to flow. The SI unit is poiseiulle (PI).
It relates to the colloquial sense of "thickness" in liquids: syrup, for example, has a higher viscosity than water. The strength of the compensatory force is related to the viscosity of the fluid in a tube with a constant rate of flow.
In general, viscosity is affected by the condition of a fluid, such as temperature, pressure, and rate of deformation. However, in certain circumstances, the reliance on some of these features is minor. The viscosity of a Newtonian fluid, for example, does not vary appreciably with the rate of deformation. Only at very low temperatures is zero viscosity (no resistance to shear stress) observed in superfluids; otherwise, the second law of thermodynamics requires all fluids to have positive viscosity.

Mechanics sometimes use a piece of pipe to lengthen the handle of a wrench when trying to remove a very tight bolt. How does this make it easier for the mechanic to remove the bolt
Answer:
increase the length of the handle from the bolt, the torque will increase even if you have the same force
Explanation:
It allows them to apply more torque to the bolt. Torque is the turning or twisting force that causes rotation, in this case, it's applied to the bolt in an effort to loosen it. By lengthening the handle of the wrench, the mechanic is able to leverage more of their body weight and strength behind the wrench, increasing the torque they are able to apply to the bolt.
When a bolt is very tight, it can be difficult to turn it with a standard wrench. The increased torque provided by the longer handle allows the mechanic to apply more force to the bolt, which can help to loosen it. This can be particularly useful in situations where the bolt is corroded, rusted, or otherwise stuck due to a buildup of debris or other factors.

I am writing to you from the future to tell you that your theory of continental drift has been proven to be true. However, I understand that during your lifetime, you were not able to convince the scientific community of the validity of your ideas. I want to share with you some of the evidence that was discovered after your time that helped to solidify the theory of plate tectonics.
Firstly, the discovery of the mid-Atlantic Ridge in the 1920s provided evidence for the existence of a divergent boundary. This underwater mountain range, which runs down the center of the Atlantic Ocean, is evidence of the separation of the North American and Eurasian plates. Another key piece of evidence is the matching of rock formations and fossil records on opposite sides of the ocean.
Furthermore, the study of earthquakes and volcanoes also helped to support the theory of plate tectonics. The locations of earthquakes and volcanoes corresponded with plate boundaries, and the movement of these plates could explain their occurrence.

In the particles of a substance when heat is released and the temperature becomes lower are the particles will move more slowly.
A particle can vibrate due to heating so that the particle can be said to have kinetic energy. Kinetic energy itself is affected by the mass and speed of objects. The smaller the mass of an object, the greater its kinetic energy. The faster the particles vibrate, the greater their kinetic energy.
When a particle is heated, its temperature will rise and the particle will move fast because it gains kinetic energy. Meanwhile, when a particle loses heat, the temperature of the particle will decrease, this causes a decrease in the kinetic energy of the particle due to heat loss so that the particle moves slower.

Is there ever a case where one of the two charges in Coulomb's Law experiences a different force magnitude than the other charge? Why or why not?
Answer:
Yes, there is a case where one of the two charges in Coulomb's Law experiences a different force magnitude than the other charge. Coulomb's Law states that the electric force between two charged particles is directly proportional to the product of the magnitudes of the charges and inversely proportional to the square of the distance between them. If the magnitudes of the charges or the distance between them changes, the force experienced by one of the charges will also change. For example, if one of the charges is doubled in magnitude while the other charge and the distance between them remain the same, the force experienced by the charge with the increased magnitude will also double.
