Physics is one of the fields in science that deals with the physical phenomenon around man, that is matter and its behaviors through space and time. Physics involves the study of several forces such as stress and the deformation it can cause to objects, which can be referred to as strain. The word stress etymologized from the middle English word ‘destresse’, which means ‘distress’. It also derives its meaning from the Latin word ‘strictus’, meaning ‘to draw tight’, and the Old French word ‘estrece’, which means ‘narrowness’ or oppression’.
Stress is the amount of force or tension exerted per area of a particular object. The occurrence of stress can produce strain, that means strain cannot occur without force. Stress has the ability to cause change in a physical body. On the other hand, strain, which is derived from the Latin word ‘stringere’, meaning ‘to tightly bind’, and the old French word ‘estrein’, meaning ‘to press together’ is the alteration in form or shape of an object after the application of stress.
The answer to this is letter B. 4 meters. The reason for this is based on the weights of the people who are using the see-saw. You should remember that the person on one side is 600 N while the person on the other side is 450N.
This means that without knowing where to properly sit, the heavier person will just stay on the ground without any effort. The lighter person should sit 4 meters away from the pivot point so that everything will be balanced. In order to compute, you can use this equation: 600N x 3m = 1800Nm. 1800Nm/450N =4m.
LDR is known as the Light Dependent Resistor. There are two main types of photosensors, and these are known as the LDR or Light Dependent Resistor and the photodiodes. If you were to ask someone who uses photosensors, which one they use, they would tell you that they use the Light Dependent Resistor because those are used more often than the photodiodes. It is used more and it is less expensive.
However, the photodiodes have benefits too over the Light Dependent Resistor. The photodiodes are faster in their response. They are also used in different ways. When using the photodiodes, you must continue to make sure the lighting is good and correct. You don’t need to do that as often with the LDRs.
It should be remembered that while Ohm’s law seems to be very effective, it still has some limitations that should be noted. For example, it will not show details about how semiconductor devices will behave. Another thing is that it cannot be 100% accurate especially when some properties of the item that is being measured changes.
Non-linear elements cannot be measured and used with Ohm’s law too. This is something that you should take note before you decide if this is something that you should use for measuring or not. One example of an item that cannot be measured with Ohm’s law is the filament lamp.
There are two correct answers to this question, which are C. The average position of the robot s weight. and D. The average position of the robot s mass. When an object is at the center of gravity, it is equal on all sides. The center of gravity can vary depending on the object.
Take for example a ball, like a basketball. The center of gravity would be in the middle because the weight is equal on all of the sides of the balls. When it comes to humans, our centry of gravity would be above our ways, because the top half of our bodies outweigh the bottom half.
The example of projectile motion is letter B. This is a type of action that is normally experienced by an object that is being thrown on the surface of the earth. Usually, the movement of the item will be curved as it goes towards a specific direction. Baseball is a prime example of this because when you throw it, it will be affected by gravity. Some items may be thrown but will not immediately hit the ground.
Why is this so? The most common reason is because of the item’s weight. When the item is very light, it will take time before gravity pulls it to the ground. Airflow and strength will also affect how fast or how curved the movement of the ball is going to be.
The correct answer to this question is Albert Einstein. He is a physicist, who coined the term. This is a formula, which correlates energy to mass. When he originally wrote the question, he wrote it as m=L/c2. The L represented Lagrangian, which is a general form of energy.
Each letter in the equation represents something. The E represents energy and it is measured in Joules. This measurement is measured as kg x m2/s2, which stands for kilograms times meters squared per seconds squared. M stands for the mass of an object. Lastly, C is a representation of the speed of light.
A dedicated agent, you might think, is an agent who does a good job because he takes his job seriously, but that’s not the business definition of this term. A dedicated agent is one that is assigned to be very familiar with a certain customer of your company. He knows your company just as your own employees would. He is familiar with your requirements.
Some accounts are so detailed and complex that it proves to be important that just one “dedicated agent” be assigned and follow through with this particular customer. In the case listed, the consultant should recommend to expedite the handling of these cases to enable chatter case feed and add product development team members to the case team.
Coulomb's law can also be referred to as Coulomb's inverse-square law. Physicist Charles-Augustin de Coulomb published the law in 1785. The law was instrumental in developing the theory of electromagnetism. Coulomb's law is experimental. It states that when charges have the same or similar sign, they repel with one another. It also states that when charges have opposite signs, they will attract one another.
This is one of the reasons we have the saying "opposites attract" because different charged signs attract each other. Coulomb's law was very influential in helping scientists bring forth advancements in the electro physics field.
Both specific gravity and density are mostly common in science subjects like physics and even chemistry. Specific gravity and density are not the same when you consider their meanings and how they are calculated. Specific gravity can be defined as the ratio of the weight of a substance with the weight of an equal volume of water, while density can be defined as the ratio of the mass of an object to the volume.
Specific gravity does not have any unit because it is talking about the ratio of two weights, which means the unit of each ratio would have canceled each other. Density on the other hand has a unit and it is kilogram per cubic meter. When calculating the density an object, the mass and the volume of the object must be known. Specific gravity sometimes can be used to determine the concentration of a given solution that is in large quantity.
