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.

The equation E=mc2 was formulated by the great physicist Albert Einstein. Matter contains energy. To quantify this relationship, equation E=mc2 had been formulated. It states the correlation of energy and mass (the sum total of matter that forms a body or an object).Energy is denoted by E and its unit of measurement is Joule. Mass is denoted by m and its unit of measurement is kilograms or grams. c is the speed of light.When mass of an object is multiplied by the square of speed of light, then we get the energy contained within to object.

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.

It would make sense that it would increase because there would be more crests or troughs per second, meaning the frequancy is increased. One might be inclined to say that it would double, however, we do not know the exact amount of increase.

6 mDistance of image to the object is (d + d) new d = 5-2 = 3 m d= d = 3m therefore d+d = 3+3 = 6m

Could someone please explain the working out for this question?Thank you

When two objects collide like cars, it is important to determine the magnitude of the crash based on the velocity and speed of the two items. To do that, you need to divide the mass or weight of the objects by the speed. In this case, the mass of one skater is 65 kilograms and the other mass of the other skater is 45 kilograms. Then you have to find out how fast each skater is moving. In this case, one skater is moving at 13 meters per second and she has a velocity of magnitude of eight meters per second. Therefore, you can calculate through the formula the magnitude of Daniel’s velocity after the collision which is five meters per second.

None of these answers can be properly concluded. At every point along the rope, action = reaction. In a tug-of-war, at every point in the rope the forces pulling to the left are essentially equal to the forces pulling to the right. Usually the acceleration is low and the mass of the rope is low. The tension in every point along the rope is the same and the acceleration is negligible, meaning the forces applied by both teams are almost identical. If the rope is going to break, it will break at its weakest point, as a result of the combined force of both teams.

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 middle of the robot.. The average position of the robot s height.

Yes I got D - but sound waves can travel through gases- they are just a transfer of energy and everyday we hear each other by the wave of energy travelling thorugh gasso there should be another option of - 1 & 5

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.
