First you need to draw the picture of the problem to better understand it. Like the one bellow.
In this task you have 2 sides of triangle and we can calculate angle between them. Angle between them is 120 - 35 = 85 degrees.
Once you have those 3 variables you can calculate third side of triangle using cosine law.
a - second displacement
b - first displacement
c- resultant displacement.
now we just need to calculate this.
a = 196
now, we use cosine law again to find the angle between second and first displacement.
degrees
The angle marked with "?" in the graph is our direction angle. We will call it
Second displacement has magnitude of 196 and a direction of -14.64 with positive x axis
The density will always be the same.
Answer:
There is absolutely No relationship between the weight of an object (which is constant) and the frictional force. If a block is sliding on a surface, that surface will be exerting a force on the block. That force can be resolved into a component parallel to the surface (which we call the frictional component), and a component perpendicular to the surface (called the normal component). For many situations, we find experimentally that the frictional component is approximately proportional to the normal component. The frictional component divided by the normal component is defined to be a quantity called the coefficient of kinetic or sliding friction. The coefficient of kinetic friction obviously depends on the nature of the surfaces involved. The normal component on an object can be decreased if you pull in the direction of the normal component (the weight does not change). However pulling this way on the object not only decreases the normal component, but it also decreases the frictional component since they are proportional. This is why it is easier to slide something if you pull up on it while you push it. If you push down, the normal and frictional components increase so it is harder to slide the object. The weight of an object is the downward force exerted by Earth’s gravity on that object, and it does not change no matter how you push or pull on the object.
I think fluids travel faster near the center of pipes and tubes better than at the edges because they are able to travel much faster, and smoother in the center rather than the edges because the fluids have to turn, which could cause the rest of the incoming fluids to stop, which would make it much slower when traveling through the edges than through the center.
Answer:
Determine the blood glucose level
Explanation:
Determining the blood glucose level of the infant will uncover if the child is affected with hypoglycemia. The increase in the Apgar scores from 7 to 9 in five minutes shows that the newly born child is adapting very well to the outside life.
