у The diagram shows the all of the forces acting on a body of mass 2.76 kg. The three forces have magnitudes F1 = 67 N, F2 = 22.3 N, and F3 = 72.2 N, with directions as indicted in the diagram, where 0 = 40.3 degrees and p = 29.9 degrees. The dashed lines are parallel to the x and y axes. At 1 = 0, the body is moving at a speed of 5.74 m/s in the positive...

4. A chemical engineer is designing a sensor system and needs to know the energy of inter- action of two water molecules. The diagram below shows two water molecules separated by a distance 2d in the x - y plane with x in the horizontal direction. The origin of coordinates is at the water molecule on the left. Large arrows show the directions of the dipole moment vectors of the two water molecules. The magnitude of the intrinsic electric dipole...

1. A mass of 4.00 kg is supported in the X-Y plane by two strings. String 1 pulls up and to the left. String 2 pulls up and to the right. Both strings are attached to the ceiling. String 1 makes an angle of 40.0 degrees with the ceiling. The tension on string 1 is 35.0 N. a) Draw the free body diagram of the mass and two strings. b) What is the magnitude of the X component of the...

Problem 3. (20 points) Consider the following simplified model of a person in static equilibrium in a yoga pose. The diagram below shows the upward normal forces acting on the hands and feet, as well as the downward weight forces on the upper and lower body. There are also horizontal static friction forces on the hands and feet not shown in this diagram. Assume the weight of the lower body has magnitude 250 N and the weight of the upper...

You measure the length of a board with a ruler that is older and has a worn-down end. If you align the end of the board with the end of the ruler, what type of uncertainty does the end of the ruler contribute to the measurement? A) Random B) Systematic The average height of children in kindergarten in Winnipeg is found by measuring the height of one randomly-selected child in every kindergarten class in the city. What type of uncertainty...

4) Read the following and revise your free body diagram as necessary A common confusion when drawing extended free body diagrams is how to draw the force of gravity. For a static equilibrium situation like this, you should draw a single arrow to represent the force of gravity on an extended object. The tail of this vector is placed at the center of mass of the object. It is good practice to pause at this point and think about whether...
