The diagram represents a pan balance each of the blocks marked x has the same value. 17. An object placed on an equal-arm balance requires 12 kg to balance it. When placed on a spring scale, the scale reads 12 kg. Everything (balance, scale, set of weights and object) is now transported to the Moon where the free-fall acceleration is one-sixth that on Earth. The new readings of the balance and spring scale (respectively) are: When the object is at x = A/2, U = ½ k(A/2) 2 = E. tot /4. Since the mechanical energy is conserved, the kinetic energy at x = A/2 is given by, K = E. tot -U = 3E. tot /4. Motion Graphs. If we graph position, velocity, and acceleration of the object on the spring, as a function of time, we get the plots shown at right. The example used here ...

The sensor, controller and actuator in this example are our eyes, our brain, and our hand, respectively. This is an example of a feedback control system. each object, and particles with a larger size have a larger mass.] Explain your reasoning. 40 4. In Figure 4 below, a graph shows the relationship between mass and volume for two substances, A and B. Use the graph to answer questions about these two substances. Two Pan Balance a) You have built a simple two-pan balance shown above to compare the The Peak value represents the distance to the top of the waveform measured from a zero reference. For discussion purposes we'll assign a Peak value of 1.0. The Peak-to-Peakvalue is the amplitude measured from the top most part of the waveform to the bottom most part of the waveform. The Average value is the average amplitude value for the ... Finally, sketch a line through the points and label it “Demand for X.” (Assume that the demand curve for X is a straight line.) d) For extra practice, try assuming that the price of Y changes instead of the price of X. Suppose the new situation has price levels Px = $5 and Py = $5 (this is our “situation 3”).

Measuring Mass with a Triple-Beam Balance A triple-beam balance has a pan and three beams with sliding masses called riders. At one end of the beams is a pointer that indicates whether the mass on the pan is equal to the masses shown on the beam. To use: 1. Make sure the balance is zeroed before measuring the mass of an object.

Block 1 and block 2 have the same mass, m, and are released from the top of two inclined planes of the same height making 30° and 60° angles with the horizontal direction, respectively. If the coefficient of friction is the same in both cases, which of the blocks is going faster when it reaches the bottom of its respective incline?

Name and label each contact force acting on the object. There is at least one force at each point of contact; there may be more than one. When necessary, use subscripts to distinguish forces of the same type. Name and label each long-range force acting on the object. For now, the only long-range force is weight.

1. Every body continues in its state of rest, or of uniform motion in a right line, unless it is compelled to change that state by forces impressed on it. 2. The (rate of) change of motion is proportional to the motive force impressed: and is made in the direction of the right line in which that force is impressed.
