Q1. A cart starts from rest at the top of the tilted track. Assume the track is frictionless. The cart passes photo gate A moving at speed 4.19 cm/s, and passes photo gate B moving at speed 6.32 cm/s. The distance between point A and point B is 73 cm.

Q2. Two pipes of equal length are each open at one end. Each has the fundamental frequency of 500 Hz at 325 K. In one pipe the air temperature is increased to 330 K. If the two pipes are sounded together, what beat frequency results?

What is the total charge on the two capacitors : Two ocean liners, each with a mass of 38,000 metric tons, are moving on parallel courses, 92 m apart. What is the magnitude of the acceleration of one of the liners toward the other due to their mutual gravitational attraction? Treat the ships as par.. |

The p-value for the f test for interaction : An experiment was carried out to assess the effects of four tomato varieties and four planting densities on yield. There were 64 plots, and each of the 16 factor combinations was randomly assigned to 4 plots |

What if the ramp was at 45 degrees : A hot wheels track has a spring loaded launcher. A 100g car is pushed into the launcher, which compresses the spring by 2cm. The cars initial velocity after launching is 3m/s. |

Find the magnitude and direction of the electric field : After being accelerated to a speed of 1.7×10 5 m/s, the particle enters a uniform magnetic field of strength 1.00 T and travels in a circle of radius 35.0 cm (determined by observing where it hits the screen as shown in the figure). The results of th.. |

Assume the track is frictionless : Two pipes of equal length are each open at one end. Each has the fundamental frequency of 500 Hz at 325 K. In one pipe the air temperature is increased to 330 K. If the two pipes are sounded together, what beat frequency results. |

What is the minimum force needed : You (height of your eyes above the water, 1.75) are standing 2.00 from the edge of a 2.50--deep swimming pool. You notice that you can barely see your cell phone, that went missing a few minutes before, on the bottom of the pool. |

Find value of the f statistic for testing for interaction : An experiment was carried out to assess the effects of four tomato varieties and four planting densities on yield. There were 64 plots, and each of the 16 factor combinations was randomly assigned to 4 plots. |

Sketch the four possible electric field configurations : An important news announcement is trans- mitted by radio waves to people who are 122 km away, sitting next to their radios, and by sound waves to people sitting across the newsroom, 1.2 m from the newscaster. Take the speed of sound in air to be 345 .. |

What is an average power of its motor during this period : A wheel (radius = 0.20 m) is mounted on a frictionless, horizontal axle. A light rope wrapped around the wheel supports a 0.50-kilogram object, as shown below. When released from rest, the object falls with a downward acceleration of 5.0 m/s2. What i.. |

## Find the magnitude of the resulting magnetic fieldA sphere of radius R is uniformly charged to a total charge of Q. It is made to spin about an axis that passes through its center with an angular speed ω. Find the magnitude of the resulting magnetic field at the center of the sphere. |

## Find the equivalent resistanceA resistor is in the shape of a cube, with each side of resistance R . Find the equivalent resistance between any two of its adjacent corners. |

## What is the electric field at the locationQuestion: Field and force with three charges? What is the electric field at the location of Q1, due to Q 2 ? |
