Q. The head of a rattlesnake can accelerate at 50.0 m/s^2 in striking a victim. If a car could have the same acceleration, how long would it take for it to reach a speed of 100.0 km/h from rest?

Q. A charge of -4.00 nC and a charge of -5.40 nC are separated by a distance of 70.0 cm. Find the position at which a third charge of +7.60 nC can be placed so that the net electrostatic force on it is zero.

## What is the sign of the charge on the wireHow many 95W light bulbs can you use in a 120V circuit without tripping a 17A circuit breaker? (The bulbs are connected in parallel, which means that the potential difference across each light bulb is V.) |

## After a short time, what is the temperature of the water110 grams of boiling water (temperature 100° C, heat capacity 4.20 J/gram/K) are poured into an aluminum pan whose mass is 1000 grams and initial temperature 24° C (the heat capacity of aluminum is 0.9 J/gram/K). |

## Average power spent in turning a crank handleA person is making homemade ice cream. She exerts a force of magnitude 22 N on the free end of the crank handle, and this end moves in a circular path of radius 0.28 m. The force is always applied parallel to the motion of the handle. If the handl.. |

## Calculate the force that can be resisted by a pistonIf a 200 N force F1 is applied to the piston with the 4 cm diameter, Calculate the magnitude of the force F2 that can be resisted by the piston with the 10 cm diameter? Ignore the weights of the pistons. |

## What is the gravitational force on satelliteTake the gravitational constant to be = 6.67×10^-11 Nm^2/kg, the mass of the earth to be = 5.97×10^24 kg, and the radius of the Earth to be = 6.38×10^6 m. |

## What is the magnitude of the forceWhat is the magnitude of the force that maintains circular motion acting on puck. |

## Determine the value of igdetermine the value of IG. The support at B does not move while the measurement is taken. For the calculation, the horizontal location of G should be determined. |

## Compute the inner hollow volume of the ballRicardo and Jane are standing under a tree in the middle of a pasture. An argument ensues, and they walk away in different directions. Ricardo walks 24.0 in a direction 60.0 west of north. Jane walks 12.0 in a direction 20.0 south of west. They then .. |

## Maximum height reached by the diverFind maximum height reached by the diver using the equation of motion. |

## What is the high temperature t1At one instant a bicyclist is 35.0m due east of a park's flagpole, going due south with a speed of 20 m/s. Then, 19 s later, the cyclist is 60.0 m due north of the flagpole, going due east with the speed of 11 m/s. For the cyclist in this 19s inte.. |

## What about the electric potential energyA 2.16 kg block on a horizontal floor is attached to a horizontal spring that is initially compressed 0.0320 m. The spring has force constant 840 N/m. |
