Explain, using numbered steps, how you could find the volume of a small, irregularly shaped rock.

A person hums into the top of a well (tube open at only one end) and finds that standing waves are established at frequencies of 40.6, 67.7, and 94.7 Hz. The frequency of 40.6 Hz is not necessarily the fundamental frequency.

Listed below are geographic features of the terrestrial worlds. In each case, identify the geological process: impact cratering, volcanism, erosion, or tectonics (where tectonics is any large-scale processes affecting the structure of the planetary

Positive charge Q is placed on a conducting spherical shell with inner radius R1 and outer radius R2. A particle with charge q is placed at the center of the cavity. The net charge on the inner surface of the conducting shell is

1. a. A person weighing 110 pounds has a mass of 50 kg. Using your equation, calculate their weight in newtons.

Consider the moment when the spring is at its maximum compression. At that moment, the kinetic energy, the gravitational potential energy, and the elastic potential energy are, respectively, a - zero, at a maximum, and at a maximum b - at a maximum,

Ari, a young patient who is regularly treated by a psychiatrist, feels compelled to carry out repetitive tasks the same way very frequently. If Ari does not conduct these tasks with extreme precision, he can feel extremely nervous and uncomfortable.

A friend says, "Stars produce energy by a fusion chain reaction of helium into hydrogen." Evaluate the validity of this statement. A) It is an valid statement. Stars produce energy by a fusion chain reaction of hydrogen into helium.

If the mass of a material is 42 grams and the volume of the material is 15 cm^3, what would the density of the material be? answer: Unit:

35. An object of mass m moving at speed v0 strikes an object of mass 2m which had been at rest. The first object bounces backward along its initial path at speed v0.
