What is the net force on a ball that falls downward?

Which definition is correct and uses only quantities rather than units? A. Density is mass per unit volume B. potential difference is energy per unit current C. Pressure is force per unit area D. speed is distance travelled per second

Technician A says a special puller and installer tool is required to remove and install the vibration damper. Technician B says if the inertia ring on the vibration damper is loose, the damper must be replaced. Who is right?

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.
