A bowler lifts her bowling ball a distance of 0.5 meters using 35 joules of energy. What is the mass of her bowling ball?

What should the power status of a circuit be when measuring resistance with an ohmmeter?

The energy released by a chemical reaction can be measured using a calorimeter. when barium hydroxide octahydrate crystals are reacted with dry ammonium chloride inside of a coffee cup calorimeter, the temperature of the 18.00 g of water in the calorimeter decreases from 30.0°c to 8.0°c. the equation for calculating energy absorbed or released by a reaction is: where q is the energy released or absorbed, m is the mass of water in the calorimeter, cp is the specific heat of water, and δt is the observed temperature change. if the specific heat of liquid water is 4.19 j/g·°c, how much energy was absorbed by the reaction?

If an athlete runs once around a track, back to the starting line, her average velocity is zero. true or false?
