a race car around a circular track with a radius of 600 m, experiencing a friction force of 1500 N. If that race car was to drive around another circular track with a radius of 300 m, how much friction would it experience?

The pressure, volume, and temperature of a mole of an ideal gas are related by the equation pv = 8.31t, where p is measured in kilopascals, v in liters, and t in kelvins. use differentials to find the approximate change in the pressure if the volume increases from 14 l to 14.6 l and the temperature decreases from 375 k to 370 k. (round the answer to two decimal places.)

Which type of bond is found between the atoms of a molecule? a. metallic b. delocalized electron c. covalent d. ionic

Could someone me find the answer to this problem.
