Youjogat9.5km/hfor8.0km, thenyoujumpintoacarand drive an additional 16 km. With what average speed must you drive your car if your average speed for the entire 24 km is to be 22 km/h

Zeros that follow non-zeros numbers and are also to the right of a decimal point are significant

Photoelectrons with a maximum speed of 6.50 x 107 m/s are ejected from a surface in the presence of light with a frequency of 6.75 x 1014hz. if the mass of an electron is 9.10 x 10-31 kg, calculate in joules the maximum kinetic energy of a single electron. 3.84 x 10-15 j 1.92 x 10-15 j 5.92 x 10-23 j 3.07 x 10-16 j
