Ten identical lengths of wire are laid closely
side-by-side. their combined width is measured
and found to be 14.2 mm. calculate:
a the radius of a single wire
b the volume in mm of a single wire if its
length is 10.0 cm (volume of a cylinder =
tr’h, where r=radius and h= height).

can you find b

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

The force needed to overcome static friction is usually less than that needed to overcome kinetic friction.true or false?
