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

explanation:

f=ma newton

f=100x2.5=250n

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
