A sphere of diameter 3.0 cm is mounted into a thin uniform wire of diameter 0.2mm calculate the length of the wire in meters

3600 cm or 36 cm

Explanation:

for sphere,d=6,r=6/2=3cm

for cylindrical wire, d=0.2,r=0.2/2=0.1cm

let the length of wire be x cm

so, according to the question

volume of cylindrical wire = volume of sphere

πr2h =4/3πr3

0.1×0.1×x=4/3×3×3

x=4×3×3×3/0.1×0.1×0.1

x=3600 cm or 36 cm

Hope it's helps

thank you !!

more than, less

less than, more

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
