Using Heisenberg's Principle, calculate for the following positions.

a) a 1.54-mg mosquito moving at a speed of 1.82 m/s if the speed is known to within ± 0.01 m/s

b) a proton moving at a speed of (4.67 ± 0.02) 104 m/s

When I solved (a) I got 1.88e-30 and (b) I got 3.41e-5 but the computer says neither are right. I missed this day so I don't know what I'm doing wrong can anyone help?
