Question

What volume of o2 at stp is required for complete combustion of 200 c3 of c2h2 and what would be the volime of co2 produced at stp?

Answer 1

The uncertainity of a moving bullet of mass 10g is 10^-5 m. Calculate the uncertainity in its velocity?

According to uncertainty principle

Δx.Δmv = ℎ / 4π

Δv = ℎ 4πmΔ

x=6.626 × 10−34 / 4×3

=> ×14×10−2×10−5

=> 5.27×10−28 m/s ...
