Question

when an air particle speeds up, it actually pushes . Complete the sentence

• A. Less
• B. More
• C. Inside
• D. Outside

Answer 1

The correct option is A Less

According to Bernoulli's theorem $P+\rho gh+\frac{1}{2}\rho v^2=constant$

$⟹$ When $v$ is more, then pressure $\left(P\right)$ is less.

Thus when an air particle speeds up, it actually pushes less.
