Car A and Car B are traveling to the same destination. If Car A is traveling slower than Car B, which statement is true?

Car B will get to the destination sooner or its a one lane road and car A is in front of car B and car B tries to go around and gets in an accident. it's probably the first one :) hope I could help.

the force in each of the chains holding the trapeze bar is D. 330 N

Her weight has to be divided evenly so, divide 660/2= 330 N

State and prove bessel inequality

Statement :- We assume the orthagonal sequence ${{\{\phi\}}_{1}^{\infty}}$ in Hilbert space, now ${\forall \sf \:v\in \mathbb{V}}$ , the Fourier coefficients are given by:

${\quad \qquad \longrightarrow \sf a_{i}=(v,{\phi}_{i})}$

Then Bessel's inequality give us:

${\boxed{\displaystyle \bf \sum_{1}^{\infty}\vert a_{i}\vert^{2}\leqslant \Vert v\Vert^{2}}}$

Proof :- We assume the following equation is true

${\quad \qquad \longrightarrow \displaystyle \sf v_{n}=\sum_{i=1}^{n}a_{i}{\phi}_{i}}$

So that, ${\bf v_n}$ is projection of ${\bf v}$ onto the surface by the first ${\bf n}$ of the ${\bf \phi_{i}}$ . For any event, ${\sf (v-v_{n})\perp v_{n}}$
