Answer:

Option A

The four major tasks of the digestive system are - Ingestion, Digestion, Absorption, Elimination

Explanation:

A digestive system has primarily four main functions

a) Motility - In this the food is ingested through opening in the form of mouth and then it starts moving from the mouth via esophagus to the stomach

b) Digestion - In the stomach, the food gets digestion and then it is passed on to the intestine

c) Absorption - In the small intestine essential nutrients and water is absorbed

b) Secretion - The waste remaining after intestine digestion is passed on to the rectum for secretion

Hence, option A is correct

You and a friend both leave the same restaurant to drive home. You are heading directly west at 30 miles per hour and he or she

steposvetlana [31]

Answer:

$\frac{dAB}{dt} = = 50 miles/ hour$

Explanation:

let A represent me and B represent my friend

A speed $\frac{dOA}{dt}$ =30 m/hr toward west

B speed $\frac{dOB}{dt}$ =40 m/hr toward south

after 1/2 hr

total distance cover by A =1/2 * 30 miles = 15 miles

total distance by B = 1/2*40 miles = 20 miles

now from figure

$AB = \sqrt{(15^2+20^2)} = 25 miles$

$AB^2 =OA^2+ OB^2$

Differentiate above equation

$2AB\frac{dAB}{dt} = 2OA\frac{dOA}{dt} +2OB\frac{dOB}{dt}$

$25*\frac{dAB}{dt} = 15*30 +20*40$

$\frac{dAB}{dt} = \frac{1250}{25}$

$\frac{dAB}{dt} = = 50 miles/ hour$

A long straight wire carries a 40.0 A current in the +x direction. At a particular instant, an electron moving at 1.0  107 m/s

ser-zykov [4K]

Answer:

$F=-1.28\times 10^{-16}\ N$

Explanation:

Given that,

Current flowing in the wire, I = 40 A (+x direction)

Speed of the electron, $v=10^7\ m/s$ (+y direction)

Distance from the wire, r = 0.1 m

Let F is the electric force on the electron. It is given by :

$F=qvB\ sin\theta$

Here, $\theta=90$

$F=qvB$

Here, $B=\dfrac{\mu_oI}{2\pi r}$

$F=qv\dfrac{\mu_oI}{2\pi r}$

$F=-1.6\times 10^{-19}\times 10^7\times \dfrac{4\pi\times 10^{-7}\times 40}{2\pi \times 0.1}$

$F=-1.28\times 10^{-16}\ N$

So, the force on the electron at this instant is $-1.28\times 10^{-16}\ N$ . Hence, this is the required solution.
