Answer» ANSWER: 12000 Pascals Explanation: AREA = 20 $cm^{2}$ = $\frac{20}{10000} m^{2}$ = $\frac{1}{500} m^{2}$ $Pressure =\frac{Force}{Area}$ $= \frac{2400}{\frac{1}{500} }$ $= \frac{24 * 500}{1}$ $Pressure = 12000 \ N/m^{2}$ $= 12000 \ Pascals$

11.

A force of 2400 N acts on the surface of area 20 cm normally. What would be thepressure on the surface?

Answer»

ANSWER:

12000 Pascals

Explanation:

AREA = 20 $cm^{2}$ = $\frac{20}{10000} m^{2}$ = $\frac{1}{500} m^{2}$

$Pressure =\frac{Force}{Area}$

$= \frac{2400}{\frac{1}{500} }$ $= \frac{24 * 500}{1}$

$Pressure = 12000 \ N/m^{2}$

$= 12000 \ Pascals$

17.	Which of the following is not an example of cerebral reflex?a) Salvation at the sight of foodb) Peristalsisc) Blinking of eye when bright light is focussed on themd) Withdrawal of hand after coming in contact with hot water
Answer» Answer: Hello my friend Explanation: Reflex action is induced by the motor nerves. It is an involuntary and INSTANT movement in response to a stimulus. A reflex action is done by neural pathway of reflex arc. In this, the action is done before the impulse reaches the brain. Out of the given options, sweating is not a reflex action. Salivation is a reflex action in which smell of food activate neural pathway and activates muscles and glands. This releases salivary juices. When someone is pinched by a needle, it activates neural pathway to EVOKE a response. The skin receptors quickly send NERVE impulses to the spinal CORD and response is relayed back. Apart from these, COUGHING, sneezing and blinking of eyes are also reflex actions. Thus, the correct answer is 'Sweating.'

Answer»

just SIMPLY APPLY KVL on the circuit

Explanation:

12v=I(R1+R2+R3+R4)

12V=I(4+3+5+12)

12V=I(24)

I=0.5
