Thepotemich [5.8K]

Answer:

Nervous; nervous.

Explanation:

A sensory system can be defined as components of the central nervous system (CNS) which comprises of the brain, neural tissues or pathways and sensory neurons responsible for sensory functions, perception and processing sensory informations such as sound, light, heat, etc.

Basically, the central nervous system (CNS) interprete the neural signals that are generated from stimuli that are detected by the sensory system. The five (5) main sense organs in the sensory system are: skin, tongue, ears, nose and the eyes.

Generally, the nervous system found in living organisms such as humans, comprises of two (2) major components or systems; a central nervous system (CNS) and a peripheral nervous system (PNS).

Consider the formation of nitryl fluoride: 2NO2(g)+F2(g)⇌2NO2F(g) The reaction is first order in F2 and second order overall. Wh
Dahasolnce [82]

Answer:

Rate = k[NO_{2}][F_{2}]

Explanation:

  • Two reactants are present in this reaction which are NO_{2}and F_{2}
  • We know overall order of a reaction is summation of individual order with respect to reactants present in rate law equation.
  • Here, overall order of reaction is 2 including first order with respect to F_{2}
  • So, rate of reaction should also be first order with respect to another reactant i.e. first order with respect to NO_{2}
  • So, rate law: rate = k[NO_{2}][F_{2}]

What volume of a 2.00 m kcl solution is required to prepare 500. ml of a 0.100 m kcl solution?
den301095 [7]

To solve this we use the equation, 

M1V1 = M2V2

where M1 is the concentration of the stock solution, V1 is the volume of the stock solution, M2 is the concentration of the new solution and V2 is its volume.

2 M x V1 = 0.1 M x .5 L

<span>V1 = 0.025 L or 25 mL of the 2 M KCl solution is needed</span>

A Pitot-static probe is used to measure the speed of an aircraft flying at 3000 m. If the differential pressure reading is 3100
inessss [21]

Answer:

82.59 m/s or 297.324 km/h

Explanation:

From the question,

Applying

V = √[2(P'/ρ)].................. Equation 1 ( From

Where V = Speed of the aircraft, Differential Pressure of the air craft, ρ = Density of air at an altitude of 3000 m.

Given: P' = 3100 N/m², ρ = 0.909 kg/m³

Substitute into equation 1

V = √[2(3100/0.909)]

V = √(2×3410.34)

V = √(6820.68)

V = 82.59 m/s

V = 297.324 km/h

Hence the speed of the aircraft is  82.59 m/s or 297.324 km/h
