What is the difference between sensation and perception?

2 answers:

5 0

The difference between sensation and perception is that the two are completely different elements in terms of how they receive and acknowledge information. Sensation is the physical stimulus, together with its physical properties, it goes by sensory organs. By then, the organs start to decode all the information that they just got and transform them into neural impulses or signals.

At critical temperature, the resistivity of the superconductor

B. It suddenly drops to zero

Explanation:

Materials can be classified into three different types depending on their resistance:

Conductors: these materials have generally low resistance and allow electricity to pass through easily. The resistance of a conductor increases linearly with the temperature
Insulators: these materials do not allow electricity to pass through - so they have very high resistance
Semi-conductors: these are materials that are insulators are room temperature, however they becomes conductors when heated. Therefore, the resistance of a semiconductor decreases when the temperature increases
Superconductors: these are special materials that are normally conductors; however, at very low temperatures (we are talking about temperature very near to 0 K), their resistance becomes suddenly zero.

Therefore, the correct answer is:

B. It suddenly drops to zero

Martije has made a slight error in naming a compound monocarbon tetrabromide. What compound is she most likely naming, and what

Alik [6]

Answer: $CBr_4$ : carbon tetrabromide

Explanation:

$CBr_4$ is a covalent compound because in this compound the sharing of electrons takes place between carbon and bromine. Both the elements are non-metals. Hence, it will form covalent bond.

The naming of covalent compound is given by:

1. The less electronegative element is written first.

2. The more electronegative element is written second. Then a suffix is added with it. The suffix added is '-ide'.

3. If atoms of an element is greater than 1, then prefixes are added which are 'mono' for 1 atom, 'di' for 2 atoms, 'tri' for 3 atoms and so on.

Hence, the correct name for $CBr_4$ is carbon tetrabromide.

Neutron stars are extremely dense objects formed from the remnants of supernova explosions. Many rotate very rapidly. Suppose th

mihalych1998 [28]

Answer:

10989.55932 rad/s

Explanation:

m = Mass of object

M = Mass of neutron star = $2\times 1.989\times 10^{30}\ kg$

R = Radius of neutron star = 13000 m

G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²

$\omega$ = Angular speed

Here, the gravitational force will balance the centripetal force

$\dfrac{GmM}{R^2}=mR\omega^2\\\Rightarrow \omega=\sqrt{\dfrac{GM}{R^3}}\\\Rightarrow \omega=\sqrt{\dfrac{6.67\times 10^{-11}\times 2\times 1.989\times 10^{30}}{13000^3}}\\\Rightarrow \omega=10989.55932\ rad/s$

The greatest possible angular speed an object can have is 10989.55932 rad/s
