Explain transparency

Answer»

We know that light TRAVELS in a straight line. Also, some objects allow light to pass through them while others do not. Today, we will LEARN about these types of objects in details.

There are three types of objects according to the amount of light that can pass through them. These are:
⏩Transparent Objects
⏩Translucent Objects
⏩Opaque Objects

\textbf  {TRANSPARENT OBJECTS}

When you can see through any OBJECT very clearly, then the object can be called a Transparent Object. In other words, when light can pass through any objection WITHOUT any deflection, then the object is transparent.

For example - Water, Glass, etc.

\textbf{TRANSLUCENT OBJECTS}

Translucent Objects are the ones through which light can pass but with a few deflections / deviations. In other words, you can partially see through these objects.

For example - COLOURED Glass, Oil, Butter Paper, etc.

\textbf {OPAQUE OBJECTS}

The objects which don't allow any light to pass through them are termed as Opaque Objects. In other words, you can't see through these objects at all.

For example - Wood, Metals, Thick Papers, etc.

Regulations of cardiac activities.

Answer»

Hi.


here is your answer. .


NORMAL activities of the heart are regulated by intrinsically, i.e auto regulated by specialised MUSCLE hence the heart is called myogenic.


A special neural centre in the medulla oblengata can modrater the cardiac functions through AUTONOMIC nervous system.



Neural SIGNAL through the symphatic nerves part of ANS can increase the rate of heart beat the strength of VENTRICULAR contraction and thereby the cardiac output.



Another component of ANS decrease the rate of heart beat speed of conduction of action potential and thereby cardiac output.

What are two conditions which promotes corrosion ?What are two conditions which promotes corrosion ?What are two conditions which promotes corrosion ?What are two conditions which promotes corrosion ?What are two conditions which promotes corrosion ?What are two conditions which promotes corrosion ?​What are two conditions which promotes corrosion ?

Answer»

the two condition

Presence of an ELECTROLYTE. The first is the presence of a substance that will CONDUCT electricity and therefore allow the movement of electrons, resulting in the oxidisation of a metal, eg, rust. Commonly, water is associated with CORROSION for when it holds impurities, it will readily conduct electrons. Such impurities are ionic salts such as SODIUM CHLORIDE, acids (commonly those associated with rotting vegetable matter) or alkalies.

Temperature. Temperature will hasten just about any chemical reaction and corrosion is just that, a chemical reaction. So the higher the temperature, the faster will be the corrosion.

How will you explain the statement ‘we cannot see the objects in a dark room’?

Answer»

"We can see only those objects which REFLECT light back to our eyes.

For seeing an object there MUST be some source of light HOWEVER feeble or strong it may be, and the object must reflect that light back to our eyes to be seen.

In a dark room where there is no light, even if there are objects, it won’t return any light our eyes DUE to lack of source of light.

Hence we cannot see anything in a dark room.

The iron knife shines better after cutting the sour fruits like lemon, raw mangoes. Why?

Answer»

Sour FRUITS like lemons, raw mangoes contain organic ACIDS. These fruits usually contain citric acids in them.

Citric acid is a weak acid. It acts as a chelating agent on TRACE metals like iron.

When iron comes in CONTACT with this type of acids, they react with them. This gives the iron KNIFE more shine on reaction with those acids.

Which uses more energy 250W TV set in 1 hour or 1200W toaster in 10minutes

Answer»

For T.V SET

Power (P) = 250w, Time (t) = 1hr=60×60=3600s

For TOASTER

Power (P) = 1200w, Time (t) = 10min=10×60=600s

We know that Energy (E) = P×t

∴ Energy consumed by a TV set = 250 × 3600 = 9 × 105J

∴ Energy consumed by a toaster = 1200 × 600 = 7.2× 105J

∴ the energy consumed by a 250 W TV set in 1 H is more than the energy

consumed by a toaster of power 1200 W in 10 minutes.

Answer»

Plastids are double-membrane organelle which might be discovered inside the cells of plant life and algae. Plastids are accountable for manufacturing and storing of food. thoseoften includes pigments which are used in photosynthesis and one-of-a-kind styles of pigments which can trade the coloration of the mobile.styles of Plastids are

Chloroplasts
Chromoplasts
Gerontoplasts
Leucoplasts

Chloroplasts– Chloroplasts are the most regarded plastids which can beresponsible for photosynthesis. these are protected with thylakoids wherein the manner of photosynthesis happens.
Chromoplasts– is a call given to a place for all of the pigments to be storedand synthesized within the plant. those can be usually located in flowering vegetation, growing older LEAVES and culmination. Chloroplasts convert into chromoplasts. Chromoplasts are carotenoid pigments that permit distinctivecolorings which you SEE in leaves and end result. the main reason for its structure and the color for attracting pollinators.
Gerontoplasts – those are essentially chloroplasts that goes with the getting older process. Geronoplasts refers back to the chloroplasts of the leaves that facilitatesthe beginning to transform into one of a kind other organelles when the leaf is no longer the use of photosynthesis usually in autumn month.
Leucoplasts – these are the non-pigmented organelles that are colorless. they may be usually FOUND in most of the non-photosynthetic elements of the plant like roots. They acts as a storage sheds for starches, lipids, and proteins depending at the desires of plant. they are ordinarily used forconverting amino ACIDS and FATTY acids.
