Answer: (a) wet marble floor, dry marble floor, newspaper and towel

Explanation:

Friction DEPENDS on the roughness of a surface. This means that the rougher the surface is, the more friction will be exerted.

Rough Surface ⇒ More Friction

SMOOTH Surface ⇒  Less Friction

This is because, on a rough surface, there are MANY irregularities present.

A Marble floor is very smooth. If it is wet, it becomes more smooth as water INCREASES smoothness.

So, the force of friction acting on a wet marble floor is the least, followed by a dry marble floor.

Newspaper and towel both are relatively rough surfaces but newspapers have fewer irregularities. If you closely observe a towel, you will find that its surface is less smooth than a newspaper.

So, the force of friction on a newspaper will be less than on a towel.

BASES that are soluble in water are called ALKALIS. But bases like COPPER hydroxide Cu(OH)2 ferric hydroxide (Fe(OH)3) aluminium hydroxide (Al(OH)3)do not dissolve in water. They are, therefore, not alkalis.

Answer:

The boiled egg normally has more DENSITY than water and thereby it sinks. However, if salt is added to the water, then it BECOMES denser and in such cases, the egg floats in the water.

So, from this, we can conclude that Mary was trying to test it USING water that had high salt concentration. However, Vakula made it sink by changing the water by LOWERING the salt concentration.

Explanation:

1..Answer.

The surroundings where plants and animals live, is called their habitat. For example, the habitat of a frog is fresh water, while the habitat of a camel is a desert.

2.. Answer

A cactus is able to survive in the desert due to the following features:

(i) It has long ROOTS that go deep inside the soil for absorbing water.

(ii) Its leaves are in the form of spines to prevent water loss through transpiration.

(iii) Its STEM is covered with a thick waxy layer to retain water.

3.. Answer

a) The presence of specific features, which enable a plant or an animal to live in a particular habitat, is called adaptation.

(b) The habitats of plants and animals that live on land are called terrestrial habitat.

(c) The habitats of plants and animals that live in water are called AQUATIC habitat.

(d) Soil, water, and air are abiotic factors of a habitat.

(E) Changes in our surrounding that makes us respond to them are called stimuli.

4. Answer.

Non-living things are plough, sewing machine, radio, and boat. On the other hand, mushroom, water HYACINTH and earthworms are living things.

5..zAnswer.

Bus is an example of a non-living thing that shows two characteristics of living things. Like the living things, it can move from one place to another and it also requires energy to do work.

6. Among the non-living things listed below, which things were once a part of living things?

Butter, Leather, Soil, Wool, Electric Bulb, Cooking Oil, Salt, Apple, Rubber

Answer.

The non-living things which were once a part of living things are butter, leather, wool, cooking oil, apple, and rubber.

Butter is made from milk, which is obtained from dairy animals.

Leather is obtained from skin of animals.

Wool made from hair of sheep.

Cooking oil is obtained from the seeds of the plants.

Apple is a obtained from tree.

Rubber is obtained from the latex of a tree.

7. List the common characteristics of living things.

Answer.

Some common characteristics of living things are:

Growth

Movement

Energy requirement

Reproduction

Respiration

Respond to stimuli

Excretion

8. Explain why speed is important for survival in the grasslands for animals that live there (Hint: There are few trees or places for animals to hide in grasslands habitat).

Answer.

In grasslands, there are very few trees to hide for animals from predators like lion and tiger. In small grasses, predators can easily locate their prey. So, these animals have to run fast to reach a safe place and escape from their predators. Thus, speed is important for survival in the grasslands for animals that live there.

PLEASE MAKE MY ANSWER AS BRAINLIEST PLEASE

Answer:

positive magnification means upright image with respect to object

negative magnification means inverted image with respect to object.

magnification greater than 1 means image SIZE is larger than object size

and magnification less than 1 means image size is less than object size.

In case of convex MIRROR image is always reduced in size and upright, so 0

In case of concave mirror image is inverted-small, inverted large, upright-large, so m>1 and m<0

real image is only formed by concave mirror and possible results are inverted-small or inverted large image, So, m<0

Virtual image formed by concave mirror is upright-large, while virtual image formed by convex mirror are upright-small. So, m>0

So, correct match is

A-2,3

B-2,3

Answer:

Mercury is the only one in the LIQUID STATE at room temperature. It's USED in thermometers because it has a high coefficient of expansion. Hence, the slightest change in temperature is notable when it's used in a thermometer. It also has a high BOILING point which MAKES it very suitable to measure higher temperatures.

ANSWER:

For many solids dissolved in liquid water, the solubility increases with TEMPERATURE. The increase in KINETIC energy that comes with higher temperatures ALLOWS the SOLVENT molecules to more effectively break apart the solute molecules that are held together by intermolecular attractions.
