Q.1 Why do porters place a round piece of cloth on their heads when they carry heavy loads ? Q2.Explain why wooden sleepers are kept below the railway line.Q3 Why is it easier for camels to run in desert?Q4.Two cubical blocks of the same dimensions, one of wood and the other made of iron, are kept on sand. Which one will exert greater pressure and why?Q5.Two rods of the same weight and equal length have different thickness. They are held vertically placed on the surface of sand, as shown in the figure. Which one of them will sink more? Why?​

Answer»

1) Porters place a round piece of cloth on their head when they carry heavy lods as the round piece of cloth increases the area on which the load is placed. We know that when surface is more than pressure is less. As a result, the pressure on their heads get reduced.2) Wide wooden sleepers are kept below railway lines because the area of wooden sleeper is large . we know that large area less pressure . Wooden or concrete sleepers are kept below the railway line so that there is less pressure of the train on the ground and railway line may not SINK into the ground3) Camel can run on sand easily because they have wide feet which HELP them to balance thier weight on LOOSE sand and wider feet gives a larger surface area also. 4) The wood will exert a great pressure. 5) The thin ROD will sink first because it has less surface area so it will execrt more pressure on sand than the thicker rod.plz MARK me as a brainiliestand plz follow me!!

pls answer if u know.. because sometime u answer wrong.. and one who know correct answer cannot so.. pls.. if u do so ur answer will be reported..pls answer any 10 if u know.. 0ps open image then answer.. Thankyou ​

contact forces are the forces acting on a body by a physical contact or a touch... example such as the force of collision between two bodies... and force exerted by a compressed spring. non contact forces are the forces which are applied on a body without any physical contact or touch ..example = electrostatic force, force of gravity and MAGNETIC forces... ANS 2) bags and suitcases are provided with broad handles because more the area of contact lesser will be the force or weight that is it will be easier for us Carry the bag and the suitcase if the force exerted by the bag on our shoulders is less .... ans 4) the factors are humidity and moisture of that place... ans 5) when two like CHARGES are brought in contact it repels like if the North pole of one magnet is brought near the North pole of another magnet it repels.... now if two unlike charges are brought in contact then it attracts like if the South pole of a magnet is brought near the North pole of a magnet then it attracts.. ans 7) mass weight the mass of a the weight of a body is the body is the quantity amount of mass contained of matter contained in the body.... its si unit is in it.. it's si unit is Kg. Newtonans 8) when we climb up in higher altitudes our blood pressure increases there due to high blood pressure nose starts bleeding. The main concept here is that pressure decreases with INCREASE in altitude..ans 9 ) when a solid is kept at a SURFACE it exerts pressure only at its base due to its weight.. but a liquid exerts pressure in all sides and all directions of the container in which it is kept.. it is due to the thrust exerted by the liquid.. ans 10) the pressure will decrease as the area is doubled.the answers which I knew I did those ..plz mark me as brainliest for all these work...

How to calculate slope for uniform motion in distance time graph ?

Answer» TION:The slope of the line on a POSITION versus time graph is equal to the velocity of the object. If the object is moving with a velocity of +4 m/s, then the slope of the line will be +4 m/s. If the object is moving with a velocity of -8 m/s, then the slope of the line will be -8 m/s. If the object has a velocity of 0 m/s, then the slope of the line will be 0 m/s. The slope of the line on a position versus time graph tells it all. Because of its importance, a student of physics MUST have a good understanding of how to calculate the slope of a line. In this part of the lesson, the method for determining the slope of a line on a position-time graph will be discussed.Hope it helps you and Mark me as Brainliest please.

Explain why objects moving in Fluids must have special shapes ?

Answer»

When a BODY moves through a fluid, it experiences an opposing force which TRIES to oppose its motion through the fluid. The opposing force is known as drag force. This FRICTIONAL force depends on the SHAPE of the body. By GIVING objects a special shape, the force of friction acting on it can be minimised. Hence, it becomes easier for the body to move through the fluid.HOPE IT!S HELP YOU......PLEASE MARK ME AS BRAINLISTS......

Explain the construction and working of a thermos flask?​

Answer»

It is constructed in such a way that heat loss due to conduction,convection and RADIATION is minimized. It is a double walled bottle of thin glass and the space between the walls is evacuated. The mouth of the bottle is closed by a cork or plastic stopper.A thermos is a bottle with a double-walled container inside of it. The air between the two walls is SUCKED out during construction, creating a vacuum. Instead of CONTAINING some kind of heating element to keep hot things hot, a thermos is DESIGNED to keep hot things hot by not ALLOWING heat to escape.

Why are electromagnetic magnets temporally magnets

Answer»

On the other hand, the north end of one magnet will REPEL the north end of the other (and similarly, south will repel south). An electromagnet is the same way, EXCEPT it is "temporary" -- the magnetic field only exists when ELECTRIC current is flowing. ... This on-demand MAGNETISM is what makes the electromagnet so useful.Explanation:
