Write the 10thing which are rest and in motion at railway station

Answer»

This question is conceptually wrong.

Rest and motion are relative terms.

The thing which appears as rest according to ONE can ALSO be in motion according to other.....

Write the largest and smallest practical unit of mass?

Answer»

Answer:

The unit of mass in SI units is kilogram (KG). The largest practical unit of mass is Chandrasekhar limit (CSL). 1 CSL = 1.4 TIMES the mass of sun. Atomic or NUCLEAR MASSES are made in terms of a unit CALLED amu (atomic mass unit)

5.

State the law of conservation of momentum and derive its expression

Answer»

The mass of two bodies are m1 and m2 INITIAL velocity of two bodies are u1 and u2 Final velocity of both the bodies are v1 and V2 Acceleration=a1 and a2 respectively Firstly two bodies moving with initial velocity Then when collision TOOK place they apply equal and opposite force so the force becomes F1 and F2 After collision they started moving with the final velocity FIRST BODY Initial velocity = u1 Final velocity = v1 a1=(v1-u1)/t F1=m1(v1-v2)/t SECOND BODY a2=(v2-u2)/t F2=m2(v2-u2)/t F1=-F2 m1(v1-u1)/t= -m2(v2-u2)/t m1v1-m1u1=m2v2+m2u2 m1v1+m2v2=m1u1+m2u2 Total momentum after collision = Total momentum before collision According to conservation of momentum , momentum can neither be created nor be DESTROYED........

6.

Work done by the force of gravity when a body is lifted to height h above the ground is positve or negative

Answer»

It is in UPWARD DIRECTION but force of gravity ALWAYS act in the DOWNWARD direction so it is negative
plz mark my ans as brainliest if it is HELPFUL to u

7.

The effect of gravitationis more in liquid than solid.Why?

Answer»

Your question appears directed to the POINT that LIQUIDS react to that forcemore easily than solids. That is because the molecules of liquids are not as tightly bound together as insolids. ... GRAVITATIONAL FORCE DEPENDS only on mass and distance.

Why wire offer resistace for current in connected to cell?

Answer»

When wire is connected to a cell,the charges DRIFTING in it COLLIDE continuously.

this resists the charges from drifting smoothly.
thus wire OFFERS current when connect to wire.

but at 0 KELVIN the RESISTANCE is zero.

find the ratio of distance and displacement when a car completes 3.5 rounds of circular track of radius 100m

Answer»

Its DISTANCE is 3.5*(2πr).
=7πr metre
=700π m

its DISPLACEMENT is distance of final positions and INITIAL position.
ie. 2r=2*100=200m.
so ratio=700π/200=3.5π

What do you mean by electro magnetic induction

Answer»





HomepagePhysics Article

Electromagnetic Induction

What is Electromagnetic Induction?

Electromagnetic Induction is a current produced because of voltage production (electromotive force) due to a changing MAGNETIC field. This either happens when a CONDUCTOR is PLACED in a moving magnetic field (when USING ac power source) or when a conductor is constantly moving in a stationary magnetic field.

This phenomenon was discovered by Michael Faraday. He arranged a conducting wire as per the setup given below, attached to a device to measure the voltage across the circuit. When a bar MAGNET was moved through the coiling, the voltage detector measures voltage in the circuit.

29.

Which instrument is use for determination of degree of stability or instability of an air parcel?

Answer»
  1. The vertical distribution of the surrounding TEMPERATURE is measured.

    The AIR parcel is left to rise in the atmosphere.

    If the temperature inside the parcel is lower than the surrounding temperature meaning the parcel is denser than the surrounding air thus it falls hence the air is stable.

    If the parcel is less dense than the surrounding air it rises and thus it SHOWS that the surrounding air is unstable.

    If the surrounding temperature is EQUAL to the temperature of air inside the parcel the air stability is NEUTRAL.

    The instrument is thus an air parcel.
30.

37.

Which one of the fallowing instrument is used for determination of degree of stability or instability of an air parcel?

Answer»

The vertical distribution of the surrounding temperature is measured.

The AIR parcel is left to rise in the atmosphere.

If the temperature inside the parcel is lower than the surrounding temperature meaning the parcel is denser than the surrounding air THUS it falls HENCE the air is stable.

If the parcel is less DENSE than the surrounding air it rises and thus it shows that the surrounding air is unstable.

If the surrounding temperature is equal to the temperature of air inside the parcel the air STABILITY is neutral.

The instrument is thus an air parcel.

39.

When a cell is fully turgid which pressure is zero?

Answer»

When a cell is fully turgid, its OP is equal to TP and DPD is zero. Turgid cells cannot absorb any more WATER. Thus, with reference to plant cell, the DPD can be DESCRIBED as ACTUAL thirst of cell for water and can be expressed as DPD=OP-TP. When DPD is zero, entry of water will stop.
