Forces, Gravitation, Waves and Sound these are AMONG the easiest of all chapters in terms of understanding, however all of the other chapters introduce some nice NEW CONCEPTS which can be a bit difficult at first.

because it is strong....and it has thread work which HELP in adhere ACTION....and ALSO friction force comes into PLAY...keeping the PLATES intact

The direction of the electric FIELD is the direction that a POSITIVE charge would accelerate if it were placed there. A negative charge would accelerate in the opposite direction. These things were DETERMINED by producing electrically charged objects and MEASURING which WAY they move :)

m/secBut DOWNWARD in DIRECTION

When insulating materials rub against each other, they may become ELECTRICALLY CHARGED . ELECTRONS , which are negatively charged, may be 'rubbed off' one material and on to the other. The material that gains electrons becomes negatively charged.Hope it HELPS:)

the PRODUCTION of OFFSPRINGS by ASEXUAL or SEXUAL REPRODUCTION

The property with which a matter is able to form dipoles instantaneously is KNOWN as Polarizability. There is a CLASSICAL theory on this polarizability. This theory states that EVERY matter is made up of molecules which are further broken into ATOMS and the atoms are constructed of electrons, protons and NEUTRONS.

Ohm's LAW states that the electrical current (I) flowing in an circuit is PROPORTIONAL to the voltage (V) and inversely proportional to the resistance (R). Therefore, if the voltage is INCREASED, the current will INCREASE PROVIDED the resistance of the circuit does not change.

Given:Radius of Earth decreases by 50%. But mass remains constant.To find:If there will be decrease in weight of a body by 25%. (True or False)Concept :Gravitational acceleration is ACTUALLY a FIELD INTENSITY .Calculation:Now, new mass is still M , butnew radius is r/2 (because radius decreases by 50%)Let new gravity be g2Since gravitational acceleration BECOMES 4 times , so the weight of any body on the surface of the Earth will also become 4 times.So the given STATEMENT is false.

the VALUE of x is 3/2Explanation:As we know the relation between LINEAR expansion, SUPERFICIAL expansion and volume expansion is GIVEN asso we can say thatnow from above equationsso the superficial expansity is 2/3 TIMES the cubic expansityso the value of x is 3/2 #LearnTopic : Thermal expansionbrainly.in/question/8451989

A. will be CORRECT ANSWERS

________❤In CASE of gases, when balloon is partially inflated in a COOL room it EXPANDS to full size when put in warm water. This all is due to thermal EXPANSION. So, increase in DIMENSION of a body due to increase in temperature is thermal expansion. The expansion in length is called linear expansion.❤_________________

As you MAY have KNOWN that a PLANE mirror FORMS a virtual and erect IMAGE of the same size as the object is so the height of image will be same as the height of object.

i...... this is your ANSWER......HOPE it will be HELPFUL....

I = 0.5mAExplanation:R = 5+5+10 = 20 ohmV= IR10 = I × 20I = 10/20I = 0.5mA

The foundation of the BUILDING is generally built wider and broader as compared to its walls so that the building does not sink into the ground and is ALSO CAPABLE to handle the pressure of the entire building. With the wide base as the foundation, LARGE buildings can prevent HIGH pressure

1/F=(n-1)(1/R1-R2)ANSWER

when both the FORCES on the LHS and on the RHS are EQUAL.

ans is option (C) Explanation: because when placed at c the IMAGE is of the same size and on the same SIDE of mirror .It is also REAL and inverted

The Potentiometer is an electric instrument that used to measure the EMF (electro MOTIVE force) of a given cell, the internal resistance of a cell. And also it is used to COMPARE EMFs of different CELLS. It can also use as a variable resistor in most of the applicationsThe potentiometer is a simple DEVICE used to measure the electrical potentials (or compare the e.m.f of a cell). One form of potentiometer is a uniform high-resistance wire attached to an insulating support, marked with a LINEAR measuring scale.

Explanation:2kHz = 20,000Hz                 35CM = 0.35mv=fλ (wavespeed = frequency x wavelength): V = 20000 x 0.35 = 7000 ms^1s=d/t (SPEED = distance/time) rearranges to give t=d/s: 7000/1500 = 4.67s (3 s.f)

l the forces that act UPON an object are balanced , then object is SAID to be equilibrium, Balanced is the KEY WORD that is used to describe equilibrium situation.
