when 2 bodies in contact move with respect to each other,rubbing the surfaces, the fric is kinetic.(force is applied).
but when equal force is applied and body is not moving, the fric is static.
so that means co efficient of static fric is greater than that of kinetic fric.
hence kinetic fric is less rhan static fric.
pls rate me if u r satisfied

q ii
FcosQ =mue *N (1)
as there is no change in velocity so no acc
N +FsinQ =mg
N=mg - FsinQ (1)
therefore substitute the value of N in eq 1
so, F= mue mg\cosQ+muesinQ
W=FscosQ
= muemgscosQ\1 +muetanQ
b>
Fminimum =muemg\rooti+mue^2

common types of hybridization are sp, sp3,sp2. spd, spd2, spd3. they all are very simple and are formed due to mixing of orbitals. sp is formed due to merging of 1 s and 1 p orbital, sp2 due to 1 s and 2 p orbitals and so on. for more details check out in OP AGARWALS book for IIT.

we also consider the force that the body acts upon.that force is the weigt and in some cases the horizontal force

along a road lie an odd number of stones placed at intervals of 10 metres.these stones have to be assembled around the middle stone. a person can carry only 1 stone at a time. a man carried the job with one of theend stonesby carrying them in succession.. in carrying all the stones he covers a distance of 3 km. calculate the total numbers of stones

noooooooooo . the value of x changes . suppose x is 45 so at rhs we will get sin1 that is 90 degree.

i think you r being too negative . look at the positive aspects of this site and tou will find a difference. just avoid articles as i do . so bye and take care

consider a 2000kg block kept on the floor. ask 50 kg man to push the block. you will find that the force is been applied ,therefore body is not in equilibrium. so there is some acceleration but there is no movement of the block. so a body can have 0 velocity and non 0 acceleration.
pssssssssss rate me if i m correct
