0Thank You

Gaurav Seth 7 years, 1 month ago

Let "t" = time after which both stones meet

"S" = distance travelled by the stone dropped from the top of tower

(100-S) = distance travelled by the projected stone.
◆ i) For stone dropped from the top of tower

-S = 0 + 1/2 (-10) t²

or, S = 5t²
◆ ii) For stone projected upward

(100 - S) = 25t + 1/2 (-10) t²

= 25t - 5t²

Adding i) and ii) , We get

100 = 25t

or t = 4 s
Therefore, Two stones will meet after 4 s.
◆ ¡¡¡) Put value of t = 4 s in Equation i) , we get

S = 5 × 16

= 80 m.
Thus , both the stone will meet at a distance of 80 m from the top of tower.

Aman Naithani 7 years, 1 month ago

Nitrogen cycle - the nitrogen in atmosphere in N2 firm get converted into its oxides NO3 &NO3 ( NITROGEN FIXATION) by industries ,some bacteria ( rizobium , azatobactor)and by lightning .The NO2 AND NO3 are absorbed by plants and makes many nitrogenous compounds (proteins , amino acids etc) these compounds goes to animals when they eat it and it comes out when they excreate. In soil, bacteria converts this NO2 AND NO3 into ammonia(NH4) (AMMONIFICATION) this ammonia tends to N2 FIXATION BY SOME BACTERIAS and by DENITRIFIACTION NO2 AND NO3 GET converted into N2 again

Derivation of all laws of newton

Posted by Harman Singh 7 years, 1 month ago

CBSE > Class 09 > Science

2 answers

Sirsti Sngm 7 years, 1 month ago

Newton's first law of motion : Law of inertia which states that if a object is at rest it will remain at rest and if an object is in motion it will remain in motion untill an external force is applied on body. Newton's second law of motion : Rate of change of momentum is directly proportional to the applied force and takes place in the direction in which the force acts. It gives relation between force and acceleration and tells that : Force is the product of mass and acceleration (F=m×a) Newton's third law of motion :To every action there is equal and oppossite reaction.
