@ akarsh kindly be precise while asking the question , let me know which part in gravitation u have doubt , so, that i can able to explain it here . and as you are inj class 9 , there is not much in...
@ arun both formula are nearly same , both defines the formula for buyoncecy , the only thing that u need to understand is that we use h = pdg in the case of gas where volume expansion takes place ,...
Draw fbd and write forces , you will find these equations 150-T1=15a T1-10-T2=10a T2-50=5a add all three equation. a=3m/s^2 T1=105N, T2=65N
@ mohammed be specific in your query , can i know which pattern you are asking about ?? is it the jee exam pattern or +2 science board exam pattern ?? kindly conform me the same . if jee , then he...
@ ankur kindly elaborate the ques . what kind of help u required ?? if u have any kind of doubt in any chapters , then let me know , or if u not able to solve any ques then post that ques here , we...
@ anirudhh yes , u can make it out but that 15 days u have to work hard , as far as i knws fiitjee will ask the foundation ques from ncert . and in our times , the ques was of term 1 level , but at...
@ preeti yes , that happens , actualy when she is reading the msg the same will be directly referred to the customer support team member . and dnt worry they will keep in touch with you as soon as...
Since the cannon is placed on a smooth surface , after firing it will recoil , thus apply the conservation of momentum to find the velocity of the cannon. Mass of cannon x velocity of cannon = mass...
Taking gravity = 10m/s^2 Lets first find out the change in velocity of the ball while its in contact with the ground . So , Let Velocity of the ball just before contact with the ground = v1 applying...
Its same as ratio of their masses . Since inertia is directly proportional to mass. So mass of father / mass of son = 50/30 = 5/3
Applying the formula v = u + at , we can see the ball will reach its maximum height at t=6 secs if we take g = 10 m/s^2 . Then apply the formula v2= u2 + 2 a S to determine total displacement , whose ...
Assuming they are equally spreaded along the axis, ratio of inertia = ratio of masses = 2:1

Dear student No. Because the force applied by the bird to take off would be transferred to the surrounding air and not on the cage. Since no force is applied on cage no change of weight is observed
Let T is the time period and r is the distance between the earth and the sun. Then, by Kepler’s law T 2 ∝r 3 => T∝r 3/2 => 365days ∝ r 3/2 ..............(1) When r becomes r/2 So new time period, T’...
Assume that it is moving upside of the inclined plane having an angle thetha. and then after just balance the forces in inclined direction. Therefore, Net force mgsinthetha - umgsinthetha =...
From top let the ball meets at a distance x then, x = 0 + 0.5gt^2...................(1) From the ground, 100-x = 25t – 0.5gt^2..................(2) solve the two eqns. and get the values of x and t.
1.Volatile(escaping nature of liquid to become vapour) substance has very low Boiling point and generally takes place at room temperature,Its a fast process and generally seen in liquid state....eg...
Hi 1.Anthracnose 2.Verticillium Wilt
Yes.Higher is the boiling point lower is the rate of transformation of liquid to gas. Please approve if it helps.
Sonora 64 is a high breeding variety of wheat generated by Norman E Borlaug. This plant variety was introduced to India after manipulating it by gamma radiation. The resulted wheat variety was called ...
Hence the ratio of time taken by two planets to make one revolution around the sun will be root8 : 1
@ sahil In 9 th class , to become a topper is so easy within your class level . in this class only u hv to clear the foundation for JEE / NEET , exam . and donot take stress from now and budern your...
