Eukaryote is an organism whose cells contain a nucleus surrounded by a membrane and whose DNA is bound together by proteins (histones) into chromosomes. Cells of eukaryotes also contain an...

diversity chapters are easy enough , just start with ncert , then move ahead , twice u have to read ncert as its phylum , kingdom and all of its charecteristics u need to remember . after that just...
@ 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.
