A spacecraft consumes more fuel in going from earth to moon than it takes for a return trip. Comment on this statement.

Statement I: It takes more fuel for a spacecraft to travel from the earth to the Moon than for the return trip. Statement II: The point of zero gravitational field intensity due to the earth and the Moon is lying nearer to the Moon, i.e., in the diagram shown, for rltr_(0), E_(g) is towards the earth's centre and for rgtr_(0), E_(g) is towards the Moon's centre and at r=r_(0),E_(g) is zero.

During the journey of space ship from earth to moon and back, the maximum fuel is consumed :-

An unmanned satellite A and a spacecraft B are orbiting around the earth in the same circular orbit as shown. The spacecraft is ahead of the satellite by some time. Let us consider that some technical problem has arisen in the satellite and the astronaut from B has made it correct. For this to be done docking of two ( A and B ) is required (in layman terms connecting A and B ). To achieve this, the rockets of A have been fired in forward direction and docking takes place as shown in the figure below: Take mass of the earth =5.98xx10^(24)kg Radius of the earth =6400 km Orbital radius =9600km Mass of satellite A=320 kg Mass of spacecraft =3200 kg Assume that initially spacecraft B leads satellite A by 100s , i.e., A arrives at any particle position after 100 s of B’s arrival. Based on the above information answer the following questions The initial total energy and time period of satellite are, respectively,

Based on the above information answer the following questions. After once returning to the original point, i.e., the place from where the rockets have been fired, in which direction and with what extent the rockets have to be fired from the satellite to again come back in the original orbit?

Based on the above information answer the following questions. To dock A and B in the above-described situation, one can use the rocket system of either one, i.e., either of A or of B . To accomplish docking in the minimum possible time which is the best way?

Statement I- The area of the curve y=sin^2 x "from" 0 "to" pi will be more than that of the curve y=sin x "from" 0 "to" pi . Statement II - x^(2)gtx, if xgt1 .
