Asatellite s travels in a circular orbit around the earth. a rocket is located at the apogee of its elliptical orbit for which = 0.58. (a) determine the sudden change in speed that must occur at a so that the rocket can enter the satellite’s orbit while in free flight along the blue elliptical trajectory. (b) when it arrives at b, determine the sudden adjustment in speed that must be given to the rocket in order to maintain the circular orbit.
true. the question describes the idea of energy conservation faithfully. energy can change forms but remains the same within an isolated system over time. within such a system, energy cannot be created or destroyed.
correct answer is which is not any option
in this question we have given,
force on piston 1,=6600n
area of piston 1,=
force on piston 2,=9900n
we have to find area of piston 2, =?
according to pascal's law, the pressure is transmitted with equal intensity to every part of the fluid:
in equation 1
as we know that collision is elastic so we will have
also we can use momentum conservation
now from above two equations we will have
also we have
so both balls will separate after collision and move in opposite direction as the final velocities are opposite in sign
so correct answer will be
d. the balls separate and move in opposite directions.
