Question

Velocity of efflux in Torricelli's theorem is given by v equals square root of 2 g h end root, here h is the height of hole from the top surface, after that, motion of liquid can be treated as projectile motion. What is its time of fall of liquid on the ground?

  1. fraction numerator 1 over denominator square root of 2 end fraction s    
  2. fraction numerator 1 over denominator square root of 3 end fraction s    
  3. fraction numerator 1 over denominator square root of 5 end fraction s    
  4. square root of 2s    

The correct answer is: fraction numerator 1 over denominator square root of 5 end fraction s



    H equals 2 s i n invisible function application 30 to the power of ring operator end exponent equals 1 m therefore t equals square root of fraction numerator 2 H over denominator g end fraction end root equals fraction numerator 1 over denominator square root of 5 end fraction s

    A glass full of water is placed on a weighing scale, which reads 10 N. A coin with weight 1 N is gently released into the water. At first, the coin accelerates as it falls and about halfway down the glass, the coin reaches terminal velocity. Eventually, the coin rests on the bottom of the glass. Acceleration due to gravity is 10 m divided by s to the power of 2 end exponent. The scale reads

    Changing from a circular to An elliptical orbit Let us identify the system as the spacecraft and the Earth but not the portion of the fuel in the spacecraft that we use to change the orbit. In a given orbit, the mechanical energy of the spacecraft – Earth system is given by E equals negative fraction numerator G M m over denominator 2 r end fraction This energy includes the kinetic energy of the spacecraft and the potential energy associated with the gravitational force between the spacecraft and the Earth. If the rocket engines are fired, the thrust force moves the spacecraft through a displacement. As a result, the mechanical energy of the spacecraft – Earth system increases. The spacecraft has a new higher energy but is constrained to be in an orbit that includes the original starting point. It can not be in a higher energy circular orbit having a larger radius because this orbit would not contain the starting point. The only possibility is that the orbit is elliptical as shown in the figure.
