Let us first know the given: Tennis ball has a mass of 0.003 kg, Soccer ball has a mass of 0.43 kg. Having the same velocity at 16 m/s. First the equation for momentum is P=MV P=Momentum M=Mass V=Velocity. Now let us have the solution for the momentum of tennis ball. Pt=0.003 x 16 m/s= ( kg-m/s ) I use the subscript "t" for tennis. Momentum of Soccer ball Ps= 0.43 x 13m/s = ( km-m/s). If we going to compare the momentum of both balls, the heavier object will surely have a greater momentum because it has a larger mass, unless otherwise the tennis ball with a lesser mass will have a greater velocity to be equal or greater than the momentum of a soccer ball.
Answer:
it's B. circuit a and b are series circuit while c is parallel
Answer:
D. gravity
Explanation:
Gravity keeps the atmosphere from escaping into space.
Explanation:
Given that,
Diameter = 10 cm
Distance = 2 m
Speed 
Speed 
Pressure in main pipe 
(I). We need to calculate the diameter
Using equation of continuity
(II). We need to calculate the pressure the gauge pressure
Using Bernoulli equation
(III). If it is possible to carry water to a faucet 17 m above ground,
Using Bernoulli equation
Here, 
Put the value in the equation
Hence, This is required solution.
Answer:
Gravity separation is an industrial method of separating two components, either a suspension, or dry granular mixture where separating the components with gravity is sufficiently practical: i.e. the components of the mixture have different specific materials and Magnetic separations take advantages of natural magnetic properties between minerals in feed. The separation is between economic ore constituents, noneconomic contaminants and gangue. and saw dust can be separated by gravity separation method. The process can be used for separating insoluble substances which are heavier than liquid by allowing them to settle down on their own due to gravity. The mixture of sand and iron can be separated from each other by using a magnet. Iron gets attracted towards a magnet leaving behind the sand.
