According to the law of conservation of energy, the potential energy is converted to kinetic energy. Remember, potential energy is calculated using height and weight. If the ball is on the ground, height is 0.
Answer:
The value of gauge pressure at outlet = -38557.224 pascal
Explanation:
Apply Bernoulli' s Equation
+ 
+ 
= 
+ 
+ 
--------------(1)
Where
= Gauge pressure at inlet = 3.70105 pascal
= velocity at inlet = 2.4 
= Gauge pressure at outlet = we have to calculate
= velocity at outlet = 3.5
= 3.6 m
Put all the values in equation (1) we get,
⇒ 
+ 
= + 
+ 3.6
⇒ 0.294 = + 0.6244 + 3.6
⇒ = 0.294 - 0.6244 - 3.6
⇒ = - 3.9304
⇒ = - 38557.224 pascal
This is the value of gauge pressure at outlet.
1) The coefficient of friction of the surface
2) The weight of that objects
Saturn is the second largest planet in our solar system. At an average distance of 800 million miles (1.3 billion kilometers) from Earth, Saturn is the farthest planet that can be seen without a telescope. Saturn is the sixth planet from the sun. Because Saturn is so far away from the sun, Saturn is considered one of the outer planets. Despite it's large size, Saturn is the least dense planet in our solar system!
The right answer for the question that is being asked and shown above is that: "D) The magnetic north and south poles of Earth are interchanged." The statement that best describes an effect of changes in Earth's magnetic field is that D) The magnetic north and south poles of Earth are interchanged.<span>
