Answer:
<em>The direction of ball will be Number 4 (as can be seen in attached picture) ---- the path of ball will be making some angle when it leaves the tube. </em>
Explanation:
The question is incomplete. So the picture, which is missing in question, is attached for your review.
As it can be seen in the picture, the ball coming out of the tube will have two components of velocity. One is along the length of tube (because ball is moving in that direction and is coming out from the hole), other is velocity component will be perpendicular to the tube (because the ball is made to move in that direction as the tube is rolling on the surface).
<em>So, taking the resultant of two vectors of velocity, the resultant direction of ball will be Number 4 (as can be seen in attached picture) ---- the path of ball will be making some angle when it leaves the tube. </em>

Answer: True
Explanation: The amount of natural gas supplied in the residential area has lesser cost as compared with the electric power industry. The cost is lesser for the natural gas because it is abundantly available resource in the environment and electricity is generated by several methods and thus supplied so there is more effort and resources required and this costs more .Therefore, natural gas is cheaper as compared with electric power .
Answer:
B) P1 would increase to maintain the flow rate ( correct )
C) The resistance would increase (correct )
Explanation:
flow rate = 10 liters per minute
Driving pressure (p1) = 20 cm H20
Fixed downstream pressure (p2) = 5 cm H20
The correct statements when we pinch the Lumen in the middle of the tube would be : P1 would increase to maintain the flow rate and The resistance would increase.this is because when we pinch the Lumen we reduce its diameter and the reduction of its Diameter will result to increased resistance against the flow and resistance of flow is directly proportional to pressure hence P1 would increase as well
The wrong statement would be : The flow would decrease
