When a steadily flowing gas flows from a larger diameter pipe to a smaller diameter pipe the pressure does not decrease, it increases, do to the smaller volume.
Answer
given,
mass of the solid door = 22 Kg
dimension of door = 220 cm x 91 cm
moment of inertia about the hinge
r is the distance from the one edge which is equal to 91 cm or 0.91 m
Moment of inertia about center for rectangular gate is equal to
moment of inertia for rotation about a vertical axis inside the door, 15 cm from one edge
Daniel applies a 30 Newtons force on the ball that sends the ball 300 meters, which gives the work done by Daniel as 9 kJ
<h3>How can the work done be obtained from the given force and distance?</h3>
The given parameters are;
The force with which Daniel hit the ball = 30 Newtons
The distance the ball flew, following the application of the force = 300 meters
Required;
The amount of work done on the ball by Daniel
Solution:
- Work done = Force applied × Distance moved in the direction of the force
Therefore;
The work done by Daniel on the ball, <em>W</em>, can be calculated as follows;
W = 30 N × 300 m = 9000 J = 9 kJ
- The work done by Daniel on the ball is 9 kJ

Answer:
deceleration is the opposite of acceleration
Explanation:
We know that acceleration is the increase of speed with respect to time. So deceleration must be represented on the graph as a decrease in speed over time.a
