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:
East component is: 18.64 m/s
Explanation:
If the resultant is 32.5 m/s directed 35 degrees east of north, then we use the sin(35) projection to find the east component of the velocity:
East component = 32.5 m/s * sin(35) = 18.64 m/s

Answer:
Distance covered by the sound in air is 800 meter and the time taken by the sound in water for the same distance is 0.5 seconds.
Explanation:
Given:
Speed of sound in air = 320 m/s
Speed of sound in water = 1600 m/s
Time taken to reach certain distance in air = 2.5 sec
a.
We have to find the distance traveled by sound in air.
Distance = Product of speed and time.
⇒
⇒
⇒ meters.
b.
Now we have to find how much time the sound will take to travel in water.
⇒ Time = Ratio of distance and speed
⇒
⇒ <em> ...distance = 800 m and speed = 1600 m/s</em>
⇒
⇒ seconds.
Distance covered by the sound in air is 800 meter and the time taken by the sound in water for the same distance is 0.5 seconds.
A machine that provides both constant speed and maximum resistance throughout the full range of motion provides an isokinetic type of muscular contraction. This type of contraction occurs when the muscle would contract and shorten at a consistent and constant speed. To have this contraction, special equipment are to be used. An example of an equipment would be an <span>Isokinetic Dynamometer. </span>However, this type of training is said to be one of the fastest in increasing the muscle strength and the muscle endurance. With this training, the muscles being targeted would gain strength consistently and evenly throughout the whole duration of exercise.
