Speed = (distance traveled) / (time to travel the distance).
Strange as it may seem, 'velocity' is completely different.
Velocity doesn't involve the total distance traveled at all.
Instead, 'velocity' is based on 'displacement' ... the distance
between the start-point and end-point, regardless of the route
taken to get there. So the displacement in driving once around
any closed path is zero, because you end up where you started.
Velocity =
(displacement during some time)
divided by
(time for the displacement)
AND the direction from the start-point to the end-point.
For the guy who drove 15 km to his destination in 10 min, and then
back to his starting point in 5 min, (assuming he returned by way of
the same 15-km route):
Speed = (15km + 15km) / (10min + 5min) = (30/15) (km/min)
= 2 km/min.
Velocity = (end location - start position) / (15 min) = Zero .
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: mechanical energy
Explanation: I hope this helps! Also, please mark as brainliest, thanks!
Transverse waves travel on a direction that is perpendicular to the motion of the particles (or whatever medium is waving) So the particles must be moving east to west, which is transverse to the north-south motion of the wave
False.
Gravity changes depending on latitude, as well as height above sea level.
