Answer:

3529 km/h west

Explanation:

The average velocity is given by:

v=\frac{d}{t}

where

d is the displacement

t is the time taken

For the plane in this problem, we have:

d=15.0 km

t=15.3 s \cdot \frac{1}{3600 s/h}=0.00425 h

Therefore, substituting into the formula,

v=\frac{15.0}{0.00425}=3529 km/h

and the direction is the same as the displacement (west).

What happens to the object if the line crosses the x-axis from the positive portion of a velocity versus time diagram?
stealth61 [152]

Answer:

A velocity time graph shows the change of velocity of an object with respect ot time. If the slope of the graph is increasing in the postive region, it means that the velocity is changing, if the slope is decreasing, it means the the velocity is decreasing, but the object is moving in the same direction (positve direction).

If this slope intersects the graph at x-axis, it means that the body has 0 velocity and has become still. After that, if the line enters in the negative region, it means that its velocity is started to increases again, but the body is movinging in the opposite direction (negative direction)

Explanation:


In many North American rivers, populations of various kinds of non-native cyprinid fishes are present, including black carp, grass carp, bighead carp, silver carp, common carp, and goldfish. All six of these classes are found in the Mississippi River basin and following their aggression has shown complex, especially where wealth is low. The bighead carp is a species of freshwater fish, one of several Asian carps. It is one of the most intensively exploited fishes in aquaculture, with a yearly global product of over three million tonnes in 2013, mostly from China.

What is the relationship of human beings to time ?
aalyn [17]

The Relationship with Time: When you focus on time and you focus on something you can't control, it creates stress. When you focus on time and you focus on something you can't control, it creates stress. We need to focus on the things that we can control and then we bring our best energy.
