Answer:
The average velocity that these birds travel is 122.22 miles per day to the south.
Explanation:
Speed is the physical quantity that expresses the variation in position of an object and as a function of time. In other words, speed is a physical quantity that expresses the relationship between the space traveled by an object, the time used for it and its direction.
Speed is expressed mathematically as the quotient between distance and time:
where "v" is the speed of the mobile, "d" is the distance traveled by the mobile, and "t" is the time taken by the mobile to carry out the movement.
In this case:
- d= 11,000 miles
- t=3 months= 90 days (
considering that in 1 month there are 30 days)
Replacing:
velocity = 122.22 
<u><em>The average velocity that these birds travel is 122.22 miles per day to the south.</em></u>
Hello!
Everything you've done so far seems to be correct. However, you need to get rid of the sin. To do this, use s
.
This is known as the inverse of sin, which is where you go from a fraction to the actual angle itself.
When you run 
through a calculator, you get about 11.537 degrees, or θ = 11.537.
To verify this, all you need to do is run sin (11.537), and the calculator returns 0.2, which is what we're looking for.
Hope this helps!
Answer: The answer is C, Yes, her star will have appeared to move very slightly to the west.
Explanation: If your looking at a certain star, it usually goes to the west at night time very slightly, it doesn't go to the east because the Earth's axis tilts mostly on the west side. So it makes it true.
The two main things are speed and velocity. you have to factor in a bunch of smaller things too, but those don't really have much of an effect. And mass inertia is the resistance of any physical object to any change in its state of motion. The velocity of an object will determine the inertia that the object has. Good luck on your assignment and have a great day! :D
