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

Answer:
5 N
Explanation:
The work done by a force on an object is (assuming that the direction of the force is parallel to the displacement of the object):
where
F is the magnitude of the force
d is the displacement of the object
In this problem, we know that:
W = 35 J is the work done
d = 7 m is the displacement of the object
Therefore, we can re-arrange the equation to calculate the force applied:
