Answer:
It's A
Explanation:
As the waves progress through the medium, the particles they are made of move perpendicular to the direction in which the waves move. The particles do not move with the wave. So waves transmit energy but not matter as they progress through a medium.
There are very scarce food resources for the other animals and for the deers themselves which can cause massive death if all of the food is eaten
Answer:
The runners are 0.159 mi to the west of the flagpole.
Explanation:
Let´s place the origin of the frame of reference at the point where the flagpole is located.
The initial position of runner A is 3.91 mi and his velocity is -6.04 mi/h
The initial position of runner B is -2.95 mi and his velocity is 5.00 mi/h
When both runners meet, their position is the same. The equation of the position of each runner is:
x = x0 + v · t
Where
x = position at time t
x0 = initial position
v = velocity
t = time
Then, at the meeting point:
x runner A = x runner B
3.91 mi - 6.04 mi/h · t = -2.95 mi + 5.00m/h · t
Solving for t:
3.91 mi + 2.95 mi = 5.00m/h · t + 6.04 mi/h · t
6.86 mi = 11.04 mi/h · t
t = 0.621 h
Now, we use this time to find the meeting point. We can use the equation of any runner. Let´s use the position of runner A:
x = 3.91 mi - 6.04 mi/h · 0.621 h = 0.159 mi
Since the position is positive, the runners met 0.159 mi to the west of the flagpole.
Answer:
left side
Explanation:
It's smaller in length but still has a pretty close slope to the right side.
