m/s^2 is (m/s)/s ie rate of change of velocity per sec. ie accelerationplanation:
Answer:
New Madrid earthquakes are centered in a plate interior, meaning they were intraplate earthquakes.
Explanation:
The 1811-1812 new madrid earthquakes were different from most california earthquakes because the New Madrid earthquakes were centered in a North American plate interior caused by stress within the plates.
The New Madrid earthquakes often referred to as the "Tecumseh's Comet" was the biggest earthquake in America history.
Answer:
w = 73 N
Explanation:
Since the box is held by the ropes it means that the resulting tension is equal to the weight of the box
T_res = w
Now, the resulting tension is a combination of the tension of each rope.
Since we want to find the vertical component we must multiply by the cosine of 30 degrees the value of T
T_res = T*cos(30) + T*cos(30)
T_res = 2*(42 N)*(0.866)
T_res = 72.746 N
T_res = w = 72.746 N
A: makes work easier to do.
