B. They required fewer people to operate.
Answer:
Asthenosphere, the zone of Earth's mantle resting underneath the lithosphere and supposed to be much hotter and more fluid than the lithosphere. The asthenosphere lengthens from about 100 km (60 miles) to about 700 km (450 miles) below Earth's surface.
Explanation:
I'm sorry, I just saw this. I hope I'm not too late.
GPE = mass * gravity * height
height = GPE/(mass * gravity)
height = 50/(1/2 * 9.8)
height = 10.2041 Meters
The first question's answer is :
If, F=ma
Then, 15N= 2.1kg (a)
15/2.1=a
7.14=a
Therefore, acceleration = 7.14m/s^2
sorry I am not sure about the second question :-(
