Answer:don’t mind this I just needed to answer five questions and im not smart
Explanation:
A thin layer of till
that blankets the landscape after a glacier melts is called ground moraine.
Ground moraines<span> <span>are
till-covered areas with irregular topography and no ridges, often forming
gently rolling hills or plains. They are accumulated at the base of the ice as
lodgment till, but may also be deposited as the glacier retreats.</span></span>
Answer:
The mass of A and B together is 125kg
Explanation:
To solve this problem, we set up the equations expressing the net force acting on A and B (forces acting to the right are +, those acting to the left are -):

The net force acting on B is due to the acting pull force 100N less friction force caused by A. The net force on A is due to the friction force caused by the block B. Since we know both blocks accelerate at the same rate, the system can be solved easily:

Of course, alternatively, in this very simple case you could consider A+B a single object being pulled with 100N, and obtain the same results by diving the pull force by the acceleration.
