the answer is b. it's commercially reprocessed
Convection currents are responsible for powering the movement of tectonic plates.
Further Explanation:
As the dogs collectively full the sled on the wet snow surface, the sled will experience a net force due to all the dogs acting on it.
Part (a):
The net force applied by the 8 dogs on the sled is:
The net mass of the dog and the sled combined is:
The net acceleration of the dogs and the sled combined is:
Substitute the values of net force and mass in above expression.
Thus, the acceleration of the dogs as they pull the sled on the snow is .
Part (b):
Since the sled is moving with an acceleration of , the net force experienced by the sled due to the pull of the dogs is:
Substitute the values in above expression:
Thus, the force experienced by the sled due to the dogs is .

A bottle opener is a type of lever that reduces the input force required by reducing the distance over which the force is applied.
B.
A bottle opener is a type of lever that enables the same work to be done over a shorter distance with less force.
C.
A bottle opener is a lever in which a smaller input force acts over a larger distance so that a larger output force can act over a smaller distance.
D.
A bottle opener is a type of lever that magnifies the output force required.
How is this different from a distance-time graph?
Answer:
its devavtion is different from the distance changes process
Explanation:
A speed-time graph and a distance-time graph represent different aspects of motion. A horizontal line on the former indicates a constant speed (zero acceleration), while a straight, upward-diagonal line on the latter shows constant speed. A flat horizontal line on a distance-time graph shows no movement.
A speed-time graph and a distance-time graph each depict different aspects of motion. A horizontal line on a speed-time graph does indeed indicate constant speed or zero acceleration; the object is moving at a constant speed. However, a distance-time graph shows how the position of the object changes over time.
Let's take an example. If a car is traveling at a constant speed, on a speed-time graph, this would be represented by a horizontal line. The height of the line above the time axis represents the constant speed.
On a distance-time graph, a car moving at constant speed will be represented by a straight line with a positive slope. This is because the position of the car is continuously changing (it's covering distance), and at a constant rate. The slope of the distance-time graph gives us the speed of the car.
So, while a flat horizontal line in a speed-time graph indicates constant speed, a flat horizontal line in a distance-time graph would indicate no change in position, i.e., the object is not moving at all.
