Image result for Is work done when you carry a book across the room at a constant velocity

Work is not done when you carry an object forward. You may have learnt that carrying an object and moving horizontally at a constant velocity has no work done. The truth is, there is a slight amount of work done due to overcoming air resistance in the horizontal direction.

"No" according to the work energy theorem about work is done when there is a change in final and initial velocity. But if I use Work = Force x displacement, even though the velocity is constant there is still some displacement done by the (constant) force acting on it.

What is the similarity between trenches and subduction zones?
guapka [62]
I'll give you an example.

If two tectonic plates clide, more or less in a head-on collision, they form a convergent plate boundary.
Usually, one of the converging plates will move beneath the other, which is known as
subduction.
Deep trenches are often formed where tectonic plates are being subducted, and earthquakes are common.

olga nikolaevna [1]

Answer:

Lateral inhibition.

Explanation:

Lateral inhibition may be defined as the ability of an excited neuron to reduce or decrease the activity of ts side by or neighbor's neuron. The sensory [perception is increased during lateral inhibition.

The stronger response is detected at the surface edge rather than on the cell's middle surface. The excited neurons move in the lateral direction and decreases the activity of the middle or neighbor neurons.

Thus, the answer is lateral inhibition.
