The answer depends on the gradient of WHAT!
what do you mean by gradient of a scalar field? what do you mean by gradient of a scalar field?
concentration gradient
proton gradient
A concentration variation (gradient) in the direction from the head of an animal to its tail.
Rent or lease
land rent is an unearned income
The remuneration for land is Rent
I'd like to see a sample of farm land rent agreement.
A shallow gradient is a low slope of land. It usually has contour lines that are decent way apart from one another.
the payment for the right to use land
No rent land is defined as land which cannot be rented to others. This may be part of the original sales agreement or other legal limitations.
rent
the gradient and how much friction there was. The gradient means how steep the land the river is on so if it is very steep them the velocity will be higher.
Demand is the sole active determinant of land rent because the supply is fixed.
