Different temperatures must be true about two objects if heat is flowing between them
Answer: Option A
Explanation:
On bringing two objects with temperature differences, heat flows from a higher temperature to a lower temperature until there is thermal equilibrium according to the second law of thermodynamics.
Just like if we connect two tanks through a pipe with different water capacities. The water flows from the tank of higher water to a lower water level until both the tanks have the same water level.
The bigger the difference of temperature between two object, the higher the rate of heat flow from the hotter object to the cooler one. Two object, having same temperature doesn’t undergo a heat flow process.
The objects must be different temperatures. the exact temperatures don't matter

A) delta. B) plains. C) plateau. D) low lands.
The flat area surrounding the mouth of the mississippi river is known as Delta, or the Delta Basin of the Mississippi river, and the entire area was formed over the curse of 5,000 years by the deposition when the sediments are being put into this delta.
Answer:
F= 25/2 = 12.5N
Explanation:
When you use a compound pulley the force required depends on the mechanical advantage of the compound pulley. This is known as rate of loss of distance or the ratio of the force to the load.
M.A = Effort distance /Load distance. OR M.A = Load/Effort

Answer:
a.
ionic compounds
Explanation:
Answer:
Heterogeneous
Explanation:
A chemical substance is composed of one type of atom or molecule. A mixture is composed of different types of atoms or molecules that are not chemically bonded. A heterogeneous mixture is a mixture of two or more chemical substances where the various components can be visually distinguished.
