Answer: if you build a wall that when the water hits it it seperates the sand from the water and spits the water onto the ocean side of the wall and spit the sand on the beach side but also build a bridge to that people can get to the water if wanted
Explanation:
if you put a wall it would block you from getting to the water or vice versa.
a) Copper is at a higher temperature, so the flow of heat will take place from copper to iron. Heat is a form of energy, which always flows from higher temperature to lower temperature.
b) To determine the actual final temperature, the heat capacity of the calorimeter must be known. A calorimeter constant refers to a constant, which quantifies the heat capacity of a calorimeter. It may be determined by using a known amount of heat to the calorimeter and measuring the corresponding change in temperature of the calorimeter.
Answer:
c.mass and distance
Explanation:
gravitation=mass/distance ²
Hello!
<span>A chemical that will ignite spontaneously in air at a temperature of 130 degree fahrenheit (54.4 degree celsius) or below is identified by the term pyrophoric.
Pyrophoric substances are those that ignite spontaneously when in contact with air at 130 °F or below. Some substances that are pyrophoric include Iron Sulfur (FeS) or some metals like finely powdered Uranium. To handle pyrophoric substances, it is required to work in an inert atmosphere (i.e. an atmosphere without oxygen).
Have a nice day!</span>

. We approximate that this is the change in potential energy for the reactants going to the products.

The above is for an endothermic reaction.
A certain feature of combustion reactions suggests that you should draw the diagram DIFFERENTLY from what you see above. How should the energy of the products compare with that of the reactants for combustion reactions?
