Answer:
H₂0_{(s)} + heat → H₂O(l)
Explanation:
An ENDOTHERMIC reaction is a chemical reaction in which heat is absorbed by the reactants. As such the product is usually cooler than the products. In the equation above (the answer), heat is on the reactant side of the equation thus indicating that heat is absorbed by the reactants.
On the other hand, in the first equation heat is on the product side of the equation which is consistent with an Exothermic reaction.

This is Kinematics and the equations in your book.
A speed time graph would plot the speed of something against the teime it was at a speed.
If it were changing it speed constantly, that would be a straight line if acclerating. Total distrance would be the area under the graph.
To generate clean energy the mayor my build the fooling type of energy plants:
wind farms
solar power plants
wave power plants
Explanation:
At the seaside there are winds all over the year and that can be transformed in electrical energy by a wind turbine. The mayor can build a on-shore wind farm (reduced consts) and may also build off-shore wind farms (but these have an increased cost).
The second option is to build solar power plants. It will be cost effective if the people in the town will install solar panels on the building roofs. In this way you decrease the costs with the transportation of electrical energy.
The third option is to install wave power plants which harvest energy from the sea waves. It is a rather new technology, in comparison with the other two, but the initial consts can be amortized over time.
All three options will provide clean energy.
Right now nuclear plants have a very expensive initial costs and they may not be afforded by small towns.

The overriding problem with both theories of muscle growth, hypertrophy and hyperplasia, is that __________.
A.
neither can be accepted as correct because muscles growth is difficult to study in humans
B.
neither one is theoretically possible
C.
neither has been studied by reputable scientists
D.
neither has been accepted by member of the fitness community
Please select the best answer from the choices provided.
A
B
C
D
Answer:
The smallest and largest areas could be 6400 m and 7500 m, respectively.
Explanation:
The area of a rectangle is given by:
Where:
l: is the length = 100 m
w: is the width
We can calculate the smallest area with the lower value of the width.
And the largest area is:
Therefore, the smallest and largest areas could be 6400 m and 7500 m, respectively.
I hope it helps you!
