Answer: The three main rock types are igneous, metamorphic and sedimentary.
The three processes that change one rock to another are crystallization, metamorphism, and erosion and sedimentation.
Any rock can transform into any other rock by passing through one or more of these processes. This creates the rock cycle.
Explanation:
Answer:
The solution is given below.
Explanation:
Speed = Distance(m)/Time(sec.)
Distance traveled = 150 m
Time taken = 3.5 seconds
Speed of car = 150/3.5 = 42.86 m/s
So the car traveled at a speed of 42.86 m/s.
Answer:
True
Explanation:
Depends of the size and comparison
440 hertz = 440/seconds
1/440 seconds = period of the sound wave.
so Answer is 2.2727272* 10^-3 second or 1/440 seconds
Answer:
change the concentration of one reactant while keeping the other concentrations constant
Explanation:
For a given reaction;
A + B --> C + D
The reaction rate may be given as;
Rate = k[A][B]
In the above rate equation, the orders of both reactants ( A and B) is 1 . Reaction order is basically how the concentration of the reactant affect the rate of the equation.
The correct option is;
change the concentration of one reactant while keeping the other concentrations constant.
That way, one can monitor how a particular reactant affect the rate of the reaction.
