Answer:
A
Explanation: this is because 1. the particles were HELD together. after the particles are released, they move with their own forces in opposite direction as such, they move in their respective directions.
2. when we consider the electrostatic force of attraction, oppositely charged particles would attract when the depletion boundaries are exceeded as such they tend to move in the direction of the force with the greatest magnitude
Answer: subduction and sea floor spreading
Explanation:
He knew that the continents today were once joined together by fossil records of plants and animals that were found to be on continents far removed from each other. He knew this also by corresponding land forms that matches up as well. What he couldn’t prove is how the land masses would have moved so far away from each other. Subduction and sea floor spreading move the tectonic plates that the continents sit on. That’s what he was missing.
Answer:
27.22dm³
Explanation:
Given parameters:
number of moles = 1 mole
temperature = 50°C, in K gives 50+273 =323K
Pressure = 98.6kpa in atm, gives 0.973atm
Unknown:
Volume of the gas = ?
Solution:
Since the unknown is the volume of gas, applying the ideal gas law will be appropriate in solving this problem.
The ideal gas law is mathematically expressed as;
Pv = nRT
where P is the pressure of the gas
V is the volume
n is the number of moles
R is the gas constant
T is the temperature
Input the parameters and solve for V;
0.973 x V = 1 x 0.082 x 323
V = 27.22dm³
Answer:
science needs both ideas the hypothesis and facts the quantitative results to move forward
Explanation:
the two primary features of a scientific hypothesis are falsifiability and testability which are reflected in an If…then statement summarizing the idea and in the ability to be supported or refuted through observation and experimentation
Answer:
The correct answer is B it"s a proven fact.
Explanation:
Any scientific theory is based upon many experiments ans observations.The experiment and observations are repeated many times to provide a scientific logic about that theory.
A scientific theory is accepted only when that theory is logically proved by various experiment ,observations,statistical analysis etc.
