Answer:
The planet NEPTUNE was mathematically predicted before it was directly observed.
Answer:
Acids
Explanation:
Acids are ionic compounds that produce positive hydrogen ions when dissolved in water. Acids taste sour. They conduct electricity when dissolved in water. They also react with metals to produce hydrogen gas.
Answer:
I would say C because in number one, the tests were never repeated
Explanation:
do you mean
this question??
Experiment 1: A group of students tested to see if the acidity of water affected pea plant growth. The students followed a logical method and performed their experiment once, using control and experimental groups. Their results supported their hypothesis.
Experiment 2: A group of students tested to see if bacteria growth in water was affected by acidity. The students used control and experimental groups. They repeated their experiment several times and found the results were the same.
Which experiment most likely has greater reliability?
A. Number 1 because it follows a logical method
B. Number 2 because the experiment was repeated
C. Number 2 because the experiment was repeated and the results were always the same
D. Number 1 because it has control groups
The formulas that will be used are:
Situation one:
The moon will be experiencing gravitational force in the form of centripetal force, so we equate the two formulas.
Gravitational force = GMm /r²
Centripetal force = mv²/r
Equating,
GMm/r² = mv²/r
v² = GM/r
The first scenario will use the formula v² = GM/r
Situation 2:
The second situation will use the simple distance over time formula for velocity, where the distance will be the circumference and the time will be in seconds.
v = 2rπ/t
