My guess would be "B) they were produced by volcanoes" because hawaii has a bunch of volcanoes and volcanoes can produce extra land. While the other answers wouldn't make sense. Definitely B.
Answer:
it's an indicator that a chemical reaction occurred.
Answer : The specific heat capacity of lead is, 
Explanation :
In this problem we assumed that heat given by the hot body is equal to the heat taken by the cold body.
where,
= specific heat of lead = ?
= specific heat of water = 
= mass of lead = 100.0 g
= mass of water = 150.0 g
= final temperature = 
= initial temperature of lead = 
= initial temperature of water = 
Now put all the given values in the above formula, we get
Therefore, the specific heat capacity of lead is,
Answer:
continuously changing
Explanation:
The velocity of a person on a merry-go-round can best be described as continuously changing. This is because the initial velocity before the ride starts would be 0. Once the ride begins, it keeps going faster and faster until it reaches a certain speed. During this time the velocity is increasing. Then it remains constant for a certain period of time and when the ride is over the velocity and speed begins to decrease until ultimately reaching a speed of 0. Therefore, it is continuously changing throughout the duration of the ride.
The correct answer is C. Having a sour taste is not a property of a base instead it is a property of acids. The taste of a base is bitter. The other choices given are properties of a base. It feels slippery, changes the litmus paper to blue and produces OH- ions in aqueous form.
