Answer: B. The south magnetic pole attracts the north pole of another magnet.
Explanation:
The correct statement below about the interaction between magnets, magnetic materials and charges is that the south magnetic pole attracts the north pole of another magnet.
We should note that a magnet typically consists of two poles which are the North Pole and the South pole. The opposite poles doesn't repel each other but attracts each other while same pole repels one another.
In this case, the North Pole will attract the South Pole while same magnetic piles repel e.g the North Pole will repel the North Pole.
Answer:
The water is 1310.75 meters deep.
Explanation:
The question gives us the speed of sound and the time the sonar signal takes to travel to the bottom of the water and back.
To find out the distance, we should first divide the time in half, so we only consider the time taken for the sound to reach the bottom of the water body.
This means:
Time = 1.75 / 2 = 0.875 seconds
The distance traveled in this time is:
Distance = Speed * Time
Distance = 1498 * 0.875
Distance = 1310.75 meters
Thus, the water is 1310.75 meters deep.
Answer:
"its varying position means that the Sun lights up different regions, creating the illusion that the Moon is changing shape over time. The best way of getting to understand the lunar phases is to regularly go out on a clear night when the Moon is in the sky and observe it."
4.22
Explanation:
The most acidic rainfall in New York State will have pH of 4.22 whereas the least acidic will be that of 4.40.
The pH scale expresses the acidity or alkalinity of aqueous solutions.
- The pH scale ranges from 1 to 4
- An acidic solution will have a pH value less than 7
We have given a range of values between 4.22 to 4.40
This implies that the pH values of rainfall in this region falls between these extremes.
The least value 4.22 is the most acidic
The value 4.4 is the the least acidic
The lower the pH value, the more acidic a solution is.
