Answer:
A mixture is a combination of two or more pure substances that are not chemically combined. Mixtures are held together by physical forces and therefore can be separated physically.
air pollution would cause trees to die and animals to die . It would coaus most harm by killing everything on land and in the sea beacuse the animals that die might wash away in the ocean killing other animals slowly but surely. and it doesnt help there is soil erosion sooner rather that later it will turn into nothing.
Explanation:
Answer:
Correct answer is A, they regulated the ticking of the clock...
Explanation:
The atomic clock uses a more fundamental vibration, and it uses it as part of a self-regulating system. A crystal of quartz has two properties that help it keep time.
The atoms serve the same purpose as did pendulums or quartz crystals in earlier clocks. They have no “hands” to turn or liquid crystal displays for number read-outs. They simply produce electrical pulses that serve as a standard for calibrating other less accurate clocks.
To answer this question, you need to convert the 16.1 megabyte into second first. If the rate is 93kb/second, then the calculation would be:
16.1 mb x (1000kb/mb) / (93kb/second)= 173.12 second.
Then 16.1 mb music will last for 173.12 second. After that you can convert it into minutes: 173.12/ (60second/min)= 2.885 minutes.
<h3><u>Answer;</u></h3>
≈ 18,116,438 N/m² or 18,116,438 Pascals
<h3><u>Explanation;</u></h3>
- Pressure is the force exerted on a unit area.
- Thus pressure is given by; Force/ Area. Therefore, pressure is measured in N/m² or pascals.
In this case, the force is 52,900 Newtons
The area = 2,920 cm²
But; 1 m² = 1000000 cm², thus;
Area = 2,920 cm²/ 1000000 cm²
= 0.00292 m²
Pressure = 52,900 Newtons/ 0.00292 m²
= 18,116,438.356 N/m²
≈ 18,116,438 N/m² or 18,116,438 Pascals
