Explanation:
Physical characteristics would be used to distinguish the components of a mixture, including such scale, form, colour, weight, magnetic fields or the potential to drop or floating. As material is moved into a filter and the solid wastes are filtered out.
The first one is the second one and the second one is the first one
Answer:
Devon needs add 60 mL of 5% acid solution and 30 mL of 20% acid solution
Explanation:
It know acid and water concentration for every solution. 2 equation are proposed because there are two unknowns. V1= volume 5%acid and V2 =volume 20% acid
<em>Acid </em>V1(0.05)+V2(0.2)=90mL(0.1)
<em>Water </em>V1(0.95)+V2(0.8)=90mL(0.9)
Clearing V1 from acid equation having to: V1=180-4V2
Replacing V1 in water equation having to: (180-4V2)(095)+V2(0.8)=81
Clearing V2 = 30mL
Replacing in water equation V1(0.05)+30(0.2)=9 So, V1=60mL
I hope it helps
Answer:
Market economies are characterized by their free markets. Examples are the United States and the United Kingdom.
- That's pretty clear. What it means is that they trust in the free market and its operation to answer the questions of what to produce, how much to produce, and for whom.
Command economies are characterized by their control of markets. Examples are China and North Korea.
- They rely on the government, <em>not the free market itself, </em>to control what should be produced. This makes for a more strict system that can pay off in the long run, but can also run the risk of being heavy-handed.
I'd say that his comb has a static electricity charge. It can either be negative, or positive. Let's just say it's positive, and the water is negatively charged. This means that it will affect the water flow when the two charges meet. I hope this helps! ~Mia
