The rate the blood flows is affected by several factors including blood viscosity. If the blood
the thicker, how will it affect the flow of blood?

If you have thick blood, you're at greater risks for blood clots, both in your veins and arteries. Blood clots in your veins will impact blood flow to key areas of your body.

1. (1.2kw)x(15/60hours) = .3kwh --> a

2. (5kw)x(90/60hours)x(8cents/kwh) = $0.60 --> d

3. microwave --> 1200 watts = (1.2kw)x(6/60hours) = .12kwh

coffee-maker --> 900 watts = (.9kw)x(10/60hours) = .15kwh

therefore, it requires more energy for the coffee-maker to do the same amount of work.

so the answer is a.

coal is not sustainable because it will one day run out.
