Answer:
frictional
Explanation:
B
C
all did the same amount of work
Answer: all did the same amount of work
Explanation:
The work done by each mountain climber to climb the mountain is equal to how much gravitational potential energy they gained in the climb, and this is given by
where m is the mass of the climber, g is the gravitational acceleration, and is the gap in altitude.
Since the three climbers have same weight, they also have same mass, so the term "m" in the formula is the same. Also, they started from the same altitude and arrive at the same altitude, so the gap is the same for all of them. Therefore, they gain the same gravitational potential energy, and so they did the same amount of work. So, the work does not depend on the path taken.
B. the rate of evaporation of a fluid
C. how much energy it takes to warm a fluid
D. the density of a fluid
E. a fluid's resistance to flowing
Answer:
E. a fluid's resistance to flowing
Explanation:
Viscosity, also known as "thickness" is a rheological property that describes a fluid's resistance to flowing, fluids of low viscosity, like water, flow more easily while high viscosity fluids, like mud, are harder to move through. It is an important property because it determines the energy required to make a certain fluid flow.
Answer: law
Explanation: A law is a rule that is used to explain the observation of a body. It could be represented in form of verbal or mathematically.
when the answer is considered as always true under every condition tested, it becomes a law that would be used to know other variables.
1. Domain, kingdom, phylum, class, order, family, genus, species, and subspecies.
2. If a variety of the species with a certain gene is vulnerable to a specific disease, predator, or environmental development, other members of the species with variants of the gene may be better equipped to handle the problem, and the species won't die out, just a portion of the disadvantaged.
