Archimedes discovered relationships between density and floating. He discovered that the mass of an object will have density to the volume being displaced.

Slav-nsk [51]4 years ago

Answer: The correct answer is density and floating.

Explanation:

Buoyant forces is forces exerted by the fluid on the object immersed in it.

Archimedes discovered the relationship between the density and floating.

Archimedes principle states as: the buoyant force on the object is equal to weight of the fluid is displaces.

F_B=w_f

F_B = Buoyant force on the object

w_f = Weight of fluid displaced by the object

Density is the measure of mass present in per unit volume of the object.

  • If the density of the object is greater than the density of the fluid in which it is immersed then it will get sink. This because more the mass more weight of the fluid it will displace
  • If the density of the object is less than the density of the fluid in which it is immersed then it will float. This is because lesser the mass lesser the weight of fluid it will displace.

Hence, the correct answer is density and floating.

Did you think about this over Christmas? I did (-: Before Christmas a 65kg student consumes 2500 Cal each day and stays at the s
Gnesinka [82]

Answer:

a)  Em = 332.8 J , b) # jump = 13, c)   It is reasonable since there are not too many jumps , d) lower the calories consumed

Explanation:

a) Let's use energy conservation

Initial. On the floor

             Em₀ = K = ½ m v²

Final. The highest point

             Emf = U = m g h

Energy is conserved

             Em₀ = Emf

             ½ m v² = m g h

             h = ½ v² / g

            h = ½ 3.2² /9.8

            h = 0.52 m

b) When he was at home he maintained his weight with 2500 cal / day. In his parents' house he consumes 3500 cal / day, the excess of calories is

            Q = 3500 -2500 = 1000cal / day

Let's reduce this value to the SI system

             Q = 1000 cal (4,184 J / 1 cal) = 4186 J / day

Now the energy in each jump is

               Em = K = ½ m v²

               Em = ½ 65 3.2²

               Em = 332.8 J

They indicate that the body can only use 25% of this energy

              Em effec = 0.25 332.8 J

              Em effec = 83.2 J

This is the energy that burns the body

Let's use a Proportion Rule (rule of three), if a jump spends 83.2J how much jump it needs to spend 1046 J

              # jump = 1046 J (1 jump / 83.2 J)

              # jump = 12.6 jumps / day

              # jump = 13  

c) It is reasonable since there are not too many jumps

d) That some days consume more vegetables to lower the calories consumed

What are the independent and dependant variables in Plate Tectonics Lab Report?
tresset_1 [31]

Answer:

I don't know the exact answer but I think this is it.

The independent variable is the variable the experimenter changes or controls and is assumed to have a direct effect on the dependent variable. The dependent variable is the variable being tested and measured in an experiment, and is 'dependent' on the independent variable.

Worldwide, the total number of land animals killed for food every hour is ______.
NISA [10]

Answer:

8 million animals

Explanation:

This is because all over the world, animals are consumed as food and they serve as source of protein.

Animals are used to make different delicacies depending on the choice of the consumer and it is the major source of protein. Every hour, about 8 millions are killed and are sold to consumers and other parts of it can be use for other things. Examples of animals consumed are goat, sheep, cow, chicken e t.c.
