what is the most likely reason that a hypothesis would be useful even if experiments show that is false

Answers

Answer 1
Answer:

Answer:

An observation is made. To understand why the phenomenon is occurring, a hypothesis is built up which can be tested by a scientific method. The result of the experiment can be true or false.

If the result false, it implies that the dependent and independent variables are not related and a new experiment must be designed or a modification is required in the experiment.

Thus, even if the result is false, the hypothesis would be useful because conclusions can be drawn from it and next course of action can be defined.

Answer 2
Answer: You are able to test your hypothesis if you do your experiment again.

A girl that has a mass of 30 kg is hanging from a bar motionless. Determine the following forces. If no force exists, enter 0. (use 10m/s2 for gravity) Weight Newtons
Applied force Newtons
Frictional Force Newtons
Normal Force Newtons
Tension Force
Net Force Newtons

Answers

Final answer:

The weight of the girl is 300 N. The applied force, frictional force, and normal force are all zero. The tension force in the bar is 300 N, and the net force is zero.

Explanation:

The weight of the girl can be calculated using the formula:

Weight = mass × gravity

where mass = 30 kg and gravity = 10 m/s2. Therefore, Weight = 30 kg × 10 m/s2 = 300 N.

Since the girl is motionless, the net force acting on her is zero. In this case, the tension force in the bar equals the weight of the girl, which is 300 N. The other forces (applied force, frictional force, and normal force) are also zero since the girl is not moving.

Therefore, the forces are:

  • Weight: 300 N
  • Applied force: 0 N
  • Frictional force: 0 N
  • Normal force: 0 N
  • Tension force: 300 N
  • Net force: 0 N

#SPJ1

As the speed of a fluid increases, ____.a. the pressure decreases
c. the force decreases
b. the pressure increases
d. the volume decreases

Answers

The correct answer for the question that is being presented above is this one: "a. the pressure decreases." As the speed of a fluid increases, the pressure decreases." The relationship of the speed and the pressure is inversely proportional. As the pressure increases, the speed decreases.

I think the answer is A.

Can a simple machine’s efficiency ever be greater than 100%?
Explain your answer.

Answers

100% efficiency is not possible, so any greater than 100% is also not possible. There is always some energy waste, normally through heat, sound, or light
Personally, I believe not. 100% is the total, and therefore, it cannot possibly be above 100% percent, as this wouldn't then mean that the machine is efficiently beyond its means

The earth's four main spheres continuously interact to support life and balance Earth's materials. When plants absorb carbon dioxide for photosynthesis, it is an example of _____ and _____ sphere interaction.biosphere, lithosphere; biosphere, atmosphere; hydrosphere, lithosphere; or cryosphere, lithosphere biosphere, lithosphere biosphere, atmosphere hydrosphere, lithosphere cryosphere, lithosphere

Answers

The correct answer for the question that is being presented above is this one: "biosphere, atmosphere." The earth's four main spheres continuously interact to support life and balance Earth's materials. When plants absorb carbon dioxide for photosynthesis, it is an example of biosphere and atmosphere sphere interaction.

Its "biosphere and atmosphere" because photosynthesis comes from the plants and the atmosphere then consumes the carbon.

A skier has an acceleration of −2.5 m/s2. How long does it take her to come to a complete stop from a speed of 18 m/s?

Answers

the answer to your question is 7.2

Answer:

7.2 seconds

Explanation:

The formula is a = v/t, or acceleration = the change in velocity over the change in time.

In this case, you do simple algebra to rearrange the formula to solve for time: t = v/a, time = velocity/acceleration.

time = 18 m/s / 2.5 m/s^2 = 7.2s
