. Which of the following is not an ultimate goal of science?A. Understand patterns
B. Give explanations for natural events
C. Make predictions
D. Produce unchanging, absolute answers

Answers

Answer 1
Answer: What is not the ultimate goal of science is to produce unchanging and absolute answers - D. Scientists would like to, however, understand patterns, give explanations for natural events, and even make predictions. And it isn't really the case that they would like to produce unchanging answers.

Heat in a substance is an example of _____ energy?

Answers

Heat in a substance is still an example of heator thermal energy. Heat or thermal energy is further defined as the amount ofavailable molecules of kinetic energy transferred in a specific amount of time.Heat is nothing if it is not transferred from one object to another. There aremany uses of heat energy. When we are cooking using our stoves, there is heatenergy. When we pour hot water onto our cup of coffee, there is heat energy.

A 139 kg physics professor has fallen into the Grand Canyon. Luckily, he managed to grab a branch and is now hanging 89 m below the rim. A student (majoring in linguistics and physics) decides to perform a rescue/experiment using a nearby horse. After lowering a rope to her fallen hero and attaching the other end to the horse, the student measures how long it takes for the horse to pull the fallen physicist to the rim of the Grand Canyon. The acceleration of gravity is 9.8 m/s 2 . If the horse’s output power is truly 1 horsepower (746 W), and no energy is lost to friction, how long should the process take? Answer in units of s.

Answers


In order to lift the fat (306 lb) physics professor 89 meters up to
the rim, he'll need more potential energy, equal to

      (mass) x (gravity) x (height) = (139 x 9.8 x 89) = 121,236 joules .

If the faithful horse delivers 1 constant horsepower = 746 watts,
AND if the cute-as-a-button student has instantly figured out a
way to keep the rope sliding around the edge without any friction,
then the soonest Prof. Tubby can arrive at the rim is

    (121,236 joules) / (746 joules/sec) = 162.5 seconds . 

Nowhere in this tense drama has the student needed her linguistics
skill yet, but I'll bet it comes in handy as she attempts gamely to
comprehend all of the various pleadings, prayers, and expletives
uttered by her heavy hero from the time he falls over the rim until
he's again lifted to it.

Which of the following states that absolute zero cannot be reached?A. the second law of thermodynamics
B. the first law of thermodynamics
C. the second and third laws of thermodynamics
D. the third law of thermodynamics

Answers

The second and third laws of thermodynamics states that absolute zero cannot be reached. The correct option among all the options that are given in the question is the third option or option "C". Both the laws actually deal with the relations that exist between heat and other forms of energy. I hope the answer helps you.

Answer:

D. the third law of thermodynamics

Explanation:

As per third law of thermodynamics we know that entropy of a perfect crystal comes to zero when the temperature of the crystal reaches to absolute zero.

So as per the theory of entropy we know that entropy of a system cannot be zero as it will reach zero then system will not exist.

So here we can say that

As per third law it is not possible to achieve zero kelvin or absolute zero temperature because at that temperature the entropy will become zero and then the system will not exist in that case.

So here we can say the correct answer will be

D. the third law of thermodynamics

A change in the thermal energy of an object is related to the object s specific heat, temperature change, and mass. TRUE or FALSE.

Answers

The statement: "A change in the thermal energy of an object is related to the object s specific heat, temperature change, and mass." is True. An object's total heat capacity is called heat capacity, and it is affected by the amount of thermal energy required to raise the temperature by 1 degree C.
