Answer 1

Answer: entropy measures : D. Messiness

Entropy often interpreted as the degree of disorder or randomness in the system thermal energy for conversion into mechanical work, so the best way to describe it is it measures 'messiness'

Explanation:

Which of the following statements about ice melting is true and why?A. Energy flows from the ice to its surroundings.
B. Water molecules move from their fixed position.
C. Water molecules lose energy.
D. The temperature of the ice increases as it melts.

Answers

The answer for this question is part B that is Water molecules move from their fixed position.

This is because when water is freeze it is in a solid condition that means the molecules are held together tightly and are are vibrating in their fixed positions.

As soon as the molecules gain energy they start to move around from their fixed positions and turn into a liquid.

In the process of doing so ice melts and becomes water.

option(D) is true
the ice molecules are taking in heat from its surroundings to melt and form water.This increases the temperature of ice as it melts.
option(c) can also be true because to form water,the intermolecular force between the molecules gets weak which allows them to move from their fixed point.

In what distance will a car traveling with 100 kN stop if a force of -200N is applied?

Answers

The descriptions of both the car's motion and of the proposed action are
defective, so the question is unanswerable.

-- The car's motion could be described in terms of its speed or its kinetic
energy, but "100 kN" is meaningless as a description of motion.

-- To describe a force as negative ("-200N") is meaningless as long as
neither a frame of reference nor a positive direction has been defined.

The length of some fish are modeled by a von Bertalanffy growth function. For Pacific halibut, this function has the form L(t) = 200(1 – 0.956e–0.18t ) where L(t) is the length (in centimeters) of a fish t years old.(a) Find the rate of change of the length as a function of time

Answers

Answer:

Rate of change of length as a function of time is given by $(dL(t))/(dt)=34.416e^(-0.18t)$

Explanation:

The length as function of time is given by $L(t)=200(1-0.956e^(-0.18t))$

Differentiating with respect to time we get

$(dL(t))/(dt)=(d(200(1-0.956e^(-0.18t))))/(dt)\n\n(dL(t))/(dt)=200(d(1-0.956e^(-0.18t)))/(dt)\n\n=200* 0.18* 0.956e^(-0.18t)\n\n(dL(t))/(dt)=34.416e^(-0.18t)$

A swinging pendulum demonstrates what type of energy

Answers

The correct answer to the question is : Mechanical energy.

EXPLANATION:

Let us consider a pendulum which is raised to certain height. The energy possessed by the pendulum at this height is gravitational potential energy.

Let the pendulum is released. Now the potential energy of the pendulum is converted into kinetic energy. At the mean point, whole of its potential energy is converted into kinetic energy.

Due to inertia, the pendulum will overshoot its mean position and will move towards its extreme position. During its movement from mean point to extreme point, the kinetic energy is converted into potential energy. At extreme point, whole of its kinetic energy is converted into potential energy.

Hence, there is only energy conversion between kinetic energy and potential.

We know that sum total of kinetic energy and potential energy is called mechanical energy.

Hence, the correct answer is mechanical energy.

Potential and kinetic energy .

There are three kinds of levers. What makes them different from each other?

Answers

Every lever and every class has a fulcrum, load, and effort. It helps move a heavy load.

Class one is when the fulcrum is the main acting force to help carry this weight.

Class two is when the person needs to put more effort to carry a weight.

Class three is when load itself helps carry a weight.

It all depends where the load, effort, and fulcrum are located. If the fulcrum is in the middle, it would be the most supportive force. If the fulcrum was at an edge, the effort or load would be the main forces of carrying, depending on their location. Location is important.

They all work synergistically to carry different things. They all help carry, but the different classes seperate them by fulcrum, effort, and load. Also note that the fulcrum is a very important part of a lever, without it, carrying a big box would be very heavy in the absence of a handler.

FULCRUM is the most important part! Remember that!

1. Seesaw . Fulcrum Middle That balances it
2. Wheelbarrow . Fulcrum is the wheel. Input = handles Output = objects inside wheelbarrow
3. Baseball bat . Fulcrum is the hands. Input = Bottom section of the bat. Output = top section of the bat with more force.
