Another machine uses an input of 200 newtons to produce an output force of 80 newtons what is the mechanical advantage of this machine

Answers

Answer 1
Answer:

If the input machine produces an output of 80 Newtons, then the mechanical advantage is that it produces work. If the required output must be 80 Newtons, then the input force is desirable having 100 percent production of force even though it requires a large amount of input to produce 80 Newtons of force.

Can somebody please explain to me how the acceleration in simple hormonic motion is proportional to the displacement..

Answers

When you graph simple harmonic motion in an acceleration versus displacement graph, the graph at any point would be linear. The graph would also pass through the origin giving proportionality of acceleration to negative displacement. Definition of proportionality neglects the negative value of the displacement so therefore acceleration is proportional to displacement. The acceleration of the motion is always directed towards equilibrium and so at maximum displacement, there would be greatest negative acceleration and vise versa.At the origin, the displacement would be zero and acceleration would also be zero

As the particles in a soup reach the boiling point what do you expect to happen

Answers

As the particles in a soup reach the boiling point, the kinetic energy of the molecules will start increasing and ultimately bubbles will be created in the soup and it will slowly start to vaporize. Boiling point of a liquid is the temperature at which the vapor pressure of the liquid will become equal to the atmospheric pressure.

Which best describes how heat flows? A. Heat flows from a warmer object to a colder object. B. Heat flows in any direction. C. Heat flows from a colder object to a warmer object. D. All objects transfer to their heat to all other objects.

Answers

The statement which best describes how heat flows is that the heat generally flows from a warmer object to a colder object. Therefore, the correct option is A.

The mechanism of heat flow significantly describes the transfer of heat energy or enthalpy from one object to another. It is transferred through the process of conduction, convection, and radiation.

The object that is warmer in appearance may accumulate heat in enough amounts. This leads to an increase in its temperature and energy, While the mechanism of heat transfer generally initiates this warmer object to a colder object by conduction.
