The first law of thermodynamics requires that the energy input to a system must equal the energy output from a system plus the accumulation of energy in a system. If no energy is accumulating then the energy input is the heat in and the energy output is the work and heat out.

Can we have physical quantities which have magnitude and direction but are not vectors if yes how?

yes we can have. for eg electric current, pressure etc though these quantities have both magnitude and direction their directions are not necessary to define them and vectors are those quantities which has magnitude and requires direction to be defined " quantities having both magnitude and direction is a vector" is not a corrrect definition ofa vector


What crop need large quantities of water?

Rice is a crop that requires large quantities of water for cultivation. The field needs to be flooded during certain stages of growth to facilitate the production of rice. Other water-intensive crops include sugarcane and cotton.


Which thermoplastic fabrication process requires the least tooling?

3D printing typically requires minimal tooling as it involves building up a part layer by layer using a digital model, making it a cost-effective option for producing small quantities or custom parts.


Which law of thermodynamics is the reason that you need a constant input of energy to drive biological systems?

The Second Law of Thermodynamics states that a system with no energy input and no losses will tend towards a zero energy state. This is essentially the entropy of any energy exchange. Thus, you require a constant input of energy to maintain any system.


What is the difference between active transport and pass transport?

Pass transports require no energy and active requires energy. Osmosis is when it travels through water.

What is the difference between ecodynamic and thermodynamic?

There is very little overlap - if any - between thermodynamics and ecodynamics. Ecodynamics is a part of applied economics. It covers knowledge on monetary value, the usage of money and the money flow. It deals with labor, and capital. Ecodynamics has significant elements of sociology and psychology because it requires taking into account how people think and behave and what they value. Thermodynamics is a branch of physics concerned with heat and temperature and their relation to energy and work. Thermodynamics, especially statistical thermodynamics, is based on the idea of randomness and probabilities with no intelligent intervention. One way you could look at it is that Ecodynamics is how people behave with their resources while Thermodynamics is how resources behave in the absence of people.

How does the 2nd law of thermodynamics make evolution impossible?

The second law does NOT make evolution impossible. It just requires that as evolution takes place that there be an increase in entropy of the universe as a whole.

What is the difference between vector and scalar quantities?

Vector quantity is a quantity characterized by magnitude and direction.Whereas,Scalar quantity is a quantity that does not depend on direction.

Oxygen is the difference! Cellular respiration requires oxygen, while cellular fermentation does not.


Is Rubber good for you to eat?

Rubber contains nothing that the human body requires, so no - it is not good. In small quantities it will probably do no harm, but it shouldn't be eaten.
