Answer:
The correct option is;
Absolute zero
Explanation:
A Bose-Einstein condensate is known as the fifth state of matter which is made of a collection of ultra cooled atoms (at almost absolute zero degrees -273.15 °C) such that the there is very slight free energy within the atoms which results in almost no relative motion between the atoms. The atoms then combine forming clumps such that phenomena usually observed at the microscopic level such as wavefunction interference become observable at the microscopic level.
Answer:
Elastic potential energy into kinetic energy
Explanation:
Initially the energy is stored inside the spring, which is compressed. This form of energy is called elastic potential energy, and its formula is
where k is the spring constant, which gives the 'strength' of the spring, while x is the compression/stretching of the spring with respect to its equilibrium position.
When the spring unwinds, it returns to its equilibrium position, so x becomes zero and the potential energy converts into another form of energy, which is related to the motion of the car (in fact, the car starts moving). This form of energy is called kinetic energy, and its formula is
where m is the mass of the car and v is its speed.
Answer:
I believe its Gas to Solid :)
Explanation:
Answer: convection
Explanation:
There are three ways in which the heat (thermal energy) transfer occurs:
<u>1. By Conduction</u>, when the transmission is by the direct contact.
<u>2. By Convection</u>, heat transfer in fluids (like water or the air, for example).
<u>3. By Radiation</u>, by the electromagnetic waves (they can travel through any medium and in vacumm)
In this especific case, we will talk about convection, which occurs when the hottest parts of a fluid ascend to the coldest zones, generating a continuous circulation of the fluid (better known as convective current) transmitting heat to the cold zones by decreasing the density caused by the increase in temperature.
This is what happens in Earth, when the convective heat transfer occurs, through the movement of groups of molecules that make up the medium (water and air in this situation) changing with temperature and creating the weather .
Answer:
A. Force of friction
Explanation:
Find the diagram attached
From the diagram we can see that the force B is acting up on the body along the plane. This force is the force that prevents the body from sliding down the plane. Originally, the body on the line will tend to slide down the incline even without application of a force hence the reason of an opposing force that must act in the opposite direction is counter this motion to make the body be in a state of equilibrium. Hence the required force is force of friction since it is am opposing force acting in the direction opposite to the moving force acting on the body.
