Answer:

It's weight would decrease over time.

Explanation:

The cold coke is going to stabilise in the room temperature. This causes the coke to heat up to room temperature. When the coke heats up, some molecules acquire enough kinetic energy that the evaporate. The evaporation of the molecules causes a decrease in weight.

Hope it helped!

“Force of impact”is:

Bumek [7]

In mechanics, an impact is a highforce or shock applied over a short time period when two or more bodies collide. Such a force or acceleration usually has a greater effect than a lower force applied over a proportionally longer period. ... Resilient materials will have betterimpact resistance.

What are forces that two objects apply on each other

liq [111]

Answer: Whenever two objects are touching, they usually exert forces on each other. The force of gravity, on the other hand, is an example of a force that exists between objects without them having to be in contact. Objects with mass exert forces on each other via the force of gravity.

During an early phase of the planet's existence, earth's atmosphere was similar in composition to the atmospheres of mars and ve

KengaRu [80]

The answer is carbon dioxide. This primordial earths’ atmosphere was composed by gasses from degassing of the earth's interior after its formation. It is after the beginning of life that oxygen levels began to rise and levels of carbon dioxide began to reduce in the atmosphere (as a result of photosynthesis).

An air-gap, parallel plate capacitor with area A and gap width d is connected to a battery that maintains the plates at potentia

sergejj [24]

Answer:

The new potential energy decreases by the factor of 2 to the old potential energy.

Explanation:

Capacitance of a parallel plate capacitor is given by the relation :

C = (ε₀A)/d

Here ε₀ is vacuum permittivity, A is area of the capacitor plate and d is the distance between them.

Potential energy of the capacitor, U = $\frac{1}{2}CV^{2}$

Here V is the potential difference between the plates.

According to the problem, the distance between the plates get double but area remains same. So,

d₁ = 2d

Here d₁ is new distance between the plates.

Hence, new capacitance is :

C₁ = (ε₀A)/d₁ = (ε₀A)/2d = C/2

The capacitor have same potential difference that is V. Hence, the new potential energy is :

U₁ = $\frac{1}{2}C_{1} V^{2}$ = $\frac{1}{2}\frac{C}{2} V^{2}$

U₁ = U/2

$\frac{U_{1} }{U} = \frac{1}{2}$
