<span>Heat in a substance is still an example of heat or thermal energy. Heat or thermal energy is further defined as the amount of available molecules of kinetic energy transferred in a specific amount of time. Heat is nothing if it is not transferred from one object to another. There are many uses of heat energy. When we are cooking using our stoves, there is heat energy. When we pour hot water onto our cup of coffee, there is heat energy.</span>

Can an object in motion ever change directions?
choli [55]

Answer:

Forces affect how objects move. They may cause motion; they may also slow, stop, or change the direction of motion of an object that is already moving. Since force cause changes in the speed or direction of an object, we can say that forces cause changes in velocity.

Answer:

Our answer is D

Explanation:

Efficiency = Work Done/Heat Input = 80/80 = 1

The coordinates of a particle in the metric​ xy-plane are differentiable functions of time t with StartFraction dx Over dt EndFr
Brut [27]

Answer:

\dfrac{dD}{dt}=-7.076\ m/s

Explanation:

It is given that,

The coordinates of a particle in the metric​ xy-plane are differentiable functions of time t are given by :

\dfrac{dx}{dt}=-6\ m/s

\dfrac{dy}{dt}=-4\ m/s

Let D is the distance from the origin. It is given by :

D^2=x^2+y^2

Differentiate above equation wrt t as:

2D\dfrac{dD}{dt}=2x\dfrac{dx}{dt}+2y\dfrac{dy}{dt}

D\dfrac{dD}{dt}=x\dfrac{dx}{dt}+y\dfrac{dy}{dt}.............(1)

The points are given as, (12,5). Calculating D from these points as :

D=\sqrt{12^2+5^2} =13\ m

Put all values in equation (1) as :

13\times \dfrac{dD}{dt}=12\times (-6)+5\times (-4)

\dfrac{dD}{dt}=-7.076\ m/s

So, the particle is moving away from the origin at the rate of 7.076 m/s. Hence, this is the required solution.
