Answer: The fluid would rise.

The cooler fluid then replaces the warm rising fluid and a current is set up (see illustration above). So, where gravity is a factor, such as here on earth, the natural fluid motion moves the heated, less dense fluid up and the cooler, more compact fluid down.
Hope that helps

An object of mass m moving at a speed of v1 possesses kinetic energy that is equal to KE1. When the object's speed is doubled, t

Vera_Pavlovna [14]

Answer:

KE₂ = 4KE₁

Explanation:

KE₁ = ½mv₁²

KE₂ = ½mv₂²

KE₂ = ½m(2v₁)²

KE₂ = 4(½mv₁²)

KE₂ = 4KE₁

The eye is actually a multiple-lens system, but we can approximate it with a single-lens system for most of our purposes. When t

hram777 [196]

Explanation:

Given that,

The optical power of the equivalent single lens is 45.4 diopters.

(a) The relationship between the focal length and the focal length is given by:

$f=\dfrac{1}{P}$

$f=\dfrac{1}{45.4}$

f = 0.022 m

or

f = 2.2 cm

(b) We need to find how far in front of the retina is this "equivalent lens" located. It is given by using lens formula as :

$\dfrac{1}{v}-\dfrac{1}{u}=\dfrac{1}{f}$

Here, u = infinity

$\dfrac{1}{v}=\dfrac{1}{2.2}$

v = 2.2 cm

So, at 2.2 cm in front of the retina is this "equivalent lens" located.

Hence, this is the required solution.

The concept of energy can be calculated in multiple ways. Which units are used for energy? Check all that apply. joules kilogram

MrMuchimi

Answer:

W = F * S = Newtons * Distance = Joules (definition)

Joules and KiloJoules are obviously methods of describing energy

F = M a = kg * m / s^2 definition of force

F * S = kg * m^2 / s^2 also describes work
