Answer:

Explanation:

Since the apple is 641kg/m3 and water is 1000kg/m3 then the apple will float. Light materials float on top of the water similar to how oil is always on top of the water layer. Since the two are close so the apple will partially float

Answer:

$\Delta x = 3.65 \mu m$

Explanation:

As we know that the sixth order maximum will have path difference given as

$\Delta x = N\lambda$

here we know that

N = order of maximum

$\lambda = 609 nm$

now we have

$N = 6$

so we know that

$\Delta x = 6(609 nm)$

$\Delta x = 3.65 \mu m$

What is the relationship between the speed of an object and its kinetic energy?

VladimirAG [237]

Answer:

For the purposes of your question, we can think of speed and velocity as being the same thing. Therefore, the kinetic energy of an object is proportional to the square of its velocity (speed). In other words, If there is a twofold increase in speed, the kinetic energy will increase by a factor of four.
