While visiting the beach, you enjoy the warm ocean water, but the sand burns your feet. That night you walk along the beach and

notice that the sand is colder than the ocean water. Why?
Group of answer choices

It takes a long time for sand to heat up, but it cools down very quickly. Water takes a short time to heat up and cool down.

Since sand can heat up quickly, it will also cool off quickly. But water takes a long time to heat up and cool down.

Water is naturally colder than sand.

A moving van travels 10km North, then 4 km east, drops off some furniture and then drives 8 km south. (a) Sketch the path of the
Juli2301 [7.4K]

Answer:

4.47 km

Explanation:

If we draw the path of the van then we get a shape with two exposed points A and D. If we draw a line from point D perpendicular to BA we get point E. This gives us a right angled triangle ADE.

From Pythagoras theorem

AD² = AE² + ED²

AD=\sqrt{AE^2+ED^2}\\\Rightarrow AD=\sqrt{2^2+4^2}\\\Rightarrow AD=\sqrt{20}\\\Rightarrow AD=4.47\ km

Hence, the van is 4.47 km from its initial point

A calorimeter has a heat capacity of 1265 J/oC. A reaction causes the temperature of the calorimeter to change from 22.34oC to 2
Ray Of Light [21]
<h2>Heat released in this process is 3516.7 J</h2>

Explanation:

A calorimeter has a heat capacity of 1265 J/°C

Heat capacity of calorimeter = 1265 J/°C

A reaction causes the temperature of the calorimeter to change from 22.34°C to 25.12°C

Change in temperature = 25.12 - 22.34 = 2.78°C

Heat released = Heat capacity of calorimeter x Change in temperature

Heat released = 1265 x 2.78 = 3516.7 J

Heat released in this process is 3516.7 J

In a white dwarf, electrons are packed in so tightly that they physically cannot get any closer to one another. This provides an
Natalka [10]

Answer:

The white dwarf will start to get darker.

Explanation:

The white dwarf will keep is spherical shape, since electron degeneracy pressure (outward direction) will counteract the force of gravity due to its own mass (inward direction) which lead to hydrostatic equilibrium.

A nuclear reaction occurs when light elements combine into heavier elements (that is know as nucleosynthesis). Exist different ways in which that can happen, but the most common is the Proton-Proton chain. In that fusion reaction, two atoms of Hydrogen combine to form helium, while the fusion takes place, photons are created.

Photons are the elementary particles that constitute light and taking into account that in white dwarfs the production of photons has ceased because there are no nuclear fusions, then, it is clear that the white dwarf will start to get darker as it cools since is emitting into space the photons produced in the past.
