What energy transformations are going on within the skateboarder’s body during this process?
balandron [24]

Answer:

When they slide down, they lose this potential energy, which turns into kinetic energy and thermal energy. Thermal Energy - This energy is related to the temperature of a body or a system. When friction is involved in a system, part of the kinetic energy is transformed into thermal energy.

Answer:

1.Earth

2.tidally

3.spin

4.Kuiper

5.A solar nebula forms when the gas and dust are pulled together in a spinning disk. Particles began to clump together due to gravity, and larger chunks of material exert more gravity on nearby dust and gas. These chunks of material grew faster and formed planets or moons. Denser elements such as iron settled closer to the center of the solar nebula.

In the currently accepted atomic model, an electron orbits the nucleus in a<br> clear, defined path.
Alex777 [14]

FALSE

In the currently accepted atomic model, an electron orbits around the nucleus is NOT in a clear, defined path.

Explanation:

According to modern atomic models, like the Bohr theory, it is difficult to know the exact location and path of an electron around the nucleus. This is partly because the mere act of observing the electrons changes its position. This is because the electrons have negligible mass and therefore ‘hitting’ them with any form of radiation for ‘illumination’ changes its position, behavior, and properties. In addition, the movement of electrons is very rapid such that by the time one observes the instantaneous location of an electron, if it was possible, it will have changed its position.

Therefore modern theories, such as VSPER, model atoms based on properties of where an electron will highly likely be found. This is how the shells and subshells of electrons (s, p, d, f) are modeled.

pentagon [3]

Answer:

Null hypothesis: male and female spiders organized in mating pairs don't differ significantly in respect to body length

Alternative hypothesis: male and female spiders organized in mating pairs exhibit significant differences in respect to body length

The application of one statistical test in order to obtain one p-value (probability value) may provide useful evidence to support the alternative hypothesis (or reject it).  

The inference procedure uses the information collected from the sample in order to obtain one conclusion.  Frequentism is a type of inference procedure that can be used to test a hypothetical test case, which is here represented by male and female spiders organized in mating pairs.
