I'm doing a presentation over real-world applications of physics and the group I am in wants to do "the physics of video games"
artcher [175]
Most modern games have a sense of real-world physics, but not exactly perfect. In a video game, the realistic movement or action greatly depends on the precision of coding. In real life, movement isn't done or programmed by a strand of code.

Your presentation sounds interesting, being a gamer myself, I would look forward to it. But the choice lies in your hands. If you do reconsider, be sure you have a backup plan. Good luck to you.

why do you think we have different seasons (fall, summer, winter, spring) in certain areas of the world?
Verizon [17]

Answer:

how the areas are at

Explanation:

The tilt of the Earth's AXIS is the most important reason why seasons occur... The area depends why there's  a certain differnt season on differnt areas , its because one area is closet to the sun which mostky they get summer full time (like a normal year), but  Alaska,it just winter , the reason why Alaska is just cold because its not close to the sun.

Both Josef Loschmidt and Amedeo Avogadro contributed to our understanding of basic molecular numbers, sizes, and reaction ratios
lbvjy [14]

The  Avogadro’s number is used to represent the number of elementary entities that exist in one mole of a compound.

<h3>What is the  Avogadro’s number?</h3>

The  Avogadro’s number is used to represent the number of elementary entities that exist in one mole of a compound. The numerical value of the  Avogadro’s number is obtained as 6.02 x 10^23 and consists of the atoms, molecules and ions in the compound.

The scientist Josef Loschmidt strengthened the  Avogadro’s number  by  obtaining the number of particles in one cubic centimeter of gas under standard conditions.

A cardinal (Richmondena cardinalis) of mass 3.70×10−2 kg and a baseball of mass 0.144 kg have the same kinetic energy. What is t
Radda [10]

Answer:

\frac{p_{c}}{p_{b}}\approx 0.507

Explanation:

Since the cardinal and ball have the same kinetic energy, it is possible to determine the ratio between speeds. (c for cardinal, b for baseball)

K_{c} = K_{b}

\frac{1}{2}\cdot m_{c}\cdot v_{c}^{2}= \frac{1}{2}\cdot m_{b}\cdot v_{b}^{2}

\frac{v_{c}}{v_{b}}=\sqrt{\frac{m_{b}}{m_{c}} }

The ratio is obtained by multiplying each side by \frac{m_{c}}{m_{b}}:

\frac{p_{c}}{p_{b}}=\frac{m_{c}}{m_{b}}\cdot \sqrt{\frac{m_{b}}{m_{c}} }

\frac{p_{c}}{p_{b}}= \sqrt{\frac{m_{c}}{m_{b}} }

The value of this ratio is:

\frac{p_{c}}{p_{b}}\approx 0.507
