What is the simulation theory?

1 answer:

The simulation hypothesis<span> contends that reality is in fact a simulation (most likely a </span>computer simulation<span>), of which we, the simulants, are totally unaware. Some versions rely on the development of simulated reality, a fictional technology.</span>

A bob of mass m = 0.250 kg is suspended from a fixed point with a massless string of length L = 22.0 cm. You will investigate th

To solve the problem, it is necessary to use the concepts of gravitational force, centripetal force and trigonometric components that can be extrapolated from the statement.

By definition we know that the Force of Gravity is given by

$F_g=mg$

Where,

m= Mass

g = Gravitational Acceleration

The centripetal force is given by,

$F_c = \frac{mv^2}{R}$

Where,

m = Mass

v = Velocity

R = Radius

For the case described in the problem, the Force of gravity the net component would be given by sin?, While for the centripetal force the net component is in the horizontal direction, therefore it corresponds to the $cos\theta$

Then,

$F_g = mg sin\theta$

$F_c = \frac{mv^2}{r}cos\theta$

From the radius we have its length but not the net height, which would be given by

$r = L sin\theta$

So equating the equations we have to

$F_g = F_c$

$mg sin\theta=\frac{mv^2}{r}cos\theta$

$mg sin\theta=\frac{mv^2}{Lsin\theta}cos\theta$

Re-arrange to find v,

$v = \sqrt{\frac{gLsin^2\theta}{cos\theta}}$

Replacing with our values

$v = \sqrt{\frac{(9.8)(22*10^{-2})(sin^2 24)}{cos24}}$

$v = 0.624$

Therefore the tangential velocity of the mass is 0.624m/s

compare the numbers of each subatomic particle found in both diagrams and then list what makes hydrogen diffrent from hellium

Cloud [144]

The helium atom is found to contain more particles than the hydrogen atom.

<h3>What is a subparticle?</h3>

An atom is composed of particles and these particles are electrons protons and neutrons. The collective name for these particles is the subatomic particles.

Now we know that the helium atom contains more sub atomic particles than the atom of hydrogen. This is because, the helium atom contains two neutrons and two protons as well as two electrons. On the other hand, the hydrogen atom contains one neutron and one proton as well as one electron.

Thus, the helium atom is found to contain more particles than the hydrogen atom.

Answer:

Number of absent affects the grade

Explanation:

the dependent variable is the grade and the independent variable is the number of absent, since the grade depends of the number of absents.

Two trains of length 90m and120m<br>

Alenkasestr [34]

Answer:Train A is 90 m long and running at 72 km/h.

Train B is 120 m long and running at 36 km/h.

When the trains are running in opposite directions, their relative speed gets added: 72+36 = 108 km/h.

The total length of A and B = 90+120 = 210 m

So the time taken to cross each other = 210 m*60*60/108*1000m

= 7 seconds

Explain why people who use the drug in the following scenario might have potential health risks.

Feliz [49]

Answer:

People who may take this drug may have potential health risk because there is poor quality in that drug just because a drug doesn't exceed the weight limit doesn't mean quality doesn't matter quality matters just as much as the weight limit does
