An article in ieee international symposium on electromagnetic compatibility quantified the absorption of electromagnetic energy and the resulting thermal effect from cellular phones. the experimental results were obtained from in vivo experiments conducted on rats. the sample mean and sample standard deviation arterial blood pressure values (mmhg) for the control group (8 rats) during the experiment are x1 90,s1 5 and for the test group (9 rats) are x2 = 1 15,$2 = 10. is there evidence to support the claim that the test group has higher mean blood pressure? (a) state the null and alternative hypothesis, the test statistic, and the critical region. (b) do the data support the claim that the mean blood pressure from the test group is at least 15 mmhg higher than the control group? state the null and alternative hypothesis the test statistic, and the critical region. (5 points) for a bacteria population with an initial biomass concentration of 235 mg/l and a ke 0.55 days , calculate the time necessary to reduce the population to 0.005 mg/l assuming that the food supplies have been exhausted. start your solution with the general growth rate expression: フ dx

quantum mechanics or quantum physics is physics of very small objects (particles) and physical entities.

quantum physics has some parallels to our macro world and some pretty unique ideas which theoretically and mathematically proven to be true even though we will never be able to access them because of our size.

there are many types of particles: subatomic, elementary etc.

subatomic means they are smaller than atom, elementary means they are at the very basis of everything.

subatomic particles are for eg. protons, neutrons but not electrons.

elementary particles are categorised into 3 groups by what they do.

these 3 groups are quarks, leptons and bosons.

light for example is a particle more precisely a photon a part of leptons.

proton (subatomic particle) is made out of 2 up quarks and 1 down quark each of these has a fractional charge like . (i crazy)

most famous scientist who contributed to this physics are:

the topic itself us understand a lot and will probably be vastly used in the future (quantum computers, understanding the big bang,

we also must not forget quantum effects like:

and there is more. but probably too much for this answer to be consistent due to my average understanding of this topic.

hope this you understand quantum mechanics a little more. i'm not an expert in the topic (so don't be like wth if you are an expert) but i'm very interested in it.

anyways quantum physics is a very hard topic (harder than physics (perhaps)) therefore searching for every information there is about it and learning it is unfortunately impossible (you can only specialise into 1 - 3 things or more (perhaps

have fun and i wish you luck!

i need the answer to this too but idk it ; -;

i think the answer would be b
