Which parts of the body act as levers? a. muscles b. joints c. bones d. veins

Physics
2 answers:
nignag [31]4 years ago

The answer is <u>"c. bones".</u>


Muscles and bones act together to frame levers. A lever is an unbending pole (for the most part a length of bone) that turns about a rotate (more often than not a joint). Switches can be utilized with the goal that a little power can move a substantially greater power. This is called mechanical advantage.



Levers can likewise be utilized to amplify development, for instance, when kicking a ball, little withdrawals of leg muscles deliver a significantly bigger development toward the end of the leg.

Bromium has two naturally occurring isotopes: 79br, with an atomic weight of 78.918 amu, and 81br, with an atomic weight of 80.9
saul85 [17]

The two different isotopes have weights :

w1 = 78.918 amu

w2 = 80.916 amu

average weight w3 = 79.903 amu

The mixing of two components can be modeled as

let the fraction of w1 be 'x'

hence w1. x + w2.(1-x)  = w3

now this is a linear equation in 'x'. Substituting the values we get

x = 0.507

hence the percentage of Br79 = 50.7% and the percentage of BR81 = 49.3%

How do fossils provide evidence that evolution has taken place
zzz [600]
<span>Fossils provide solid evidence that organisms from the past are not the same as those found today; they show a progression of evolution. Scientists calculate the age of fossils and categorize them to determine when the organisms lived relative to each other. Hope this helps</span>

If a nucleus was as big as a nonpareil, an atom would be ____
Mamont248 [21]

Answer:

small marble  

Explanation:

A nonpareil are confectionery tiny ball items that are made up of starch and sugar. It is very small of the size of sugar crystal or sand grains. They were the miniature version of the comfits. They are generally opaque white but bow available in all colors.

In the context, if the nucleus is compared to the size of a nonpareil then its atom would be of the size of small size marble. An atom is bigger in size than that of nucleus as the nucleus is located inside the atoms.

Rocks are elastic too! Explain how elasticity and Harry Reid's elastic rebound theory lead to a better understanding of earthqua
ANEK [815]
After the great 1906 San Francisco earthquake, geolophysicistHarry Fielding Reid examined the displacement of the ground surface along the San Andreas Fault. He concluded that the quake must have been the result of the elastic reboundof the strain energy in the rocks on either side of the fault.
strain energy is 0. 5x force x (compression) X (compression)
There is a lot of force and a bit of compression when rocks squash up against other rocks causing earthquakes

Dimensional formula of frequency with explation
____ [38]

Frequency:

Frequency is defined as number of events occurring per second.

  • Mathematically written as

                                             f=\frac{no. of events}{time}

  • The dimensions f are

                                      [f]=\frac{1}{[T]}

as

                                      [T]=[S]

so,

                                     [f]=[S^{-1}]
