Which is the largest and the main artery of the circulatory system
Pulmonary The main artery of the human circulatory system is called the aorta. It comes directly off of the heart, carrying oxygenated blood to other arteries that carry it to… the body's cells. About the thickness of your thumb, it is also the largest artery.

how did Bourne believe that an object could be made to rise or sink at will?
Explanation:
When an object is placed inside water, an upward force is exerted by water called as buoyant force.
An object will float or sink, this completely depends on the density of object. Also, if the magnitude of gravitational force is more as compared to the buoyant force the object will sink otherwise float.
If the density of substance is more than water, it will sink and if the density of substance is less than water it will float.
Help me please
True or false
1) an atom has no mass
2) an electron is the largest part of an atom
3) all atoms have the same mass
4) all protons have the same mass
5) all oxygen atoms have the same mass
6) an oxygen atom has the same atomic number as a hydrogen atom
7) to find the atom mass of an atom, we add the protons an electrons
8) the atomic number of an atom is the number of neutrons it has
9) atoms of the same kind that have different numbers of neutrons are called isotopes
10) atomic number = atomic mass

On a hot summer day several swimmers decide to jump into a river. They step off the bridge and strike the water at 1.5s later. Ignore air resistance. What is the height of the bridge?
I did it but I don’t know if it’s right
When on a hot summer day several swimmers decide to jump into a river. They step off the bridge and strike the water 1.5 seconds later. Ignore air resistance, then the height of the bridge would be 11.03 meters.
What are the three equations of motion?There are three equations of motion given by Newton,
v = u + at
S = ut + 1/2×a×t²
v² - u² = 2×a×s
As given in the problem, when on a hot summer day several swimmers decide to jump into a river. They step off the bridge and strike the water 1.5 seconds later. Ignore air resistance,
By using the Second equation of motion,
S = ut + 1/2×a×t²
S = 0 + 0.5*9.81*1.5²
S = 11.03 meters
Thus, the height of the bridge would be 11.03 meters.

why did dalton devise his own element symbols
Final answer:
John Dalton created his own element symbols to visually represent the atoms and their combinations as part of his atomic theory. These symbols were crucial for the systematization of chemistry and preceded other symbol systems such as those of G. N. Lewis, which illustrate valence electrons and chemical bonding.
Explanation:
John Dalton, an English scientist, devised his own element symbols as part of his pioneering work in atomic theory. Dalton's atomic theory posited that elements are composed of indivisible atoms, that matter combines in fixed ratios, and that compounds always have consistent proportions. His element symbols, depicted in Dalton's book A New System of Chemical Philosophy, were an early attempt to represent these atoms and their combinations visually. These symbols laid the groundwork for the systematization of chemistry and were a precursor to later representations such as the Lewis dot symbols. Unlike Dalton's symbols, Lewis dot symbols focus on representing the valence electrons of atoms to predict chemical bonding and formation, as G. N. Lewis published in 1916.
Without Dalton's work, our understanding of the chemical composition of matter and the development of subsequent theories of chemical bonding, such as those proposed by G. N. Lewis, might have been significantly delayed. Dalton's dedication to empirical evidence and experimentation set his atomic theory apart from the philosophical ideas of ancient Greeks like Democritus and Leucippus, contributing greatly to the advancement of modern science and chemistry.
Is it possible for you to take a hike and have the distance you cover be equal to the magnitude of your displacement?
Distance can be equal to displacement ... if the motion is all in a straight line ... but distance can never be greater than displacement.
Yes, it is possible that the distance can be equal to the displacement. a further explanation is given below.
A intervals metric that is taken somewhere across a track could be determined as the Distance, and the measurement of just a specific duration or short timeframe could be considered as a Displacement.Whenever you walk down the road throughout the one manner, the distance, as well as the size of the whole movement, become equivalent or comparable.
Thus the above answer is right.

the answer is temperature
a plane travels 2.5 km at an angle of 35 degrees to the ground and then changes Direction and travels 5.2 km and an angle of 22 degrees to the ground what is the magnitude and direction of the Plains total displacement
We can solve for the resultant x and y components by using the sine and cosine functions.
resultant x = 2.5 cos 35 + 5.2 cos 22 = 6.87 km
resultant y = 2.5 sin 35 + 5.2 sin 22 = 3.38 km
The resultant displacement is calculated using hypotenuse equation:
displacement = sqrt (6.87^2 + 3.38^2)
displacement = 7.66 km
The resultant angle is:
θ = tan^-1 (3.38 / 6.87)
θ = 26.20°
Therefore the magnitude and direction is:
7.66 km, 26.20° to the ground
