Cold freshwater<span> is </span>denser<span> than </span>warm seawater<span>, because of the salinity and temperature variations. Cold water would have less salt since the solubility of the salt is lower as compared to warm water. Hope this answers the question. Have a nice day.</span>

Answer:

  • There is always the difference of energy that each atoms has inside its electronic configuration and this factor of the molecules or atoms provides the basic structure or arrangement of atoms inside the given space.As, the difference inn temperature,T or the total energy possessed by these number of molecules are the deciding factor inside the given space or region.
  • While, the atoms or molecules of the cold freshwater are said to be low on calcium ions and that they posses the energy in more compact form inside the inter molecular bonds, leaving the medium with less energy  in order to raise its temperature,T. So, the cold water has less temperature as compared to the warm seawater which posses more unsystematic-ally arranged atoms in the whole configuration of the medium.
  • And that is the reason that cold water are more dense or has more arranged or we can say that compact form of molecular arrangements inside there body, as compared to the warm water having less or proper arrangements of the molecules or atoms.

False.

As temperature increases the more the electrons begin to vibrate more, as it decreases they vibrate less.

Calculate the orbital speed (in m/s) of a satellite that circles the Earth with a time period of 12.00 hours. The mass of the Ea
Hoochie [10]

Answer:

v = 3869 m/s

Explanation:

As we know that the orbital speed of the satellite is given as

v = \sqrt{\frac{GM}{r}}

also we know that

time period of the revolution is given as

T = \frac{2\pi r}{v}

now from above equation we know that

T = \frac{2\pi (\frac{GM}{v^2})}{v}

T = \frac{2\pi GM}{v^3}

so we will have

v = (\frac{2\pi GM}{T})^{1/3}

now plug in all data in this equation

v = (\frac{2\pi (6.67 \times 10^{-11})(5.97 \times 10^{24})}{12 \times 3600})^{1/3}

v = 3869 m/s

A horizontal rectangular surface has dimensions 2.80 cm by 3.20 cm and is in a uniform magnetic field that is directed at an ang
koban [17]

Answer:

magnitude of the magnetic field 0.692 T

Explanation:

given data

rectangular dimensions = 2.80 cm by 3.20 cm

angle of 30.0°

produce a flux Ф = 3.10 × 10^{-4}  Wb

solution

we take here rectangular side a and b as a = 2.80 cm and b = 3.20 cm

and here angle between magnitude field and area will be ∅ = 90 - 30

∅ = 60°

and flux  is express as

flux Ф = \int \vec{B}.d\vec{A}   .................1

and Ф = BA cos∅    ............2

so B = \frac{\phi }{Acos\theta }    

and we know

A = ab

so

B = \frac{\phi }{abcos\theta }    ..............3

put here value

B =  \frac{3.10\times 10^{-4} }{2.80 \times 10^{-2}\times 3.20 \times 10^{-2}\times cos60}  

solve we get

B = 0.692 T
