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.

What evidence did wegener have to support his theory of plate tectonics?
PSYCHO15rus [73]

Answer:

Wegener first thought of this idea by noticing that the different large landmasses of the Earth almost fit together like a jigsaw puzzle. The continental shelf of the Americas fits closely to Africa and Europe, and other continents showed the same trend. Wegner also analyzed both sides of the Atlantic Ocean for rock type, geological structures and fossils and noticed that there was a significant similarity between matching sides of the continents, especially in fossil plants.

AlekseyPX

Answer:

P_{out} = 0.100 W = 100 mW

Explanation:

The attached image shows the system expressed in the question.

We can define an expression for the system.

The equivalent equation for the system would be

G_{total} = G_{1} + G_{2} + G_{3}\\G_{total} = -16dB+20dB-10 dB = -6 dB

so, the input signal could be expressed in dB terms

P_{in} [dB] = 10 log_{10}(P_{in}) \\P_{in} [dB] = 10 log_{10}(0.4)\\P_{in} [dB] = -3.97 dB (1)

so the output signal could be expressed as.

P_{out} = P_{in} + G_{1} + G_{2} + G_{3}\\P_{out} = -3.97 dB - 6dB = -9.97 dB

The gain should be expressed in dB terms and power in dBm terms so

P_{out} = -9.97 + 30 = 20.03 dBm

using the (1) equation to find it in terms of Watts

P_{out} = 0.100 W = 100 mW

Q1) After applying a force of 1000 N an object of mass 2000 kg will achieve what<br>acceleration?​
wlad13 [49]

Answer:

F=mass x acceleration

1000= 2000 x a

a=1000/2000

a=1/2 m/sec^2
