Answer:

Planck's radiation law, a mathematical relationship formulated in 1900 by German physicist Max Planck to explain the spectral-energy distribution of radiation emitted by a blackbody (a hypothetical body that completely absorbs all radiant energy falling upon it, reaches some equilibrium temperature, and then reemits

A constant force = 2.00 n + 3.00 n acts on a 5.00 kg object as it moves in a straight line from the position1 = 1.00 m + 1.00 m
nata0808 [166]

force acting on the object is given as

F = 2.00\hat i + 3.00 \hat j

initial and final positions are given as

r_i = 1.00 \hat i + 1.00\hat j

r_f = 4.00 \hat i - 1.00\hat j

now the displacement is given as

d = r_f - r_i

d = (4.00 - 1.00)\hat i + (-1.00 - 1.00)\hat j

d = 3 \hat i - 2\hat j

now the work done is given as

W = F.d

W = (2.00\hat i + 3.00\hat j).(3\hat i - 2\hat j)

W = 0

so there is no work done

mart [117]

According to the condensation theory, the most important factor for the formation of our planets was "the interstellar dust attracting heat away from the protosun".


Condensation is the procedure by which water particles noticeable all around bunch together and shape fluid water. This is regularly observed outwardly of cold glasses. This idea additionally identifies with the solar system.

The condensation theory of the solar system expresses that our solar system, and perhaps all other galaxies, were shaped from a cloud of residue and gas that consolidated into strong issue. Space experts trust that the littlest grains of residue in our cloud applied a draw on the gas about it, 'consolidating' into bigger and bigger bits of issue, similarly as a snowball moving downhill will become bigger and bigger. In the long run, the gravitational draw of these residue atoms was sufficiently solid that they started to pull in each other, developing into greater and greater clusters that had more grounded gravitational pulls. In the long run, these bunches of residue and gas from the cloud frame a star, and potentially planets, space rocks, and comets turning about the star.
