Answer:
It will double.
Explanation:
Newton's Law of Gravity states that , where G is the gravitational constant, <em>r</em> is the distance between the objects' centers, and and are the objects' masses. We just have simple math here: by doubling , we double the entire fraction. By doubling the entire fraction, we double the gravitational pull. Therefore, <em>Newton's Law of Gravity states that if the mass of one object doubles, the gravitational pull on a second object will </em><em>double</em><em>.</em>
I hope this helps you understand it! Have a great day, 'kay?
Height increase h = R*(1 - cosΘ) = 1.2*(1-cos3.5°) = .00224 m.
<span>½Mbl*Vbl² = Mbl*g*h → </span>
<span>Vbl = √(2gh) = .2095 m/s </span>
<span>This is the initial velocity of the block. From momentum considerations, </span>
<span>Mbt*Vbt = Mbl*Vbl → </span>
<span>Vbt = (Mbl/Mbt)*Vbl = (5/.002)*.2095 = 523.8 m/s
this is what i think the answer is im not for sure though... hope it helps...</span>
The answer is:
when Bohr's original model stated that electrons were tiny little objects circling the nucleus along fixed orbits, however, this is no longer valid as we now know that rather "circling" the nucleus at confined orbits, electrons can seem to be everywhere at once
.
-So, The correct answer for this question would be QUANTIZATION OF ENERGY. The aspect of Bohr's original model of electron structure that is still included in the currently accepted theory of electron structure is the quantization of energy.
-Bohr suggested circular orbits of electrons around the nucleus of a hydrogen atom, but researches have shown that motion of the electron is not in a single plane., but it takes place in three-dimensional space. Actually, the atomic model is not flat

Answer:
Explanation:
According to Kepler's second law: a line segment joining an object and the Sun sweeps out equal areas during equal intervals of time. This law is equivalent to the constancy of the angular momentum, that is to say:
Here, is the comet's mass, is its distance from the Sun, is its speed and the angle between and
The aphelion and the perihelion are the only two points in the orbit where the radius and velocity are perpendicular. Therefore, at these 2 points, the angular momentum module can be calculated as a simple product:

Answer: sum of the electric field energy density and magnetic field energy density.
Explanation:
The total energy stored in an electromagnetic wave is equal to the sum of energy stored in the electric and magnetic fields. In that case, the energy stored per unit volume, or energy density of the electromagnetic wave, is the sum of the electric field energy density and magnetic field energy density.
