Answer:
E=mc2
Explanation:
It explains that in their interiors, atoms fuse together, creating energy.
The basketball player must be going at 3.57 m/s<em> </em>when she leaves the ground.
<u>Given the following data:</u>
We know that acceleration due to gravity (a) for an object or body is equal to 9.8 meter per seconds square.
To find how fast (velocity) the basketball player must be going when she leaves the ground, we would use the third equation of motion;
<u>Where:</u>
- S is the distance covered.
Substituting the given parameters into the formula, we have;
<em>Final velocity, V </em><em>= </em><em>3.57 m/s</em>
Therefore, the basketball player must be going at 3.57 m/s<em> </em>when she leaves the ground.

<u>Answer:</u> The correct answer is two electrons are shared between each hydrogen atom and the carbon atom bonded to it, and four electrons are shared between the carbon atoms.
<u>Explanation:</u>
Ethylene is a compound given by the chemical formula .
The bond present between hydrogen and carbon atoms or carbon and carbon atoms are covalent bonds. A covalent bond is formed by the sharing of electrons between the atoms combining.
A double bond is present between carbon and carbon atoms. So 2 pairs of electrons are shared which means in total of 4 electrons are shared.
Bond present between hydrogen and carbon atoms are single bonds. So, a pair of electrons is shared which means that in total of 2 electrons are shared.
Hence, the correct answer is two electrons are shared between each hydrogen atom and the carbon atom bonded to it, and four electrons are shared between the carbon atoms.
Explanation: The moon's gravity, combined with the waltz of Earth and the moon around their center of mass, forces the oceans into an oval shape, with two simultaneous high tides. ... If the moon were half its mass, then the ocean tides would have been correspondingly smaller and imparted less energy to it.
