Describe three physical changes that occur in nature?
Alex Ar [27]

Answer: Physical changes in nature could then be erosion in a mountain, the melting of snow, and a river freezing over from the cold. Since none of these changes affect the chemical composition of the mountain, the snow, or the river, they are physical changes.

A batter hits a foul ball. The 0.14-kg baseball that was approaching him at 40 m/s leaves the bat at 30 m/s in a direction perpe
swat32

Answer:

<em>7 kgm/s or 7 Ns</em>

Explanation:

Since the velocity are perpendicular to each other, the impulses will also be perpendicular.

From newton's second law of motion,

Impulse = mass×velocity

I = mv............. Equation 1

For the horizontal,

I₁ = mv₁......... Equation 2

Given: m = 0.14 kg, v₁ = 40 m/s

Substitute into equation 2

I₁ = 40(0.14)

I₁ = 5.6 kgm/s

Also for the vertical,

I₂ = mv₂.............. Equation 3

Given: m= 0.14 kg, v₂ = 30 m/s

Substitute into equation 3

I₂ = 0.14(30)

I₂ = 4.2 kgm/s

Using Pythagoras to get the resultant impulse

I = √(I₁²+I₂²)................ Equation 4

Substitute the value of I₁ and I₂ into equation 4

I = √(5.6²+4.2²)

I = √(31.36+17.64)

I = √49

<em>I = 7 kgm/s or 7 Ns</em>

An atom that has only one electron in its valence electron shell is ______ chemically reactive?
umka2103 [35]

The valence electrons are the electrons in the outermost electron shell of an atom.

Explanation:

The number of electrons in an atom's outermost valence shell governs its bondingbehaviour.

That is why elements whose atoms have the same number of valence electrons are grouped together in the Periodic Table.

Generally, elements in Groups 1, 2, and 13 to 17 tend to react to form a closed shell, corresponding to the electron configuration <span><span>s2</span><span>p6</span></span>.

This tendency is called the octet rule, because the bonded atoms have eight valence electrons.
