Answer:

Within each element square, information on the element's symbol, atomic number, atomic mass, electronegativity, electron configuration, and valence numbers can be found. At the bottom of the periodic table is a two row block of elements that contain the lanthanoids and actinides.

Answer:

Using the data in the table scientists, students, and others that are familiar with the periodic table can extract information concerning individual elements. For instance, a scientist can use carbon's atomic mass to determine how many carbon atoms there are in a 1 kilogram block of carbon.

Why does Alpha Centauri appear to be yellow-white?
viktelen [127]
Actually, the real reason it appears yellow-white is because of the temperature of the star. the stars that are hotter tend to be more blue and the stars that aren’t as hot tend to be more red/orange/yellow.

IP A spark plug in a car has electrodes separated by a gap of 6.5×10−2 in . To create a spark and ignite the air-fuel mixture in
emmainna [20.7K]

Answer:

a.) V=5283.2 \ V

b.) V=4064\ V

Explanation:

<u>Electric Field and Potential Difference</u>

There are several conditions that must be met for a spark to be created into an air gap. Once the physical conditions are fixed, a minimum electric field is necessary for the spark to be initiated. Let s be the separation between the electrodes and V their potential difference. The electric field is

a.)

\displaystyle E=\frac{V}{s}

Solving for V

V=E.s

The separation is

s= 5.5\cdot 10^{-2}\ in=0.001651 \ m

Thus the potential difference is

V=3.2\cdot 10^{6}\ V/m\times 0.001651 \ m

V=5283.2 \ V

b.) If the separation was greater, the applied voltage needs to be greater if the electric field has to be constant. One possible measure to keep electrodes as close as possible is to build them as sharp edges. It gives the spark an easier path to travel to.

If the separation is 0.05 inches =0.00127 m

V=3.2\cdot 10^{6}\ V/m\times 0.00127 \ m

V=4064\ V

A ball is thrown downward; and its speed is v just before it strikes the ground. After the collision with the earth, it heads up
d1i1m1o1n [39]

For this case it is necessary to consider the assessments made between collisions of 'immovable' objects. In this case the earth is the immovable object or at least, it is approached by its mass. Considering the case of an inflatable ball of mass m that travels at a speed v towards the ground, it hits the floor and bounces with speed -v (Negative). The earth does not move, however, the momentum of the ball has changed by 2mv since the speed went from positive to negative. Applying the conservation of the momentum we know that the change of the momentum on the fly would be given under the function

p = m\Delta V

Considering the direction of the velocities this expression can be rewritten as

p = m (v-(-v))

p = 2mv

Therefore the correct answer would be

C. Only the momentum of the ball is changed by the collision
