A car started from a rest and accelerated at 9.54 m/s2 for 6.5 seconds. How much distance was covered by the car?

ElenaW [278]

Explanation:

S =ut + 1/2at^2

S = 0×6.5 + (1/2 × 9.54) × 6.5^2

S =0 + 4.77 ×42.25

S=201.5m

If you were to separate all of the electrons and protons in 1.00 g (0.001 kg) of matter, you’d have about 96,000 C of positive c

Kryger [21]

Answer:

The attractive force between them is $1.296 \times 10^{18}$ N

Explanation:

Given:

Charge $q = 96000$ C

Distance between two charges $r = 8$ m

According to the coulomb's law,

$F = \frac{kq^{2} }{r^{2} }$

Where $k = 9 \times 10^{9}$ = force constant.

$F = \frac{9 \times 10^{9} \times (96000)^{2} }{8^{2} }$

$F = 1.296 \times 10^{18}$ N

Therefore, the attractive force between them is $1.296 \times 10^{18}$ N

6. In baseball, a fastball takes about 1/2 second to reach the plate. Assuming that such a pitch is thrown horizontally, compare

klio [65]

Answer:

The ball falls 0.3 m in the first 1/4 seconds, and it falls 0.92 m in the second 1/4 second

Explanation:

Horizontal Launch

When an object is thrown horizontally with a speed v from a height h, it describes a curved path ruled exclusively by gravity until it eventually hits the ground.

To calculate the vertical distance (y) traveled by the object in terms of the time (t) we use:

$\displaystyle y=\frac{g.t^2}{2}$

The fastball is thrown horizontally. The distance the ball falls in t=1/4 seconds = 0.25 seconds, is:

$\displaystyle y_1=\frac{9.8*0.25^2}{2}$

$\displaystyle y_1=0.30625\ m$

The distance the ball falls in t=1/2 seconds = 0.5 seconds is:

$\displaystyle y_2=\frac{9.8*0.5^2}{2}$

$\displaystyle y_2=1.225\ m$

The distance it falls in the second 1/4 second is:

$y_2-y_1=1.225\ m-0.30625\ m$

$y_2-y_1=0.91875\ m$

The ball falls 0.3 m in the first 1/4 seconds, and it falls 0.92 m in the second 1/4 second

Which best explains the relationship between parent rock and soil composition

Vaselesa [24]

Soil is the result of chemical or physical weathering of a parent rock .this is so since the soil is just tiny particle of the huge parent rock and hence it affects soil composition . if the parent rock was made of limestone then the soil composition will constitute calcite and aragonite mineral elements from the limestone parent rock.

Which type of bonds hold two or more water molecules together

Afina-wow [57]

Answer:

Hydrogen bond.

Explanation:

It is an intermolecular bonding interaction between two molecules of different electronegative values or bonding between lone pairs of electron rich molecules.

Hydrogen-bonding forms in liquid water as the hydrogen atoms of one water molecule are then attracted towards the oxygen atom of a neighboring water molecule resulting in a general proton shared by two lone electron pairs.
