Answer:

First of All:: <em><u>The sun doesn't rotate us, we roate the sun...</u></em>

But to answer your question, it takes <u><em>24 hours</em></u> for us to revolve around the sun (aka 1 day, or 24 hours)

The potential energy between two atoms in a particular molecule has the form U(x) = 2.1 x 8 − 5.2 x4 where the units of x are le
a_sh-v [17]

Answer:

x\approx 0.948

Explanation:

The correct formula for the potential energy between two atoms in a particular molecule is:

U(x) = \frac{2.1}{x^{8}}-\frac{5.2}{x^{4}}

Where x is the distance.

According to the definitions of potential energy and work, as well as the Work-Energy Theorem and the Principle of Energy Conservation. The relation between that and related force is:

F = -\frac{dU}{dx}

The function is derived in terms of distance:

F (x) = \frac{84}{5\cdot x^{9}} -\frac{104}{5\cdot x^{5}}

Then, it is needed to find at least of x so that F(x) equals to 0.

\frac{84}{5\cdot x^{9}}-\frac{104}{5\cdot x^{5}}=0

\frac{84}{x^{4}}-104 = 0

84-104\cdot x^{4} = 0

x=\sqrt[4]{\frac{84}{104} }

x\approx 0.948

Define polarization (igcse answer please)
Dmitrij [34]

Answer:

the action of polarizing or state of being or becoming polarized: such as the action or process of affecting radiation and especially light so that the vibrations of the wave assume a definite form. Polarization, in Physics, is defined as a phenomenon caused due to the wave nature of electromagnetic radiation. There are two types of waves, transverse waves, and longitudinal waves.

An ant crawls along a sidewalk with a velocity of 0.1 m/s in a direction that is 45° relative to edge of the sidewalk. If it has
Marat540 [252]

Answer:14 s

Explanation:

Given

Velocity of ant is 0.1 m/s in a direction 45^{\circ}

if it has traveled 1 m perpendicular to the edge of the sidewalk

i.e. from diagram

\sin 45=\frac{1}{L}

L=\sqrt{2}

time=\frac{Distance}{speed}

t=\frac{\sqrt{2}}{0.1}

t=14.14 s

A car, moving along a straight stretch of highway,
yarga [219]
<span>We know that an object in moving with acceleration follow the rule according that the distance covered will be : d = Vi*t + 1/2*a*t^2 where d is distance, Vi is initial speed, and a is acceleration Then after 1 km which is 1000 metres we have: 1000 = Vi *71.2 + 1/2*0.0499*(71.2)^2 Vi = (1000-1/2*0.0499*(71.2)^2)/71.2 = 1000/71.2 - 1/2*0.0499*71.2 = 12.27 m/s Then the car was going at 12.27 m/s when started to accelerate.</span>
