In astronomy, Johannes Kepler published his three laws about planetary motion. It is one of the most important things in astronomy. So Kepler gives three laws about planetary motion.

<h3>What is motion?</h3>

Motion is a physical term in physics. If a particle of mass m and affected by some force F then it change its position in many different way. That is the motion of the object. It is a vector quantity.

<h3>What is Kepler's three laws?</h3>

In astronomy, Johannes Kepler published his three laws about planetary motion between 1609 and 1619. This shows about motion describe the orbits of planets around the Sun. So the three motions are shown following,

<u>First law</u>: Every planet in solar system that moves in a elliptical orbits where the sun always in the center of the motion.

<u>Second law</u>: Every planet covers the same amount of distance in a constant time no matter where the orbit of the planet placed. That means the velocity of every planet is not same. It varies along with the orbit. But every time the change of area is constant.

<u>Third law</u>: The orbital period of the planet is proportional with the cube of the semi major axis of the planet. It can be shown mathematically,

p²∝a³

Where we know,

p= The orbital period of the planet.

a= the semi major axis of the planet.

From the discussion we can easily shown that there are three laws of Kepler about planetary motion.

A mover uses a ramp to push a stereo into the moving van. The ramp is 3 meters long and 1.5 meters high. What is the ima of this
densk [106]

Mechanical advantage<span> <span>is a measure of the force amplification achieved by using a tool, </span>mechanicaldevice or machine system. Ideally, the device preserves the input power and simply trades off forces against movement to obtain a desired amplification in the output force. The model for this is the law of the lever. So the ima is 3/1.5 = 2</span>

JUST PLZ HELP!!! Why does the lightbulb in the right electrical circuit turn on but not the one on the left?
jekas [21]

In the open circuit the current can not flow from one end of the power source to the other. Because of this there is no current flow, and therefore the light does not turn on.

a truck is moving around a circular curve @ a uniform velocity of 13m/s. if the centifrical force on truck is 3,300N with truck
VMariaS [17]

<u>Answer</u>

81.94 m


<u>Explanation</u>

The centripetal force of an object moving in a circular path is given by:

F = mv²/r  Where m is the mass of the object, v is the constant velocity and r is the radius of the curve.

F = mv²/r

3,300 = (1600×13²)/r

3,300 = 270,400/r

r = 270,400/3,300

  = 81.94 m
