Planets in our solar system do not revolve around the sun in perfect circles. Their orbits are more like ovals. Which term do sc

ientist use to describe these orbits
Physics
1 answer:
enyata [817]4 years ago
6 0

Answer:

It is most likely the word elliptical.

Explanation:

Usually the term <em>elliptical </em>refers to the oval-like shape of a substance or path of an object.  The question states, "Planets in our solar system do not revolve around the sun in perfect circles. Their orbits are more like ovals."  Because the planets orbit around the sun in an oval-like path, those orbits can be described as <em>elliptical.  </em>Scientists also normally use this word to describe the same thing; Therefore, your answer is elliptical.

The polar coordinates of the collar A are given as functions of time in seconds by r = 2+ 0.7 t2 ft and ????= 3.5t rad. What are
r-ruslan [8.4K]

Answer with explanation:

Part a)

v_{radial}=\frac{dr}{dt}=\frac{d(2+0.7t^{2})}{dt}\\\\v_{radial}=1.4t\\\\\therefore v_{radial}|_{t=4}=1.4\times 4=5.6ft/s\\\\v_{angular}=r|_{t=4}\times \frac{d\theta }{dt}=13.2\frac{3.5t}{dt}=46.2fts^{-1}\\\\\therefore v=\sqrt{v_{radial}^{2}+v_{angular}^{2}}\\\\v=46.53ft/s

Part b)

a_{radial}=\frac{d^{2}r}{dt^{2}}=\frac{d^{2}(2+0.7t^{2})}{dt^{2}}\\\\a_{radial}=1.4ft/s^{2}\\\\a_{angular}=r\times \frac{d^{2}\theta }{dt^{2}}\\\\a_{angular}=r\times \frac{d^{2}(3.5t) }{dt^{2}}\\\\\therefore a_{angular}=0\\\\\therefore Accleration=1.4ft/s^{2}

How does the work needed to lift an object and the gravitational potential energy of an object compare
Ganezh [65]

When you do work to lift the object, the amount of work you do BECOMES the object's gravitational potential energy.  It GETS its potential energy from the work you do to lift it.  They're equal.  You lose it, and the object gains it.  Energy is not created or destroyed.  It's just transferred from you to the object.  

Later, when you DROP the object, GRAVITY does the same amount of work on it, to pull it to the ground.  Again, no energy is created or destroyed.  Every time a force acts to move anything, the energy to do it comes from somewhere, and the energy goes somewhere.

What is the relation between celsius and kelvin​
Scilla [17]

Answer:

The Celcius and kelvin scale are related unit for unit. One degree unit on the Celcius scale is equivalent to one degree unit on the kelvin scale. The only difference between these two scales is the zero point.

Which of these events is caused by contact forces? A. Jupiter's moons staying in orbit B. high tides occurring on the East Coast
elixir [45]

Correct option: D. Earthquakes along the San Andreas fault in California.

The earthquakes occur when the two plates collide with each other. Hence, there is contact between the two plates. So, the contact forces are responsible for the earthquakes.

The force responsible for Jupiter's moons to stay in orbit or the high tides occurring on the east coast is the gravitational force, which is not a contact force as there is no contact between Jupiter and its moon or the earth and the moon which is responsible for the high tides.

Moreover, the magnetic force is a non contact force as it attracts the pins from a distance without any contact between them.
