How do you identify short and long term comets

Physics
1 answer:
erica [24]3 years ago

A second important difference between comets coming from the Kuiper Belt and from the Oort cloud is represented by their different characteristic periods.
In fact, short period comets are thought to generate in the Kuiper belt and have rather predictable orbits with short periods (up to 200 years). There are two major families of short period comets: the Jupiter family with periods of less than 20 years and the Halley family with periods form 20 to 200 years. That's short

What is the momentum of a vehicle that has a mass of 1500kg and a velocity of 15m/s? (don't forget the unit is kg*m/s, and needs
alex41 [277]

Answer:

<h2>22500 kg.m/s</h2>

Explanation:

The momentum of an object can be found by using the formula

momentum = mass × velocity

From the question we have

momentum = 1500 × 15

We have the final answer as

<h3>22500 kg.m/s</h3>

Hope this helps you

You move a 2.5 kg book from a shelf that is 1.2 m above the ground to a shelf that is 2.6 m above the ground. What is the change
Sophie [7]
The change in potential energy of an object is given by
U=mg \Delta h
where
m is the mass of the object
g is the gravitational acceleration
\delta h is the increase in altitude of the object

In our problem, m=2.5 kg is the mass of the book, g=9.81 m/s^2 and 
\Delta h=2.6 m -1.2 m=1.4 m is the increase in altitude of the book, so its variation of potential energy is
U=mg\Delta h=(2.5 kg)(9.81 m/s^2)(1.4 m)=34.3 J

PLEASE HELP SOMEONE!!! An object is located 5.0 cm from a convex lens. The lens focuses light at a distance of 10.0 cm. What is
OverLord2011 [107]

Answer:

-10.0 cm

Explanation:

OK so in the equation they're having you use the variables are:

d_o = 5.0 cm\\\\f = 10.0 cm\\\\d_i = ?

So we simply plug in the variables:

d_i = \frac{d_of}{d_o-f} \\\\d_i = \frac{5.0 * 10.0}{5.0 - 10.0}\\\\d_i = \frac{50}{-5}\\\\d_i = -10.0 cm
