.Please explain to me how to find the momentum

Answers

Answer 1

Answer:

Answer:

momentum = mass x velocity

Explanation:

So ultimately, find the mass of the object (be careful since this is not the same as weight. Weight is your gravitational pull to the earth. This means that your weight different amounts on different planets. But mass stays the same on all planets, it's what most people call their weight.) and then find the velocity (2 meters/second north, etc.)

Now you can apply this to your problem

Which of these locations on earth experiences at least change in the number of daylight hours throughout the year?a) North pole
b) terrestrial equator
c) tropic of Capricorn
d) tropic of Cancer
e) South pole

Answers

The equator does. There, the noontime sun is never more than 23.5 degrees
from directly overhead, and the rising/setting sun is never more than 23.5 degrees
from due east/west.

So this is the place where the path of the sun across the sky changes the
least during the year, and therefore the place where the lengths of day and
night change the least during the year.

B the equator for it is the middle of the earth hope this helps

A 139 kg physics professor has fallen into the Grand Canyon. Luckily, he managed to grab a branch and is now hanging 89 m below the rim. A student (majoring in linguistics and physics) decides to perform a rescue/experiment using a nearby horse. After lowering a rope to her fallen hero and attaching the other end to the horse, the student measures how long it takes for the horse to pull the fallen physicist to the rim of the Grand Canyon. The acceleration of gravity is 9.8 m/s 2 . If the horse’s output power is truly 1 horsepower (746 W), and no energy is lost to friction, how long should the process take? Answer in units of s.

Answers

In order to lift the fat (306 lb) physics professor 89 meters up to
the rim, he'll need more potential energy, equal to

(mass) x (gravity) x (height) = (139 x 9.8 x 89) = 121,236 joules .

If the faithful horse delivers 1 constant horsepower = 746 watts,
AND if the cute-as-a-button student has instantly figured out a
way to keep the rope sliding around the edge without any friction,
then the soonest Prof. Tubby can arrive at the rim is

(121,236 joules) / (746 joules/sec) = 162.5 seconds .

Nowhere in this tense drama has the student needed her linguistics
skill yet, but I'll bet it comes in handy as she attempts gamely to
comprehend all of the various pleadings, prayers, and expletives
uttered by her heavy hero from the time he falls over the rim until
he's again lifted to it.

The Milankovitch cycles may have changed Earth's climate in the past. These cycles involve _____.volcanic activity on Earth
plate tectonics
Earth's tilt and orbit
sunspots

Answers

The Milankovitch cycles describe the effects of changes in Earth's movement on the climate over a long period of time. These cycles involve variations in things such as eccentricity (orbital shape), axial tilt along with axial precession. This results in changes in the solar radiation which reaches the Earth and thus affects the climate. The correct answer is Earth's tilt and orbit.

I had a different quiz, different question, same answer:

Which of these contributes to the creation of Milankovitch cycles?

B:Changes in Earth's axial tilt

Describe the conversions between potential and kinetic energy that occur when you shoot a basketball at a basket

Answers

When you shoot a basketball at a basket, the energy from your hands is transferred into the basketball. When you hold the ball up in preparation to shoot, it has potential energy, meaning that it has stored energy that can turn into kinetic energy. When you shoot it, that potential energy turns into kinetic energy, causing the basketball to move.

How much work is done on a a 60 n box of books that you carry horizontally across a 6 m room?

Answers

W = F x s cos thita.
= 60 x 6 x cos thita
since it is horizontal, thus the angle will be 90 degrees.
Thus, W = FS 90 degree.
Since the angle is 90 degree, cos thita will become zero.

thus, W = 60 x 6 x 0
=0
Thus, work done will be zero.

the work done on a a 60 n box of books that you carry horizontally across a 6 m room is 0
