What is one of Kepler's laws of planetary motion?
a.Planets move on elliptical orbits with the Sun at one focus.
b.Gravitational force between two objects decreases as the distance is squared.
c.An object in motion remains in motion.
d.Inner planets orbit in the opposite direction of outer ones.
Answers
Answer:
a. Planets move on elliptical orbits with the Sun at one focus.
Explanation:
Johannes Kepler was an astronomer who discovered that planets had elliptical orbits in the early 1600s (between 1609 and 1619).
The three (3) laws published by Kepler include;
I. The first law of planetary motion by Kepler states that, all the planets move in elliptical orbits around the Sun at a focus.
II. According to Kepler's second law of planetary motion, the speed of a planet is greatest when it is closest to the Sun.
Thus, the nearer (closer) a planet is to the Sun, the stronger would be the gravitational pull of the sun on the planet and consequently, the faster is the speed of the planet in terms motion.
III. The square of any planetary body's orbital period (P) is directly proportional to the cube of its orbit's semi-major axis.
Hence, one of Kepler's laws of planetary motion states that planets move on elliptical orbits with the Sun at one focus. This is his first law of planetary motion.
Answer:
Planets move on elliptical orbits with the Sun at one focus.

An isloated point charge produce an electric field with magnitude E at a point 2 m away. At a point 1 m from the charge magnitude of the charge is .. A. E B. 2E C. 4E D. E/2
Answers
Answer:
the correct answer is C, E’= 4E
Explanation:
In this exercise you are asked to calculate the electric field at a given point
E = [tex]k \frac{q}{r^2}[/tex]
indicates that the field is E for r = 2m
E = [tex]\frac{ k q}{4}[/tex] (1)
the field is requested for a distance r = 1 m
E ’= k \frac{q}{r'^2}
E ’= k q / 1
from equation 1
4E = k q
we substitute
E’= 4E
so the correct answer is C

Determine the kinetic energy of a 1000-kg roller coaster car that is moving with a speed of 20.0 m/s.
196000 N
200000 N
200000 J
196000 J
Answers
Answer:
The correct answer is - 200000 J
Explanation:
We use the formula of kinetic energy:
The formula to calculate kinetic energy is,
Here,
Ec =1/2 x m x v^2
The mass of the roller coaster is, m = 1000 k g
The speed of the roller coaster is, v = 20.0 m/s
Therefore,
Ec=1/2 x 1000kg x (20m/s)^2 = 200.000Joule
200,000J

question:
If all matter has a gravitational force, why don’t two tennis balls on the ground move towards each other on their own?
A. The force of gravity from the tennis balls is too small.
B.The tennis balls are outside of each other’s gravity field.
C.The tennis balls are too small to produce any gravity.
D.There is too much friction between the balls and the ground
(the picture is just of the question)
Answers
Answer:
Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces. So as two objects are separated from each other, the force of gravitational attraction between them also decreases.
When dealing with the force of gravity between two objects, there are only two things that are important – mass, and distance. The force of gravity depends directly upon the masses of the two objects, and inversely on the square of the distance between them.
Explanation:
I could be wrong but I would say B :)
Have a good day!
answer:
i believe the answer is d
explanation:
here's why;
c. is incorrect because everything has a gravitational force.
a. is also incorrect because gravity is what holds the tennis ball down and keeps it on the ground.
i don't really know how to explain why b. is wrong, but d. is the correct answer because the force of friction opposes the motion of an object, causing moving objects to lose energy and slow down.
good luck :)

“The fight or flight response, or stress response, is triggered by a release of hormones either prompting us to live and fight or run away and flee,” explains psychologist Carolyn Fisher, Ph.D. “during the response, all bodily systems are operating to maintain us alive in what we've perceived as a dangerous scenario
