The forces that attract the sun and the planet toward
each other are described almost exactly by Newton's
law of universal gravitation.

In order to derive the existence of orbits, you also need
Newton's second law of motion.

Once you have properly mashed and massaged these two
laws together on paper, you GET Kepler's law of ellipses,
plus Kepler's other two laws of planetary motion. 

It's really a beautiful math exercise and experience. 
The agreement is so perfect that it gives you, right there on
your paper, powerful powerful arguments for the correctness
and accuracy of both Kepler's laws AND Newton's laws.
(But not proofs.  They're all "only theories".)

Answer: Newton's law of universal gravitation

Explanation:

We know that an object does not change its state of rest or motion unless and until an external unbalanced force acts on it.  Planets would have continued to move in straight path if they would have not pulled towards the Sun due to gravity. Gravitational pull of the Sun is the reason why the planets are pulled towards the Sun and orbit it.

Hence, Newton's law of universal gravitation which states that gravitational force exists between any two bodies having mass is the correct answer.

Bob will not develop a good habit if he _____. works out for only one week develops a consistent schedule of exercise works out
Charra [1.4K]

Answer:

works out for only one week

Explanation:

In order to develop a good habit, there are certain things that you can do like:

-Develop a consistent schedule of exercise which allows you to work everyday over a period of time which helps you to create a routine that you would get used to it creating a habit.

-Work out with a friend which allows you to have someone to motivate you and that would go everyday with you which would help to be consistent.

-Use success strategies that are ways in which you can achieve your goal of creating a good habit to exercise.

According to this, the option that would not help Bob develop a good habit is if he works out for only one week as doing something everyday is what would help you to create the habit.

A 1.2 L weather balloon on the ground has a temperature of 25°C and is at atmospheric pressure (1.0 atm). When it rises to an el
Irina-Kira [14]

Answer:

71.19 C

Explanation:

25C = 25 + 273 = 298 K

Applying the ideal gas equation we have

\frac{P_1V_1}{T_1} = \frac{P_2V_2}{T_2}

where P, V and T are the pressure, volume and temperature of the gas at 1st and 2nd stage, respectively. We can solve for the temperature and the 2nd stage:

T_2 = T_1\frac{P_2V_2}{P_1V_1} = 298\frac{0.77*1.8}{1.2*1} = 298*1.155 = 344.19 K = 344.19 - 273 = 71.19 C
