Answer:

A and B are the correct answers.

Answer:

A and B are correct

Explanation:

<em>A</em> and <em>B</em> are the most logical answers from the 4 given. This is because just like the moon and Earth, Earth keeps the moon in its orbit with gravity.

A gravitational force can happen with any two objects in the universe. An example of this is a passing asteroid being pulled into Jupiter's atmosphere, because of the gravitational pull. Even two asteroids can have a gravitational pull/force on each other. If there is a big asteroid with smaller asteroids surrounding it, the smaller asteroids will "follow" the larger asteroid.

C is false, because the bigger the mass the bigger the pull (gravitational)

D is also false because if the gravitational force could only exist if there was contact, logically then the moon wouldn't still be orbiting Earth. In other words "Does the moon touch the Earth?" No, it does not "Is the moon still orbiting around Earth without contact?" Yes it is

Explain the significance of this quote, “Heisenberg may have slept here.”
ch4aika [34]

Umm...Well...

Heisenberg's Uncertainty Principle says that we can never know both the position and rate of change of a particle at any time. We can only know one or the other. This leads to rather silly jokes that deal with uncertainty, probability, and superposition. So, saying that "Heisenberg may have slept here" is essentially saying that it is uncertain if Heisenberg slept there or not, making for a rather silly, but slightly unfunny physics joke.

Compare the chemical reactivity of chlorine and bromine. Explain your answer. Thanks in advance

Bromine vs Chlorine | Br vs Cl

 

Halogens are group VII elements in the periodic table, and all are electronegative elements and have the capability to produce -1 anions.

Bromine

Bromine is denoted by the symbol Br. This is in the 4th period of the periodic table between chlorine and iodine halogens. Its electronic configuration is [Ar] 4s2 3d10 4p5. The atomic number of bromine is 35. Its atomic mass is 79.904. Bromine staChlorine is an element in the periodic table which is denoted by Cl.  It is a halogen (17th group) in the 3rd period of the periodic table. The atomic number of chlorine is 17; thus, it has seventeen protons and seventeen electrons. Its electron configuration is written as 1s2 2s2 2p6 3s2 3p5. Since the p sub level should have 6 electrons to obtain the Argon, noble gas electron configuration, chlorine has the ability to attract an electron. ys as a red-brown color liquid at room temperature.

A condor has a wing span of 3.05 m. What is the wing span in feet
romanna [79]

Answer:

The condor has a wing span of 10 feet

Explanation:

This can be solved by a simple rule of three

In a rule of three problem, the first step is identifying the measures and how they are related, if their relationship is direct of inverse.

When the relationship between the measures is direct, as the value of one measure increases, the value of the other measure is going to increase too. In this case, the rule of three is a cross multiplication.

When the relationship between the measures is inverse, as the value of one measure increases, the value of the other measure will decrease. In this case, the rule of three is a line multiplication.

In this problem, our measures are the wing span of the condon in meters and the wing span of the condor is feet. As the value of one of these measures increases, the other is going to increase too.

We know that 1m has 3.281 feet,

So we have the following rule of three:

1m - 3.281 feet

3.05m - x feet

x = 3.821*3.05

x = 10 feet

The condor has a wing span of 10 feet
