Consider Earth and the Moon. As you should now realize, thegravitational force that Earth exerts on the Moon is equal andopposit

dolphi86 [110]

Answer:

A. the Moon has a larger acceleration than Earth, because it has a smaller mass.

Explanation:

A. the Moon has a larger acceleration than Earth, because it has a smaller mass.

According to Newton's second law F=ma, if we solve for a we have that

a=F/m, the smaller the mass the larger the acceleration given the force is the same, in this case the moon has a smaller mass and therefore a larger acceleration

Which of the following are not correctly balanced reactions?

expeople1 [14]

Answer:

B. 2K + Br2 + 2KBr

D. C + 02 → CO2

Explanation:

In balancing a chemical reaction, the number of atoms on both sides of the expression must be the same in order to obey the law of conservation of mass.

According to the law of conservation of mass, in a chemical reaction, matter is neither created nor destroyed.

So, let us investigate:

Number of atoms

Reactants Products

K 2 2

Br 2 2

C + 0₂ → CO₂

C 1 1

O₂ 2 2

We see that for both equations, the number of atoms on both sides of the expression is the same.

If little herbert does something uncon<br> sciously he will probably

snow_tiger [21]

If little herbert does something unconsciously he will probably, he's definitely very unware of he has done

Doing something unconscious may have some implications which may not be favourable.

<h3>What is unconscious?</h3>

Unconscious simply means a state of someone being absent minded of what is happening to him or her at a particular period of time

So therefore, if little herbert does something unconsciously he will probably, he's definitely very unware of he has done

B h combining g two hydrogen atoms ans one oxygen atom for a molecule of water is made from

vivado [14]

The correct answer to this question is this one:

By definition, if a molecule is composed of two hydrogen atoms and one oxygen atom, that molecule is a water.<span> In fact, the structure of water is written as H20, which signifies that two hydrogen (H) atoms and one oxygen (O) atom make up the molecule.</span>

A 0.3-m-radius automobile tire rotates how many revolutions after starting from rest and accelerating at a constant 2.13 rad/s2

Aloiza [94]

Answer:

The automobile tire rotates 91 revolutions

Explanation:

Given;

angular acceleration of the automobile, α = 2.13 rad/s²

time interval, t = 23.2-s

To calculate the number of revolutions, we apply the first kinematic equation;

$\theta = \omega_i \ + \frac{1}{2} \alpha t^2$

the initial angular velocity is zero,

$\theta =0\ + \frac{1}{2} (2.13) (23.2)^2\\\\\theta = 573.2256 \ Rad$

Find how many revolutions that are in 573.2256 Rad

$N = \frac{\theta}{2 \pi} = \frac{573.2256}{2\pi} \\\\N = 91 \ revolutions$

Therefore, the automobile tire rotates 91 revolutions
