<span>D. 2S + 3O2 right-pointing arrow 2SO3 Let's look at the 4 options and see what the issues are with each of the wrong ones. A. Sulfur and oxygen react to form sulfur trioxide. * This is just a quick description, but nothing quantitative. How much sulfur? How much oxygen? Are the reactants single atoms or molecules? Not enough information, so this is the wrong choice. B. S and O2 produce SO3. * Just replacing words with element abbreviations does't fix the problem. So it's still wrong. C. S + O2 right-pointing arrow SO3 * This is getting closer. We have the correct symbols for the reactants and product. But the equation doesn't balance. On the left hand side, there are 2 oxygen atoms and on the right hand side, there's 3. Where did the 3rd oxygen atom come from? So it's still wrong. D. 2S + 3O2 right-pointing arrow 2SO3 * This is correct. We know that we're using elemental sulfur and an oxygen molecule on the left hand side. Actually 2 atoms of elemental sulfur and 3 molecules of oxygen gas. And we're producing 2 molecules of sulfur trioxide. And the numbers of each type of atom match in count on both sides. So this is the correct answer.</span>

During a baseball game, a batter hits a high pop-up. If the ball remains in the air for 4.02 s, how high above the point where i
alukav5142 [94]

Answer:

d = 19.796m

Explanation:

Since the ball is in the air for 4.02 seconds, the ball should reach the maximum point from the ground in half the total time, therefore, t=2.01s to reach maximum height. At the maximum height, the velocity in the y-direction is 0.

So we know t=2.01, vi=0, g=a=9.8m/s and we are solving for d.

Next, you look for a kinematic equation that has these parameters and the one you should choose is:

d=vt+\frac{1}{2}at^2

Now by substituting values in, we get

d=(0\frac{m}{s})*(2.01s)+\frac{1}{2}(9.8\frac{m}{s^2})(2.01)^2

d = 19.796m

How much is the velocity of a body when it travels 600m in 5 minutes?( with the full process)​
Tcecarenko [31]
Its average speed, pretending that it traveled at a constant speed, is

v = s / t

= 600 m

5 x 60 s

= 2 m/s

but to be a velocity it needs a direction as well as a speed.

( Sorry. Can’t find a division line to put between the 600 m and the 5 x 60 s )

What is the mass of an object that has an acceleration of 2.63m/s2 when a unbalanced force of 112N is applied to it?
exis [7]

Answer:

42.58kg

Explanation:

By Newton's second law, F = ma.

F is the force being applied, in this case 112N. a is the acceleration, in this case 2.63 m/s^2.

Thus, with some simple algebraic manipulation, we get the mass to equal:

m = F/a = 112N / 2.63 m/s^2 = 42.58kg

strojnjashka [21]

One of the most important aspects of civilization is communication.

People need one another, and in order for them to communicate and understand one another, they must be able to understand one another. The communication cycle explains how the mechanism of message transmission and comprehension works.

Although different cycles may have slightly varied phases and descriptions, the fundamental components are often the same:

Sender: the sender of communication is a person or an organization.

Message: The details the sender wants to share

Encoding is the process the sender uses to transform the message into one that can be sent.

The channel is the method used to send the message.

recipient: the individual or thing to whom the communication is

Decoding: How the communication is interpreted and comprehended by the recipient

Feedback: the reaction of the recipient
