How many factors affect acceleration

2 answers:

8 0

There are two of them:

1). The mass of the object;

2). The net of all forces acting on the object.

As soon as you know these two things, you have everything
you need to know to determine the object's acceleration.

Well it all depends on the acceleration your trying to find. if its the terminal speed of a falling object then its only its mass and the acceleration due to gravity

Endometriosis, cysts, pelvic infections, and allergic reactions can all cause

D. Dyspareunia
I would say d because dyspareunia means painful sex so endometriosis, cyst, pelvic infections, and allergic reactions can all cause this.

HURRY!!!!! Which change of state is shown into the model?

nadezda [96]

Option (B) is correct. The process shown in the model is the process of DEPOSITION.

Explanation:

The first container shows the molecules of the substance present inside it at a fairly large distance from one another whereas the second container, the molecules of the substance are very close to each other.

This shows that the substance in the first container is gaseous in nature whereas the substance in the second container is solid in nature as its molecules are closely packed.

Therefore, it shows the phase transition of a substance from gaseous sate to the solid state. The process of conversion of a gas directly into a solid is termed as deposition. This process is the opposite of the Sublimation in which the solid gets directly converted into a gas. Thus, the process is also termed as desublimation.

Thus, Option (B) is correct. The process shown in the model is the process of DEPOSITION.

An ion's position vector is initially r with arrow = 7.0i hat â 7.0j + 1.0k, and 5.0 s later it is r with arrow = 7.0i hat + 7.0

harkovskaia [24]

<h2>Answer:</h2>

Shown in the explanation

<h2>Explanation:</h2>

Position vector of a particle at a given instant is given by:

$\vec{r}=x\hat{i}+y\hat{j}+z\hat{k}$

On the other hand, the average velocity is the change in the particle’s position vector divided by time interval:

$\vec{v}=\frac{\Delta \vec{r}}{\Delta t}=\frac{\vec{r_{2}}-\vec{r_{1}} }{t_{2}-t_{1}} \\ \\ \\ Where: \\ \\ \\ \vec{r_{1}}: Initial \ position \\ \\ \vec{r_{2}}: Final \ position \\ \\ t_{1}:Initial \ time \\ \\ t_{2}:Final \ time$

So we have:

$\vec{r_{1}}=7\hat{i}+7\hat{j}+1\hat{k} \\ \\ \vec{r_{2}}=7\hat{i}+7\hat{j}+8\hat{k} \\ \\ \\ Then: \\ \\ \Delta \vec{r} = \vec{r_{2}}-\vec{r_{1}}=7\hat{i}+7\hat{j}+8\hat{k}-(7\hat{i}+7\hat{j}+1\hat{k}) \\ \\ \Delta \vec{r}=7\hat{k} \\ \\ \\ We \ also \ know: \\ \\ \Delta t=5s$

Finally, the average velocity is:

$\vec{v}=\frac{\Delta \vec{r}}{\Delta t} \\ \\ \\ \vec{v}=\frac{7\hat{k}}{5} \\ \\ \boxed{\vec{v}=\frac{7}{5}\hat{k} \ units/s}$
