Answer:

Average velocity (v) of an object is equal to its final velocity (v) plus initial velocity (u), divided by two.

v¯¯¯=(v+u)2

Where:

v¯¯¯ = average velocity

v = final velocity

u = initial velocity

The average velocity calculator solves for the average velocity using the same method as finding the average of any two numbers. The sum of the initial and final velocity is divided by 2 to find the average. The average velocity calculator uses the formula that shows the average velocity (v) equals the sum of the final velocity (v) and the initial velocity (u), divided by 2.

Radon-222 transforms into polonium-218 and an alpha particle (he-4). what else is created?
ELEN [110]
Hm pretty much that's all for alpha decay... But always after any alpha or beta decay, gamma photons are released because the daughter products end up in an excited state so they have to release energy through gamma decay

Suppose you increase your walking speed from 6s to 12 m/s in a period of 2 s. What is acceleration
ElenaW [278]

As we know that acceleration is given as

a = \frac{v_f - v_i}{t}

here we know that

v_i = 6 m/s

v_f = 12 m/s

\Delta t = 2 s

now we will have

a = \frac{12 - 6}{2}

a = 3 m/s^2

so acceleration will be 3 m/s^2

If a substance can be separated by physical means and it is not the same throughout, what is it?
TEA [102]

Answer:

Option (B)

Explanation:

A heterogeneous mixture is usually defined as a combination of two or more chemical substances. It can be also elements as well as compounds. These contrasting components can be easily separated from one another by means of physical process. These are comprised of substances that are not even everywhere. There is variation in it.

Thus, the correct answer is option (B).
