I do, and my brother and son-in-law can also solve it.

Note: V1, V2, V3, I1, I2, and I3 are not labeled in the picture, so those can't be solved for.

Eric a chemist is running tests with four unknown elements he has found that they all bond the same way so he knows that they ar

nasty-shy [4]

The elements most likely are halogens because if we talk about manner of bonding they all are diatomic molecules and need one electron to fill their outermost shell. That is why they bond with other atom of own type and exist as diatomic molecule in pure state. However, all halogens are so reactive that they react with metals through strongest type of ionic bonds and form salts.

They all tend to form salts when they react with metals like NaCl and that is why they are commonly known as salt dormers.

They perfectly show significant trends in some properties like atomic radius increases from top to bottom, boiling and melting temperature increase down the group and electronegativity value decrease from top to bottom.

The elements belong to group 17.

Hope it helps!

Two forces P and Q act on an object of mass 15.0 kg with Q being the larger of the two forces. When both forces are directed to

Rom4ik [11]

Answer:

P=6.25N and Q=16.25N

Explanation:

In order to solve this problem we must first draw a free body diagram for both situation, (see attached picture).

Now, we need to analyze the two free body diagrams. So let's analyze the first diagram. Since the body is accelerated, then the sum of forces is equal to mass times acceleration, so we get:

$\Sigma F=ma$
