What is electropositivity and electronegativity? Between group 1 and group 17, which is electropositive and electronegative?

1 answer:

3 0

Electronegativity is a chemical property that describes the tendency of an atom or a functional group to attract electrons towards the nucleus. Electropositivity on the other hand is <span>a measure of an element's ability to donate electrons. Group 1 is a group of metals hence they are electropositive while group 17 is electronegative</span>

An electric field is produced by the very long, uniformly charged rod drawn above. If the strength of the electric field is E1 a

Debora [2.8K]

Answer: hello the complete question is attached below

answer :

r2 = 4r1

Explanation:

Electric field strength = F / q

we will assume the rod has an infinite length

For an infinitely charged rod

E ∝ 1/ r

considering two electric fields E1 and E2 at two different locations as described in the question

E1/E2 = r1/r2 ----- ( 2 )

<u>Calculate for r2 when E2 = E1/4 </u>

back to equation 2

E1 / (E1/4) = r1 / r2

∴ r2 = 4r1

A runner achieves a velocity of 11.1 m/s, 9 sec after he begins. What is his

Elena-2011 [213]

Answer:

1.23 m/s²

Explanation:

Given:

v₀ = 0 m/s

v = 11.1 m/s

t = 9 s

Find: a

Equation:

v = at + v₀

Plug in:

11.1 m/s = a (9 s) + 0 m/s

a = 1.23 m/s²

The runner's acceleration is 1.23 m/s².

A decrease in the magnitude of the velocity is called

allochka39001 [22]

That's one of the three changes that are called "acceleration".

The other two are:

-- increase in the magnitude

-- change in direction.

Some might call a decrease in the magnitude "deceleration".
