(HELP PLEASE) which pair would have an electrostatic force of attraction between them?
NISA [10]

Answer: K+ and P 3−

Explanation:

Electrostatic force of attraction is the attraction between different molecules that comes from them being electrically charged.

For molecules to have an electrostatic force of attraction, they need to have opposing charges because like charges repel each other but opposite charges attract.

In the question above, the only option that has opposing charges is option D so this is the correct option.

Alex dragged a log across the yard in 30 the log weighted 400n she did 900 j of work how much power did I she have
In-s [12.5K]

The power used by Alex to drag the log across the yard is determined as 2,656 W.

<h3>Mass of the log</h3>

The mass of the log is calculated as follows;

W = mg

m = W/g

m = (400)/9.8

m = 40.82 kg

<h3>Velocity of the log</h3>

K.E = ¹/₂mv²

v² = 2K.E/m

v² = (2 x 900)/(40.82)

v² = 44.096

v = 6.64 m/s

<h3>Power used by Alex</h3>

P = Fv

P = 400 x 6.64

P = 2,656 W
