Based on the number of positive and negative charges

<u>Explanation</u>:

  1. In a positive charge particle, the  number of proton is higher than the number of electron. Due to this fact alone, we can come to the conclusion that positive charge consists of more number of protons than electrons.
  2. In a negative charge particle, the  number of electron is higher than the number of proton. Due to this fact alone, we can come to the conclusion that negative charge consists of more number of electrons than protons.

Helga [31]

Answer:

2.59 m

Explanation:

Coordinates of origin = (0, 0)

Coordinates of Point p where the fly reach = (2.3 m, 1.2 m)

Use the distance formula of coordinates to find the distance between the origin and the point P.

d=\sqrt{\left ( x_{2}-x_{1} \right )^{2}+\left ( y_{2}-y_{1} \right )^{2}}

d=\sqrt{\left ( 2.3- 0 \right )^{2}+\left ( 1.2-0 \right )^{2}}

d = 2.59 m

Thus, the distance between the origin and the point P is 2.59 m.

At $.110 per kWh, what does it cost to leave a 40-W porch light on day and night for a year?
nlexa [21]

The cost of electricity be  $ 38.544.

<h3>What is electricity?</h3>

Electricity is the passage of charges in a conductor. From one end of the terminal to the other, charges are transmitted. Usually, the terminal moves from positive to negative. Since the nucleus holds the electrons loosely, they can move freely throughout the body.

Watts are units of power used to measure electrical output. 

Price of electricity is $ 0.110 per kWh .

If a 40-W porch light on day and night for a year, total amount of electricity spend = power of the bulb × time

= 40 W × 1 year

= 40 W × 365 day

= 40 W × 365 ×24 h

= 350400 Wh

= 350.4 kWh.

Hence,  the cost of electricity be = $350.4 × 0.110 =  $ 38.544.
