Answer:

I1 = ε/R1

I2 = ε/R2

I3 = ε/R3

Explanation:

From the image, we see that the resistors are connected in parallel. This means that the voltage passing through them is the same.

Now, formula for current is; I = V/R

In this case, V which is voltage is denoted by ε.

Thus;

I1 = ε/R1

I2 = ε/R2

I3 = ε/R3

**Answer:**

kinetic energy = 20 J

**Explanation:**

KE = ½mv²

= ½× <u>100 </u> × 20 × 20

1000

KE = 20 J//

Answer:

44 Ohms

Explanation:

Use Ohm's law:

(Resistance) = (Voltage) / (Current)

(Resistance) = 88V / 2 A = 44 Ohms

**Answer:**

Nicolaus Copernicus

**Explanation:**

In 1543, Nicolaus Copernicus detailed his radical theory of the Universe in which the Earth, along with the other planets, rotated around the Sun. His theory took more than a century to become widely accepted.
