A 15 kg ball moving to the right at 2.0 m/s makes an elastic head-on collision with a 30 kg ball moving to the left at 1.5 m/s.

After the collision, the smaller ball moves to the left at 3.0 m/s. Assume that neither ball rotates before or after the collision and that both balls are moving on a frictionless surface. What is the velocity of the 30 kg ball after the collision?​

A simple circuit consists of a light bulb connected to the terminals of a battery. A voltmeter shows a potential difference of 1
larisa [96]
<h2>Answer:</h2>

38.14Ω

<h2>Explanation:</h2>

Let's solve this question using Ohm's law which states that the current (I) flowing through a conductor is directly proportional to the potential difference or voltage (V) across it. Mathematically;

V =  I R       -------------------(i)

<em>Where</em>;

R is the constant of proportionality called resistance of the conductor and is measured in Ohms (Ω)

<em>From the question;</em>

V = 18.5V

I = 0.485A

<em>Substitute these  values into equation (i) as follows;</em>

18.5 = 0.485 x R

<em>Solve for R;</em>

R = 18.5 / 0.485

R = 38.14Ω

Therefore the resistance of the bulb is 38.14Ω
