(1 of 10) What is the cosmic horizon? The maximum distance from us through which light from any object has had time to travel since the Big Bang. A space probe tasked with measuring the temperature of the cosmic microwave background radiation. The distance at which the curvature of the Universe prohibits us from seeing over the horizon. The distance from a black hole at which the escape velocity is equal to the speed of light.

Question 2 (2 points) Why is Ohm's Law relevant? Ohms law is extremely important to the world of electrical circuits and components but is not suitable for every electrical circuit and application. There are certain requirements that a circuit and electrical component should meet to ensure that Ohms law is applicable. Ohms law can be used to calculate the required value of Voltage or components within a circuit, it can also work out the amount of current that flows in an electrical circuit when resistors can be measured across electrical components such as voltage. Ohm's Law is not relevant Ohm's Law is only used in a DC circuit.
