Overcurrent protective devices are normally installed in a branch circuit from where the conductors receive their supply.
<h3>What is resistance?</h3>
Resistance is the obstruction of electrons in an electrically conducting material. The mathematical relation for resistance can be understood with the help of the empirical relation provided by Ohm's law.
V=IR
V is the voltage,I is the current and R is the resistance
The vercurrent protective devices are normally installed in a branch circuit from where the conductors receive their supply.
Thus, In a branch circuit, overcurrent safety devices are often located from where the conductors get their supply.

So we want to know what is the age of igneous rock if it contains one half of its original amount of potassium 40. The half-life of potassium 40 is 1.251*10^9 years. Since in the igneous rock there is one half of potassium left it means only one half-life has passed. And its age is 1.251*10^9 years or 1.251 billion years.
Answer: its 19 m/sec
Explanation: gotta multiply the speed by 2 so 9.8 X 2 = 19
Answer:
i speak english sorrryyyyyyyyy
Answer:
You are exactly right. The molecules in hot air are moving faster than the molecules in cold air. Because of this, the molecules in hot air tend to be further apart on average, giving hot air a lower density. That means, for the same volume of air, hot air has fewer molecules and so it weighs less
