Avg sped = total distance/ total time = 1350 mi/ 5 hrs= 270mph (i dont know if ur teacher wants you to convert this to m/s)
300miles are traveled in 1 hr. So, 300 *2hrs = 600 miles south
750/250= 3hrs north
Total distance = 600 miles + 750 miles= 1350 miles
Total time is = 3hrs + 2hrs= 5hrs
Answer:
Approximately .
Explanation:
It is given that and are connected in a circuit in parallel.
Assume that this circuit is powered with a direct current power supply of voltage .
Since and are connected in parallel, the voltage across the two resistors would both be . Thus, the current going through the two resistors would be and , respectively.
Also because the two resistors are connected in parallel, the total current in this circuit would be the sum of the current in each resistor: .
In other words, if the voltage across this circuit is , the total current in this circuit would be . The (equivalent) resistance of this circuit would be:
.
Given that and :
.
Answer: The electrons flowing through the wire are referred to as a quantity of electricity, and the flow of electricity is referred to as “an electric current.”
