You have two flashlights that have 0.500-A currents flowing through them. One flashlight has a single 1.50-V battery in its circuit, and the second flashlight has three 1.50-V batteries connected in a chain that provides 4.50 V. How much power is the battery in the first flashlight providing

0.75 W

Explanation:

Given

Current flowing

The first flashlight has a single 1.5 V battery

The second flashlight has three 1.5 V batteries connected to provide 4.5 V

Power is the product of voltage and current.

For the first flashlight

Thus, the first flashlight providing 0.75 W of power.

305.7

explanation:

density =m/v

density =917/3.00

density = 305.

approximately = 305.7
