Answer:
16.63265306 Kg
Explanation:
This is a Newtons to weight conversion.
Fg = weight
Fg = N/9.8
The second one is the answer
For resistors in series in a DC circuit, the potential difference is proportional to the resistance.
The voltage V across the 7.1 ohm resistor can be found from the proportion
V/7.1 = 12/4.8
V = 7.1*12/4.8 = 17.75
The potential difference at the battery terminals is the sum of the potential differences across the two series resistors.
Vbatt = 17.75 V + 12 V
Vbatt = 29.75 V
B)
The speed of the cart changed because it stopped.
