A 9.0 V battery has an internal resistance of 0.50 ? and is connected to 5 resistors, as shown in the figure below. A) What is the equivalent resistance of all the resistors (not including the internal resistance of the battery)? B) What is the total current in the circuit? C) What is the...
The Sun, on average, is 93 million miles from Earth. How many meters is this? Express using powers of ten. Express your answer using two significant figures.
Okay so: Okay so, 1 Meter = 1609.344 x 93 = 149668.992
1.5 x 10^5 (2 significant figures)
When I put 1.5x10^5 in, it says 'The...
