Answer:
The potential difference across the source is 30.45 V.
Explanation:
In this setup we have a voltage divider, we were given the voltage difference on one of the resistors, we know that the difference pottential from the source in this case is the sum of the voltage in each individual resistor, so we can use the following equation to solve this problem:
V_resistor5.4 = (V_source)*(R_5.4)/(R_5.4+R_8.3)
V_source = (V_resistor5.4)*(R_5.4+R_8.3)/(R_5.4)
V_source = (12)*(5.4+8.3)/5.4
V_source = (12)*(13.7)/5.4 = 30.45 V
he potential difference across the source is 30.45 V.
They can either cancel each other or add up to a resultant force with a certain direction and modulus.
Newton's second law states that F=m*a, where F is the resultant force, ie ΣF.
9.1 miles per hour because 2.2 is your hours right?
-- Bathroom tiles are usually cool, so water condenses on them
when you take a hot bath or shower in the room.
-- The natural result is that a smooth tile would become slippery,
exactly when you're walking around with wet feet and nothing on them ...
a dangerous situation.
-- In order to circumvent this safety hazard, the tiles in the bathroom
should be rough, especially on the floor.
