sergejj [24]

Answer:

Both technicians A and B are correct, the information on how to fill the car tires can be located on the tire and on the placard on the driver's door jam

Explanation:

The instruction on proper inflation of car tires can be found on the tire information placard in the door jam area or the fuel filler door, in the glove box or in the car or tire manual

The tire information of the proper pressure to fill the tires is also visibly engraved on the sides of the car tire, where other information such as the requirement for training on tire filling/changing, safety precautions and manufacturer's information

In a closed circuit containing one resistor and a battery, if the voltage in the battery increases, the current going through th
Stells [14]

ANSWER:

C) as the electrons are pushed more by the battery, they move faster through the circuit

EXPLANATION:

Electrons move very slowly. When we supply voltage the current through a wire moves which causes each electron to move in the direction of the flow of current, the electrons which were in random motions previously now move in one direction which is the direction of current,the more we supply the current the faster electrons will move in the circuit,which will cause the current to increase with increase in voltage.

Two identical capacitors are connected parallel. Initially they are charged to a potential V0 and each acquired a charge Q0. The
MrRa [10]

Answer:

Explanation:

capacitance of each capacitor

C₀= Q₀ / V₀

V₀ = Q₀ / C₀

New total capacitance = C₀ ( 1 + K )

Common potential

= total charge / total capacitance

= 2 Q₀ / [ C₀ ( 1 + K ) ]

2 V₀ / ( 1 + K )

b )

Common potential = 2 x V₀ / ( 1 + 7.8 )

= .227  V₀

charge on capacitor with dielectric

= .227  V₀ x 7.8 C₀

= 1.77 V₀C₀

= 1.77 Q₀

Ratio required = 1.77
