<h3><u>Answer;</u></h3>
B. 3.43 kPa
<h3><u>Explanation</u>;</h3>
Pressure is given by the formula;
Pressure = Force / Area
Force is the product of mass and acceleration due to gravity.
Thus; Force = mass x acceleration due to gravity
Substituting;
Force = (350 kg) x (9.8 m/s²)
Force = 3430 N
Then, using the first equation;
Pressure = 3430 N / 1m² or Pa
<h3> <u>= 3.43 kPa</u></h3>

Answer:
The current doubles
Explanation:
In a circuit, Ohm's law gives the relationship between voltage, current and resistance:
where
V is the voltage
R is the resistance
I is the current
In this problem,
V is held constant
R is halved:
Therefore, the new current is
So, the current doubles.
