Answer:
Resistance,
Explanation:
Given that,
Voltage of the battery, V = 9 volts
Current produced in the circuit, I = 17 A
We need to find the resistance when shorted by a wire of negligible resistance. It is a case of Ohm's law. The voltage is given by :
So, the resistance in the circuit is 0.529 ohms. Hence, this is the required solution.
Answer:
-2200 N
Explanation:
Here we can use the impulse theorem, which states that the impulse exerted on Sarah (product of force and duration of collision) is equal to Sarah's change in momentum:
where
F is the average force
is the duration of the collision
m is the mass
is the change in velocity
In this problem:
m = 55 kg
Solving the formula, we find the force exerted by the seatbelt on Sarah:
And the negative sign means the direction is opposite to that of Sarah's initial motion.
Answer:
Explanation:
The equilibrium equation is:
The initial concentration of A can be calculated from the ideal gas equation:
Determine the conversion of substance A to substance C using an ICE table and the Kc constant:
A ⇄ 3C
I 0.304 0
C - x + 3x
E 0.304 - x 3x
Solve for x:
You need to use a graphing calculator:
Then:
The equilbrium conversion is:
