I believe the best answer is B. Waking State
Answer:
U = 12,205.5 J
Explanation:
In order to calculate the internal energy of an ideal gas, you take into account the following formula:
(1)
U: internal energy
R: ideal gas constant = 8.135 J(mol.K)
n: number of moles = 10 mol
T: temperature of the gas = 100K
You replace the values of the parameters in the equation (1):
The total internal energy of 10 mol of Oxygen at 100K is 12,205.5 J
Answer:
False
Explanation:
The current flowing through a circuit can be computed by using Ohm's law:
where
V is the voltage of the battery
Req is the total resistance of the circuit
Let's now compare the two situations. Let's call R the resistance of each resistor (since they are identical, they have same resistance, R)
- Series configuration: in this case, the total resistance of the circuit is given by
So the current through the circuit is
(1)
- Parallel configuration: in this case, the total resistance of the circuit is given by
So the current through the circuit is
(2)
By comparing (1) and (2), we see that the current in the parallel configuration is greater than in the series configuration:
therefore, the correct answer is false.
Answer:
Explanation:
According to Newton's Second Law of Motion, force is the product of mass and acceleration.
The mass of the wagon is 12 kilograms and the acceleration is 3 meters per square second.
Substitute the values into the formula.
Multiply.
- 1 kilogram meter per square second ( 1 kg*m/s²) is equal to 1 Newton (N)
- Our answer of 36 kg*m/s² is equal to 36 N
The force required for the 12 kilogram wagon to accelerate at 3 meters per square second is <u>36 Newtons.</u>
