Answer:
True
Explanation:
Diffusion is an active process that requires a cell to expand a great deal of energy. ... Diffusion through ion channels is a form of active transport. False. Passive transport uses ATP to move molecules against their concentration gradient.
Answer:
5106.38 Ω
Explanation:
From the question given above, the following data were obtained:
Current (I) = 0.0235 A
Voltage (V) = 120 V
Resistor (R) =?
From ohm's law,
V = IR
Where:
V => is the voltage.
I => is the current
R => is the resistor
With the above formula, we can obtain the size of the resistor needed as follow:
Current (I) = 0.0235 A
Voltage (V) = 120 V
Resistor (R) =?
V = IR
120 = 0.0235 × R
Divide both side by 0.0235
R = 120 / 0.0235
R = 5106.38 Ω
Thus, the size of the resistor needed is 5106.38 Ω
The answer is a throw the ball with greater force
Answer:
Explanation:
Hello!
In this case, since the Gibbs free energy of any process is related with the enthalpy change, temperature and entropy change as shown below:
For a chemical reaction it is simply modified to:
Thus, since the enthalpy of reaction is given as -304.2 kJ and the entropy as -414.2 J/K (-0.4142 kJ/K), at 775 K the Gibbs free energy of reaction turns out:
Whose result means this is a nonspontaneous reaction.
Best regards!
