<span>The correct answer is: Positive compared to
Explanation:
An action potential is the process that happens when a neuron fires a signal. During the action potential, part of the neural membrane opens to allow positively charged ions inside the cell and negatively charged ions out; consequently, the positive charge inside the neuron increases during that process. In a nutshell, during an action potential, the electrical charge inside the neuron is positive compared to the electrical charge outside the neuron.</span>
Answer:
Control rods are an important technology for maintaining the desired state of fission reactions within a nuclear reactor. They constitute a real-time control of the fission process, which is crucial for both keeping the fission chain reaction active and preventing it from accelerating beyond control.

Answer : The correct option is, X : radius and Y : tangential speed
Explanation :
Centripetal force : It is defined as a force which acts on the object to keep the object moving along a circular path.
Formula for centripetal force :
where,
= centripetal force
m = mass
r = radius
V = tangential speed
The quantity belong in cell X is radius and in the cell Y is tangential speed
Hence, the correct option is, X : radius and Y : tangential speed
Answer:
T = 50 + 80e^(-0.2t)
Explanation:
Newton's law of cooling says the rate of change of temperature with respect to time is proportional to the temperature difference:
dT/dt = k (T − Tₐ)
Separating the variables and integrating:
dT / (T − Tₐ) = k dt
ln (T − Tₐ) = kt + C
T − Tₐ = Ce^(kt)
T = Tₐ + Ce^(kt)
Given that Tₐ = 50 and k = -0.2:
T = 50 + Ce^(-0.2t)
At t = 0, T = 130.
130 = 50 + Ce^(0)
130 = 50 + C
C = 80
Therefore:
T = 50 + 80e^(-0.2t)
