Answer:
The temperature of the core raises by every second.
Explanation:
Since the average specific heat of the reactor core is 0.3349 kJ/kgC
It means that we require 0.3349 kJ of heat to raise the temperature of 1 kg of core material by 1 degree Celsius
Thus reactor core whose mass is will require
energy to raise it's temperature by 1 degree Celsius in 1 second
Hence by the concept of proportionately we can infer 150 MW of power will increase the temperature by
Here is the correct question
A constant electric field E = 100 N/C pointing along the positive x-axis is present throughout a region of space that includes the plane bounded by the y and z axes and the lines y = 50 cm and z = 50 cm. The electric flux through the plane's surface, in N ⋅ m 2/C, is
Answer:
25 Nm²/C
Explanation:
given that
The constant electrical field E = 100 N/C
the field lines y and z = 50 cm and 50 cm respectively
= 0.5 m and 0.5 m
For constant electric field, the flux = electric field x area through which field lines are passing
i.e Flux = (100 ×0.5 × 0.5) Nm²/C
= 25 Nm²/C
Therefore; The electric flux through the plane's surface, in Nm²/C is = 25 Nm²/C
Answer:
When the different ions cross the neuron membrane due to this an action potential generated
Explanation:
When the different ions cross the neuron membrane due to this an action potential generated.
The steps for action potential
1. Depolarization .When positively charge sodium ions enters in to the nerve cell.This is also known as upswing.
2. Repolarization
3. Refractory Phase
So the answer is "When the different ions cross the neuron membrane".
The best answer between the two options would be the second choice B) FALSE.
Answer:
25N.s=25kgm/s
Explanation:
The resulting momentum in this case is equal to the impulse created by the force 5N during 5 seconds
ΔP=Force.time=F.t
= 5x5=25kgm/s
