That's called the "red shift" of the star's spectrum, because red is the lowest frequency/longest wavelength in visible light.
Answer:
Explanation:
From the given information, we are to compare the minimum energies required to remove a neutron from 
, 
and 
To start with ; the minimum energy required to remove a neutron from is :
= 
= (38156.36 - 37225.15 -939.57) MeV
= -8.36 MeV Since energy is being given out
Thus, E = 8.36 MeV
the minimum energy required to remove a neutron from is :
= 
= ( 39084.46 - 38156.36 - 939.57) MeV
= -11.47 MeV Since energy is being given out
Thus, E = 11.47 MeV
the minimum energy required to remove a neutron from is :
= 
= (40016.10 -39084.46 -939.57) MeV
= - 7.93 MeV Since energy is being given out
Thus, E =7.93 MeV
Why there is a distinct increase of this energy for ?
This is as a result of electronic configuration of which posses the same number of proton and neutron, as such, tends to acquire more stability. For this reason, it will be difficult to remove a neutron from .
Answer:
here friction must be reduced when
B.) the axle of your car wheels while you are driving
Explanation:
Friction is a type of force which is required in many process and in those if we reduce the friction then the system may not work
So here we know that
A.) moving your mouse along the mousepad
Here we know that the mousepad is working when mouse runs on the pad and if it makes frictionless than it will not work
B.) the axle of your car wheels while you are driving
Here we must have to reduce the friction because here if motion of axle is smooth then it will have less energy loss
C.) you are climbing a steep ladder
While climbing on the steep ladder we must require large friction for balancing
D.) the surface of a park bench while you sitting on it
While sitting on the bench we require friction for our static equilibrium
so here friction must be reduced when
B.) the axle of your car wheels while you are driving
