Answer:
The number of available energy is 
Explanation:
Given that,
Energy 
Temperature = 2.7 K
Energy states per unit volume 
We need to calculate the number of available energy
Using formula of energy
Where, h = Planck constant
c = speed of light
E = energy
Put the value into the formula
Hence, The number of available energy is
Answer:
C
Explanation:
The electric field inside a conductor is always zero if the charges inside the conductor are not moving.
Since the electron are not moving then they must be in electrostatic equilibrium which means the electric field inside the conductor is zero. if the electric field existed inside the conductor then there will be net force on all the electrons and the electrons will accelerate.
A) it occurs when earth is between the sun and the moon
continents, paleoclimate indicators, truncated geologic features, and fossils:D
Answer:
Point A
Explanation:
The work done by stretching or compressing a spring is given by E=1/2kx²
The potential energy is numerically equal to the work done.
This means that the higher the bigger the value of the extension, x, the higher the energy contained.
In this scenario the modulus of x is considered.
Among the given values of x the modulus of -5 is the largest.
thus it gives the highest value of energy.
