Answer:
A semiconductor acts like an ideal insulator at absolute zero temperature that is at zero kelvin. It is because the free electrons in the valence band of semiconductors will not carry enough thermal energy to overcome the forbidden energy gap at absolute zero.
Answer:
F = M a is a vector equation
F has the same sign as A and is in the same direction as the vector a
If a is positive then F must also be positive
Answer:
is not this one Planet B is expected to be hotter than Planet A.
Explanation:
Answer:
2.74 × 10^33 J
Explanation:
the formula to calculate kinetic energy is:
1/2mv²
m= mass (kg)
v= velocity (m/s)
given that,
m = 5.97 × 10^24
v = 30.29 km s-1
= 30290 m s-1
1/2× 5.97 × 10^24 × 30290²
=2.74 × 10^33 J
