Answer:
B. nuclear fusion
Explanation:
Atomic fusion is a process in which two or more lighter nuclei combine to form a heavier nucleus.
The mass of the single nucleus thus formed is lighter than the initial mass.
There is a difference in mass in the heavier nucleus thus formed. According to Einstein's mass-energy equation, the change in mass is equated towards energy.
The energy liberated in the process is called as thermo-nuclear energy.
As in the case of isotopes of hydrogen fuses to form helium, the nuclear reaction is given by relation
₁H³ + ₁H² → ₂He⁴ + ₀n¹ + energy
Thus, the nuclear reaction of hydrogen isotopes forming helium is nuclear fusion.
Answer: B
Explanation:
The vertical component of a vector such as velocity is the magnitude of the vector multiplied by the sine of the angle.
The "resolution" lowers. This is caused because most optical microscopes bend light. The more light there is, the more it bends. This causes the edges of the object to be blurred, and possibly even blot out the object.
Velocity =2 pie*r/t
distance = 2 (pie) r
accelaretion =distance/t2
f=m*v2/r
v=square root of Fr/m
Answer:
E = 600 J
Explanation:
The power is
P = W / t = E / t
E = P t
The electrical power is
P = V I
We substitute
E = V I t
Let's calculate
E = 12 50 1
E = 600 J
This is the energy stored in the battery
