Answer:
The power of the bulb is reduced to a quarter
Explanation:
The power in an electrical circuit is
P = V I = I² R
If the dimmer cuts the current in half
I = I₀ / 2
The resistance of the light bulb after hot is little affected by small changes in the current
We substitute in the equation
P = I₂ R
P = (I₀ /2)² R
P = ¼ I₀² R
P = ¼ P₀
The power of the bulb is reduced to a quarter
Answer:
Torque = 1191.68 N-m
Explanation:
Given data
mass m = 76 kg
standingdistance r = 1.6 m
Solution
we get here torque that si express as
torque = force × distance ................1
torque = r × F sin(theta)
and we know that
F = mg .........2
and g = 9.8 m/s²
put here value in equation 1 we get
Torque = 76 × 1.6 × 9.8 × sin(90)
Torque = 1191.68 N-m

Answer: Option (c) is the correct answer.
Explanation:
When two or more small nuclei combine together to form a larger nuclei then this process is known as nuclear reaction.
The smaller is an atom, the more energy it requires to release an electron. This energy is known as binding energy.
Thus, when two small nuclei fuse together then there will be more binding energy as compared to when two large nuclei fuse together.
For example, fusion of two hydrogen atoms release more energy then one helium atom, and upon binding excess energy is released into the space.
Hence, we can conclude that energy is released in a nuclear fusion reaction based on mass-energy equivalence because for small nuclei, the binding energy of the lighter nuclei is greater than the binding energy of the heavier nucleus.
