How do fission nuclear reactions differ from fusion nuclear reactions?

A. Fission reactions involve the conversion of matter into energy, but fusion reactions do not.

B. Fusion reactions involve the conversion of matter into energy, but fission reactions do not.

C. Fission reactions are used to generate electricity for consumers, but fusion reactions are not.

D. Fusion reactions are used to generate electricity for consumers, but fission reactions are not.

Answer:

Explanation:

Both fission and fusion are nuclear reactions that produce energy, but their applications differs.

Fission is the splitting of a large (heavy, unstable) nucleus into smaller ones, and fusion is the process where nuclei of small atoms are combine together to form the nuclei of larger atoms releasing vast amounts of energy.

The correct answer is c. Fission reactions are used to generate electricity for consumers, but fusion reactions are not.

The physics of fusion is the process that makes the sun shine, and that makes the hydrogen bomb explode.

What energy is a wind turbine transferring>?????????????????????????????????????

Answers

The wind-mill is taking kinetic energy out of the moving air that spins it, and uses that energy to do things. It may pump water up out of the ground, it may turn a big stone to grind wheat, or it may turn an electric generator to turn the energy it collects into electrical energy.

in 1994, Vladimir Kurlivich , from Belarus, set the world record as the world's strongest weight lifter. he did this by lifting and holding above his head a barbell whise mass was 253kg. Kurlovich's mass at the time was 133 kg. caculate the normal force exerted on each of his feet during the time he. was having ldi g the barbell

Answers

The free-body diagram of your question is; 2 downward forces (253 kg mass of barbell & 133 kg body mass of Kurlovich) acting together on a point supported by 2 upward forces as normal forces exerted by Kurlovich's feet.

Solving the normal forces exerted by 2 feet :

Summation of Forces Vertical = 0

2 Dowwnard Forces = 2 Upward Forces (2F)

253 + 133 = 2F

2F = 386 Kgs

F = 386 / 2

F = 193 Kgs (Normal Force Exerted by Each Foot)

Final answer:

To calculate the normal force exerted on each of Vladimir Kurlovich's feet while lifting the barbell, we need to consider the weights of Kurlovich and the barbell. The normal force is equal to the sum of the two weights.

Explanation:

To calculate the normal force exerted on each of Vladimir Kurlovich's feet while lifting the barbell, we need to consider the weight of Kurlovich and the weight of the barbell. The normal force is equal to the sum of Kurlovich's weight and the weight of the barbell, as it balances the gravitational force pulling them downwards. Kurlovich's weight can be calculated using his mass and the acceleration due to gravity, which is approximately 9.8 m/s².

Step 1:

Calculate Kurlovich's weight:
Mass = 133 kg
Acceleration due to gravity = 9.8 m/s²
Weight = Mass × Acceleration due to gravity
Weight = 133 kg × 9.8 m/s²

Step 2:

Calculate the weight of the barbell:
Mass = 253 kg
Acceleration due to gravity = 9.8 m/s²
Weight = Mass × Acceleration due to gravity
Weight = 253 kg × 9.8 m/s²

Step 3:

Calculate the normal force exerted on each foot:
Normal force = Kurlovich's weight + Barbell's weight

Why does the sun change colors at sunset

Answers

The reason that the sun changes colors at sunset is because small particles and molecules in the atmosphere change the direction of light ray causing them to scatter and resulting in a beautiful sunset.
