1.Net Energy Gain is a concept used in energy economics that refers to the difference between the energy expended to harvest an energy source and the amount of energy gained from that harvest.
The correct answer is: The speed of sound is faster in the water than in the air.
The speed of sound is different between those two mediums because they have different densities. Since, water is denser than air, more energy is required to generate a wave but once it stars, it travels faster than it would do in air. Sound waves’ travel can be presented by particles that transmit the energy one to another as they bump. The sound speed is lower in the air (than in water) because particles are far apart, so they travel further before they collide.
Answer: All of them seem to apply.
Explanation:
A., Its important to know if your car that is being collided is a small car or big truck, as they will end up effecting who gets hurt the most.
B., Same thing as A. but with the other vehicle.
C., The velocity matters a lot with a collision, since a slow crash won't have as much damage as a car going fast and hitting someone. Also it won't be as likely to be fatal if the car crashing into you is going slow.
D., This is the only one I'm not too sure on, but it seems like how fast the car can accelerate once collided with would be a big factor on whether it would come to a halt or skid across the road.
I believe the answer is chromosomes.
Chromosomes are basically coiled up pieces of DNA with proteins.
I hope this helps! If it doesn't, please reply.
Both chicken pox and shingles are caused by varicella zoster.
Explanation:
Shingles and chicken pox both occurs by the attack of the virus, varicella zoster.
Cause: - The chicken pox spreads through the infectious elements in a person’s cough, sneeze and breathing. The shingles occur when this virus gets reactivated.
Portal entry: - Chicken pox virus enters through the tract of respiration and shingles enter from a person who already have it.
Signs & Symptoms: - Pox includes- fever, blister like itchy rash and shingles include- blister rash which has a distribution that is like a band.
Incubation period: - Pox can stay for a minimum of 15 days approximately and shingles too last for few weeks.
Treatment and prevention: - Both include treatment of antiviral and both can be prevented by avoiding infected people and increasing body immunity etc.
