The Answer is B) Office of Human Services Emergency Preparedness and Response
Answer:
Hemoglobin bound to oxygen absorbs blue-green light, which means that it reflects red-orange light into our eyes, appearing red. That's why blood turns bright cherry red when oxygen binds to its iron. Without oxygen connected, blood is a darker red color.
Hope this helps :)
Nuclear fusion is taking two atoms and combining them in to one atom, while nuclear fission takes one atom and splits it into two atoms.
Answer:
Moment of the 4N force = 16Nm
Moment of the 6N force = 12Nm
Explanation:
Find the diagram attached.
Moment of a force is the product of the force and the perpendicular distance from the point of application
For the 4N force
Distance of the force from O is 4m
Moment of the 4N force = 4N * 4m
Moment of the 4N force = 16Nm
For the 6N force
Distance of the force from O is 2m
Moment of the 6N force = 6N * 2m
Moment of the 6N force = 12Nm
Answer:
Explanation:
When 2 gms of steam condenses to water at 100 degree latent heat of vaporization is releases which is calculated as follows
Heat released = mass x latent heat of vaporization
= 2 x 2260 = 4520 J
When 2 gms of water at 100 degree is cooled to ice water at zero degree heat is releases which is calculated as follows
Heat released = mass x specific heat x( 100-0)
= 2 x 4.2 x 100 = 840 J
When 2 gms of water at zero degree condenses to ice at zero degree latent heat of fusion is releases which is calculated as follows
Heat released = mass x latent heat of fusion
= 2 x 334 = 668 J
When 2 grams of steam at 100 degrees Celsius turns to ice at 0 degrees Celsius heat released will be sum of all the heat released as mentioned above ie
4520 + 840 +668 = 6028 J
