Answer:
Explanation:
given,
mass of wheel(M) = 3 Kg
radius(r) = 35 cm
revolution (ω_i)= 800 rev/s
mass (m)= 1.1 Kg
I_{wheel} = Mr²
when mass attached at the edge
I' = Mr² + mr²
using conservation of angular momentum
Answer:
They developed a test for poisons in the human tissues
Explanation:
Around the 19th century, Mathieu Orfila and Robert Christison developed important tests that identified poisons in human tissues.
By so doing, they laid the foundation for what is now called forensic toxicology. This science attempts to identify poisons in human tissues especially by way of autopsies and forensic investigation.
Today forensic toxicology has expanded to include alcohol testing techniques as well as testing athletes for intake of performance enhancing substances.
Answer:
4.662 slugs
Explanation:
Your mass on the moon should always be the same as any planet you are on (due to law of mass conservation), only your weight be different as gravitational acceleration is different on each planet.
If you weight 150 lbf on Earth, and gravitational acceleration on Earth is 32.174 ft/s2. The your mass on Earth is
m = W / g = 150 / 32.174 = 4.662 slugs
which is also your mass on the moon.
<span>All of these are directly proportional to each other, meaning that if one goes up or down, they all do the same.
So if the temperature increases so does the heat. If the heat increases then so does the thermal energy. If the temperature goes up then so does the thermal energy. ETC...</span>
(And don't forget that an object going around a curve at a constant speed is also accelerating.)
I believe there are two reasons:
1). The term is inadequately taught in the American public school system ... along with much of the rest of Science and Math in general.
2). The word became permanently and indelibly corrupted when the automotive industry decided to name the gas pedal the "accelerator".
