Answer:
0.0107
Explanation:
We know that
The rotational kinetic energy due to four wheel is
1/2ဃ²I x 4
So
1/4mR²(v/R)² = mv²
But kinetic energy along straight path of the car is 1/2mv²
=> 1/2( 817)v ²
Kc= 408.5v²
So The fraction of total kinetic energy that is due to rotation of the wheel about their axis
Is Kw/Kw+Kc
and Kw = 1/2* 8.91v²= 4.45v²
So 4.45v²/ 4.45v²+ 408.5v²
= 0.0107 as fraction of total kinetic energy
Complete question:
A 0.50 kilogram frog is at rest on the bank surrounding a pond of water. As the frog leaps from the bank, the magnitude of the acceleration of the frog is 4.0 meters per second^2. Calculate The magnitude of the net force exerted on the frog as it leaps.
Answer:
2.0N
Explanation:
Given that,
Mass, m of the frog = 0.5 kg
The acceleration of the frog = 4.0 m/s².
We have been asked To find,
The magnitude of the net force exerted on the frog as it leaps.
So
We calculate this using the formula below :
F = ma
When we insert the values into the formula, we have:
F = 0.5 kg × 4 m/s²
F = 2.0 N
Therefore, the magnitude of net force is 2.0 N.
Answer:
B. interactive
Explanation:
newtons first law is inertia his second is acceleration and third is interactive.
The organism shown above belongs to "the animal kingdom".
<u>Answer:</u> Option C
<u>Explanation:</u>
The biological classification's hierarchy involves eight important taxonomic ranks. They are written below in decreasing order: Life > Domain > Kingdom > Phylum > Class > Order > Family > Genus > Species.
The U.S and Canada have historically used a six-kingdom scheme in their traditional textbook, such as Plantae, Animalia, Protista, Fungi, Archaea / Archaebacteria, and Bacteria / Eubacteria. The given image depicts snake which come under "Animalia Kingdom", carnivorous reptiles to suborder Serpentes.
