Answer:
For an excellent understanding of the system, we must first consider that everything that all the objects within it are at rest, which implies directly that the initial moment is zero.
From this it is logical to intuit that when applying an external force on the system, the speed of the system will be generated to change.
Thus applying the law of conservation, we understand that
Initial System Moment = Final System Moment.
From this we conclude that the final moment is 0.
Momentum = 0kg-m / s
Answer:
friction coefficient on the rough road is 0.117
Explanation:
As we know that car is taking turn on flat rough road
So here we can say that required centripetal force for circular motion of car is due to frictional force
So we have
now we have
so we have
In astronomy, the geocentric model is a model that depicts the Earth at the center of the Universe, with the Sun and the other planets revolving around it.
Therefore, the correct answer is
<span>"All objects in the universe revolve around Earth. "
</span>which corresponds to the geocentric model.
By elasticity, the most nearly load is D. 12370 N .
We need to know about elasticity to solve this problem. In elasticity, stress can be determined as
σ = e . δ
where σ is stress, e is elastic modulus and δ is the strain
From the question above, we know that:
e = 70 GPa = 70 x 10⁹ Pa
d = 15 mm = 0.015 m
δ = 0.001 mm/mm
Find the stress
σ = e . δ
σ = 70 x 10⁹ . 0.001
σ = 7 x 10⁷ Pa
Find the surface area of the aluminum rod
A = πR²
A = π(0.015/2)²
A = 1.77 x 10¯⁴ m²
Find the load
F / A = σ
F = σ x A
F = 7 x 10⁷ x 1.77 x 10¯⁴
F = 12375 N
