Answer:
Explanation:
Given that,
Mass of the thin hoop
M = 2kg
Radius of the hoop
R = 0.6m
Moment of inertial of a hoop is
I = MR²
I = 2 × 0.6²
I = 0.72 kgm²
Period of a physical pendulum of small amplitude is given by
T = 2π √(I / Mgd)
Where,
T is the period in seconds
I is the moment of inertia in kgm²
I = 0.72 kgm²
M is the mass of the hoop
M = 2kg
g is the acceleration due to gravity
g = 9.8m/s²
d is the distance from rotational axis to center of of gravity
Therefore, d = r = 0.6m
Then, applying the formula
T = 2π √ (I / MgR)
T = 2π √ (0.72 / (2 × 9.8× 0.6)
T = 2π √ ( 0.72 / 11.76)
T = 2π √0.06122
T = 2π × 0.2474
T = 1.5547 seconds
T ≈ 1.55 seconds to 2d•p
Then, the period of oscillation is 1.55seconds
Constantine I helped to socially and politically unify the early byzantine empire by tolerating and even promoting christianity.
Answer:
Toll like receptors
Explanation:
They are proteins and produce the required signals in the innate immune system. They help in identifying the molecular structure and composition of pathogens.The signals they give results in inflammatory response.
Answer:
The correct answer is certainly true.
Explanation:
You first need to fully understand the conflict/problem before explaining it.
Most students do this when doing a research project.
For example: Let's say I had a project to explain solutions for climate change but I didn't even know what it is and how it was caused. Well of course your teacher will make you research the topic in order to represent it correctly.
