Explanation:
I have watched "Sherlock Holmes". It is a story chain of various deeds of a British detective. He uses his senses with full confidence in order to solve various puzzles. He uses detailed observation of any incident or any character.
He collects information from his logic and creates his own story which seems to be fit in given circumstances. He uses deductive reasoning in order to reach to a conclusion. There are various scenes in this whole series where he can tell the whole schedule of a person just simply observing his/her coat.
I remember a scene in which a person comes to him. He just looks at him for few seconds. Sherlock notices tea stain on his coat. In the very next minute, Sherlock asks him, how bad was his morning? The person gets confused and surprised also.
He asks the reason behind Sherlock's question. Sherlock tells him a story based on his deductive reasoning. He tells him about the noticing of tea stain. He also explains size and configuration of that stain. He also elaborates that such dimensions can be obtained only in a fast moving object when someone has fight at the same time.
He also tells him some other details. All these were based on his extreme senses and his detailed perceptions about the circumstances. Sherlock considers his perceptions as real and tests them according to his knowledge and logical reasoning. He mixes all these things with his deductive reasoning which provides him a meaningful story.
Answer:
<em>0.981 rad/sec^2</em>
<em></em>
Explanation:
mass that pulls on string = 5 kg
weight due to mass = 5 x 9.81 = 49.05 N
radius of rod = 0.1 m
torque produced by this force on the rod = force x radius
torque = 49.05 x 0.1 = 4.905 N-m
mass of disk = 125 kg
radius of disk = 0.2 m
moment of inertia of the disk I = m
I = 125 x = 5 kg-m^2
from the equation, <em>T = Iα</em>
where T is torque
I is moment of inertia
α is angular acceleration
imputing values,
4.905 = 5α
α = 4.905/5 = <em>0.981 rad/sec^2</em>
Answer:
true
Explanation:
Initially it requires more force to break the interlock between the irregularities of two surfaces. But once the block is in motion, it takes time to interlock between the irregularities of two surfaces. Also, the body gains the inertia of motion.
Answer:
A. T₁ = 7.204 N
B. T₂ = 19.07 N
C. I = 0.011979 kg * m²
Explanation:
Given
m₁ = 2.02 kg , d = 0.120 m, m₂ = 3.06 kg, s = 1.17 m, t = 0.810s
The tension can be find using the conserved energy in each axis so:
∑Fₓ = T₁ = m₁ * a₁
∑Fy = m₂ * g - T₂ = m₂ * a₁
Now to find the acceleration can use the equation of Newton motion
s = v₁* t + ¹/₂ * a₁ * t ²
Solve to a'
a₁ = 2* s / t ² = 2 * 1.17 m / (0.810 s)²
a₁ = 3.566 m/s²
A).
T₁ = m₁ * a₁ = T₁ = 2.02 kg * 3.566 m/s²
T₁ = 7.204 N
B).
T₂ = m₂ *(g - a₁) = 3.06 kg *(9.8 - 3.566) m/s²
T₂ = 19.07 N
C).
Finally to find the moment of inertia use the equation
∑ T = (T₂ - T₁) * r = I * α
α = a₁ / r
I = (T₂ - T₁ )* r²/ a₁
I = ( 19.07 - 7.204)* (0.06 m)² / 3.566 m/s²
I = 0.011979 kg * m²
Answer:304 kg*ms or in ms 84.48 kgm/s
