Answer:
The speed is the same at 1.5 m/s while
The work done by the force F is 0.4335 J
Explanation:
Here we have angular acceleration α = v²/r
Force = ma = 2.8 × 1.5²/r₁
and ω₁ = v₁/r₁ = ω₂ = v₁/r₂
The distance moved by the force = 600 - 300 = 300 mm = 0.3 m
If the velocity is constant
The speed is 1.5 m/s while the work done is
2.8 × 1.5²1/(effective radius) ×0.3
r₁ = effective radius
2.8*9.81 = 2.8 × 1.5²/r₁
r₁ = 0.229
The work done by the force = 2.8 × 1.5²*1/r₁ *0.3 = 0.4335 J
Answer:
Option (C)
Explanation:
A tool is usually defined as an equipment or a device that is hold by the hands and is used to carry out a particular function. For example, a hammer is a tool that is used to hit on a hard surface.
A tool can be considered as a technology under a certain condition, such as the applications of this objects are helpful in solving a practical problem, with ease and comfortability.
Thus, the correct answer is option (C).
