Answer:
The force is
Explanation:
From the question we are told that
The tangential resistive force is
The mass of the wheel is m = 1.80 kg
The diameter of the wheel is
The diameter of the sprocket is
The angular acceleration considered is
Generally the radius of the wheel is
=>
=>
Generally the radius of the sprocket is
=>
=>
Generally the moment of inertia of the wheel is mathematically represented as
=>
=>
Generally the torque experienced by the wheel due to the forces acting on it is mathematically represented as
Here is the force acting on the sprocket
So
Generally the torques that will cause the wheel to move with is mathematically represented as
So

Answer:
496.7 K
Explanation:
The efficiency of a Carnot engine is given by the equation:
where:
is the temperature of the hot reservoir
is the temperature of the cold reservoir
For the engine in the problem, we know that
is the efficiency
is the temperature of the cold reservoir
Solving for , we find:
A very small portion of the electromagnetic spectrum is visible
to the human eye.
It's kind of hard to talk about real numbers, since the electromagnetic
spectrum has no ends. But if you consider the spectrum to be the
range of frequencies between household electrical power and gamma
rays, you get a range of roughly 50 octaves, of which our eyes are able
to detect about one octave.
Answer:
option (d)
Explanation:
The minimum angle of inclination of the inclined plane from the horizontal such that the object placed on the inclined plane is just start sliding down.
The value of angle of repose is given by the
tan θ = μ
Where, θ be the angle between the horizontal plane and the inclined plane and μ be the coefficient of friction.
It is also called as the angle of sliding.
