The work done to accelerate the acrobat is given by
where F is the force applied and d the distance of application of the force.
If the barrel is 3.05 m long, then d=3.05 m. Therefore we can find the force:
Answer:
Sorry, I don't understand this language, sorry dear
Answer:
Make the angle of reflection and the angle of incidence equal.
Explanation:
The law of reflection states that at the point of incidence on a smooth surface, the angle of incidence is equal to the angle of reflection, The incident ray, the normal and the reflected ray lie on the same plane.
All liquids become solid, above the melting point!!! Hope this helps!!!
The power developed by the electric motor is 6000 Watts
<h3>Definition of power </h3>
Power is defined as the rate at which work is done. Mathematically, it is expressed as
Power = Work / time
But
Work = mass (m) × acceleration due to gravity (g) × height (h)
Work = mgh
Therefore,
Power = mgh / t
With the above formula, we can obtain the power developed by the motor.
<h3>How to determine the power </h3>
- Mass (m) = 200 Kg
- Height (h) = 6 m
- Acceleration due to gravity (g) = 10 m/s²
- Time (t) = 2 s
- Power =?
Power = mgh / t
Power = (200 × 10 × 6) / 2
Power = 12000 / 2
Power = 6000 Watts
