Answer:
Explanation:
If the stone will reach the top position of flag pole at t = 0.5 s and t = 4.1 s
so here the total time of the motion above the top point of pole is given as
now we have
so this is the speed at the top of flag pole
now we have
now the height of flag pole is given as
<u>Answer :</u>
correct choice is option A
Motors convert electrical energy into mechanical energy. Generators convert mechanical energy into electrical energy.
Explanation :
Their difference is described as;
Premise MOTOR
- The Motor Converts Electrical imperatives into vitality .
- It uses control. (power)
- In partner degree motor this is to be given to the curl winding
- The Shaft of the motor is driven by the drawing in power made among loop and field.
- Engine seeks after Fleming's left guideline.
GENERATOR
- Generator changes over Mechanical essentialness to Electrical imperatives .
- It produces control (electricity)
- In the generator current is conveyed inside the curl winding.
- The Shaft is associated with the rotor and is driven by mechanical power.
- Generator seeks after Fleming's correct guideline. .
The angular speed of the merry-go-round is
ω = 0.10 rad/s
The angular moment of inertia of a mass, m, at a radius, r, from the center of the wheel is
I = mr²
Therefore, the angular moment of inertia for the children are
I₁ = (25 kg)*(1.0 m)² = 25 kg-m²
I₂ = (25 kg)*(1.5 m)² = 56.25 kg-m²
The combined angular momentum is
ω(I₁ + I₂) = (0.10 rad/s)*(25 + 56.25 kg-m²)
= 8.125 (kg-m²)/s
Answer: 8.125 (kg-m²)/s
Answer:
No, some energy will be dissipated energy due to work of air resistance.
Answer:absorbs and emits electromagnetic radiation at all wavelengths
Explanation:
A blackbody is a believed to be a perfect absorber and reflector of radiation. Blackbody, in physics, refers to a surface that absorbs all radiant energy that falls on it. It is supposed that because incident visible light will be absorbed rather than reflected, the surface will appear black.
