Answer:
change in the angular momentum gives a greater change in the kinetic energy since it has a quadratic dependence with the angular velocity
Explanation:
Let's write the definition of angular momentum
L = I w
the kinetic energy is
K = ½ I w²
w = L / I
we substitute
K = ½ I L² / I²
K = L² / 2I
K / L = w / 2
therefore a change in the angular momentum gives a greater change in the kinetic energy since it has a quadratic dependence with the angular velocity
Answer:75 percent
Explanation:so in order tro fin d thge efficiency i used the forumla ,efficency=useful output energy/input energyx100%,in order to use this formula i needed the output,which i found by subtracting the input energy with wasted energy,that gave me the output,and after founding the output,i put that into the formula,
output energy=input energy - wasted energy
output energy=6000j-1500j
output energy=4500
put that into the formula
efficiency =output energy/input enrgy x100%
efficiency=4500/6000 multiplied by 100%
efficiency=0.75x100%
efficiency=75%

<h3><u>Answer</u> :</h3>
◈ As per newton's second law of motion, Force is defined as the product of mass and acceleration
Mathematically,
Unit of mass : kg
Unit of acceleration : m/s²
Therefore,
Unit of force ➠ <u>kg m/s²</u>
SI unit : <u>N (newton)</u> or <u>kg m/s²</u>
