Given that,
Electrical energy of the motor = 2280 J
Kinetic energy = 1606 J
Wasted energy in thermal and sound energy = 550 J
To find,
The efficiency of the motor in percent.
Solution,
Efficiency is defined as the ratio of useful output energy to the total energy.
Total energy = 2280 J
Useful energy = 1606 J
So, the efficiency of the motor is 70.43%.
Solubility is how much solute will dissolve into a solvent. A
Is Newton runs at the same average speed then the answer would be 40/5.79 = 6.908 m/s
Light rays travel parallel to each other, no image formed
Answer:
The density of iceberg upper water and under water are 102.5 kg/m³ and 922.5 kg/m³
Explanation:
Given that,
Volume of seawater = 90 % of Volume of iceberg
Volume of visible surface = 10 %
Density of seawater = 1025 kg/m³
We need to calculate the density of the iceberg
Using equilibrium condition
Put the value into the formula
