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%.
here force between two particles is given by Coulomb's law where two particles will either repel or attract each other
this force of attraction or repulsion is given by the equation
here we know that
= two point charges
r = distance between two charges
so now we will substitute all values in it
so above is the force between two point charges
The correct answer is A and C
During a Spring Tide, it will be horizontal, and a Neap tide is vertical
