If the amount of electrical energy is 50 Joules before the conversions, then it would be 50 Joules after the conversion.
According to law of conservation of energy, we cannot create or destroy energy so it remains constant
Hope this helps!
Answer:cart B
Explanation:
For cart A speed is constant therefore there is no acceleration because acceleration is rate of change of velocity
thus there is no net force
For cart B there is change in velocity in the left direction , so there is net acceleration towards left
so there is net force in the left direction
For cart C there is decrease in velocity i.e. negative acceleration or deceleration . Therefore there is a net force towards right which opposes the motion
<span>Letter
C has the correct illustration. Two objects with the same charge (in this case,
both are positively charged) will repel each other. </span>
Letter
A is incorrect because a positive charged object will attract a negatively
charged object.
Letter
B is incorrect because both of them are negatively charged, which means they
should be repelling each other.
The balanced formula is B.
