Answer:

The false statement is 'Electric field lines form closed loops'.

Explanation:

  • Electric field lines originate from positive end and terminates at negative end,i.e., field lines are inward in direction to the negative charges and outward from the positive charges.
  • These lines when close together represents high intensity and when far apart shows low intensity of the field.
  • These lines do not intersect, as the tangent drawn on these lines provides us with the field direction and intersection of these lines means two field directions which is not possible.
  • These lines unlike magnetic field lines do not form closed loops as they do not turn around but originate at positive end and terminates at negative end which ensures no loop formation.

A toaster oven uses 65,000 joules of energy in 40sec to toast a piece of bread. What is the power of the oven?
storchak [24]

Answer:

Power = 1625 Watts

Explanation:

Given the following data;

Energy = 65,000 J

Time = 40secs

To find the power;

Power can be defined as the energy required to do work per unit time.

Mathematically, it is given by the formula;

Power = \frac {Energy}{time}

Substituting into the equation, we have

Power = 65,000/40

Power = 1625 Watts
