The magnitude of the E-field decreases as the square of the distance from the charge, just like gravity.
Location ' x ' is √(2² + 3²) = √13 m from the charge.
Location ' y ' is √ [ (-3)² + (-2)² ] = √13 m from the charge.
The magnitude of the E-field is the same at both locations.
The direction is also the same at both locations ... it points toward the origin.
The kinetic energy of toast is 0.06 J.
<u>Explanation:</u>
Kinetic energy is the way to determine the energy released when an object is in motion. In other times, it can be the energy required to move any object and to make it in motion.
As the mass of the toast is given as 8 g and speed is given as 15 m/s, if we ignore the friction caused by air molecules. Then the kinetic energy is the product of mass and square of velocity.
K.E. = × mass × v²
Kinetic energy =
Since, the weight is given in grams , it needed to be converted into kg.
Kinetic energy = 0.06 J
Thus, the kinetic energy of toast is 0.06 J.
Hypothesis testing is basically testing the results of a experiment to see weather your results are valid or not.
