The answer is differentiation. Differentiation is worried about things like rates and increasing velocities, slants and bends ect. Differentiation finds the immediate rate of progress of a capacity as for an autonomous variable. It is utilized when an amount demonstrates non-Linear variety. You can discover the speed of a molecule at a specific time by knowing the separation as an element of time.
Work done = fore × distance
wd= 47N ×o.25m
wd= 12.22Nm
The greater the distance over which a force is applied, the greater the work done.
Answer:
A. Both sources are positively charged.
Explanation:
Before answering, let's remind what is the direction of the electric field lines for a positive charge and a negative charge. Keeping in mind that the direction of the field lines is given by the direction of motion of a positive test charged place in that electric field, we have:
- For a positive charge, field lines point away from the charge (because a positive test charge will move away from the source of the field)
- For a negative charge, field lines point towards the charge (because a negative test charged will move towards the source of the field)
In this example, we see that field lines point away from both charges A and B. therefore, both sources are positively charged.
