2. If you change the value of the battery voltage: a. How does the current through the circuit change? (answer, explain, evidence)
b. How does the resistance of the resistor change? (answer, explain, evidence)

c.the charges if the proton and electron and gravity

d

explanation:

v=uf/(u-f)

= 5.10/(5-10) convex lens has positive focal length

=50/-5

=-10 cm (formed at other side)

force tends to be low and long diustance masses are high
