Calcula la intensidad de la corriente que alimenta una lavadora de juguete que tiene una resistencia de 10 ohmios y funciona con una batería con una diferencia de potencial de 30 voltios

d) the number of neutrons plus the number of protons

the answer is neither ball has a charge.

because if they were both positively charged, they will repel each other.

if they were positively and negatively charged, they will seek.

not moving. pos accel,

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
