Uma carga puntiforme Q cria um campo elétrico E num ponto situado a uma distância d. Para que a intensidade do campo seja quatro vezes maior, a distância à carga deve ser igual a: 1/4 d 1/2 d √2/2 d d)√2d e) 2d

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.

v=ir = 3x15 =45 v

the best answer for these questions would be:

1.            c. is smaller

2.            d) concrete operational

3.            b) interaction with the environment – the children interact with their environment can them learn more.

4.            a) parents who reason openly with children can limit a child’s cognitive ability.
