Avelocity selector is built with a magnetic field of magnitude 5.2 t and an electric field of strength 4.6 × 10 ^4 n/c. the directions of the two fields are perpendicular to each other. at what speed will electrons pass through the selector without deflection? let the charge of an electron q = −1.6 × 10 ^ −19

a.8.8 × 10^3 m/s
b 2.4 × 10 ^ - 15 m/s
c 7.9 × 10 ^ 13 m/s
d 2.0 x 10 ^ 4 m/s

In which situation has the independent variable for the experiment been changed? check all that apply. changed from counting the number of duckweed at day 0 and day 14 to counting them every day changed from testing duckweed growth in beakers to testing duckweed growth in large outdoor tanks changed from testing the effect of ph on duckweed growth to testing the effect of light levels on duckweed growth changed from testing the effect of acid ph on duckweed growth to testing the effect of basic ph on duckweed growth
