Find the second charge if one charge is 22 C and it is placed .4m away while experiencing an attractive electrical force of 7500N. Question 5 options:
A. 6.06 x 10^-9 C; positive
B. 3.03 x 10^-9 C; positive
C. 3.03 x 10^-9 C; negative
D. 6.06 x 10^-9 C; negative

terd muffin is the correct answer

i believe the answer would be:

d. violin, clarinet, french horn, and tuba

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s
