Smithers thinks that a special juice will increase the
productivity of workers. He creates two groups of 50
workers each and assigns each group the same task
(in this case, they're supposed to staple a set of
papers). Group A is given the special juice to drink
while they work. Group B is not given the special
juice. After an hour, Smithers counts how many
ch group has made. Group A made 1,587 stacks, Group B
2.6

they start with the same

the minimum amperage that the current in this wire would have to have so that its weight is completely supported by the magnetic force due to earth's field, assuming that no other forces except gravity act on it

i think the answer is a, hope this : )

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
