Which of the following is true for a parallel circuit? the current is the same across all resistors in the circuit. the voltage is the same across all resistors in the circuit. as more resistors are added, the current will decrease. the sum of the voltage drops will equal the total voltage

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

the answer is c. the lower legs are levers, and the knees are fulcrums. the ankles hold the loads.
