Please help I'm having a mental breakdown In a series circuit, Vsource =20.0 V, R1 = 30.0 Ω, and R2 = 12.0 Ω. In 10.0 s, how many coulombs of charge pass through the circuit?

I have a test tomorrow morning and I'm pretty sure something like this will be on it so please help me :(

I would also have a mental breakdown

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

pretty sure it's false
