Which statement accurately describes the motion of the object in the graph above over 10 seconds? Group of answer choices

The object is at rest for 3 seconds and then decreases velocity to 1 cm/s for 3 seconds.

The object is at rest for 4 seconds and then moves forward for 4 seconds at 1 cm/s.

The object moves forward at 1 cm/s, stops, and then increases velocity to 2 cm/s.

The object moves forward at 1 cm/s, stops, and then continues at the same velocity.

correct it is c.) b b

i don't know that i agree with that but what's the question ?

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.

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
