What is one way that Earth's ocean currents help regulate global climate? A. by transmitting sunlight from the ocean surface to the ocean floor B. by creating an uneven distribution of the Sun's energy across Earth's surface C. by carrying cold water and floating ice from the Equator toward the poles D. by moving warm water and precipitation from the Equator toward the poles

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
