Select all that apply. a) consisted of one star with eight orbiting planets b) emerged from a very tiny region and expanded c) consisted primarily of iron and nickel in the past d) was hotter and denser in the past e) consisted primarily of carbon and oxygen in the past f) was cooler and less dense in the past

wind moving at higher speeds will transfer more energy to the water, resulting in stronger waves.

laticia draws the diagram below to show earth’s magnetic field.

answer

the arrows to the right of earth should point up.

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
