Quiz: Electricity, Magnetism & Circuits 3 of 203 of 20 Items Question POSSIBLE POINTS: 1.04 Choose two reasons below that would support your claim that Greeley DOES NOT have an ideal location for wind turbines. Greeley is a populated area and has lots of buildings. Greeley has inconsistent, gusty wind patterns. Greeley doesn't have any birds to get caught in the wind turbine. Greeley has a lot of open space. Greeley is sunny for about 350 days a year. Skip to navigation Imagine a skater riding their board down a steep hill. At which point would the skater's potential energy be the highest? At the top of the hill At the bottom of the hill In the middle of the hill

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 the first electromagnet (a). this is because it has more coils around the ferromagnetic material. increasing the number of coils increases the surface area in which the metal interacts with the current in the coil. this enables more atoms in the metal to become aligned hence becoming more magnetized.

i think its d if wrong im sorry
