Answer:

D. Wind turbines take up a lot of space.

Explanation:

In wind turbines the kinetic energy received by the air molecules is converted into electrical energy by the use of turbines

So here in order to get more kinetic energy from air we need more crossectional area of the wind mill to interact with the air

So here we need the large size of turbines

so this is the main disadvantage of the wind turbines because it needs large area to install the whole setup also the efficiency of this turbine is small so it needs large number of wind mills to setup good output power

so correct answer will be

D. Wind turbines take up a lot of space.

Describe how impacts between objects in the solar system have helped create notable features in the solar system such as craters

konstantin123 [22]

When 'The big bang' happened lots of large pieces of molten rock was flying around the solar system. As the rocks crashed together they got bigger and as the got bigger they attracted more rocks. Some scientists think that a large piece of molten rock hit the still developing Earth and created the Moon. This impact also caused the Earths angled spin. The Moon got trapped in Earth's orbit and has stayed ever since. Small astroids have hit the Moon causing craters. The Earth doesn't get hit as much because of our thicker atmosphere. Hope this helps!

Light-rail passenger trains that provide transportation within and between cities speed up and slow down with a nearly constant

Nataly [62]

Answer:

v = 25 m / s

Explanation:

For this exercise we use the relations and kinematics

first part, the train accelerates from v₀ = 7.0 m/s to 13 m/s in a time t = 8.0 s

v = v₀ + a t

a = $\frac{v- v_o}{t}$

a = $\frac{13-7}{8}$

a = 0.75 m / s²

second part. Accelerate again for t = 16 s

v = v₁ + a t

for this interval the initial velocity is v₁ = 13 m / s

v = 13 + 0.75 16

v = 25 m / s

Azaria's pet lizard runs a distance of 45 meters in 24 seconds. What is the speed of the lizard?

san4es73 [151]

Question:

Azaria's pet lizard runs a distance of 45 meters in 24 seconds. What is the speed of the lizard?

_________________________________________________

Solution:

We are given,

Distance = d = 45 m
Time = t = 24 s

Speed is given by:

Speed = s = d/t

Putting the given values,

s = (45 m)/(24 s)

=> s = 1.875 m/s
