Answer: 2812500 joules
Explanation:
Mass of car = 1500kg
Velocity of car = 75mph
Kinetic energy = ?
Recall that kinetic energy is the energy possessed by a moving object, and it depends on its mass M and velocity, V
Thus, Kinetic energy = 1/2 x mv^2
= 1/2 x 1000kg x (75mph)^2
= 0.5 x 1000kg x (75mph)^2
= 500 x 5625
= 2812500 joules
Thus, the car travels with a kinetic energy of 2812500 joules
Prevailing definitions of climate are not much different from “the climate is what you expect, the weather is what you get”. Using a variety of sources including reanalyses and paleo data, and aided by notions and analysis techniques from Nonlinear Geophysics, we argue that this dictum is fundamentally wrong. <span>In addition to the weather and climate, there is a qualitatively distinct intermediate regime extending over a factor of ≈ 1000 in scale.Climate changes is projected to affect individual organisms, populations, ... Overall, there is a strong correlation between topographic slope and velocity from ... the ecosystems they live in—will adapt to these changes, or if they even can.</span>
Hello,
The answer is option C "<span>thermosphere".</span><span>
Reason:
The troposphere is the layer of the air that the harmful heat rays (from the sun is mostly absorbed). The thermosphere is directly above the exosphere which is the sphere with the thin layer of the sphere therefore the answer should be option C.
If you need anymore help feel free to ask me!
Hope this helps!

Answer: The correct answer is "The switch is closed, completing the circuit".
Explanation:
Electromagnet: It is a temporary magnet. When the iron rod is wounded by the coils and the current is passed through it then it becomes magnetized and behave like a temporary magnet as long as the current flows through it.
When you push the button of a doorbell then the circuit completes and the current starts flowing through the circuit. The electromagnet is activated.
It causes a buzzer to go off. The hammer strikes the bars which creates sound.
Therefore, the correct answer is "The switch is closed, completing the circuit".
The force that is acting upon the plane is simply force
due to gravity. To solve, we use Newtons first law:
F = m a
where m is mass of the object, a is acceleration due to
gravity = 9.8 m/s^2
Calculating for F:
F = 140,000 kg * 9.8 m/s^2
<span>F = 1,372,000 N</span>
