I think the correct answer from the choices listed above is the first option. One of the challenges of wind power is the <span>location of wind farms. Wind farms require large areas in order to function. It consumes a lot of space. Hope this answers the question.</span>
Answer:
By dropping a pencil from a certain fixed height again and again it will make the target super messay with marks of dot everywhere on the target and some even out side the target.
Explanation:
Answer: Carbon dioxide is the primary greenhouse gas emitted through human activities. In 2019, accounted for about 80 percent of all U.S. greenhouse gas emissions from human activities. Carbon dioxide is naturally present in the atmosphere as part of the Earth's carbon cycle (the natural circulation of carbon among the atmosphere, oceans, soil, plants, and animals. Human activities are altering the carbon cycle–both by adding more to the atmosphere, and by influencing the ability of natural sinks, like forests and soils, to remove and store from the atmosphere. While emissions come from a variety of natural sources, human-related emissions are responsible for the increase
Explanation:
Answer:
<-0.45, 0, 0> kgm/s
Explanation:
The change in momentum would equal to the impulse generated by force F = <-0.3, 0, 0> over time duration of Δt = 1.5 second. The impulse is defined as the product of force F and the duration Δt
So the change in momentum is <-0.45, 0, 0> kgm/s
Answer:
Explanation:
Impulse on an object is given by .
However, it's also given as change in momentum (impulse-momentum theorem).
Therefore, we can set the change in momentum equal to the former formula for impulse:
.
Momentum is given by . Because the truck's mass is maintained, only it's velocity is changing. Since the truck is being slowed from 26.0 m/s to 18.0 m/s, it's change in velocity is 8.0 m/s. Therefore, it's change in momentum is:
.
Now we plug in our values and solve:
(two significant figures).
