Answer:
Yes, as today human activities are the main cause for climate change.
In recent years, due to the over-consumption of primary sector products, the reckless over-consumption of natural resources and the increase of the earth's population, the natural environment has deteriorated, resulting in an imbalance between the countries of the developed and developing world in terms of climatic and environmental security. The global purpose of states, institutions and associations is to work together for sustainable development at all geographical levels and to fight inequality at the international level. At the same time, it is characteristic that a global movement has developed to demand the equal distribution of environmental burdens and climate justice.
Answer: The last part of the question has some details missing which is ; (Assume that the molecule's velocity is perpendicular to the two sides that it strikes.) molecule v=482 m/s molecule momentum=2.56 x 10^(-23)
Explanation:
- The momentum of the molecule is 2.56 x 10^(-23) .
- Particle hits the wall and bounces.
- Momentum is reversed. Change in momentum = impulse
- This is Force x time.
- Momentum change happens at a wall after each trip.
- time required = distance /speed
- Average force = impulse / time
- = 2 x 482 x 2.56 x 10^(-23) / (0.17 x 2)
- = 7.76 x 10^20N, is the average force the molecule exerts on one of the walls of the container.
Answer:
92km
Explanation:
Given parameters:
Duration of the journey = 6hrs
Average speed = 58km/hr
Now, let us find the total distance of the journey;
Distance = Speed x time
Distance = 58 x 6 = 348km
So;
Average speed for the first 4hrs = 64km/hr
Time = 4hrs
Distance = 64 x 4 = 256km
For the rest of the journey, the student will cover;
= 348km - 256km
= 92km
The most reactive element of this list is Chlorine, the next most reactive is bromine, and the least reactive is iodine.
All of these three elements are group 7 elements in the periodic table. It is known that the reactivity of group 7 elements decreases down the group. The most reactive element in this group is Flourine with reactivity decreasing down the group.
The reason for this decrease in reactivity is that as you go down the group, the distance between the positive nucleus that attracts valence electrons increases, decreasing the electrostatic attraction between the nucleus and the outer electrons. The other reason is that the electrons in lower energy levels closer to the nucleus repel and shield the electrons in the outermost shell or energy level of the atom.
Chlorine>Bromine>Iodine.
TheThe distance they have covered for trip is 219Km.
<h3>What do you mean by uniformly accelereted motion?</h3>
When an object is traveling in a straight line with an increase in velocity at equal intervals of time.
The total time for the trip is
T→ t1+ 22 min = t1+ 0.367 h ,where t1 is the time spent traveling at
V1= 89.5 km/ h .
the distance traveled is ∆x = V1t1=Vavg T
after applying value and calculating it we get
t1= 2.44h for a total time of
t total we get 2.81 h .
∆x =V1T1 = VavgTtotal
∆x = 77×2.81= 219 Km
