Answer: Around 364 to 480
Answer:
*******
Explanation:
is obviously the correct answer they are both so different yet so alike
Answer:
<h2>
m/s ^2</h2><h2 />
Explanation:
Solution,
When a certain object comes in motion from rest, in the case, initial velocity = 0 m/s
Initial velocity ( u ) = 0 m/s
Final velocity ( v ) = 72 km/h ( Given)
We have to convert 72 km /h in m/s
![72 \: km \: per \: hour](https://tex.z-dn.net/?f=72%20%5C%3A%20km%20%5C%3A%20per%20%5C%3A%20hour)
![= 72 \times \frac{1000}{60 \times 60}](https://tex.z-dn.net/?f=%20%3D%2072%20%5Ctimes%20%20%5Cfrac%7B1000%7D%7B60%20%20%5Ctimes%2060%7D%20)
m/s
Final velocity ( v ) = 20 m/s
Time taken ( t ) = 2 seconds
Acceleration (a) = ?
Now,
we have,
![a = \frac{v - u}{t}](https://tex.z-dn.net/?f=a%20%3D%20%20%5Cfrac%7Bv%20-%20u%7D%7Bt%7D%20)
![a = \frac{20 - 0}{2}](https://tex.z-dn.net/?f=a%20%3D%20%20%5Cfrac%7B20%20-%200%7D%7B2%7D%20)
![a = \frac{20}{2}](https://tex.z-dn.net/?f=a%20%3D%20%20%5Cfrac%7B20%7D%7B2%7D%20)
m/s ^2
Hope this helps...
Good luck on your assignment..
Adaptation will mean taking action to minimize the negative effects of change. ... the use of new tools and techniques for decision-making, For example, projected increases in drought, fire, windstorms, and insect and disease outbreaks are expected to result in greater tree mortality. Fewer trees will reduce Canada’s timber supply, which in turn will affect the economic competitiveness of Canada’s forest industry. This would leave forestry-dependent communities vulnerable to job losses, closure of forestry processing facilities and an overall economic slump.
Ans) A) Centripetal force will be doubled.
See centripetal force F = mv^2/r
That means centripetal force is directly proportional to the mass of the particle
So, if we double the mass, centripetal force will be increased by twofolds.
So, option A) is correct.
Now, looking at the other options,
B) says centripetal force is unaltered which is incorrect as centripetal force has been altered and increased twofold.
Option C) and D) reduces centripetal force which are also not possible here.
So, only Option A) is correct
