Answer:
We know that the torque can be calculated as follows:
T = rpsinα
With r being the distance of the body from the center of the circumference he has as trajectory, p being the momentum of the body and sinα being the sine of the angle between the 2 vectors: r and p.
It's pretty obvious that T is directly proportional to the momentum, that can be written as p = m·v, with m being the mass of the object and v the velocity of the object.
Observations is the answer.
The answer is unbalanced because the numbers 100n and 300n don’t equal each other. If the answer was balanced the numbers would have to equal each other. Also, the answer net force would only be the answer if we were adding the numbers. I hope this helped you! :)
Hurricanes form when hot air and cold air start colliding above water and they start to form a tornado but there is water in the tornado. Certain places on earth are more susceptible to hurricanes because they are closer to the coastlines. For example, in Iowa, and Illinois, they have a lower chance of a hurricane, while Florida, and Washington have a higher rate because they are along the ocean. Hope this helps.
Explanation:
The given data is as follows.
= (4 + 273) K = 277 K
= (22 + 273) K = 295 K
= 21.2
Formula to calculate activation energy will be as follows.
![ln \frac{k_{2}}{k_{1}} = \frac{E_{a}}{R} [\frac{1}{T_{1}} - \frac{1}{T_{2}}]](https://tex.z-dn.net/?f=ln%20%5Cfrac%7Bk_%7B2%7D%7D%7Bk_%7B1%7D%7D%20%3D%20%5Cfrac%7BE_%7Ba%7D%7D%7BR%7D%20%5B%5Cfrac%7B1%7D%7BT_%7B1%7D%7D%20-%20%5Cfrac%7B1%7D%7BT_%7B2%7D%7D%5D)
![ln (21.2) = \frac{E_{a}}{8.314 J/mol K} [\frac{1}{277} - \frac{1}{295}]](https://tex.z-dn.net/?f=ln%20%2821.2%29%20%3D%20%5Cfrac%7BE_%7Ba%7D%7D%7B8.314%20J%2Fmol%20K%7D%20%5B%5Cfrac%7B1%7D%7B277%7D%20-%20%5Cfrac%7B1%7D%7B295%7D%5D)
3.05 = 
= 115116.914 J/mol
or = 115.116 kJ/mol
Thus, we can conclude that overall activation energy (kJ/mol) of the process is 115.116 kJ/mol.
