The magnitude of the air drag when the object is traveling at terminal velocity is C. 850 Newtons
Explanation:
There are only two forces acting on the object here:
- The force of gravity, of magnitude , acting downward
- The air drag, , acting upward
Therefore, the equation of motion for the object is
where m is the mass of the object and a its acceleration.
The object in this problem is traveling at terminal velocity: this means that the acceleration is zero, so
a = 0
Therefore the equation becomes
which means that the magnitude of the air resistance is equal to the magnitude of the force of gravity:

Answer:
404K
Explanation:
Data given, Kinetic Energy.K.E=8.37*10^-21J
Note: as the temperature of a is increase, the rate of random movement will increase, hence leading to more collision per unit time. Hence we can say that the relationship between the kinetic energy and the temperature is a direct variation.
This relationship can be expressed as
where K is a constant of value 1.38*10^-23
Hence if we substitute the values, we arrive at
converting to degree we have
