Well, first of all, the truck's velocity is constantly changing, not 'uniform'.
Velocity consists of speed and direction. So, even if the truck's speed is
constant, its direction keeps changing as long as it's on a circular curve,
so its velocity is constantly changing.
The force needed to keep a mass moving in a circle is
F = (mass) x (speed)² / (radius)
3300 N = (1600 kg) (13 m/s)² / R
3300 kg-m/s² = (1600 kg) (169 m²/s²) / R
R = (1600 kg) · (169 m²/s²) / (3300 kg·m/s²)
= (1600 · 169 / 3300) meters
= 81.9 meters
Answer:
Well depending on who you are and what your personality type is then you could be just as involved and still not liking the sport. Some people will still pay just as much attention because they would not want to be a poor sport.

Explanation:
First last of thermodynamics, just discusses the changes that a system is undergoing and the processes involved in it. It explains conservation of energy for a system undergoing changes or processes.
Second law of thermodynamics helps in defining the process and also the direction of the processes. It tells about the possibility of a process or the restriction of a process. It states that the entropy of a system always increases.
For this to occur the energy contained by a body has to diminish without converting to work or internal energy. So imagine a machine which works with less than efficiency, this means there are losses but they don’t show up anywhere. But the energy is obtained from a higher energy source to lower.
The easy way to do this is with an imaginary device that extracts zero-point energy to heat a quantity of gas. Energy is being created, so the first law is violated, and the entropy of the system is increasing as the gas heats up.
First law is violated since the energy conversion don't apply but the direction of work is applied so second law is satisfied.
The change in temperature was [ (37) - (-5) ] = 42 Fahrenheit degrees.
Kelvins and Celsius degrees are 9/5 (or 1.8) the size of Fahrenheit degrees.
42 F-degrees / 1.8 K per F-degree =<em> 23 and 1/3</em> Kelvins.
<u>Check,</u> using °C = (5/9) (°F - 32) and K = 273.15 + °C :
-5° F = -20.566° C = 252.594 K.
+37° F = 2.778° C = 275.928 K
(275.928K - 252.594K) = <u>23.334 K</u> close enough yay !
