The seasons basically wouldn't change, because basically only one spot would be facing directly at the sun the whole time, so it would be summer there forever, and the edges that barely get any sun would be in eternal winter.
I would say Elastic Potential Energy is a form of Mechanical Energy, because there is an associated motion with it.
I would also say Gravitational Potential Energy is a form of Mechanical Energy.
Chemical potential energy is not a form of Mechanical Energy, it is actually a form of Chemical Energy. It is actually the energy contained in the chemical nature of a fluid.
<span>When T = room temperature
L = 1.0000m+2.4×10^-5m/°C*0°C = 1.0000m+0=1.0000m
change in the length = l2-l1 = (1.0000m+2.4×10^-5m/°C*T2)-(1.0000m+2.4×10^-5m/°C*T1) = 1.0000m+2.4×10^-5m/°CT2-1.0000m-2.4×10^-5m/°CT1=2.4×10^-5m/°CT2-2.4×10^-5m/°CT1=2.4×10^-5m/°C(T2-T1)
So we don’t need at all the 1.0000m data, we just need T2-T1, which is the difference between room temperature and the current temperature, which is 13.6°C.
change in the length = 2.4×10^-5m/°C*13.6°C = 3.264*10^-4m = 0.3264 mm = 326.4 micrometers</span>
displacement is given by equation
now at t = 5 s the position is
similarly position at t = 9 s
so the displacement of object in given interval of time will be
time interval
now the average velocity will be given as
so its average speed is 252 m/s
I’m pretty sure the answer is C. Any change of state or movement requires energy
