Dependent variable is your answer.
10 – 3 + 8 = 15 meters
10 + 3 + 8 = 21 meters
Her total traveled is 21 meters, displacement is 15 meters.
Answer:
it means the velocity is changing.
the rate of change of velocity is acceleration
so it means the body is accelerated at 2m/s^2
this is first law of thermodynamics in which meaning of each term is given as
= change in internal energy
Q = Heat given to the system
W = work done by the system
so here we will have
∆U=Q-W , which means <u>Change in internal energy</u> in a system is equal to <u>heat given</u> added, minus <u>work</u> done by the system. the units for these variables are in <u>joule</u> .
<span>a) The law of conservation of momentum is satisfied because there must be air (and other combustion byproducts) expelled behind the aircraft as it moves forward. The collective momentum of those gases is equal in magnitude and opposite in direction to the forward momentum of the aircraft.
b) The aircraft obeys conservation of energy because it is simply converting energy to different forms. In its stationary form, there existed latent chemical energy in both the fuel on board and the oxygen in the air. As the aircraft moves, some of that chemical energy is converted into kinetic energy and heat, but it is indeed conserved.</span>
