Answer:
2795.3 J
Explanation:
distance, d = 28 feet = 8.53 m
Force, F = 80 lb = 356 N
Angle, θ = 23°
Work = F x d x cos θ
W = 356 x 8.53 x cos 23
W = 2795.3 J
Thus, the work done is 2795.3 J.
Thermal energy is an example of kinetic energy<span>, as it is due to the motion of particles, with motion being the key. Thermal energy results in an object or a system having a temperature that can be measured. Thermal energy can be transferred from one object or system to another in the form of heat.</span>
Kepler's first "law":
The orbits of the planets are ellipses, with the sun at one focus.
This would include Mars.
A cheetah can run really fast because it is slender which means it is very lightweight and it can move quickly and quietly
