Velocidad angular = (angulo total) / (tiempo total)
Velocidad angular = (1080 grados) / (20 segundos)
Velocidad angular = (1080/20) g/s
Velocidad angular = 54 g/s
Pero 180 grados = π radianes
V.A. = (54 g/s) x (π rad / 180 g)
V.A. = (54π gr-rad / 180 seg-gr)
<em>V.A. = 0.3π rad/seg</em>
V.A. = aproximadamente 0.942 rad/seg
Water pollution is a major problem resulting from the oil industry in eastern Alberta, Canada.
Hope it helps!
Answer:
Springs are made of a variety of materials including copper and various forms of steel. The most common is high carbon steel as it is cheap, easy to work and a couple of other important properties.
Copper springs exist as well, but copper is more expensive than steel. However, in an environment where corrosion resistance is important, copper springs are a good alternative.
Explanation:
1.47x10^5 Joules
The gravitational potential energy will be the mass of the object, multiplied by the height upon which it can drop, multiplied by the local gravitational acceleration. And since it started at the top of a 60.0 meter hill, halfway will be at 30.0 meters. So
500 kg * 30.0 m * 9.8 m/s^2 = 147000 kg*m^2/s^ = 147000 Joules.
Using scientific notation and 3 significant figures gives 1.47x10^5 Joules.
It is beacuse of fluid If there is no fluid, there is no drag. Drag is generated by the difference in velocity between the solid object and the fluid. If this statement is correct then how can there be drag in space if there is no air?
