Water displacement is the least difficult approach to decide the volume of an unpredictably formed or complex object. Rather than making various estimations and computations that might be inclined to error, it is just important to submerge the object in fluid and note the volume displaced. Ordinarily, this would be finished utilizing an aligned holder so the volume when inundation can be noted.
At the point when used to calculate the volume of a solid object, the drenching must be aggregate, and care taken to guarantee that no air is caught in any holes. Nonetheless, displacement can likewise be utilized to ascertain the heaviness of a vessel, in which instance obviously, the inundation isn't add up to; the vessel is permitted to drift and, as Archimedes broadly found, its weight will then be equivalent to that of the volume of water displacement.
Answer:
Acceleration at its most basic is the act of increasing your running speed. From a standing start (or blocks), you explode into action. If you’re already running, you pick up the pace. Acceleration continues until you can no longer increase your speed, at which point you achieve maximum velocity (top-end speed). Acceleration seems simple enough. The plus means your increasing speed, the k=minus means your decreasing in speed.
Explanation:
False. p waves, than s waves
Answer:
The star-sphere discovered by the Greeks and other ancient civilizations which shows the physical location in space of the nearby stars.
Explanation:
The celestial sphere is an ideal sphere, without defined radius, concentric with the terrestrial globe, in which the stars apparently move. Some ancient civilizations such as the Greeks assumed that the stars were attached to a celestial sphere, which revolves around the earth, while our planet is always immobile.
Answer:
2800000J
Explanation:
Parameters given:
Mass = 920kg, weight = 920 * 9.8 = 9016N
Distance = 310m
Angle of inclination = 6.5°
Work done is given as :
W = F*d*cosA
Where A = angle of inclination
W = (9016 * 310 * cos6.5)
W = 2776993.59J
In 2 significant figures, W = 2800000J
