Absolute altitude refers to the height of an object above a reference point, typically the Earth's surface, measured in feet or meters. In aviation, it is often used to indicate the altitude of an aircraft above sea level, as opposed to relative altitude, which measures height above the ground. An absolute altitude of 777 would mean the object is 777 feet or meters above sea level.
Cirrus clouds typically form at high altitudes, around 20,000 to 40,000 feet (6,000 to 12,000 meters) above the ground.
Gravity is the force that pulls objects toward the Earth. It is a natural phenomenon by which objects with mass are attracted to each other. Gravity is what keeps our feet firmly on the ground and causes objects to fall when dropped.
An object dropped from near the Earth's surface will fall approximately 4.9 meters (16 feet) in the first second due to the acceleration of gravity. This distance is calculated using the formula s = 0.5 * g * t^2, where s is the distance, g is the acceleration due to gravity (9.8 m/s^2), and t is the time in seconds.
On average, the temperature decreases by around 3.5°F for every 1,000 feet increase in elevation, known as the lapse rate. At 8,000 feet altitude, you can expect the temperature to be around 28°F cooler than at ground level, so it would be approximately 42°F at that height if the ground temperature is 70°F.
When an object is lifted 6 feet off the ground, its potential energy is a certain value based on its height and mass. If the same object is then lifted 12 feet off the ground, its potential energy will be doubled compared to when it was lifted 6 feet. This is because potential energy is directly proportional to the height to which the object is lifted.
The final speed of an object dropped from a height of 100 feet can be found using the equation v = sqrt(2gh), where v is the final speed, g is the acceleration due to gravity (32 ft/s^2), and h is the height (100 ft). Plugging the values into the equation gives v ≈ 80 ft/s.
it strikes the ground at a velocity of 17.9 ft/s
The height, in feet, above the ground at time t, H(t) = 40 + 32*t - 16*t2
In addition to the height of the object, the length of its shadow depends on a few other things that are not described in the question. -- Is the object standing straight upright ? -- Is the shadow cast on the ground or on sometheing else? -- If on the ground, is the ground level ? -- What is the altitude (angle) of the sun ?
a. 144 feet b. 96 ft/sec.
Ignoring air resistance ... Any object dropped near the Earth's surface reaches a speed of 43.9 feet per second after falling 30 feet. The velocity is 43.9 feet per second down. The object's weight makes no difference.
To determine the speed of a pound (or any object) dropped from a height of 30 feet just before it hits the ground, we can use the equation derived from the laws of physics: ( v = \sqrt{2gh} ), where ( g ) is the acceleration due to gravity (approximately 32.2 feet per second squared) and ( h ) is the height (30 feet). Plugging in the values, the speed would be approximately ( v = \sqrt{2 \times 32.2 \times 30} ), which yields a final speed of about 24.3 feet per second just before impact.
== == Science Major: Altitude is height above mean sea level (MSL) or true altitude, which means in reference to what sea level is on the ground, or height above ground level (AGL), which is also called absolute altitude, which means height above the ground with no reference to the ground's height above sea level. In example, if the sea level in a certain place is 100 feet and you are 250 feet above the ground, your altitude above sea level would be 350 feet, and your altitude above ground level would be 250 feet.
Did the height of the basketball net from the ground change from 12 feet to 10 feet or from 10 feet to 12 feet Did the height of the basketball net from the ground change from 12 feet to 10 feet or from 10 feet to 12 feet
198 feet 10.66 inches
When building a model of an object to scale, it means that the height of the object is proportionally greater than the height of the model. Usual scales are 1:100 or 1:144, meaning that if the height of the model is 3 feet, the height of the actual building would be 300 feet or 432 feet.
