A 20 kg mass is held above the ground What is the approximate potential energy of the mass with respect to the ground?
The potential energy of an object with respect to the ground can be calculated using the formula PE = mgh, where m is the mass (20 kg), g is the acceleration due to gravity (approximately 9.81 m/s^2), and h is the height above the ground. If the mass is, for example, 2 meters above the ground, the potential energy would be approximately 392.4 J.
If fifty pounds were sitting on the ground and on top of a flag pole base would it offer as much resistance to the wind as fifty suspended slightly above the ground and strapped to the pole?
No, the weight on the ground will provide more resistance to wind because it increases the pole's stability by lowering its center of gravity. When suspended above the ground, the weight's influence would be less effective in countering the wind force on the pole.
Is the height above the ground from which the ball is thrown was increased the time of flight of the ball would?
If the height from which the ball is thrown is increased, the time of flight of the ball would increase as well. This is because the initial velocity of the ball would be higher, leading to a longer time for the ball to reach the ground.
In which position would an object have the GREATER amount of potential energy?
An object would have greater potential energy when positioned higher above the ground due to its increased gravitational potential energy.
What is the gpe of a 500g box of chocolates 2 m above the ground?
The gravitational potential energy (GPE) of the 500g box of chocolates 2m above the ground can be calculated using the formula: GPE = mass * gravity * height. Assuming gravity is 9.81 m/s², the GPE would be approximately 98.1 joules.
Why is the altitude of the sun measured in degrees above the horizon - rather than in feet and meters like aircraft?
The altitude of aircraft is measured above the ground, not above the horizon, and it's a distance. The altitude of the sun is not measured above the ground, and it's not a distance. If it were, it would always be some number near 93 million miles. The altitude of the sun is the angle that an observer sees between his horizon and the sun, and it's different for different observers in different places.
Where in the sky would a star with an azimuth of 180 degrees and an altitude of 20 degrees be found?
A star with an azimuth of 180 degrees would be due south, and an altitude of 20 degrees would place it 20 degrees above the horizon. So, the star would be in the southern part of the sky, 20 degrees above the horizon.
What is 70 degrees above the north horizon?
Looking toward the north, the ray from you through the point 70 degrees above the horizon. 90 degrees would be directly overhead.Notation such as this is used to announce sightings of the International Space Station, for example:
What is the relationship between a particular latitude and the angle of Polaris above the horizon at that latitude?
The angle of Polaris above the northern horizon is very nearly equal to your north latitude, within about 1/3 of a degree. So it's over your head when you stand at the north pole, it sits nominally on your north horizon when you stand anywhere on the equator, and if you're south of the equator, you can never see it at all.
Is 55 degrees above the horizon very low in the sky - ie very close to the horizon?
If the horizon is on a level line of sight, a vertical line directly above the observer forms an angle of 90 degrees. 55 degrees would be quite high, being above 45 degrees.
What latitude on earth is a celestial pole 45 above the horizon'?
At 45 degrees north latitude, the north celestial pole appears 45 degrees above the northern horizon. At 45 degrees south latitude, the south celestial pole appears 45 degrees above the southern horizon.
You can measuring the altitude of a star by measuring the angle between your horizon and the star using a?
We would typically use a sextant to measure the angle of a star above the horizon.
What is the angle of the celestial north pole above the horizon in Frankfurt Germany?
The altitude of the celestial north pole above the northern horizon is exactlythe observer's north latitude on the earth. The center of Frankfurt is very closeto 50° North latitude.
What is the position of the sun in Summer at 6am?
Depending on your location, the Sun is probably low above the northeastern horizon in the northern hemisphere, or above the southeastern horizon in the southern hemisphere.
What is at zero degrees altitude?
At zero degrees altitude, you would be at ground level or sea level. This position marks the horizon line where the sky meets the Earth.
Do pea pods grow above ground or under ground?
Above ground. If they grew underground, they (a) would not be green and (b) would not be peas. +++ The pod is the fruit, and the peas the seeds, of the pea plant.
What if an astronaut was on the far side of the moon during a solar eclipse?
In that case, the Sun would be above the horizon for that astronaut.
