What else can I help you with?
Objects with three very different sizes and weights are dropped off a tower on the moon Which factor of the objects will determine which hits the ground first?
The lead ball and the feather would hit the surface at the same time because there is no atmosphere on the moon. Gravity pulls on both objects in such a way as to produce the same acceleration, so they will hit at the same time. On earth the problem is complicated by the presence of air, and that it exerts forces on the objects. The feather is affected by aerodynamic drag far more than the lead ball, and is thus slowed immensely in comparison.
What would happen if additional weight was added to a piece of crust?
Adding weight to a piece of crust could cause it to deform or sink further into the underlying mantle. This could lead to increased pressure and potentially trigger earthquakes or volcanic activity, especially if the added weight is significant.
Why is the density of lead the same on the Moon as it is on Earth?
Density is based off mass and volume, not weight and volume. Weight is a measurement of gravity, and changes based on strong the pull of gravity is in the area. Mass is a measurement of the amount of matter in an object, and does not change based on the pull of gravity. Density is Mass/Volume. Volume is a measure of how much space an object occupies. The more condensed matter is, the higher its density.
Would most likely occur when an air mass is resting on cooler ground?
If an air mass is resting on cooler ground, it can lead to the air mass becoming cooler as it picks up the temperature of the ground through conduction. This may result in the formation of fog or low-level clouds due to the cooling of the air near the surface. Additionally, there could be a stable atmospheric condition with little vertical mixing, leading to the trapping of pollutants near the surface.
How can sailors tell if they are near land if they cannot see land at all?
Sailors can use soundings to determine the depth of the water, which can indicate proximity to land. They can also use a lead line to measure the depth and types of seabed materials. Additionally, they can listen for sounds of waves breaking on shore or birds that are often near land.
Under what conditions would a lead weight and a feather fall at the same rate?
If they were dropped in a container from which the air had been removed.
What examples are size weight and shape?
Size: As small as a mouse As big as an elephant Weight as light as a feather as heavy as lead Shape twisted like a pretzel as flat as a pancake
Is 1kg of lead in vacuum heavier than 1kg of feather in vacuum?
No, both 1kg of lead and 1kg of feather would weigh the same in a vacuum because weight depends on mass, and both objects have a mass of 1kg. Gravity affects weight, but in a vacuum, there is no air to provide resistance, so both objects would fall at the same rate.
What conditions would a lead weight and feather fall at the same rate?
The lead weight and feather would fall at the same rate in a vacuum where there is no air resistance to slow them down. In the absence of air resistance, all objects experience the same acceleration due to gravity, regardless of their mass. This is demonstrated in Galileo's famous experiment at the Leaning Tower of Pisa.
What weight more a pound of lead or a pound of feather?
One, the correct term is "Which weighs more: a pound of lead or a pound of feathers?" Two, the answer is that they weigh exactly the same, because they both weigh a pound.
What is the force that opposes the motion of objects in air?
It is air friction. An aeroplane flying into a headwind will use up much more fuel than an aeroplane flying with a tailwind. Air friction means that a feather would take much longer to reach the ground than a lead weight dropped from the same height. Yet, if the feather and the lead weight were to be dropped in a vacuum (not subjected to air resistance) they would both reach the ground at the same time.
What are the homonyms of land?
The homonyms of "land" include "land" as in ground or territory, and "land" as in to arrive or come down to the ground (e.g., a plane landing). Additionally, "land" can refer to a specific area or region, often in a legal context, such as property ownership. These different meanings can lead to confusion depending on the context in which the word is used.
Light as a feather?
think we're talking perception here... eg which is the heaviest - a ton of feathers or a ton of lead ??....
How does slope of land effect oil tanks?
The slope of the land can impact oil tanks by affecting their installation and stability. Installing oil tanks on a slope can lead to uneven weight distribution and potential leaks. It's important to place oil tanks on level ground to ensure proper functionality and prevent accidents.
What is feather of lead romeo and juliet?
Romeo says, "Feather of lead, bright smoke, cold fire, sick health!" He's playing with words, creating oxymorons for the fun of it. A "Feather of Lead" is something which is both light and heavy at the same time. It would have made a great name for a late-60s band, to go along with Led Zeppelin and Iron Butterfly.
Is a ton of lead heavier than a ton of feather?
They both weigh a ton
What does feather or lead mean?
"Feather or lead" typically refers to the idea of weighing something lightly or heavily, often in a metaphorical sense. It can denote the contrast between lightness (feather) and heaviness (lead), symbolizing different approaches or outcomes in various contexts. This phrase may be used to describe decision-making, emotional states, or even physical burdens. Ultimately, it emphasizes the duality of choices and their impacts.
