Why don't objects need to be streamlined in space?
In space, there is no atmosphere or air resistance, so objects do not encounter drag forces that can slow them down. This means that streamlined shapes, which reduce air resistance on Earth, are unnecessary in the vacuum of space. Objects can travel freely without the need for aerodynamic designs, making their shapes less critical for movement. However, for operations involving re-entry into an atmosphere, streamlining becomes essential again to manage heat and drag.
Why should you never weigh objects while still hot?
A warm or hot object will create a convection current in the air around the balance pan. This fluctuating force reduces the air pressure on the balance pan and can make it difficult to obtain a stable reading.
Witch is easier to play obeo or the flute?
The oboe is generally regarded as harder to play than the flute because of the air pressure that is required when blowing into an oboe reed and because of the sensitivity of the oboe reed regarding a proper amount of moisture.
What can cause water to leak in on the passenger side floor board and rear passenger side floor board of a 2001 Pontiac Grand Prix only does this when the air conditioner has been on?
air conditioning can cause moisture in the air to condense, especially around vents where the air is moving at high speed. If you live in a very humid area, this could be caused by the air conditioning being so cold that the moisture is condensing out as soon as the cold air meets the warm, damp air. Try running the air conditioner at a higher temperature setting, or on 'normal' instead of 'max'. The more likely senario is that water is leaking in from an area below the windshield under the hood. There is box (under the plastic cover at the bottom of the windshield on the passenger side) that allows air from outside to be pumped inside. If you have this area open you will a see foam seal painted the same color as the vehicle at the base of the box. This so called seal dry rots and GM knows this; however, the seal cannot simply be replaced from what I was told by a windshield replacement shop and a dealer. It is riveted together and must be cut apart and then reassembled. This issue caused the blower motor to seize after the leak corroding the internals of the motor itself.
What is air g?
Air g, or air gap, refers to the physical space or distance between two objects, often used in various contexts such as plumbing, electrical systems, and data security. In plumbing, an air gap prevents contaminated water from flowing back into the clean water supply. In cybersecurity, it denotes a network that is isolated from unsecured networks, such as the internet, to protect sensitive information. It's a crucial concept for ensuring safety and integrity in both physical and digital environments.

How is hair affected by air moisture?
Hair can become frizzy and unruly in humid conditions due to the absorption of moisture from the air. On the other hand, in dry conditions, hair may feel brittle and lackluster as moisture is drawn away from the hair shaft. It is important to manage hair with appropriate products to help mitigate the effects of varying air moisture levels.
Does iron placed in an air conditioned room rust?
Iron can still rust in an air conditioned room if there is moisture present in the air. Air conditioning can reduce humidity levels, but if the room is not well-sealed or if there are other sources of moisture, rust can still occur. It's important to keep iron objects dry to prevent rusting.

What types of objects are most strongly affected by air resistance?
Objects with large surface areas and shapes that are not streamlined are most strongly affected by air resistance. For example, a flat surface such as a parachute or a square sheet of paper will experience greater air resistance compared to a streamlined shape like a sphere or an arrow.
The path of flying objects?
The path of flying objects is typically affected by factors such as gravity, air resistance, and initial velocity. Objects follow a curved path known as a parabolic trajectory due to the influence of gravity. Other factors like wind speed and direction can also affect the path of flying objects.
What is true about air pressure acting on an object?
Air pressure is the force exerted by the weight of the air above an object. It acts in all directions and can impact objects by pushing or compressing them. Differences in air pressure can cause objects to move or be affected in various ways.
What is moisture that falls from to the ground?
Moisture that falls from the ground is called dew. Dew forms when water vapor in the air condenses on the surface of objects on the ground during the night when temperatures drop.
Which of the following objects would be most affected by air resistance when falling?
The object with the largest surface area relative to its mass would be most affected by air resistance when falling. This means objects with a larger surface area, such as a feather or a sheet of paper, would experience more air resistance compared to objects with smaller surface areas, like a dense metal ball.
What is meant by free falling objects?
Free falling objects are those that are only under the influence of gravity, with no other external forces acting on them. As a result, these objects accelerate towards the ground at a rate of 9.81 m/s² (on Earth) and do not experience air resistance. The motion of free falling objects can be described using the equations of motion.
What type of air hold moisture best?
Warm air generally holds moisture better than cold air. This is because warmer air has a higher capacity for water vapor, so it can hold more moisture before reaching saturation. Cold air, on the other hand, has a lower capacity for moisture and can become saturated more quickly.
What instruments measure air moisture?
Hygrometers are instruments used to measure air moisture. They can either be mechanical or electronic devices that provide readings of humidity levels in the air. Other instruments like psychrometers and hygrometric tables are also used to measure air moisture.
