What are different ways to manipulate air pressure?
Five ways:Temperature (increase in temperature means increase in pressure.)Velocity (increase the speed means decrease in pressure.)Amount of air particles (more particles means more pressure.)Changing the container (More space means less pressure.)Altitude (increase in altitude means decrease in pressure.)
What happens to drag as altitude increase?
As altitude increases, the density of the air decreases, resulting in a decrease in drag on an object moving through the air. This is because there are fewer air molecules to create resistance against the object's motion.
Would adding soap to water increase or decrease the curve of its meniscus?
Adding soap to water would decrease the curve of its meniscus. Soap reduces the surface tension of water, which causes the liquid to spread out more and form a flatter meniscus compared to pure water. This is because the cohesive forces that create the curvature of the meniscus are weakened when surfactants like soap are introduced.
On the molecular level what causes gas pressure?
On the molecular level pressure is caused by individual gas molecules interacting with the surfaces of a container. Pressure is defined as force per unit area, so in the most basic level pressure can increase with an increase in force applied to the container or a decrease in area the molecules are interacting with. The decrease in area can be from a smaller container, or an increase in force can be from an increase in the velocity of the molecules. This increase in velocity is usually due to an increase in energy (typically heat).
What impact would a flood have on the biodiversity of a community?
A flood can have both positive and negative impacts on biodiversity of a community. It can disrupt habitats, lead to loss of species, and decrease biodiversity in the short term. However, floods can also create new habitats, increase nutrient availability, and promote species diversity in the long term as ecological succession occurs.
When are electromagnets used to increase or decrease the voltage of electric currents?
Electromagnets are never used to increase or decrease the voltage in a circuit. These magnets in conjunction with a rotating device (an armature) can create a voltage but the do not have any effect on a voltage.
Which type of change can produce stress?
Since stress is a function of Force per Area an increase in force will increase stress and vice versa. Since stress is inversely proportional to area an increase in area will create a decrease in stress and an decrease in area will produce an increase in stress. So look for the increase in force or the decrease in area in the given situation (even figuratively speaking).
Do rear spoilers increase gas mileage?
Spoilers decrease gas mileage. Spoilers are designed to create down force, which creates drag. The drag will increase gas usage.
What happens when you decrease or increase the wave period?
When you decrease the wave period, the waves will be closer together and have a higher frequency. This can create choppier and rougher conditions on the water. When you increase the wave period, the waves will be farther apart and have a lower frequency, resulting in smoother sailing conditions with longer intervals between waves.
How can you increase the magnitude of friction between two surfaces How can you decrease the magnitude of friction?
To increase friction, you can increase the roughness of the surfaces in contact, increase the normal force pressing the surfaces together, or use materials with higher coefficients of friction. To decrease friction, you can use lubricants to reduce surface roughness and create a barrier between the surfaces, reduce the normal force acting on the surfaces, or use materials with lower coefficients of friction.
Does rowing a boat increase or decrease friction?
Rowing a boat increases friction. The oars create resistance against the water, which generates friction that helps propel the boat forward.
How did technology develop?
Through the natural human tendency to create and adapt.

How do levers create a trade-off?
Levers create a trade-off by providing mechanical advantage either in force or distance. When a lever is used to increase force, the trade-off is a decrease in distance over which the force is applied. Conversely, when a lever is used to increase distance, the trade-off is a decrease in the amount of force that can be exerted.
Does the spoiler of a car increase or decrease friction between the tires and the road?
The spoiler on a car is meant to create down force on the back or front of a car depending on where it's placed... Which means that yes it does increase friction but it also helps with traction at higher speeds
What are the minimum changes in set up to increase velocity ratio of single purchase crab?
To increase the velocity ratio of a single purchase crab winch, you can either increase the diameter of the drum or decrease the diameter of the driving sheave. Another option is to increase the number of wraps of the rope on the drum to create more friction and improve the mechanical advantage.
What does diagnostic medical sonography mean?
Diagnostic Medical Sonography is a type of ultrasonic photography. It is commonly used to create a picture of the developing child inside a pregnant women's womb.
