What else can I help you with?
Does electric force require that objects touch?
No, electric force does not require objects to touch in order to act on each other. Objects with electric charge can exert attractive or repulsive forces on each other even when they are not in physical contact.
What doesn't require energy?
Processes such as gravity, diffusion, and osmosis do not require energy input to occur. Additionally, objects at rest do not require energy to maintain their state.
What law says that heavier objects require more than lighter objects to move or accelerate them?
Newton's second law of motion states that the acceleration of an object is directly proportional to the force applied to it and inversely proportional to its mass. This means that heavier objects require more force to move or accelerate them compared to lighter objects.
What objects can move in a vacuum?
Objects that can move in a vacuum are those that do not require air or any other medium to travel, such as light, spacecraft, and particles.
Does conduction require direct contact between objects objects have to be touching?
Yes, conduction does require direct contact between objects for heat transfer to occur. This is because heat is transferred through the collision of particles in direct contact with each other. If there is no direct contact, conduction cannot take place.
How is the mineral xonotlite used?
Xonotlite is used as a component in high-temperature insulation materials, especially in applications that require resistance to heat, chemicals, and high pressure. It is also utilized in the manufacturing of refractory products, such as furnace linings and insulation boards, due to its thermal properties.
What ppe would a plumber require when working in roof space insulated with mineral wool?
When using mineral wool insulation make sure that you wear a snug fitting facemask to prevent nose and throat irritation and also wear protective gloves to prevent the hands from making contact with mineral wool as this can cause severe irritation. Suitable safety goggles should be worn to ensure that loft insulation does not come into contact with the eyes as it will cause extreme discomfort and possibly damage the eyes due to it's abrasive nature. Also important , is that you will need an inspection lamp.
Mineral that your body require in very small amount are called trace mineral what are exanple of trace mineral?
Iodine; reason for iodized salt
Which type of pipe and insulation you should use for AC drain outside steel or PVC or cupper?
Use PVC for the drain line. It does not require insulation.
Living organisms are different from inanimate objects because they?
Living organisms have the ability to grow, reproduce, respond to stimuli, and maintain homeostasis. They also require energy to carry out these functions and have the capacity for evolution and adaptation. Inanimate objects, on the other hand, do not possess these characteristics.
What mineral does hemoglobin require to do its job?
Hemoglobin requires iron to do its job
Does induction require objects to touch?
No induction does not generally require the objects to touch. Induction can mean that one object induces an electrical change in the other object from a distance
Does electric force require that objects touch?
No, electric force does not require objects to touch in order to act on each other. Objects with electric charge can exert attractive or repulsive forces on each other even when they are not in physical contact.
How is insulation measured?
Floors, attics and walls all require insulation of different R-Values which are measured by the thickness of the insulation. The R-Value determines how well the insulation will resist heat flow. The higher the R-Value the more resistance it has to heat and cold. If you are adding to existing insulation there is another factor to consider. You will have to determine the R-Value of the existing to know how much additional insulation to add
Does the 2006 International Building Code require overlapping the flaps of rolled insulation when insulating exterior walls or can the insulation be stapled to the interior of the stud?
Insulation should only be stapled on the edge of the stud. That's what the flap on the edges is for. This creates a vapor barrier and if you compress the insulation enough to staple on the sides this reduces the insulation at that point. Insulation has to be fluffed to get the benefit. It is easier, quicker and does not interfere with the sheetrock in any way.
Why are chemical properties not always used to identify minerals?
Testing the chemical properties of a mineral might damage the mineral sample. Also, these tests can be complex and may require expensive equipment.
Does a high rating mean lots of insulation or little insulation?
It depends what you mean by a 'high rating'!If you mean a high 'voltage rating' then, yes, you will require thicker insulation. But if you mean a high 'power rating', then, not necessarily, because the voltage can be low, while the current is high.Remember, the thickness of insulation depends on the voltage, while the type of insulation (how it withstands higher temperatures) depends on the current.
