What else can I help you with?
Which nuclear radiation can be stopped by paper?
Alpha radiation can be stopped by paper because alpha particles are large and heavy, which makes them easier to block. Paper is thick enough to absorb the particles before they can penetrate through.
Which type of objects absorb heat most readily?
The objects that absorb heat most readily are those with more of the following qualities:the object is largethe object has a large surface areathe object is blackthe object has a matte finish (it is not shiny)the object is made from a conductor such as metalthe object is much colder than its surroundingsthe object has a high specific heat capacity
Does heat move from a warmer object to a cooler object?
Yes, heat typically moves from a warmer object to a cooler object in order to reach thermal equilibrium. This transfer of heat occurs through various mechanisms such as conduction, convection, and radiation.
When an object is falling its motion is most affected by air resistancce when?
The faster it falls, the more it is affected by air resistance, since air resistance increases with speed. What usually happens in practice is that the object falls faster and faster, and eventually approaches the "terminal velocity" - a speed at which the force of gravity and the force of friction are in balance.
In order for a small object to have a large momentun the object needs to be stationary true or false?
False. Momentum is a product of an object's mass and velocity, so even if the object is small, it can have a large momentum if it has a high velocity. It doesn't need to be stationary to have a large momentum.
Why does a large object absorb thermal energy faster than a smaller object?
A greater surface area allows for greater energy transfer.
Why can both the sun and earth be treated as blackbodies?
Both the sun and earth can be treated as blackbodies because they absorb and emit radiation at all wavelengths. A blackbody is an idealized object that absorbs all incoming radiation and emits radiation based on its temperature, which is true for both the sun and earth to a certain extent.
Which type of land surface will most likely absorb the greatest amount of incoming solar radiation?
A dark, rough surface such as asphalt or forest will absorb the greatest amount of incoming solar radiation, as they have low albedo (reflectivity) and a large surface area for absorption.

How does the presence of oxygen in our atmosphere help reduce the amount of ultraviolet radiation that reaches the earths surface?
Oxygen in the atmosphere helps to absorb and scatter incoming ultraviolet (UV) radiation from the sun. This process occurs in the stratosphere, where oxygen molecules break apart the incoming UV radiation. This absorption and scattering of UV radiation by oxygen prevent a large amount of harmful UV radiation from reaching the Earth's surface.
What happens to temperature as altitude increases in the exosphere?
In the exosphere, temperature increases with altitude. This is because the few particles in this layer can absorb large amounts of solar radiation, leading to higher temperatures the higher you go.
Does the large intestine absorb salts?
no , it does not
Does heat move from a warmer object to a cooler object?
Yes, heat typically moves from a warmer object to a cooler object in order to reach thermal equilibrium. This transfer of heat occurs through various mechanisms such as conduction, convection, and radiation.
What doe large instestine do?
The large intestines job is to absorb nutrients
Primary function in the large intestine?
The primary job of the large intestine is to pass waste and to absorb water into the body.
What does the blood absorb in the large intestine?
Water.
