Most of the radiation, however, is absorbed by the earth's surface. ... Every surface on earth absorbs and reflects energy at varying degrees, based on its color and texture. Dark-colored objects absorb more visible radiation; light-colored objects reflect more visible radiation.
Answer:
The answer is 3.111111.
Explanation:
It runs 28 m in the first 9 s, and 28 divided by 9 equals 3.1 and the one goes on forever.
I would say A is the answer im not sure tho
1c. The goal of technology is to improve how people live. For example a toothbrush helps prevent cavities and buildup on our teeth.
2a. Science and technology both help improve our lives. Science gives us the knowledge we need to create technology.
2b. A human prosthetic is an example of technology.
2c. Prosthetics are created though scientific study and research. Technology is used to create the material prosthetics are made of and to help design the prosthetics.
3a. Benefits of pesticides: Keeps bugs away from crops, higher crop yields.
Negatives:
pollution, harmful to health
I got all of them except the last one
Answer:
Decrease the number of gas particles, increase the object's area, and reduce the temperature of the gas
Explanation:
<u>TEMPERATURE</u>:
Decreasing the temperature will slow down the molecules. Hence, less no. of collisions will take place between walls of object and molecules. This will result in decrease of pressure.
Therefore, the pressure of a gas can be decreased by increasing its temperature.
<u>NUMBER OF GAS PARTICLES</u>:
Decreasing the number of particles will result in less no. of collisions, hence decreasing the pressure.
Therefore, the pressure of a gas can be decreased by decreasing its no. of molecules or no. of particles.
<u>AREA OF OBJECT:</u>
The pressure is given by the formula:
where,
A = Area of Object
Therefore, the pressure of a gas can be decreased by increasing area of object.
So, the correct option is:
<u>Decrease the number of gas particles, increase the object's area, and reduce the temperature of the gas</u>
