Answer:
Only 9% weaker
Explanation:
Because this is where most stuff that people do in space takes place. So, um, here we're at a radius of the earth plus 300 kilometers. You may already be seeing why this isn't going to have much effect if this were except the 6.68 times, 10 to the sixth meters. And so the value of Gout here. You know, Newton's gravitational constant times, the mass of the Earth divided by R squared for the location we're looking at. And so this works out to be 8.924 meters per second squared, which is certainly less than it is at the surface of the earth. However, this is only 9% less than acceleration for gravity at the surface. So the decrease in the gravity gravitational acceleration of nine percent not really going toe produces a sensation of weightlessness.
Bandwidth is the difference between the upper and lower frequencies in a continuous band of frequencies.
Mathematically can be expressed as,
The upper frequency is 88Hz and the lower frequency is 6, therefore the Bandwidth would be,
The center frequency is given on the basis of the square root of the multiplication of the two reference frequencies, then,
Answer: To collect and remove wastes from the body.
Explanation:
The excretory system helps to collect and remove wastes from the body in the form of urine.
Answer: b- covection
Explanation:
Conduction: It is the circulation or transfer of heat through a metal or solid. For example, heat generated inside an enclosure can be transferred to the outer surface by means of conduction.so therefore conduction can not be the answer.
Convection is the circulation or tansfer of heat from a surface by means of a fluid such as air. Natural convection happens when air is heated: it expands, rises, and is replaced by cooler air. The amount of convection may be increased by using a fan to increase the flow of air.Likewise,Ducts are used to circulate air in the system. Since, air is circulated in the system, heat is transfered by convection.Hence,the answer is B-convection.
Radiation: Here, energy is radiated through the air by means of electromagnetic radiation. Since heat transfer through raidation does not involve contact between the heated object and the heated source,so energy is lost as light or through electromagnetic radiation. So C is wrong.
