The 100% relative humidity in the winter feel nothing like 100% in summer because it depends on "the saturation of the temperature".
<u>Explanation:</u>
Temperature really makes a big difference. Even once warm, a cold winter air produces much less humidity than summer heat. One cubic unit of air needs 0.001 ounces of water to saturate it, to elevate its ratio to one hundred per cent.
Nevertheless, it takes 0.022 ounces of water to saturate the one cubic unit of air once the temperature is eighty, which is twenty-two times that amount of water. Air with a humidity of one hundred percent at eighty degrees holds twenty-two times as much water as air at zero with humidity at one hundred percent.
Answer:
B) 89500 km
Explanation:
speed = distance / time
time= 3h 58 min = 30+58/60= 30.966 h = 31 hrs (approxx)
250= distance / 31
250× 31= distance
distance = 7750 ( approxx)
but none of the given options is 7750 km so we will choose the answer nearest to it,
therefore 89500km is the right answer
Answer: in this question, the only charge in the cavity is Q. Inside the conducting spherical shell, the electric field is zero.
While outside the shell, the electric field is given by: k(q + Q)/r²
Where;
K= is a constant which is given as, 8.99 x 10^9 N m² / C².
Q= source charge which creates the electric field
q= is the test charge which is used to measure the strength of the electric field at a given location.
r= is the radius
Explanation: Inside the conducting spherical shell, the electric field is zero since the Electric field vanishes everywhere inside the volume of a good conductor.
