Because it tends to be hotter inside therefore when the cold air hits the inside of the glass, the cold glass makes it condense however outside its cold therefore it does condense on the outside of the window
Answer:
102 km/h
Explanation:
x = distance of car A at any time from the intersection
x₀ = distance of car A at some time = 0.4 km
= Speed of car A = 75 km/h
y = distance of car B at any time from the intersection
y₀ = distance of car B at some time = 0.3 km
= Speed of car B = 70 km/h
d = distance between the two cars at any time
d₀ = distance between the two cars at some time
v = rate of change of distance between the cars
Using Pythagorean theorem
d²₀ = x₀² + y₀²
d²₀ = 0.4² + 0.3²
d₀ = 0.5 m
Distance between the two cars at any time is given using Pythagorean theorem as
d² = x² + y²
Taking derivative both side relative to "t"
(0.5) v = (0.4) + (0.3)
(0.5) v = (0.4) (75) + (0.3) (70)
v = 102 km/h
A falling object (directly downward) is slowed down by air resistance. In turn it would take longer to fall.
Answer:
New research reveals that glycans -- branched sugar molecules found in mucus -- can prevent bacteria from communicating with each other and forming infectious biofilms, effectively rendering the microbes harmless.
Explanation:
It depends what is the position of earth and saturn. Distance from earth to saturn varies depending on whether earth is between sun and saturn or sun is between earth and saturn. Obviously, the shortest distance will be if earth is between sun and saturn. we will take that the distance between earth and saturn is:
s = 1 275 000 000 km
The time required to travel that distance is:
t = s/v = 45535 hours or 1897.3 days
