Answer:
Scientific knowledge is used to create new technologies. New technologies often allow scientists to explore nature in different ways and make new discoveries.
Explanation:
That they sometimes explode?
Answer:
Is always towards the center of the Earth
Explanation:
As a satellite moves around the Earth in a circular orbit, the direction of the force of gravity is always towards the center of the Earth. At an altitude of 100 km, you would be so high that you would see black sky and stars if you looked upwards.
Answer:
change in height is 1.664 mm
Explanation:
Given data
drops = 3.00 mm
diameter = 5.00 cm = 0.05 mm
decrease = 350 cm^3
temperature = 95°C to 44.0°C
to find out
the decrease in millimeters in level
solution
we will calculate here change in volume so we can find how much level is decrease
change in volume = β v change in temp ...............1
here change in volume = area× height
so =
/4 × d² h
so we can say change in volume =
/4 × d² × change in height .......2
so from equation 1 and 2 we calculate change in height
( β(w) -β(g) )× v× change in temp =
/4 × d² × change in height
change in height = 4 × ( β(w) -β(g) ) v× change in temp /
/4 × d²
put all value here
change in height = 4 × ( 210 - 27 )(350 )
× (95-44) /
/4 × 0.05²
change in height is 1.664 mm
C. sulfur dioxide, carbon dioxide, and
nitrogen oxides
These three chemical compounds play a
role in the chemistry of acid rain or acid precipitation. These compounds are
then in the process as they evaporate are converted into acids, mainly, nitric
acid and sulfuric acid. These toxic gases that composes acid precipitation is
actually caused by industries, factories or plants that utilizes such chemicals
and then uses a humongous amount which then is released in during the process
of certain products or manufactured objects.
