Answer:
Required answer = 2.7 x 10^16 MOLECULES
Explanation:
We know that
1 m = 100 cm
so 1 m^3 = (100 cm)^3 = 1000000 cm^3 = 1 x 10^6 cm3
as per question, 2.7*10^{10} molecules in 1 cm^3
so number of molecules in 1 m^3
Number of molecules = ( 2.7 x 10^10 molecules /1 cm^3 ) x ( 1 x 10^6 cm3 / 1 m3)
Number of molecules = 2.7 x 10^10 x 1 x 10^6 = 2.7 x 10^16 per m3
Required answer = 2.7 x 10^16 MOLECULES
They depend on it because this helps them maintain nutirance and survive and reproduce more.
... the angular tilt of the Earth's position on its axis relative to the sun
Explanation:
One way of classifying stars is by their temperature .
or
Science strives to be able to describe how stars and planets form and evolve. This requires theories to describe the processes which include:
Star and planet formation
Star and planet composition
Stellar and solar system evolution
The nuclear processes happening inside stars
The scientific method means that all theories are put to the test. By measuring or calculating the temperature, age and composition of other planets and stars the theories can be tested. If observed values of these parameters are not predicted by theories, then the theories are wrong and need to be revised or replaced.
Answer:
-0.01 mm
Explanation:
We are given that
The value of one division of vernier scale =0.5 mm
The value of one main scale division=0.49 mm
We have to find the value of least count of the instrument in mm.
We know that
Leas count of vernier caliper=1 main scale division-1 vernier scale division
Least count of vernier caliper=0.49-0.50=-0.01 mm
Hence, the least count of the instrument=-0.01 mm
Answer: -0.01 mm
