Average acceleration is calculated using the equation V(f)-V(i) / t(f)-t(i). (Final velocity minus initial velocity divided by final time minus initial time)
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
Answer:
In one rotation, the large wheel turns 4m.
Explanation:
The given values are:
Input distance,
= 0.64 m
Mechanical advantage,
= 0.16
As we know,
⇒ 
On putting the values, we get
⇒

Hydrogen has one electron in its outermost shell, while fluorine has seven electron in its outermost shell, hence both hydrogen and fluorine needs a single electron to complete its outermost shell.
That's why there is a single bond between hydrogen and fluorine.
Hence both hydrogen and fluorine share one electron with each other, so option "A" is correct.
