Answer:
carbon has four unpaired electrons in its valence shell . hydrogen having one unpaired electron in its valence shell comes to bond with carbon by sharing a pair of electrons .since carbon needs 4 electrons to be stable, 4 hydrogen atoms take part in the bond . It's a covalent bond because the difference between the electronegativity of carbon and hydrogen is quite small .
Answer:
3 meters per second
Explanation:
72 divided by 3= 24 meters in 8 seconds
24/8= 3, so 3 meters per second
Explanation:
D . Radian is not a fundamental S.I unit
U = 6.5 m/s, initial speed
t = 3.6 s, time
a = 0.92 m/s², acceleration
Let v = the final velocity.
Then
v = u +at
v = (6.5 m/s) + (0.92 m/s²)*(3.6 s) = 9.812 m/s
Answer: 9.81 m/s
