The awnser would be D the tilt on the earth on its axis
Answer:
66.7m/s²
Explanation:
initial velocity(V)=54m/s
Final velocity(U)=4m/s²
Time taken(t)= 0.75 seconds
Acceleration is unknown
To find the acceleration we use this formula
a=v-u/t
a=54-4/0.75
a=50/0.75
a=66.666666
since it is acceleration we use the symbol m/s² after approximating to 1 decimal place
a=66.7m/s²

Explanation:
There are multiple characteristic that all dinosaurs shared. Some of the synapomorphies include:
- Vertebrates; skeletons with back bones that surrounds a nerve cord.
- Amniotes; specially adapted for life on dry land.
- Diapsids; two holes located above and behind the eye sockets on each side of the skull.
- Archosaurs; antrobital ferestra, a hole between the nasal hole and the eye socket hole.
But still all of this doesn't separate them from all others, what is unique to them is that all of the 'true dinosaurs' were land dwellers.
Answer:
THE EQUILIBRIUM CONSTANT EXPRESSION Kc = ![\frac{[C2H5OH]}{[C2H5OC2H5]}](https://tex.z-dn.net/?f=%5Cfrac%7B%5BC2H5OH%5D%7D%7B%5BC2H5OC2H5%5D%7D)
Explanation:
The equilibrium constant, Kc is an expression given by the ratio of the concentrations of the products over the reactants. TN.B: the activities of pure solids and liquids are equal to 1.
Kc = ![\frac{[products]^n}{[reactants]^n}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Bproducts%5D%5En%7D%7B%5Breactants%5D%5En%7D)
where n= no of moles
Reaction equation:
2C2H5OH 
→ C2H5OC2H5
⇒ Kc = ![\frac{[C2H5OC2H5] [H2)]}{[C2H5OH]^2}](https://tex.z-dn.net/?f=%5Cfrac%7B%5BC2H5OC2H5%5D%20%5BH2%29%5D%7D%7B%5BC2H5OH%5D%5E2%7D)
but [H20] = 1
∴ Kc =
