Answer:
Option (a)
Explanation:
We will discard options that don't fit the situation:
Option b: <em>Incorrect </em>since if the driver "hits the gas" then velocity is augmenting and it's not constant.
Option c and d: <em>Incorrect </em>since the situation doesn't give us any information that could be related directly to the terrain or movement direction.
Option a: Correct. At <em>stage 1</em> we can assume the driver was going at constant speed which means acceleration is constantly zero. At <em>stage 2 </em>we can assume the driver augmented speed linearly, this is, with constant positive acceleration. At <em>stage 3 </em>we can assume the driver slowed the speed linearly, with constant negative acceleration.
d. Butane
Explanation:
The question is asking about the chain isomerism of the compounds.
a. Methane - have 1 carbon atom and does not have isomers.
c. Propane - have 3 carbon atoms and does not have isomers.
b. Ethane - have 2 carbon atoms and does not have isomers.
d. Butane - have 5 carbon atoms and does have two isomers.
You may find the structure of the isomers in the attached picture.

Nerves cover every inch of your body and they control the signals your brain picks up from your muscles. If the connection or communication isn't there between the muscles and the nerves, then you won't be able to move your muscles, which include the skeletal muscles.
Answer:
A black hole is a region of space having a gravitational field so intense that no matter or radiation can escape.
Explanation:
Sorry if this isn't what you meant or were looking for.
Answer:
mass=0.50kg
force=25N
acceleration =?
Now,
force=m×a
25=0.50×a
25÷0.50=a
50=a
acceleration =50m/s^2 answer!!!!
hope this may help you!!!!
