Air drag is the frictional force which is due to air molecules and it is always opposite to the direction of motion
So here direction of air resistance is always opposite to the motion or velocity
Now if Car is travelling then the force on the car due to engine is always in the direction of velocity of car
Because here engine will provide the force to accelerate the car.
So opposite to that motion there is air resistance.
So here correct answer will be
<em>B) The forward force applied by the engine</em>
Answer:
venus
Explanation:
its small and still its the hottest since it has carbon 4 oxide in its atmosphere
(a) The magnitude of the electric field at point 5.5m is 2.35 x 10⁴ N/C.
(b) The magnitude of the electric field at point 2.5m is 5.18 x 10⁴ N/C.
<h3>Electric field at a point on the Gaussian surface</h3>
The magnitude of the electric field at a point on the cylindrical Gaussian surface is calculated as follows;
E = λ/2πε₀r
where;
- λ is linear charge density
- ε₀ is permitivity of free space
- r is the position of the charge
<h3>At a distance of 5.5 m</h3>
<h3>At a distance of 2.5 m</h3>
Thus, the magnitude of the electric field at points of 5.5m is 2.35 x 10⁴ N/C, and the magnitude of the electric field at points of 2.5m is 5.18 x 10⁴ N/C.

B acid + base → water + salt
Explanation:
The best equation that represents a neutralization reaction is:
acid + base → water + salt
In a neutralization reaction, an acid reacts with a base to produce salt and water only.
Here, hydrogen combines with hydroxide to form water.
Titration is usually used to carry out this reaction in the laboratory.
An indicator is added to the base and at end the color of the reaction changes.
At this point the acids have completely been neutralized with the base.
