<span>Fields surrounding a stationary charge produces an electric field and fields surrounding a smoving charge produces a magnetic field and this magnetic field force cant perform any work because it is perpendicular to the field(B) and velocity(V) but electric field force can perform work</span>
The answer is: Yes, the car is accelerating because it is changing direction as it goes around the curve.
- Because the direction of motion of an object even if the object is maintaining a constant speed still count as acceleration.
- Acceleration is a change in velocity, either in its magnitude i.e speed or in its direction or both.
- So, In a uniform circular motion, the direction of the velocity changes constantly, So there is always an associated acceleration, even though the speed might be constant.
-So when you go around a sharp curve if you hold the wheel steady during a turn and move at constant speed, you are in uniform circular motion. What you notice is a sideways acceleration because you and the car are changing direction.
Answer:
Ok, so the goal of a titration is to figure out the concentration of the NaOH solution by seeing how much acid it takes to neutralize the NaOH solution. NaOH is a base, you want to neutralize it with an acid. The best acids to use would be a strong acid.
Some good choices would be hydrochloric acid, hydrobromic acid, hydroiodic acid, perchloric acid, nitric acid, or sulfuric acid. In reality, though, you could use pretty much any acid you wanted to.
Oh, and you should probably also add an indicator to your solution so that you know when your titration is done. In this case, a good choice would be phenolphthalein because it changes color right about pH of 8.
