Answer: Bases are slippery.
Explanation:
Bases and acids can be determined by the amount of hydrogen or hydroxide ions in each solution. If a solution has more hydrogen ions than hydroxide ions, it is acidic, whereas if it has more hydroxide ions than hydrogen ions, it is basic.
Using a litmus paper test for a acidic/basic solution, the paper will turn different colors. In an acidic solution, paper will turn red, but in a basic solution, paper will turn blue.
Bases, compared to acids, feel slippery on the skin because they interact with fatty acids on the skin. Comparatively, acids feel sticky.
Acids taste sour. Think of an acid like lemon juice, compared to bases, which taste bitter (blood, for example)
Answer:
The correct option is that both the ends will remain neutral.
Explanation:
As the rod is grounded all of the prolonged charge will be converted to ground so the overall charge on the rod in absence of the charged ball will be equal to zero.Such that the both ends will not bear any charge.

Answer:
Car A has a velocity of 40 km/hr west.
Explanation:
The velocity of an object is a vector quantity. It has both magnitudes as well as direction.
Arrows are used to show direction.
Car A is moving towards west. Car B is moving towards east-south direction. Car C is moving towards South direction. Car E is moving towards North direction.
So, the correct option is (a) i.e. Car A has a velocity of 40 km/hr west.
