An object which experiences either a change in the magnitude or the direction of the velocity vector can be said to be accelerating. This explains why an object moving in a circle at constant speed can be said to accelerate - the direction of the velocity changes.

Answer:

This question is incomplete but the complete question is below

  • Which of the following does not change when a car keeps a constant speed, but changes direction?

a.Acceleration

b.Velocity

c.Momentum

d.Mass

The correct option is d

Explanation:

This question seeks to test the knowledge of the two types of quantity we have in physics; scaler and vector quantities.

A scaler quantity is a quantity that has a magnitude (or numerical value) but no direction while a vector quantity is a quantity that has both magnitude and direction.

The question is obviously asking after a scaler quantity because a value that does not change when affected by direction as stated earlier is a scaler quantity. Acceleration, velocity and momentum are all vector quantities as they are affected by both magnitude and direction but mass remains constant irrespective of direction. Hence, the answer is option d (mass).

The equilibrium reaction, causes the water dissociation constant, Kw, is 1.01 × 10-14<span> at 25 °C. That is because every H</span>+<span> (H</span>3O+) ion these forms accompanied by the formation of an OH-<span> ion, are the concentrations of these ions and in pure water the same thing can be calculated from </span>Kw<span>.

RSB [31]

A magnet creates an invisible area of magnetism all around it called a magnetic field. The north pole of a magnet points roughly toward Earth's north pole and vice-versa. That's because Earth itself contains magnetic materials and behaves like a gigantic magnet
