If matter has a wave nature, why is this wave-like characteristic not observable in our daily experiences?

Due to the large mass of the objects, we can not observe wave-like characteristics in daily life.

Explanation:

The wavelength of De-Broglie is given by the relation:

Here, h is Planks constant, m is the mass of electron, v is the velocity.

The Plank’s constant value is very small,so the wavelength which is  associated with ordinary object is very small and it is very difficult to observe in our daily life.

In daily life  we observe the objects posses the larger mass and much smaller velocity,that is why the wave nature of these large objects is not more common in day to day life.

But for the small objects like  neutrons and electrons, the wave behavior of particle is dominating .It is because of the reason that mass of neutron and electron are very small in comparision with the ordinary tennis ball.

answer: a ball

explanation: because it will bounce

the simple machine has three main features. they are:

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.

the keisha 's machine labels are

x : load

y: fulcrum

z: lever
