Answer:
E = 0.4 kWh
Explanation:
Given that,
The power of a bulb, P = 40 W
Time, t = 10 hours
We need to find the energy used by the bulb. Let it is equal to E. So,
So, 0.4 kWh of energy would be needed.

Answer:
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.
