Answer:
Explanation:
i'm not sure but i think it might be b.
Answer:
Because it unites particle and wave nature.
Explanation:
De Broglie wavelength can be defined as the,
Here, h is planks constant, m is the mass of electron, v is the velocity of electron.
Since the de Broglie wavelength can behave like the photon wavelength with respect to the momentum
It unites particles and waves nature ,so De Broglie wavelengths is probability waves associated with the wave function according to physicists.
it will be very hot so that causes nobody to walk on venus because its the hottest outer planet.
hope I helped :)
Answer:
Part a)
Part b)
Part c)
Part d)
from t = 0 to t = 4.9 s
so the reading of the scale will be same as that of weight of the block
Then its speed will reduce to zero in next 3.2 s
from t = 4.9 to t = 8.1 s
The reading of the scale will be less than the actual mass
Explanation:
Part a)
When elevator is ascending with constant speed then we will have
So it will read same as that of the mass
Part b)
When elevator is decending with constant speed then we will have
So it will read same as that of the mass
Part c)
When elevator is ascending with constant speed 39 m/s and acceleration 10 m/s/s then we will have
Reading is given as
Part d)
Here the speed of the elevator is constant initially
from t = 0 to t = 4.9 s
so the reading of the scale will be same as that of weight of the block
Then its speed will reduce to zero in next 3.2 s
from t = 4.9 to t = 8.1 s
The reading of the scale will be less than the actual mass
C because mass is how much space an object takes up
