Answer:
the ratio of the kinetic energy of an electron to that of a proton if their wavelengths are equal is 1835.16 .
Explanation:
We know, wavelength is expressed in terms of Kinetic Energy by :
Therefore , 
It is given that both electron and proton have same wavelength.
Therefore,
.... equation 1.
.... equation 2.
Now, dividing equation 1 by 2 .
We get ,
Putting value of mass of electron = 
and mass of proton = 
We get :
Hence , this is the required solution.
Answer:
true
Explanation:
the sun warms the atmosphere and warms the air which drives our weather
Answer:
The earth's pull on the moon
Explanation:
Earth exerts a gravitational pull on the moon 80 times stronger than the moon's pull on the Earth.
The solution for the problem is:
The pressure of a column of fluid = rho g h
Where: rho = density,
g = 9.81m/s/s, and
h = depth
at 10.92km:
P = 1027kg * 9.81m/s/s * 10920 m
= 1027 kg x 107125.2
= 1.10 x 10^8 Pa (the MKS unit of pressure)
