Answer:
Yes is large enough
Explanation:
We need to apply the second Newton's Law to find the solution.
We know that,
And we know as well that
Replacing the aceleration value in the equation force we have,
Substituting our values we have,
The weight of the person is then,
<em>We can conclude that force on the ball is large to lift the ball</em>
Explanation:
Given that,
The mean kinetic energy of the emitted electron,
(a) The relation between the kinetic energy and the De Broglie wavelength is given by :
(b) According to Bragg's law,
n = 1
For nickel,
As the angle made is very small, so such an electron is not useful in a Davisson-Germer type scattering experiment.
The length of the wire is 36 m.
<u>Explanation:</u>
Given, Diameter of sphere = 6 cm
We know that, radius can be found by taking the half in the diameter value. So,
Similarly,
We know the below formulas,
When equating both the equations, we can find length of wire as below, where
The value gets cancelled as common on both sides, we get
The value gets cancelled as common on both sides, we get
