Answer:
λ = 1.2 x 10⁻⁶ m
Explanation:
Given that,
slit separation, d = 0.050 mm
= 5 x 10⁻⁵ m
Distance between the fringes, D = 5.00 m
distance between the fringes, x = 12.0 cm
= 0.12 m
wavelength of the light = ?
the separation between the fringe is given by
where as n = 1
λ = 1.2 x 10⁻⁶ m
A. At the top. At this point, the child is highest, and they are not moving. Their potential energy is much greater.
How fast they are falling
Answer:
The false statement is 'Electric field lines form closed loops'.
Explanation:
- Electric field lines originate from positive end and terminates at negative end,i.e., field lines are inward in direction to the negative charges and outward from the positive charges.
- These lines when close together represents high intensity and when far apart shows low intensity of the field.
- These lines do not intersect, as the tangent drawn on these lines provides us with the field direction and intersection of these lines means two field directions which is not possible.
- These lines unlike magnetic field lines do not form closed loops as they do not turn around but originate at positive end and terminates at negative end which ensures no loop formation.
Answer:
B. The same as that for container A
Explanation:
To calculate the average Kinetic Energy per molecule,
Where is the average kinetic energy per molecule and is the Boltzmann constant
From the above equation it is seen that only depends on the temperature of the gas
And since the temperatures of both gases are equal, their average kinetic energy per molecule is the same
