Answer: b. Salt lakes are formed when river bends are cut off.
Salt lakes are formed when water from water sourced gets accumulated in a shallow region and the supply of water is cut. These salt lakes are terminal which means water does not flow to other locations. Therefore, salt lakes are formed when river bends are cut off.

Internal thermal energy is given as
so it will depend on the product of mass, specific heat capacity and temperature.
so here we know that both blocks are identical with same initial temperature
So the block with larger mass must have more internal energy
So here the correct answer would be the block with mass 1000g
block with mass 1000 g must have more internal energy
Angular width is 3 x 10^-3
Let D be the distance between source and screed d the distance between coherent source then for central diffraction maxima,
where λ is wavelength
Given:
λ = 450 nm = 450×10^−9m
d = 0.3x10^−3m, D = 1m
W = 2 x 450×10^−9/0.3x10^−3*1
To Find:
Angular width
Solution: The width of the central maxima is nothing but the difference between the positions of the first two minima. Hence we will use the expression for the position of minima and accordingly obtain the expression of the width of central maxima and secondary maxima
θ = W/D
θ = 2 x 450×10^−9/0.3x10^−3*1/1 = 3 x 10^-3
Hence, angular width is 3 x 10^-3

<span>Since youc oncetrate all your force directly towards the moment arm it means that you push it at an angle of your force is directed to the left or the right and I bet that it must be 90</span> degrees to the bar. Obviuosly, if you are about to push it you will do it straight up but not in a zig zag way. In other words, it should be perpendicular to the arm because the<span> torque can be produced only if force is applied at a constant index (90).
Hope that helps! Regards.</span>
