The statement about "<span>efficiency compared the output work to the output force" is false. Efficiency can be compared from the input work to the output work.</span>
Two types of mechanical waves: longitudinal<span> waves and </span>transverse<span> waves; the medium movement differs between the two.
</span>In a longitudinal wave the medium particle movement is parallel to the direction of wave propagation; example is sound wave in air.
I<span>n a transverse wave the medium particle movement is perpendicular to the direction of wave propagation; example is mechanical wave on a string.

Answer:
N = 1036 times
Explanation:
The radial probability density of the hydrogen ground state is given by:






N = 1035.57
N = 1036 times
Answer:
a)COP = 1.67
b) W = 300 J
Explanation:
given,
refrigerator removes = 500 J from a cold reservoir
discharge = 800 J to its hot reservoir
a) COP =
COP =
COP = 1.67
b) heat per cycle exhausted to the
W + 500 = 800
W = 800- 500
W = 300 J
