As the speed of the plunger increases, the wavelength of the waves decreases. The greater the frequency, the smaller the wavelength. The smaller the frequency, the greater the wavelength. When we increase the speed of the plunger, the frequency of the waves also increases, and just like with the size of the ball, it’s the speed of the plunger and the frequency of the waves are directly related.
Answer:
false
Explanation:
it cant defined the messy and clean states
V^2 = 700J/0.5*35kg
V = square root of 40
v = 6.324 m/s
Answer:
The dimension is L
Explanation:
Dimension analysis is a method of representing quantities majorly with respect to some fundamental quantities of mass (M), length (L), time (T).
A sphere has a definite volume which relates to its radius by:
V = ![\frac{4}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B3%7D)
![\pi](https://tex.z-dn.net/?f=%5Cpi)
![r^{3}](https://tex.z-dn.net/?f=r%5E%7B3%7D)
In this equation
is a dimensionless quantity, and the unit of v is
.
But, metre is a measure of length, thus it has a dimension of L.
So that,
≅ ![L^{3}](https://tex.z-dn.net/?f=L%5E%7B3%7D)
Then,
= ![r^{3}](https://tex.z-dn.net/?f=r%5E%7B3%7D)
Find the cube root of both sides to have,
r = L
Therefore, the dimension of the radius of a sphere is L.
Answer:
21
Explanation:
Weight on the moon is 16.5 % of weight on earth
Weight on moon = 0.165 * 130
Weight on moon = 21 lbs
