AWhich of the following would most likely cause a decrease in the quantity supplied? A decrease in price.
Answer:
The coefficient of static friction between the box and floor is, μ = 0.061
Explanation:
Given data,
The mass of the box, m = 50 kg
The force exerted by the person, F = 50 N
The time period of motion, t = 10 s
The frictional force acting on the box, f = 30 N
The normal force on the box, η = mg
= 50 x 9.8
= 490 N
The coefficient of friction,
μ = f/ η
= 30 / 490
= 0.061
Hence, the coefficient of static friction between the box and floor is, μ = 0.061
Answer:
A.![1900 kg/m^3](https://tex.z-dn.net/?f=1900%20kg%2Fm%5E3)
Explanation:
We are given that
![m=8.6 kg](https://tex.z-dn.net/?f=m%3D8.6%20kg)
Density,![\rho_s=3400 kg/m^3](https://tex.z-dn.net/?f=%5Crho_s%3D3400%20kg%2Fm%5E3)
Tension,T=38 N
We have to find the density of liquid.
![T=mg-\rho_l Vg](https://tex.z-dn.net/?f=T%3Dmg-%5Crho_l%20Vg)
![g=9.8 m/s^2](https://tex.z-dn.net/?f=g%3D9.8%20m%2Fs%5E2)
Volume,V=![\frac{m}{\rho_s}](https://tex.z-dn.net/?f=%5Cfrac%7Bm%7D%7B%5Crho_s%7D)
![38=8.6\times 9.8-\rho_l\times \frac{8.6}{3400}\times 9.8](https://tex.z-dn.net/?f=38%3D8.6%5Ctimes%209.8-%5Crho_l%5Ctimes%20%5Cfrac%7B8.6%7D%7B3400%7D%5Ctimes%209.8)
![\rho_l\times \frac{8.6}{3400}\times 9.8=8.6\times 9.8-38](https://tex.z-dn.net/?f=%5Crho_l%5Ctimes%20%5Cfrac%7B8.6%7D%7B3400%7D%5Ctimes%209.8%3D8.6%5Ctimes%209.8-38)
![\rho_l=\frac{(8.6\times 9.8-38)\times 3400}{8.6\times 9.8}](https://tex.z-dn.net/?f=%5Crho_l%3D%5Cfrac%7B%288.6%5Ctimes%209.8-38%29%5Ctimes%203400%7D%7B8.6%5Ctimes%209.8%7D)
![\rho_l=1867kg/m^3\approx 1900 kg/m^3](https://tex.z-dn.net/?f=%5Crho_l%3D1867kg%2Fm%5E3%5Capprox%201900%20kg%2Fm%5E3)
Option A is true.
The "El-nino current is awarm current that periodically flows southward along the coast of Ecuador and Peru. El-nino start out from the central and east central of the pacific, which include pacific coast of this south America. this ocean event is associated with fluctuation of inter tropical surface pressure pattern and circulation in the ocean.
No you can’t because north and south attract eachother
