Answer:
Wiping cloth
Explanation:
When the wiping cloth is used to “clean” another surface, it will contaminate it with the bacteria. To avoid bacterial growth on the wiping cloth, a wet wiping cloth must be stored in a proper sanitizing solution between uses. Provide Proper Concentration of. Sanitizing Solution for Wiping Cloths.
wiping cloth cannot be used on a surface where raw meat was cleaned, utensils, plates and other kitchen eating accessories because of it's ability to contact germs and bacteria.
Answer:
a) λ = 1.12 m
b) f = 5.41 Hz
c) v = 154.54 m/s
d) A = 0.22m
e)
Explanation:
You have the following equation for a wave traveling on a cord:
(1)
The general expression for a wave is given by:
(2)
By comparing the equation (1) and (2) you have:
A: amplitude of the wave = 0.22m
k: wave number = 5.6 m^-1
w: angular velocity = 34 rad/s
a) The wavelength is given by substitution in the following expression:
b) The frequency is:
c) The velocity of the wave is:
d) The amplitude is 0.22m
e) To calculate the maximum and minimum speed of the particles you obtain the derivative of the equation of the wave, in time:
cos function has a minimum value -1 and maximum +1. Then, you obtain for maximum and minimum velocity:

So A Negatively Charged Tube Is Brought Near The Neutral Sphere Then It Forces Electron Movement From The Left To The Right Side Of The Sphere. Once Touched By The Ground, The Electrons Leave The Sphere. When The Tube Is Moved Away, There's An Overall Positive Charge Left On The Sphere.</span>
The two aspects of a force do scientists need to measure are magnitude and direction.
Force:
The force is defined as the external effort applied in the form of push or pull to cause the acceleration of a body.
Mathematically it is expressed as the product of mass and acceleration of an object. Then, the standard expression for the force as per Newton's second law is given as,
F = ma
Here,
m is the mass of the body.
a is the magnitude of the acceleration of the body.
Also, force is a vector quantity that has significance for its magnitude as well as the direction. So any sort of scientific analysis regarding the force needs its magnitude along with the direction of application.
Thus, we can conclude that the two aspects of a force do scientists need to measure are magnitude and direction.
