Answer:

[tex]\mu =0.169704 Ns/m^2[/tex]

Explanation:

From the question we are told that

Area of plate[tex]a=1m^2[/tex]

Angle of inclination [tex]\theta=60 \textdegree[/tex]

Velocity [tex]v=0.75m/s[/tex]

Thickness of oil [tex]t=2mm[/tex]

Weight of plate [tex]w=90N[/tex]

Generally the equation for shear force is mathematically given by

[tex]F=mgsin45 \textdegree[/tex]

[tex]F=90sin45 \textdegree[/tex]

[tex]F=63.639N[/tex]

[tex]F=\mu* \frac{v}{t}[/tex]

[tex]F=\mu* \frac{0.75}{2*10^-^3}[/tex]

[tex]\mu* \frac{0.75}{2*10^-^3}=63.639N[/tex]

[tex]\mu =\frac{63.639}{375}[/tex]

Therefore viscosity is given by

[tex]\mu =0.169704 Ns/m^2[/tex]

Answer: A, to inform people of when, how, and why to wash their hands.

The statement on the CDC  poster is meant to to inform people of when, how, and why to wash their hands.

Hand washing is a very important way of stopping the spread of infectious diseases. We saw this especially during the pandemic when there was a wider call for hand washing.

Answer:

B. a piece of paper being torn

Explanation:

A chemical change is one that cannot be reversed. This means the original properties of the substance or object cannot be restored.

If you cook a raw egg, it would turn into a boiled egg (or a poached egg, however it is being cooked). The reaction is irreversible, so you cannot turn the cooked egg back into a raw egg - it is basically impossible to 'uncook' an already cooked egg.

When you toast a piece of bread, it turns into toast. You can't 'untoast' it back into bread. The chemical changes have already occurred and cannot be undone.

If you tear a piece of paper, it is still paper. You are only ripping it, not changing anything about it. You could simply tape the torn bit back to the original bit, or glue it - either way, it is still paper and nothing has occurred to drastically change the physical state of it.

Therefore, B is not a chemical change.

Explanation:

The triple-point of water occurs at 273.16 K (0.01 °C) and a vapor pressure of 0.0060373 atm. At this point water can be solid, liquid and gas. So, option (D) is correct.

phase diagram: a graph that displays the limiting conditions for a substance's solid, liquid, and gaseous phases under changes in pressure, temperature, or another combination of variables, such as solubility and temperature.

The curves in the figure were derived from measurements taken at various pressures and temperatures, and they represent a typical phase diagram for a one-component system (i.e., one made up of a single pure chemical).

The combination of temperature and pressure at which a substance can exist in all three of its states—gas, liquid, and solid—is known as the triple point.

The Kelvin(K), the International System of Units' (SI) fundamental unit of thermodynamic temperature, is defined using the triple point of water. The triple-point of water occurs at 273.16 K (0.01 °C) and a vapor pressure of 0.0060373 atm.

KE = 8887.5 J

Answer:

KE = 8887.5 J

Answer:

In constructive waves, a greater amplitude wave is formed. In destructive waves, a wave with a smaller amplitude is formed. (option A)

Explanation:

Interference is called the superposition or sum of two or more waves. Depending mainly on the wavelengths, amplitudes and the relative distance between them, there are two types of interference: constructive or destructive.

Constructive interference occurs when there are two waves of identical or similar frequency (both have motions equal to an even number of similar wavelengths) and overlap the peak of one with the peak of the other. These effects add together and make a wave of greater amplitude. All of this is possible because the waves were in the same phase in the beginning (in the same position).

Destructive interference occurs in the opposite case to constructive. When the crest of one wave overlaps the valley of the other, they cancel out since they are in different phases when they overlap (they were in different positions). That is, as in the case of constructive waves they were added, in the case of destructive waves they cancel out (subtract).

So, In constructive waves, a greater amplitude wave is formed. In destructive waves, a wave with a smaller amplitude is formed.

Explanation:

Hooke's law is a law of physics that states that the force needed to extend or compress a spring by some distance scales linearly with respect to that distance—that is, Fₛ = kx, where k is a constant factor characteristic of the spring, and x is small compared to the total possible deformation of the spring.

A. The magnets used to lift metal or cars in a salvage/junk yard

Explanation:

An electromagnet  is defined as a type of magnet which are made up of wires in coil shape. Magnetic field in these wires are produced by electric current.

An example of an electromagnet is magnets used to lift metal or cars in a salvage/junk yard because a crane is used in junkyard to lift metal in which crane is attached to a iron disc and when electricity is off, the disc move downwards and placed near required metal and switch on the electricity when disc reaches on metal or cars to be lifted. This electricity generates magnetism in the iron disc and attract metal or cars from the junkyard.

Hence, the correct answer is "A. The magnets used to lift metal or cars in a salvage/junk yard".

Explanation:

Given

Force (F) = 7 N

Displacement (d) = 8 m

work done (W) = ?

We know that

W = F * d

= 7 * 8
