Module 5 Section 3 (inperson motivation)

Mechanical Advantage Review Directions: Use the appropriate equation to answer the following questions. All answers should be recorded below or in your engineering design journal. Remember to show all work. 1. A lever has an effort arm that is 8 meters long and the resistance (load) arm that is 5 meters long, how much effort is needed to lift a 200 Newton weight?

LAST DIGIT IS 5, So delta t = 10 Major: Mechanical Engineering   Course: ThermoDynamics

I need GF,CF,CD asap please

1-An example of a physical property is A) the reaction of rubidium with water to form rubidium hydroxide B) the density of boron C) the burning of sulfur to form sulfur dioxide D) the reaction of cesium with oxygen to form cesium superoxide E) the energy content of liquid sodium 2-If you have 600 kJ of heat to spend, and you use it to melt lead, how many % ounce wheel weights (at 200C) can you melt? Note that Lead is NOT measured in troy ounces, but proper ones (16 ounces in a pound), the specific heat of lead is 0.13 J/goC and its melting point is 327.5oC. 3-The written value of 1.0 um means a. 102 m b. 10-2 m c. 106 m d. 10-6 m e. 10-9 m 4-The written value of 1.0 um means a. 102 m b. 10-2 m c. 106 m d. 10-6 m e. 10-9 m 5- Which element has 71 neutrons? a) 222Rn b) 146 Nd c) 159Sm d) 140Ce e) 121Sn 3.9 6- Which of the following is NOT found in the nucleus? a) in b) He c) }H d) -je d) je 7- There are two common ions for gold: Au(1) and Au(III). Which of these would be the Auric ion?…

This is Mechanical Engineering. Please answer with clear work and answers. Thank you

A dust particle is suspended in the air (floating due to a small updraft and its own low mass) when a powerful loudspeaker plays a very low note (2 Hz so it can’t be heard but you can actually see the speaker move!). How will the dust particle move as a result of the speaker 
being turned on? Question 3 options:   A)  The dust particle will move up and down.   B)  The dust particle will be pushed across the room.   C)  The dust particle will move in a circular path.   D)  The dust particle will move side to side.

Can someone help me to solve the following problem showing all work thank you!
