Draw a free-body diagram for the ear of a person properly wearing a mask. You may wish to refer to the figure below to aid you. Note that when properly worn, the mask will pull at an angle below the horizontal. Improper
usage, such as shown in the image on the right, may result in a completely horizontal pull (the arrows in the figure
are not force arrows), but we wish to avoid this. Choose your own labels for the forces but use the angle the
mask force makes with the horizontal.
Include your free-body diagram in your reply. Also, using the math editor, write the component equations of
equilibrium relative to vertical and horizontal axes. Use the labels for your forces, as well as the angle. You may
substitute for the force of gravity, using the mass of the ear.

Ok i am attempting to my niece attach a galvanized wire (like a tether for a dog) at the corner of two fences, making a tightwire if you will and we drilled a hole in a softball and she hits it. the ? and problem is that we can not get the wire taunt enough where it doesnt sag after hitting the ball once, and the wire sags and wobbbles. its a 15 ft rubber covered galvanized wire and one can adjust the length of the placing of the wire by having it make the corner of 2 fences become a it can be adjusted, however, with all our human strength and pliers we could not make it taunt as possible. is there anything other that attaching it to a car to do this. sorry abt the length but it would mean the world to my niece if i could solve this came up with the entire idea herself, and she is 14 and paid for the wire and did as much work as i did drilling a hole through a softball wide enough for attaching piece at each end of the wire that clips on to the fence. . any ideas welcome if serious. but awesome if it is a fact. much obliged. bucky bukowski buckman

The specific heat of silver is 0.057 calories/gram°c. if 10.0 grams of silver were heated and the temperature of the sample changed by 20.0°c, how many calories of heat energy were absorbed by the sample?
