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.

Aballoon is rising vertically upwards at a velocity of 10m/s. when it is at a height of 45m from the ground, a parachute bails out from it. after 3s he opens his parachute and decelerates ata a constant rate 5m/s.when. (a) what was the height of the parachutist above the ground when he opened his parachute? (b)how far is the parachutist from the balloon at t=3s? (c)with what velocity does the parachutist hit the ground? (d)after how long does the parachutist hit the ground after his exist from the balloon?

Calculate the minimum energy required to remove one proton from the nucleus 126c. this is called the proton-removal energy. (hint: find the difference between the mass of a 126c nucleus and the mass of a proton plus the mass of the nucleus formed when a proton is removed from 126c.) express your answer with the appropriate units. emin e m i n = nothing nothing request answer part b how does the proton-removal energy for 126c compare to the binding energy per nucleon for 126c, calculated using eb=(zmh+nmn−azm)c2?
