Some microbes can use gaseous N2 as an ingredient to make _______

Looking at a bacterium under a microscope and seeing that it is gram positive and had a cocci shape would mainly tell you about its ______

If you expose a bacterium accustomed to living in the human body to a high-salt environment such as 30% (OR a solution with an extremely high sugar concentration), this would be a ______ environment. 

A very small ball containing a charge -Q hangs from a light string between two vertical charged plates, as shown in the figure. When released from rest, the ball will;  

In the figure, each capacitor has C = 4.00 µF and Vab = +28.0 V. Find the following: NOTE: Answer should be in decimals (i.e 3.1×10-6 would be 0.0000031) and include the unit with your answer.   The equivalent capacitor of the system is [capacitance]. The total charge of the system is [charge] The total energy of the system is [energy] The charge on capacitor C1 is [Q1]. The charge on capacitor C2 is [Q2]. The charge on capacitor C3 is [Q3]. The charge on capacitor C4 is [Q4]. The potential difference across capacitor C1 is [V1]. The potential difference across capacitor C2 is [V2]. The potential difference across capacitor C3 is [V3]. The potential difference across capacitor C4 is [V4]. The energy in capacitor C1 is [U1]. The energy in capacitor C2 is [U2]. The energy in capacitor C3 is [U3]. The energy in capacitor C4 is [U4].

In the figure, point P is equidistant from both point charges. At that point;  

The figure below shows an uneven arrangement of electrons “e” and protons “p” on a circular arc of radius r = 2.00 cm with angles θ1 = 30°, θ2 = 50°, θ3 = 30°, θ4 = 20°.  Find the following:   Show on a free body diagram the direction of the electric fields at point c due to the surrounding particles. NOTE: The free body diagram needs to be provided along with your work and uploaded into CANVAS by 7:15PM. Magnitude of the at point c? NOTE: Answer should be in decimals (i.e 3.1×10-6 would be 0.0000031) and include the unit with your answer.[Magnitude] Direction (relative to the positive x-axis) of the net electric field at point c? NOTE: Answer should be in degrees.[Direction]
