At a particular location < 1.6, -2.5, -3.7 > m in the room
there is an electric field E= <3400, 0, 0> N/C. Figure out
where to place a single positive point particle of charge +6 µC in
order to produce this electric field
For a particular location the average net solar radiation is
6.65 MJ m-2d-1, the soil heat flux is
0.1Rn, the atmospheric temperature is 20⁰ C, the water
surface temperature is 18⁰ C, and a pressure gage height of 2 m.
Since this area is rather arid, the dryness coefficient is a little
larger than normal, with a value of 1.33. Determine the open water
evaporation rate in mm/day using the Priestley-Taylor method.
A series circuit has a capacitor of 1.6×10−6 F and an inductor
of 2.5 H. If the initial charge on the capacitor is 0.11×10−6C and
there is no initial current, find the charge Q on the capacitor at
any time t.
Enter an exact answer. Do not use thousands separator in the
answer field.
Enclose arguments of functions in parentheses. For example,
sin(2x).

Problem 21: A uniform stationary ladder of length L = 3.7 m and
mass M = 19 kg leans against a smooth vertical wall, while its
bottom legs rest on a rough horizontal floor. The coefficient of
static friction between floor and ladder is μ = 0.44. The ladder
makes an angle θ = 56° with respect to the floor. A painter of mass
8M stands on the ladder a distance d from its base.

A buffer is made from 3.7 ?? 10?1 M of HC2H3O2 and 2.9 ?? 10?1 M
of NaC2H3O2
a. What is the pH?
b. If you added 3.0 ?? 10?3 moles of NaOH to 0.100 L of buffer
what is the final pH. (assume that any change in volume is
negligible.)
A 3 m by 3 m square footing is sitting 1.6 m below the ground
surface. The anticipated column loads include a moment (M=50 kN.m),
a horizontal force (Qh=40kN, acting in the same direction as the
moment) at the ground surface and a vertical force (Qv=260kN).
Determine the minimum and maximum stress beneath the footing and
draw the stress profile diagram to scale.
A stepladder consists of two sides of equal mass and a length of
3.7 m, and the two sides are connected by a rope fixed 1.2 m from
the bottom of the ladder. When opened, the angle between the two
sides of the ladder is 61°. The ladder stands on a frictionless
horizontal floor.
Determine the tension in the rope T and the reaction
force at the top hinge if the total mass of the ladder is 17 kg.

The particular scale and location of a normal distribution will
depend on the distribution's specific ________________. However,
all normal curves are bell-shaped, and they are _________________
around their means.

A guy named Joe, who is 1.6 meters tall, enters a room in which
someone has placed a large convex mirror with radius of curvature
R equal to 30 meters. The mirror has been cut in half, so
that the axis of the mirror is at ground level. (Figure 1) As Joe
enters the room, he is 5 meters in front of the mirror, but he is
looking the other way, so he fails to see it. When he turns...
