Time t 0 sees Collar A start at rest and drop at a steady speed of 7 in/s2. Collar B rises with x = 727.5 millimeters constant.
What does the term "acceleration" mean in plain English?Acceleration is the change in speed that occurs quickly. Generally speaking, but not always, acceleration denotes a shift in speed. Even when an object travels in a circular path, its velocity axis is still moving, therefore it keeps gaining speed.
Calculation
a) aB = 240 mm/s² (↓)
aA = - 345 mm/s²
b) For the Block C
v₀ = 130 mm/s
For the Block A
v₀ = - 43.33 mm/s
c) Δx = 727.5 mm
a) For the Block B
v = v₀ + a*t
480 = 0 + a*(2)
aB = 240 mm/s² (↓)
Then we have
3*LA + 4*LB + LC = L
If we apply
d(3*LA + 4*LB + LC)/dt = dL/dt
3*vA + 4*vB + vC = 0
d(3*vA + 4*vB + vC)/dt = d(0)/dt
3*aA + 4*aB + aC = 0
aA = - (4*aB + aC) / 3
aA = - (4*240 mm/s² + 75 mm/s²) / 3
aA = - 345 mm/s²
b) For the Block C
v = v₀ + a*t
v₀ = v – a*t
v₀ = 280 – (75)(2) = 130 mm/s
For the Block A
When t = 2 s
vB = 480 mm/s
vC = 280 mm/s
we use the formula
3*vA + 4*vB + vC = 0
3*vA + 4*(480) + 280 = 0
vA = - 733.33 mm/s
Now, we can apply
v = v₀ + a*t
- 733.33 mm/s = v₀ + (- 345 mm/s2)(2 s)
v₀ = - 43.33 mm/s
c) We can use the equation
Δx = v₀*t + (1/2)*a*t²
Δx = 130*(3) + (1/2)(75)(3)²

RC Charging Circuit
When a voltage source is applied to an RC circuit, the capacitor, C charges up through the resistance, R
The charging of a capacitor is not instant as capacitors have i-v characteristics which depend on time and if a circuit contains both a resistor (R) and a capacitor (C) it will form an RC charging circuit with characteristics that change exponentially over time.
All Electrical or Electronic circuits or systems suffer from some form of “time-delay” between its input and output terminals when either a signal or voltage, continuous, ( DC ) or alternating ( AC ), is applied to it.
This delay is generally known as the circuits time delay or Time Constant which represents the time response of the circuit when an input step voltage or signal is applied. The resultant time constant of any electronic circuit or system will mainly depend upon the reactive components either capacitive or inductive connected to it. Time constant has units of, Tau – τ
When an increasing DC voltage is applied to a discharged Capacitor, the capacitor draws what is called a “charging current” and “charges up”. When this voltage is reduced, the capacitor begins to discharge in the opposite direction. Because capacitors can store electrical energy they act in many ways like small batteries, storing or releasing the energy on their plates as required.
Determine the head loss during backwash for a filter bed consisting of 0.6 m of sand with f = 0.45, 0.4 m gravel, and a pipe lateral under drain with a circular orifice having α = 0.8 and β = 0.05, Vb = 0.8 m/min.
The head loss during backwash for this filter bed is:
HL = (3.70ρVb2)/(2g[αf + β])
where ρ = density of the fluid (typically water), Vb = backwash velocity, g = acceleration due to gravity, α = orifice discharge coefficient, f = bed porosity, and β = orifice area ratio (orifice area / pipe lateral area).
For the given filter bed, the head loss is equal to:
HL = (3.70*1000*(0.8 m/min)^2)/(2*9.81*(0.8*0.45 + 0.05)) = 0.124m
The head loss during backwash is mostly due to friction loss as the water flows through the filter bed and friction loss is caused by the resistance to flow of the bed particles. The orifice is also a source of head loss due to the sudden expansion of the water from the pipe lateral to the orifice.

The 25-kg bar has a center of mass at G. If it is supported by a smooth peg at C, a roller at A, and cord AB, determine the reactions at these supports.
A fixed support that is to a structure restricts all rotations and movements at that location.
There are six support responses applied from the fixed support to the structure since the joint with fixed support has no degrees of freedom. R (externally independent) (externally independent) Support for a There are three possible reactions at a engine. The term "ball and socket joint" is another name for the support. A built structure is often connected to its base using one of three basic types of connections: roller, pinned, and fixed. A simple support is a fourth form that is uncommon in building constructions. This is frequently as having no friction.

n this installation each winding is using tap 5. assuming tap 5 has been selected to correct the incoming supply voltage, which tap choices left can correct for a future voltage increase on the feeder?
Each winding in this installation uses tap 5. To adjust the incoming supply voltage, tap 5 has been chosen. A future rise in feeder voltage can be compensated for by tapping 1 or 2 on the left.
What does voltage mean, exactly?Voltage is the term used to describe the "pressure" that applies to electricity. Voltage is expressed in voltages (V), and higher voltages cause an electrical device to receive more electricity.
What factors determine voltage?Connecting the measurement equipment to the network or element that has to be measured is the conventional approach for evaluating volts (the load). To measure the right power and avoid absorbing any radiation from the circuit being evaluated first, the measuring device must have an endless harmonic distortion (resistance).

14. Which of the following statements correctly defines balance point temperature?
A. The inside temperature at which cooling is required
B. The outside temperature at which point ventilation isn't required
C. The outside temperature at which point heat loss from the building equals internal heat gain
D. The inside temperature at which point backup heat comes on
Answer:
C. The outside temperature at which point heat loss from the building equals internal heat gain
Explanation:
The balance point temperature (also known as "balance temperature" or "neutral temperature") is the outside temperature at which the heat loss from a building equals the internal heat gain. At this point, no heating or cooling is required to maintain a comfortable indoor temperature. The balance point temperature is used in building design and HVAC system design to determine the appropriate size and type of heating and cooling equipment needed for a building.
dry air will break down if the electric field exceeds about 3.0×106v/m.What amount of charge can be placed on a capacitor if the area of each plate is 8.8 cm^2?
If the electric field surpasses 3.0106v/m, dry air will degrade. If a capacitor's plates have an area of 8.8 cm2 apiece, it can hold a charge of 23.364 nC.
The charge of the capacitor is
Q=CV
= (ε₀A/d)(Ed)
Q=ε₀EA
The amount of charge that can be placed on a capacitor is,
Q=ε₀EA
=(8.85×10⁻¹²Nm²/C²)(3×10⁶ V/m)(8.8×10⁻⁴ m²)
=23.364×10⁻⁹
= 23.364 nC
The electric field is mathematically defined as a vector field that can be associated with each point in space, representing the force per unit charge exerted on a positive test charge at rest at that point.
The electric charge or time-varying magnetic fields produce the electric field. The electric field is responsible for the attractive forces that hold the atomic nucleus and electrons together at the atomic scale.
Gauss' law states that the total electric flux out of a closed surface is equal to the charge enclosed divided by permittivity. Or, the total flux associated with a surface is one-tenth of the charge enclosed by the closed surface.
