The multimeter used on PV equipment should be true RMS types capable of measuring at least 600 volts AC or DC.
This is based on the voltage readings capacity of the multimeter. The multimeter for measuring AC and DC volts usually comes with between 120-, 240-, 480-, 600- volts AC and 125-, 250-, 600-volts DC.
A multimeter is a common electronic instrument often used by technicians and engineers. It is either in analog or digital form. It is used for measuring any of the voltage, current, and resistance.
Hence, in this case, it is concluded that the correct answer is 600 voltages.

What does the line strung between the batter boards represent?
Batter boards (or battre boards, Sometimes mispronounced as "battle boads") are temporary frames, set beyond the corners of a planned foundation at precise elevations. These batter boards are then used to hold layout lines (construction twine) to indicate the limits (edges and corners) of the foundation.

Answer:
see attached for a diagram and loads
Explanation:
The mass of the man represents a downward force of ...
F = ma
F = (85 kg)(9.8 m/s²) = 833 N
at a point 1.5 meters from one support. In the attached diagram, the man is standing left of center, so is 1.5 m from the left support, and 4.9 m from the right support.
The mass of the beam represents a downward force of ...
F = (15 kg)(9.8 m/s²) = 147 N
This is effectively modeled by a force acting on the center of the beam, 3.2 m from each support. The distance between supports is 6.8 -2(0.2) = 6.4 m.
The net torque on the beam is zero. This means we can sum the torques at either support and set them to zero. If we let s1 represent the upward force supplied by the left pillar, and s2 the upward force supplied by the right pillar, the two torque equations are ...
torque = force × distance
CW torque about the left pillar: 833×1.5 +147×3.2 -s2×6.4 = 0
s2 = 1719.9/6.4 ≈ 268.7 . . . newtons
CCW torque about the right pillar: -s1×6.4 +833×4.9 +147×3.2 = 0
s1 = 4552.1/6.4 ≈ 711.3 . . . newtons
The magnitudes of the loads carried by the supports are 268.7 N and 711.3 N.
__
Check
For static equilibrium, the sum of upward forces must match the sum of downward forces:
268.7 +711.3 = 980 . . . . newtons (total of upward forces)
883 +147 = 980 . . . . . . . newtons (total of downward forces)

a burglar's car had a start with an acceleration of 2m/s . A police vigilant party cane after 5seconds and continued to chase the burglar's car with a uniform velocity of 20m/s . find the time taken in which the police van will overtake the burglar's car
Explanation:
Let the distance covered after which the police party catches the burglar is ‘s ’.
Let ‘t ’ be the time and given that the police came after 5sec, therefore the time taken by police to catch the burglar is ‘t−5 ’.
The burglar’s car will start moving from rest, therefore initial velocity is, u=0
Given that the acceleration is 2m/s
Applying the equation of motion,
S1=ut+12at2
⇒S1=0×t+12×2×t2
⇒S1=0×t+12×2×t2
⇒S1=t2 -----------(i)
Since the police’s car is moving at uniform velocity, therefore acceleration will be =0, Also u=20m/s.
Again applying the equation of motion to the police car,
⇒S2=ut+12at2
On substituting the corresponding values, we get
⇒S2=20(t−5)+12×0×t2
⇒S2=20t−100 -------(ii)
Since the time at which the police car catches the burglar’s car is to be calculated, therefore
S1=S2
⇒t2=2t−100
⇒t2−20t+100=0
we can rewrite the above equation as,
⇒(t−10)2=0
⇒(t−10)(t−10)=0
On solving,
⇒t=10
The time taken by the police is t−5=10−5=5sec.
hope this helps you.

two technicians are describing how an air-conditioning system gets rid of the heat. Technician A says that heat always flows from the hotter to the colder object. Technician B says that as refrigerant evaporates, it absorbs heat as it changes from a liquid to a gas. which technician is correct?
Based on the information provided by these technicians, both of them are correct.
How does heat flow?According to heating, ventilation, and air conditioning (HVAC), heat in an air-conditioning system generally flows from the hotter object to the colder object.
As the refrigerant evaporates in a small radiator-type unit (evaporator), it absorbs heat as it changes phase from liquid to gas. Also, as the heat is being absorbed by the refrigerant, the small radiator-type unit (evaporator) becomes cold.
In conclusion, we can logically deduce that both of them are correct.

Liquid water flows isothermally at 20°C through a one-inlet, one-exit duct operating at steady state. The duct’s inlet and exit diameters are 0.02 m and 0.1 m, respectively. At the inlet, the velocity is 10 m/s and pressure is 1 bar. At the exit, determine the mass flow rate, in kg/s, and velocity, in m/s.
The continuity equation allows finding the results for the speed and flow of the outlet pipe are:
Q = 3.14 kg / s v₂ = 0.4 m / s
Fluid mechanics studies the movement and fluid dynamics, it is described by two fundamental relationships:
The Bernoulli equation that an expression of the energy conservation[tex]P_1 + \frac{1}{2} \rho v_1^2 + \rho g y_1 = P_2 + \frac{1}{2} \rho v_2^2 + \rho g y_2[/tex]
Where P is the pressure, v the velocity, y the height, the subscripts are two selected points of interest in the pipe.
The continuity equation which is an expression that our principle of mass conservation for fluids
[tex]A_1v_1 = A_2 v_2[/tex]
Where A₁ and A₂ is the area of the inlet and outlet pipes and v₁ and v₂ are the velocities of the fluid at the inlet and outlet
They indicate the inlet and outlet diameters of the pipe are d₁ = 0.02 m and d₂ = 0.1 m, the inlet velocity v₁ = 10 m / s, with the continuity equation let's find the outlet velocity
[tex]v_2 = ( \frac{A_1}{A_2} )^2 \ v_1[/tex]
the cross section of the tavern is
A = [tex]\pi r^2 = \pi \ d^2/4[/tex]
Where r is the radius and d is the diameter
Let's substitutes
[tex]v_2 = (\frac{d_1}{d_2} )^2 \ v_1[/tex]
[tex]v_2 = (\frac{0.02}{0.1} )^2 \ 10[/tex]
v₂ = 0.4 m / s
The flow (Q) is defined as the amount of liquid that passes through the section of the pipe per unit of time, we can see that this is the same conservation of mass, therefore
Q = A v
Q = [tex]\pi \frac{d_2^2}{4} \ v_2[/tex]π d2 ^ 2 v2
Q = [tex]\pi \ \frac{0.1^2}{4} \ 0.4[/tex]
Q = 3.14 10⁻³ m ^ 3 / s
As the transported liquid is water
1 liter water = 1 kg
Consequently
1 m³ = 1000 liter = 1000 kg of water
Let's reduce the flow
Q = 3.14 10⁻³ m³/s ( [tex]\frac{10^3 kg}{1 m^3}[/tex] )
Q = 3.14 kg / s
In conclusion using the continuity equation we can find the results for the speed and flow of the outlet pipe are:
v₂ = 0.4 m / s Q = 3.14 kg / s
