The velocity of the water jet discharging from the orifice can be obtained from v=\12ih, where h = 2 m is the depth of the orifice from the water surface. Determine the time for a particle of water leaving the orifice to reach point B and the horizontal distance x where it hits from surface.
The time for a particle of water leaving this orifice to reach point B and the horizontal distance are 0.553 seconds and 3.46 meters respectively.
How to calculate the time?First of all, we would determine the velocity of the water jet discharging from the orifice by using this formula:
V = √(2gh)
V = √(2 × 9.81 × 2)
V = 6.264 m/s.
Next, we would determine the time taken to reach point B as follows:
S = Sa + Uy(t) + ½at²
-1.5 = 0 + 0(t) + ½ × (-9.81) × t²
t = 0.553 seconds.
Now, we can determine the horizontal distance:

A transformer has 300,000 windings in its primary coil and uses 12,000V AC input. (4 points) How many windings would be needed to produce at output of 110V AC
Answer:
2750
Explanation:
The number of windings and the voltage are proportional.
__
Let n represent the number of windings to produce 110 Vac. Then the proportion is ...
n/110 = 300,000/12,000
n = 110(300/12) = 2750 . . . . multiply by 110
2750 windings would be needed to produce 110 Vac at the output.

Answer:
A. Blackhole
C. Physical disconnection/air gapping
D. Sandboxing
Here are the methods of containment based on the concept of isolation:
Physical disconnection/air gapping is the most effective method of isolation, separating the infected system from the rest of the network.
How does sandoxing work?Sandboxing isolates the infected system in a controlled environment, allowing analysis and cleaning without affecting the rest of the network. Quarantine isolates the infected system from the rest of the network until it can be cleaned, preventing it from infecting other systems.
The following methods are not based on the concept of isolation:
Blackhole: This is a method of redirecting malicious traffic to a dead end. This does not isolate the infected system, but it does prevent the malicious traffic from reaching other systems on the network.
Sinkhole: This is a method of redirecting malicious traffic to a honeypot. This does not isolate the infected system, but it does allow security researchers to collect information about the malicious traffic.
Therefore, the methods of containment based on the concept of isolation are Physical disconnection/air gapping, Sandboxing, and Quarantine.

Besides hev and ev motor systems themselves what other systems may use high voltage
Besides hev and ev motor systems themselves what other systems may use high voltage are the air conditioning compressor, auxiliary battery, and water pump.
Why an excessive voltage is used?
High voltages are utilized in transmission structures due to the fact a better voltage implies a decrease modern-day for a given energy of transmission. With a decrease modern-day, much less warmth is generated withinside the transmission traces and so much less electricity is wasted. Furthermore, it has superb environmental benefits.
To come up with a difficult estimate the common rated energy of the water pump is from 250 watts to 1500 watts. The smaller the water pump, much less is the wattage, much less is the energy consumption, subsequently low is the release and head.Usually, an auxiliary deliver is energy delivery that gives an auxiliary voltage.
