Answer:
A torque of 102.5375 Nm must be exerted by the fireman
Explanation:
Given:
The rate of water flow = 6.31 kg/s
The speed of nozzle = 12.5 m/s
Now, from the Newton's second law we have
The reaction force to water being redirected horizontally (F) = rate of change of water's momentum in the horizontal direction
thus we have,
F = 6.31 kg/s x 12.5m/s
or
F = 78.875 N
Now,
The torque (T) exerted by water force about the fireman's will be
T = (F x d)
or
T = 78.875 N x 1.30 m
T = 102.5375 Nm
hence,
<u>A torque of 102.5375 Nm must be exerted by the fireman</u>
A circuit computes various types of Boolean operations. As in the question no specific circuit has been shown,so we have to know the fundamental logic operations.
Out of the various types of logic operations in Boolean algebra,the simple operations are- addition,subtractions,multiplications,division through logic gates.
Various logic or Boolean operations are NOT GATE,OR GATE ,AND GATE .
There are other operations also like NAND GATE,NOR GATE and XOR GATE etc
NOT gate is the simple logic gate which inverts one quantity.it makes 1[high] to 0[low] and vice versa.
OR gate gives 1 [high] when one of the input is 1 and low when all the inputs are low.
AND operation gives 1 when all the inputs are high and low when one of the input is low
NAND operation is AND gate followed by a NOT gate
NOR operation is the OR gate followed by a NOT gate.
Remembering these simple rules we can get the idea of the operations involved in the circuit. Each circuit has different symbols and gives different results.
One atom on nitrogen because there isn’t a number directly after it’s the 3 signifies that there is three groups of those atoms as a total
