Answer:
that technician A is right
Explanation:
The test lights are generally small bulbs that are turned on by the voltage and current flowing through the circuit in analog circuits, these two values are high and can light the bulb. In digital circuits the current is very small in the order of milliamps, so there is not enough power to turn on these lights.
From the above it is seen that technician A is right
Ulama is similar Racquetball
Answer:
The new pressure is 4 times of the initial pressure.
Explanation:
Given that,
The pressure of an ideal gas is 4 atm.
We need to find the change in the pressure of the gas if the temperature by a factor of 4.
We know that,
PV = nKT ....(1)
P = pressure, V = volume, T = temperature
Let P' is the new pressure of the gas. So,
P'V= nK(4T) ......(2)
Dividing equation (1) and (2) we get :
It means that the new pressure is 4 times of the initial pressure.
