Answer:
Water leaves the sprinkler at a speed of 2.322 m/sec
Explanation:
We have given internal diameter of the garden
Speed of water in the hose is
Number of holes n = 22
Diameter of each holes
According to continuity equation
So water leaves the sprinkler at a speed of 2.322 m/sec
In a forward bias, the p-type is connected to the positive side of the terminal and the n-type is connected to the negative terminal of the voltage source. The electrons in the n-type junction travels towards the holes in the p-type junction
In a reverse bias, the junctions are connected to the opposite terminals compared to the forward bias. The free electrons build up on the center creating a neutral layer that widens as voltage is increased.
Explanation:
The average speed is the displacement of a particle divided into a time in which the displacement occurs. Instead, instantaneous speed is the limit of the average speed as the time interval approaches zero.
<u><em>In physics expressions </em></u>
Instantaneous speed=
b) Speed denotes distance traveled divided by time, and instantaneous speed measures how quickly and in which direction does it move
Answer:
a) 2250 J
b) 0 J
c) 2250 J
Explanation:
a) Since, the process is isochoric
the change in internal energy
Here, n = 0.2 moles
Cv = 12.5 J/mole.K
We have to find T_f so we can use gas equation as
So,
b) Since, the process is isochoric no work shall be done.
c) By first law of thermodynamics we have
Since, Q is positive 2250 J of heat will flow into the system.
