The needle on a compass always points in the direction of magnetic north because of the magnetic poles of earth. the compass is essentially a magnet itself, so the southern pole of the compass is attracted to the northern pole of earth.
I think is a high-pressure system because it is only in one particular area.
the resistance is 80.8Ω and average power 178.2 W
a) the value of resistance is given as,
R=rms voltage / rms current
and rms current = 2.1/√2
= I°/√2
rms current = 2.1/√2
rms current = 1.48
therefore R = 120/1.48
=80.4Ω
b) average power is product of rms current and rms voltage
P=120× 1.48
=178.2 W

Answer:255.255.255.224
Explanation:
/20 has a subnet mask of 255.255.240.0
We have 20 on bits for the network and 16 off bits for the host. Since the designer wants 20 to 30 hosts in each subnet we will be having 5 off bits for the host. Therefore we will be having a /27..
Which will be 255.255.255.224
