Answer:
30Ω
Explanation:
To calculate the equivalent resistance in the circuit, do the following:
Step 1:
10Ω and 20Ω are in series connection. Therefore their equivalent is: 10 + 20 = 30Ω
Step 2:
The equivalent resistance (30Ω) obtained from the above is in parallel connection with 30Ω resistance shown in the diagram above.
Therefore their equivalent is given by:
1/30 + 1/30 = 2/30 = 1/15.
Now invert to obtain the equivalent
Therefore, the equivalent is 15Ω
Step 3:
Determination of the overall equivalent of the resistance of the circuit.
The new equivalent resistance 15Ω obtained above is in series connection with 15Ω resistance in the diagram above.
Therefore their equivalent is given by:
15Ω + 15Ω = 30Ω
Therefore, the equivalent resistance in the circuit is 30Ω

Answer:
F = Bev
Explanation:
B is magnetic field density
e is the electron charge
v is the electron velocity
First, let us calculate the total distance that each have
taken after 2 hours.
Let’s say that:
A = sailboat which sails at 23 mph in a direction 330°
B = sailboat which sails at 34 mph in a direction 190°
Calculating for distances:
dA = 23 mph (2 hours) = 46 miles
dB = 34 mph (2 hours) = 68 miles
Imagining a Cartesian coordinate, the angle θ
between the two sailboats is simply the difference:
θ = 330°
- 190°
θ = 140°
We know that from the law of cosines:
c^2 = a^2 + b^2 – 2 a*b*cos θ
Therefore the
distance between the two after 2 hours, C, is:
C^2 = 46^2 +
68^2 – 2 (46) (68) cos(140)
<span>C = 107.39 miles</span>
