Answer:
If you know the total current and the voltage across the whole circuit, you can find the total resistance using Ohm's Law: R = V / I. For example, a parallel circuit has a voltage of 9 volts and total current of 3 amps. The total resistance RT = 9 volts / 3 amps = 3 Ω.

Answer:
<h2><em>
0.165Tesla</em></h2>
Explanation:
The Force experienced by the wire in the uniform magnetic field is expressed as F = BILsin∝ where;
B is the magnetic field (in Tesla)
I is the current (in amperes)
L is the length of the wire (in meters)
∝ is the angle that the conductor makes with the magnetic field.
Given parameters
L = 0.56 m
I = 2.6A
F = 0.24N
∝ = 90°
Required
magnitude of the magnetic field (B)
Substituting the given values into the formula given above we will have;
F = BILsin∝
0.24 = B * 2.6 * 0.56 sin90°
0.24 = B * 2.6 * 0.56 (1)
0.24 = 1.456B
1.456B = 0.24
Dividing both sides by 1.456 will give;
1.456B/1.456 = 0.24/1.456
B ≈ 0.165Tesla
<em>Hence the magnitude of the magnetic field is approximately 0.165Tesla</em>
Answer:
current = 2.67 A
Explanation:
we have given,
Q(t) = t³− 2t² + 4t + 1
to find I at t = 0.7s
we know
so,
current at t= 0.7s
I = 2.67 A
hence, current comes out to be 2.67 A
Answer:
Displacement from the starting position is 1224m
Explanation:
The object is moving at 120 meters per second, it does this for 10.2 seconds. Use multiplication to find the answer.
Weight of an object is defined as attraction force due to gravity
so here we will have
now we know that
mass = 15 kg
now acceleration due to gravity is given as
so here acceleration due to gravity is 9.8 m/s^2
