Answer:
Torque = 0.47 Nm
Explanation:
Torque = BIAsin∅
Since the plane is parallel to the magnetic field, ∅ = 90⁰
sin 90 = 1
Magnetic field, B = 0.30 T
current, I = 2.0 A
Radius, R = 0.50 m
A = πR²
A = π(0.5)² = 0.785 m²
Torque = 0.3 * 2 * 0.785
Torque = 0.47 Nm
E = 1/2 kx^2
Make k the subject of formula.
Find the base units of E and x.
Replace back in the equation and find the base units of k.

Answer:
C = A - B
Explanation:
The addition of vectors takes into account the magnitude of each vector and its direction, so when adding two vectors, the result depends on the direction of the vectors.
* If the vectors have the same direction the result is maximum
C = A + A
* if the vectors have 90 between them, the magnitude of the result is given by the Pythagorean Theorem
C = √(A² + B²)
* if the vectors have 180º between them the result is minimal
C = A - B
We can also perform this sum graphically, where the resulting vector goes from the origin of the first vector to the tip of the last one, it can clearly be seen that when the vectors are antiparallel (180º angle) the magnitude is minimal
Answer:
<h2>7.5 J</h2>
Explanation:
The work done by an object can be found by using the formula
workdone = force × distance
From the question we have
workdone = 10 × 0.75
We have the final answer as
<h3>7.5 J</h3>
Hope this helps you
