Answer:
Explanation:
Magnetic field due to a long current carrying wire can be calculated as follows .
B = 10⁻⁷ x 2I / d where B is magnetic field , I is current .
The wire is along x -axis and the point is on y-axis at a distance of 0.8 m
Magnetic field at point of .8 m on y -axis
B₁ = 10⁻⁷ x 2 x 39 / 0.8
= 97.5 x 10⁻⁷ T .
Second wire is parallel to z-axis and passes through point on y-axis at a distance of 4.4 m . So the given point is at a distance of 4.4 - .8 = 3.6 m
Magnetic field
B₂ = 10⁻⁷ x 2 x 47 / 3.6
= 26.11 x 10⁻⁷ T .
Both these magnetic fields are perpendicular to each other so
Resultant magnetic field
B = √ ( 26.11² + 97.5² ) x 10⁻⁷ T
= √( 681.73 + 9506.25 ) x 10⁻⁷ T
= √( 10187.98) x 10⁻⁷ T
= 100.93 x 10⁻⁷ T .

Answer:
-64.0 m/s²
Explanation:
v = 32.0 t − 2.00 t³
Acceleration is the derivative of velocity.
a = dv/dt
a = 32.0 − 6.00 t²
At maximum displacement, v = 0 and a < 0.
v = 0
32.0 t − 2.00 t³ = 0
2.00 t (16.0 − t²) = 0
t = 0 or 4.00
When t = 0 s, a = 32.0 m/s².
When t = 4.00 s, a = -64.0 m/s².
The maximum displacement is at t = 4.00 s. Therefore, the acceleration at that moment is -64.0 m/s².
