Answer:
Explanation:
Given that,
The length of tension wire is 10m
L = 10m
It caries a current of 10A
I = 10A
The current is perpendicular to the magnetic field
B = 5.5 × x10⁻⁵ T.
Then, θ = 90°
The magnetic force that act on the line is?
F = i(L × B)
L × B = LB Sinθ
Where
I is the current
L is the length of the wire
B is the magnetic field
θ is the angle between the field and the direction of the length.
Then,
F = I × L × B × Sinθ
F = 10 × 10 × 5.5 × x10⁻⁵ × Sin 90
F = 5.5 × x10⁻³ N
Then, the magnetic force experience on the line is 5.5 × x10⁻³N

Answer:
4 seconds
Explanation:
Start with this observation: the distance traveled by car A, plus the distance traveled by car B, plus the original 15 meter gap, equals the 55 meter separation at time t.
dA + dB + 15 = 55
You're given the equation for distance traveled at constant acceleration when the initial velocity is 0:
d = 0.5at²
Given that the acceleration of car A is 2 m/s² and the acceleration of car B is 3 m/s², all you have to do is plug in the expressions and variables and solve for t.
0.5 (2) t² + 0.5 (3) t² + 15 = 55
t² + 1.5 t² = 40
2.5 t² = 40
t² = 16
t = 4
