Answer:
About 66 miles per hour
Explanation:
Based on the information given we can assume the car traveled the same number of miles every hour meaning all we need to do is divide.
400/6 ≈ 66 miles per hour
Vertical columns on the periodic table are called groups.

Answer:
Acceleration will 7.5 times g = 7.5 g
Explanation:
Centripetal acceleration is given by a = v²/r.
The speed in m/s will be; (96.6 Km/h )÷ 3.6
= 26.83 m/s.
Centripetal force = v²/r
= 26.83²/9.80
= 73.454 m/s²
But; g = 9.8 m/s²
Therefore the acceleration in terms of g will be;
= 73.454/9.8
= 7.5 g
Acceleration is 7.5 g
we are given in the problem the following dimensions or specifications
B = 0.000055 T r = 0.25 m constant mu0 = 4*pi*10-7
The formula that is applicable from physics is
B = mu0*I/(2*pi*r) I = 2*B*pi*r/mu0 I = 68.75 Amperes
