Answer:
376 miles
Explanation:
speed = distance / time
therefore distance = speed * time
distance = 40 miles/hr * 9.4 hr
then
distance = 375 miles

It would increase--materials expand as they get hotter.
The electrostatic force is 9 x 10¯³ N.
We need to know about electrostatic force to solve this problem. The electrostatic force is applied on a charge which has near position to another charge. It can be determined by
F = k Q1 . Q2 / r²
where F is electrostatic force, k is Coulomb constant (9 x 10⁹ Nm²/C²), Q1 and Q2 are the charges and r is the radius or distance between the charges.
From the question above, we know that
Q1 = -10 nC = -10 x 10¯⁹ C
Q2 = -10 nC = -10 x 10¯⁹ C
r = 1 cm = 0.01 m
By substituting the following parameters, we can calculate the electrostatic force
F = k Q1 . Q2 / r²
F = (9 x 10⁹ . 10 x 10¯⁹ . 10 x 10¯⁹ / (0.01)²
F = 9 x 10¯³ N
Hence, the electrostatic force is 9 x 10¯³ N.
