Answer:
The correct answer is in the x-axis direction, where the distance travelled is 1.0 cm and the surface is 8 
.
Explanation:
The electrical resistance is lower when the contact surface is larger and the length is shorter.
An electrical resistance is an opposition to the flow of electric current through a conductor. For a given conductor, the resistance is given by the following formula:
R = ρ * 
Where:
R: Electrical resistance.
ρ: Resistivity of the material.
l: Length.
S: Surface of the conductor.
Thus, the direction in which the electrical resistance is lower is when the distance is minimum and the area is greater.
Have a nice day!

the car continues in a straight path from the point at which it encountered the ice
Answer:
The correct answer is option 'c': Smaller stone rebounds while as larger stone remains stationary.
Explanation:
Let the velocity and the mass of the smaller stone be 'm' and 'v' respectively
and the mass of big rock be 'M'
Initial momentum of the system equals
Now let after the collision the small stone move with a velocity v' and the big roch move with a velocity V'
Thus the final momentum of the system is
Equating initial and the final momenta we get
Now since the surface is frictionless thus the energy is also conserved thus
Similarly the final energy becomes
\
Equating initial and final energies we get
Solving i and ii we get
Using this in equation i we get
Thus putting v = -v' in equation i we get V' = 0
This implies Smaller stone rebounds while as larger stone remains stationary.
Newton was given the title "scientist" when he was given the Merit Badge at the age of 15. He continued to work in the field of science, and was considered a scientist until his death at the age of 84. That is a total of 69 years of work. Hope this helps!
Answer:

Work :
W = Fd (work = force x distance)
Force :
F = W/d
Distance :
d = W/F
