D) Kirchhoff’s junction rule states that at any junction, the sum of the altimeter attained moving into and out of that junction are equal.

While

Kirchhoff’s loop rule states that the algebraic sum of the number of lifts used in any closed loop is equal to zero

Explanation:

Given that the lifts are analogous to batteries, and the runs are analogous to resistors. 

So from all the figures. The resistors represent the runs while the lift represents the battery.

Kirchhoff’s junction rule states that at any junction, the sum of the altimeter attained moving into and out of that junction are equal.

While

Kirchhoff’s loop rule states that the algebraic sum of the number of lifts used in any closed loop is equal to zero

Doc Brown has calculated his Delorean can accelerate at a rate of 2.52 m/s/s. How
GREYUIT [131]

Answer:

304.89m

Explanation:

Given

acceleration a = 2.52m/s²

final speed v = 39.2m/s

initial speed = 0m/s (car accelerates from rest)

Using the equation of motion below to get the distance of Doc brown from Marty;

v² = u²+2as

substitute the given parameters

39.2² = 0²+2(2.52)s

1536.64 = 0+5.04s

divide both sides by 5.04

1536.64/5.04 = 5.04s/5.04

rearrange the equation

5.04s/5.04 = 1536.64/5.04

s = 304.89m

Hence He and Marty must stand at 304.89m to allow the car to accelerate from rest to a speed  of 39.2 m/s?
