Answer:
Electric potential, 
Explanation:
It is given that,
The magnitude of electric field, 
Distance between automobile engines that consists of metal conductors, 
Let V is the magnitude of the potential difference between the conductors. The relation between the electric field and the electric potential is given by:



So, the magnitude of the potential difference between the conductors is
. Hence, this is the required solution.

Given:
mb=2.05 kgmb=2.05 kg Mass of the book
fs=2.45 Nfs=2.45 N Static friction
fk=1.50 Nfk=1.50 N Kinetic friction
Answer:
Dy = 111.66 [m]
t = 3.5 [s]
Explanation:
To solve this problem we must use the equations of kinematics.

where:
Vf = final velocity [m/s]
Vo = initial velocity = 27 [m/s]
g = gravity acceleration = 9.81 [m/s²]
t = time = 3.5 [s]
Note: The negative sign of the equation means that the gravity acceleration goes in opposite direction
Vf = 27 - (9,81*3,5)
Vf = - 7.33 [m/s] (this negative sign indicates that at this moment the snowball is going downwards)
To find how high the snowball was we must use the following equation:

Dy = (27*3.5) + (0.5*9.81*3.5)
Dy = 94.5 + (17.16)
Dy = 111.66 [m]
Under the Big Top elephant, Ella (2500 kg), is attracted to Phant, the 3,000 kg elephant. They are separated by 8
Explanation:
u = 0m/s
v = 30m/s
a = 2m/s²
Using Kinematics, we have v = u + at.
Therefore t = (v - u) / a
= (30 - 0) / (2) = 15 seconds. (B)
