Answer:
-15.67287 N/C
Explanation:
= Location of electron =
= Location of electric field =
e = Charge of electron =
k = Coulomb constant =
Distance between the points is
Electric field is given by
The magnitude of the electric field is 15.67287 N/C
The direction is negative as the electron has negative charge.
Answer:
Option A: a_c = a_t
Explanation:
Let's denote the force acting on the car due to the truck as F_ct
Similarly, the force acting on the truck due to the car is denoted as F_tc.
Now, F_ct = m_c × a_c
Where;
m_c is mass of car
a_c is acceleration of car
Also, F_tc = m_t × a_t
Where;
m_c is mass of truck
a_c is acceleration of truck
Now, since the car is the one pushing the truck, from Newton's laws, we can say that they stick together and move in the same direction at the same acceleration.
Thus, the truck will move with an acceleration equal to that of the car pushing it.
Thus; a_c = a_t
Find the volume of the bottom and top separately and then add them.
Cylinder volume is the area of the bottom times the height
(22/7)(5^2)•175=13750 ft^3
The volume of a sphere is
V=(4/3)(22/7)r^3
where r is the radius. Here that's also 5 since it fits on the cylinder.
Also we only want half the sphere so use
V=(2/3)(22/7)•5^3=261.9 ft^3
Which we round upto 262.
Now add the parts together
13750+262=14,012 ft^3

Energy is passed through
Bcoz when you place a magnet close enough the magnet attracts or repals without any other fore we dont touch the magnet so it is non contact
