Answer:
The easiest way to tackle this problem is by breaking the vectors up into their components (also it's easier to type this method).
G = 40.3 cos (-35.0°) i + 40.3 sin (-35.0°) j ----where i denotes the x direction and j denotes the y direction
H = 63.3 sin (270°) j ----- I left off the i component because i know cos 270 is 0.
40.3 and 63.3 are the magnitudes of your vector, or the hypotenuse of a triangle. We are finding the horizontal (Adjacent) and vertical (Opposite) legs the respective hypotenuse (we have to remember SOH COH TOA)
Now you can simply add components
G + H = (40.3 cos (-35.0)) i + (40.3 sin (-35.0°)+ 63.3 sin (270)) j ----be sure to pay close attention to signs when doing your calculations on your calculator.
The most common group of silicates is quartz. Silicate minerals is the most abundant mineral found in the crust. About 90% of the crust contains these minerals. Silicate minerals includes quartz, mica, feldspar, pyroxene, amphobole and olivine. About 12% of these silicates is quartz.
The set A intersection set B complements is {5, 12}.
<h3>What is a Venn diagram?</h3>
Venn diagram is an illustration that uses circles to show the relationships among set of numbers.
<h3>Elements in set A</h3>
A = {3,4,5,12}
<h3>Elements in set B</h3>
B = {3,4,7,14}
<h3>Set B complements</h3>
= {5, 8,12}
Set A intersection set B complements is calculated as follows;
= {3,4,5,12} ∩ {5, 8,12} = {5,12}
Thus, the set A intersection set B complements is {5, 12}.

Displacement = 0 (initial and final point are the same)
Distance=2AB
Average Speed=37.5km/h
Answer
a) Electron is moving toward right and brought to rest it means that force should be in opposite direction of motion electron.
We know F = qE here q = -e so, Force will be F = - eE.
Force on electron will be acting in opposite direction so, the electric field direction will be towards Right.
b) we know,
Force on electron = Electric force
m a = eE
using equation of motion
v² = u² + 2 a s
0 = (5.5 x 10⁵)² - 2 x a x 0.05
e = 1.6 x 10⁻¹⁹ C
mass of electron, m = 9.1.09 x 10⁻³¹ Kg
now,
E = 17.22 N/C
hence, strength of electric field is equal to E = 17.22 N/C
