Answer:
The answer to your question is distance between these electrons
= 1.386 x 10⁻¹⁴ m
Explanation:
Data
Force = F = 1.2 N
distance = d = ?
charge = q₁ = q₂ = 1.602 x 10⁻¹⁹ C
K = 8.987 x 10⁹ Nm²/C²
Formula
-To solve this problem use the Coulomb's equation
F = kq₁q₂ / r²
-Solve for r²
r² = kq₁q₂ / F
-Substitution
r² = (8.987 x 10⁹)(1.602 x 10⁻¹⁹)(1.602 x 10⁻¹⁹) / 1.2
- Simplification
r² = 2.306 x 10⁻²⁸ / 1.2
r² = 1.922 x 10⁻²⁸
-Result
r = 1.386 x 10⁻¹⁴ m
Answer:
a)6.34 x 
W/m²
b)1.37 x 
W/m²
c) see explanation.
Explanation:
a)The relation of intensity'I' of the radiation and area 'A' is given by:
I= P/A
where P= power of sunlight i.e 3.9 x 
J
and the area of the sun is given by,
A= 4π
=> 4π
A=6.15 x 
m²
= 3.9 x / 6.15 x =><u> 6.34 x </u><u>W/m²</u>
b) First determine the are of the sphere in order to determine intensity at the surface of the virtual space
A= 4π
Now R= 1.5 x 
m
A= 4π x 1.5 x =>2.83 x 
m²
The power that each square meter of Earths surface receives
= 3.9 x /2.83 x =><u>1.37 x </u><u> W/m²</u>
<u />
c) in part (b), by assuming the shape of the wavefront of the light emitted by the Sun is a spherical shape so each point has the same distance from the source i.e sun on the wavefront.

Answer:
c. Both Technicians
Explanation:
A steering wheel position sensor is being discussed. Technician A says that the sensor is used to determine the direction of the steering wheel. Technician B says that the sensor detects how fast the steering wheel is turned. the following are used to sense
Hall-effect, Photo cell, Potentiometer are used on vehicles equipped with an electronically controlled suspension
sensors are like indicators in a vehicle to give signals for both direction and the speed of the vehicle
c. Both Technicians
