Answer:
Explanation:
a) series resistors carry the same current
A = V/Re = 6/(16 + 6) = 0.2727272... ≈ 27 mA
b) V = V₀(R/Re) = 6(16/(16 + 6)) = 4.363636 ≈ 4.4 V
c) V = V₀(R/Re) = 6(6/(16 + 6)) = 1.636363 ≈ 1.6 V
or V = 6 - 4.4 = 1.6 V
Since in an electromagnetic wave the electric and magnetic fields are perpendicular to each other and perpendicular to the direction of motion, the electric field has to point in the z direction.
For a 650-kg satellite is in a circular orbit about Earth at a height above Earth equal to Earth’s mean radius, the resultant values are is mathematically given as
- V=5.59*10^3m/s
- T=3.98hours
- F=1.47*10^3N
<h3>What are the satellite’s orbital speed, the period of its revolution, and the gravitational force acting on it.?</h3>
Generally, the equation for satellite orbital speed is mathematically given as
a)
V=5.59*10^3m/s
b)
T=3.98hours
c)
Therefore
F=1.47*10^3N

Answer:
The motorbike is traveling at 40 m/s
Explanation:
100m over 2.5 seconds or 100/2.5 is 40 m/s
Answer:
The expression for resistance is
Explanation:
Generally flow of charge at that point is mathematically given as
Where L is length of the cylinder as given the question
The potential difference that is between the cylinders is
Where is the radius
Where E is the electric field that would be experienced at that point which is mathematically represented as
Where is the is the resistivity as given the question
considering the formula for potential difference we have
To get V we integrate both sides
According to Ohm law
Now making R the subject we have
Substituting for V
