You have to attach something if your using a picture there is no problems there
Answer:
yes
Explanation:
yes, because lets say you were a surgeon you would have sharp tools floating everywhere
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
Answer:
F = 339.23 N
Explanation:
Weight of a car, W = 1050 N
Initial velocity, u = 0
Final velocity, v = 42 m/s
Time, t = 13 s
The weight of an object is given by :
W = mg
g is the acceleration due to gravity
The force acting on car is :
So, the force acting on the car is 339.23 N.
