b) between poles M1 and M2
Explanation:
From the expression, we can deduce that r is the distance between two magnetic poles M1 and M2.
The law of attraction between two magnetic poles states that:
<em> the force of attraction or repulsion between two magnetic poles is a function of the product of the strength of the magnetic poles and the square of the distance between the pole</em>s
Mathematically:
FM = K
here r is the distance between the poles
FM is the magnetic force between the poles
M1 is the strength of the first magnetic pole
M2 is the strength of the second pole
K is the magnetic field constant

Answer:
a = 6.53 m/s^2
v = 11.5689 m/s
Explanation:
Given data:
engine power is 217 hp
70 % power reached to wheel
total mass ( car + driver) is 1530 kg
from the data given
2/3 rd of weight is over the wheel
w = 2/3rd mg
maximum force
we know that F = ma
the new power is
solving for speed v
v = 11.5689 m/s
Answer:
(a) 16.777mi
(b)Yes, he was speeding
Explanation:
(a)
Let's do the proper operations in order to convert km to mi:
We can conclude that the trip length in miles was:
(b)
Let's calculate the speed of the man during the trip:
But first, let's do the proper operations in order to convert min to h:
Now, the speed is:
As we can see:
So, we can conclude that the driver was speeding
