Let you be at point A while your friend be at point B,
while you are still having lunch,
you friend travels= 27/60*75miles/h=33.75miles
Remaining Distance= 135miles-33.75miles=101.25miles
Take note here is the tricky part, for the remaining distance both you and your friend are driving towards each other,
So first,
Total speed =Adding both ur friend and ur speed= 60+75=135miles/h
Time taken to meet= 101.25miles/135miles/h=0.75h
Total hours ur friend drives= 0.75h+27/60h=1.2h
total distance ur friend drove= 1.2h * 75miles/h= 90km
for the part how far u travelled,
simply take 135miles -90miles=45miles
Answer:
The value is 
Explanation:
From the question we are told that
The length is 
The radius of the the solenoid is 
The number of turns per meter is 
The current through the solenoid is 
The current through the segment is 
Generally the magnetic force is mathematically represented as
At maximum 
So
Here B is the magnetic field is mathematically represented as
Here 
is the permeability of free space with value
So
=> 
So
<span>There is no special name for that. Physics is usually just concerned with "forces", and doesn't specify whether the force pushes or pulls. If you want to be more specific, you can just call it a "pulling force".
I hoped this was satisfying!:)</span>
The correct answer is <em>"Thermal".</em>
