D is the answer
Imagine the magnetic field, it emanates from both
Answer:
a. Time=25seconds
b.distance=1041.67m
Explanation:
a.The equation for
in terms of m/s is
after conversion.
To find when speed reaches 300km/hr=83.33m/s, we find
and solve for 

b. From a, above we already have our t=25seconds as the time it takes before the plane is airborne.
#To find distance travelled in that time , we substitute for
in our distance equation:

Hence the distance of the plane before it gets airborne is 1041.67m
Ampere per meter squared A/m
The answer is this, but i don't know how to simplify it. 3x^100000000<span />
Answer:
610 meters.
Explanation:
Because Jim released the accelerator, the truck started to slow down, so the friction force will eventually stop the truck.
the kinetic energy of the truck just after Jim released the pedal is:

The work done by the friction force is given by:
