Answer:
force on the wire of section cm will be 
Direction of force on the wire will be in south direction
Explanation:
We have given current in the wire i = 1 A
Magnetic field strength B = 0.6 T
We have to find the force on 1 cm section of the wire so l = 1 cm = 0.01 m
Force on the wire containing current is equal to
So force on the wire of section cm will be
Direction of force on the wire will be in south direction
It states that the total entropy of an isolated system can never decrease over time
Answer:
<u>We are given:</u>
initial velocity (u) = 20m/s
acceleration (a) = 4 m/s²
time (t) = 8 seconds
displacement (s) = s m
<u />
<u>Solving for Displacement:</u>
From the seconds equation of motion:
s = ut + 1/2 * at²
replacing the variables
s = 20(8) + 1/2 * (4)*(8)*(8)
s = 160 + 128
s = 288 m
If it is the same vehicle, then the 60mph vehicle has more kinetic energy since it is moving faster. Therefore, it requires more energy to stop, and if it is the same car with the same beak system, the braking distance of the 30mph car will be significantly shorter than the 60mph car.
