If Frank leaves Gainesville at 7:30 am, the time he should arrive in Tampa is 12.00 pm after spending 4 hours 30 minutes on the road.
<h3>What is average speed? </h3>
The average speed of an object is the ratio of total distance to total time of motion.
V = total distance/total time
For Frank to be in Tampa by noon, he must spend atleast 4 hours 30 minutes on the road.
18.3 mph = d/4.5 h
d = 82.35 miles
The distance between Gainesville and Tampa is 82.35 miles.
Thus, we can conclude that, if Frank leaves Gainesville at 7:30 am, the time he should arrive in Tampa is 12.00 pm after spending 4 hours 30 minutes on the road.

Answer:
B. Kinetic energy.............
Answer:
False
Explanation:
parts that are smaller than protons neutrons and electrons
Answer:
I think it's because it's an insulator and like charges attract
(a) The magnitude of the force that the magnetic field exerts on the loop is 0.042 N.
(b) The direction of the force that the magnetic field exerts on the loop will be out of the plane.
<h3>
Magnetic force exerted on the loop</h3>
F = BIL
where;
- I is current in the loop
- L is length of the loop
emf = BVb
where;
- b is breadth of the loop
- V is velocity
- B is magnetic field
emf = 2.6 x 3 x 0.018 = 0.1404 V
Current in the loop, I = emf/R = 0.1404/0.8 = 0.18 A
<h3>Magnetic force</h3>
F = BIL
where;
F = 2.6 x 0.18 x 0.09 = 0.042 N
<h3>Direction of the force</h3>
The direction of the force that the magnetic field exerts on the loop will be out of the plane.
