Answer:
Explanation:
The magnitude of the force of a moving cahrge, in our case a proton, trought a magentic field is given by:
(1)
where:
q is the proton charge (
)
v is the proton velocity (
)
B is the magnetic field (B = 1.17 T)
Now, we just need to solve the equaton (1) for \theta.

But the force F = ma, then:
m is the mass of proton (
)
a is the acceleration (
)

I hope it helps you!
Note that Speed = Distance/Time.
1st trip:
Distance = 30 mi
Time = 30 min = 0.5 h
Speed = 30/0.5 = 60 mi/h
2nd trip:
Distance = 50 mi
Time = 1 hour
Speed = 50 mi/h
3rd trip:
Distance = 30 mi
Time = 30 min = 0.5 h
Speed = 30/0.5 = 60 mi/h
Average speed = (60 + 50 + 60)/3 = 56.7 mph
The closestanswer is 55 mph
Answer: 55 mph
Answer: D, Refraction, Reflection, Refraction.
Explanation: Refraction is a rainbow. See image for info.
As the engine heats up, a natural circulation starts, as coolant rises through the engine block by convection. It passes through the top hose, and into the radiator. Inside the radiator, heat is removed from the coolant as it falls from the top to the bottom.

The intensity of a sound wave is defined as the amount of energy passing through a unit area of the wave front in unit of time.
