To solve the problem it is necessary to take into account the concepts related to the Magnetic Force, which is given by,
Where
F= Magnetic force
q= charge of proton
v= velocity
B Magnetic field
Angle between the velocity and the magnetic field.
Re-arrange the equation to find the angle we have,
Replacing our values we have,
Then,
The angle between 0 to 180 degrees would be,
Therefore the two angles required are 13.63° and 166.36°
Answer:
Cost = $ 3,995
Explanation:
Let's start by looking for the energy consumed, which is the power over time
E = P t
The power is 65 W, the time is 12 h each day, in a period of 30 days the time is
t = 12 30 = 360 h
E = 65 360
E = 23,500 W h
We reduce to KW h
1 kW = 1000 W
E = 23.5 kW h
Let's use a direct ratio rule (rule of three) to find the cost
Cost = 23.5 17.0
Cost = 399.5 c
Cost = $ 3,995
Answer:
0.7757 rev/s
Explanation:
d = Diameter of the tornado = 53 m
r = Radius of the tornado = 53/2 = 26.5 m
v = Velocity of wind = 465 km/h
Converting velocity to m/s
Angular velocity
∴ Angular velocity is 0.7757 rev/s
The answer is
<em>All the three light bulbs will glow</em>
hope this helps
