Field strength = (15 V) / (4 cm)
Field strength = (15 V) / (0.04 meter)
Field strength = (15/0.04) (volts/meter)
<em>Field strength = 375 volts/meter </em>
Answer:
<h2>
The magnitude of the magnetic is 0.145 T</h2>
Explanation:
Given :
Speed of proton 
Mass of proton 
Kg
The force on the proton in magnetic field is given by,
But 
(∵ Force is perpendicular to the velocity so 
)
When particle enter in magnetic field at the angle of 90° so particle moves in circle
So force is given by,
Where 
radius but in our case 0.23 m, 
C
By comparing above two equation,
T
Answer:
Average speed of Elain = 60 km/h
Explanation:
Total Distance covered by Jack = 360km
Average Speed of Jack = 80 km/h
Time taken by Jack to complete his journey = Distance / Average speed = 360 km / 80 km/h
Time taken by Jack to complete his journey = 4.5 hours
As it is given the both Jack and Elain travelled the same amount of distance:
Total distance travelled by Elain = 360 km
It is given that Elain took 1.5 hourse more than Jack to cover the distance, so Time taken by Elain to cover the distance is = 4.5 hours + 1.5 hours = 6 hours
Average speed of Elain = Distance/ time = 360 km / 6 hours
Average speed of Elain = 60 km/h
U can always just do the classic roller coaster going up an incline and create some sort of story from that.
see i was trying to figure out the answer but i didn't understand it so i took the time to research and work it out but i still didn't understand i found one that was close to it and i got the same one as the other person which is D but idk if it is that type of question if it is than it is d if not then idk
